The present disclosure concerns embodiments of multi-lumen cannulae that can be used in various different medical procedures. The multi-lumen cannulae can comprise an elongated body comprising multiple different ports that connect to various different sidewall lumens contained within the elongated body. The multi-lumen cannulae can also comprise a central lumen that extends through the entire elongated body and can be fluidly connected to the various different sidewall lumens. The multi-lumen cannulae can further comprise two balloons on an exterior of the elongated body, which can be used to isolate a right atrium of a patient's heart.

Multi-lumen cannulae

A multiple-firing clip device includes a hollow shaft defining a lateral opening communicating with an environment and a distal shaft portion between the lateral opening and a distal end opening. A shuttle longitudinally moves on the shaft and comprises a shuttle body defining a lumen surrounding the shaft, a snare, and a snare-extender slide defining a snare track to form a snare travel path in which the snare is disposed from the body and through the track and a portion of the body. The slide moves along a given extent defining a slide distance and a distal end and movement of the slide to the distal end shortens the snare travel path to extend the snare portion through the lateral opening, through the distal shaft portion, and distally out from a distal side of the body longer than the given extent to secure a suture with the snare.

Multiple-firing suture fixation device and methods for using and manufacturing same

A knotless suture fastener installation system for securing medical devices such as cardiac implants. The knotless suture fasteners may be spring-biased so as to grip onto sutures passed therethrough. The system includes a fastener deployment tool with a proximal handle and a distal shaft to which a fastener cartridge attaches. A plurality of disposable cartridges are sequentially attached to the end of the deployment tool and used to secure the medical implant one fastener at a time. The deployment tool may also cut the sutures being fastened.

Knotless suture fastener installation system

A device for deploying a suture clip onto a suture can include a proximal handle portion that includes an actuation mechanism. The device can also include an outer shaft defining an inner lumen. A crimping assembly can be at least partially disposed within a distal end of the outer shaft. The crimping assembly can include a plurality of crimping members configured to receive and radially compress a suture clip. The actuating mechanism can be configured to move the plurality of crimping members radially inwardly from a first position, where the crimping members are configured to receive a suture clip, to a second position where the plurality of crimping members are configured to radially compress the suture clip, causing the suture clip to plastically deform and become secured around one or more sutures.

Suture clips, deployment devices therefor, and methods of use

In one embodiment, a multi-layer suture fastener that includes a generally disc-shaped body defining a plurality of axially spaced-apart layers. Each layer can include an inner axial surface and an outer axial surface. A suture opening can extend from the inner axial surface to the outer axial surface of each layer. The suture openings can have an open configuration and a closed configuration. One or more lines of suture can be passed through the suture openings when in the open configuration. The suture openings can be placed in the closed configuration. In the closed configuration, the one or more lines of suture can be restricted by radial surfaces of the suture opening from sliding through the suture openings in at least one longitudinal direction of the one or more lines of suture.

Suture fastener having spaced-apart layers

Disclosed herein are annular prosthetic devices, such as annuloplasty rings, that include suture clips integrated into or mounted within an annular frame. The clips can quickly secure to sutures to obviate the need to tied knots in the sutures during implantation. Embodiments comprise an annular frame having an open central region and a plurality of suture clips spaced angularly apart around the frame. Each of the suture clips can comprise two opposing tabs that extend toward each other such that the suture clip forms a gripping region between ends of the tabs and the gripping region is configured to grip a suture inserted through the suture clip between the two tabs. The annular frame and the plurality of suture clips can be formed from a single piece of flat material with the suture clip tabs being formed by laser cutting the piece of flat material, or the suture clips can be movable along a track formed in the annular frame.

Annulus rings with suture clips

Disclosed suture clips include a generally disk-shaped body having an annular outer body, first and second tabs extending radially inwardly from opposing sides of the annular outer body, first and second slots passing through a thickness of the suture clip and separating the annular outer body from lateral sides of the first and second tabs, and the first and second slots include stepped portions configured to align the suture clip on a rail of a clip deployment device. The stepped slots create bracketing surfaces that interface with the rail on which the clips are mounted, such that the bracketing surfaces prevent or limit the freedom of the clips from tilting or shifting relative to the rail. The disclosed clips can also include rounded edges on engagement surfaces of the tabs to minimize particulate formation.

Suture clips

Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

Suture clip deployment device

Disclosed herein are embodiments of spring cannulae, including one or more holes in the sidewall of the cannula. Some disclosed cannulae include a wire, helically wound to form coils, and at least one hole in the cannula that interrupts one or more of the coils. Some embodiments further include a fused region of the coils through which the hole passes. Some embodiments include a ring attached to ends of the interrupted coils, where the hole is surrounded by the ring. Some embodiments include a sheath that is attached to a radial surface of the interrupted coils, where the hole passes radially though the sheath.

Spring cannulae

Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

Suture securement devices

Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.

Suturing devices for heart valve surgery

Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can then move distally to prepare to deploy the next suture clip.

Described herein are reusable surgical needles having a resiliently collapsible rear loop that captures a suture as it is passed through an object and resiliently expands upon exiting the object to release the suture. Also described are suture spool assemblies that include a rigid housing and a rotatable spool of suture material suspended within the housing so that a plurality of sutures can be dispensed from the assembly in succession during a surgery. Also described are annular pledgets having diametrical dimensions similar to an outer ring of a cardiac implant such that a single annular pledget can be used with a plurality of sutures that secure the cardiac implant to native tissue around the perimeter of the cardiac implant. Related methods of suturing cardiac implants are also disclosed.
