A method of removing needles operatively associated with suture through tissue surrounding an access tract, the method comprising advancing an elongate distal member along the access tract, locating an elongate proximal member in contact with tissue surrounding the puncture site, the elongate proximal member comprising a guide disposed within the elongate proximal member, a perimeter of the guide forming a plurality of needle receiving gaps that are circumferentially spaced about a needle deployment actuator with a portion of the guide disposed between adjacent needle receiving gaps extending outwardly towards a wall of the lumen of the elongate proximal member, the needle deployment actuator extending to the elongate distal member and being configured to initiate proximal movement of a needle toward an opening of the elongate proximal member, and actuating the needle deployment actuator to move the needle toward the opening of the elongate proximal member.

Needle harvesting devices, systems and methods

A suturing system including an elongate distal member and an elongate proximal member proximal the elongate distal member, the elongate proximal member having a lumen. A needle deployment actuator extends to the elongate distal member and is configured to initiate proximal movement of a needle toward an opening of the elongate proximal member. A guide is disposed within the elongate proximal member, a perimeter of the guide forming a plurality of needle receiving gaps that, when viewed in cross-section, are circumferentially spaced about the deployment actuator with a portion of the guide disposed between adjacent needle receiving gaps extending outwardly towards a wall of the lumen of the elongate proximal member.

A suturing system including a sheath, a handle assembly proximal the sheath, an elongate body disposed between the sheath and the handle, a plurality of needles disposed distal the elongate body in a pre-deployed configuration and movable into the elongate body in a deployed configuration, each of the plurality of needles including a needle tip, each needle tip being orientated proximally towards the elongate body in the pre-deployed configuration, and a needle capture assembly disposed between a distal end of the elongate body and the handle, the needle capture assembly including two needle engaging edges longitudinally spaced with respect to each other, with each being configured to interlock with at least one of the plurality of needles.

Suturing systems and methods

A medical device including an elongate member extending from a proximal end toward a distal end, the elongate member having a lumen with a longitudinal axis, a hub portion towards the proximal end of the elongate member and configured for a user to hold and manipulate a position of the elongate member, a base portion including a first groove and a second groove separated by an opening, and two wings disposed towards a distal end of the medical device, the two wings being opposite each other across the longitudinal axis and on opposite sides of the base portion, wherein, the two wings are configured to move in relation to the longitudinal axis and wherein each wing has an elongate slot having a closed first end at a location between the base portion and a peripheral end of the wing.

A suturing system including an elongate distal member, an elongate proximal member proximal the elongate distal member, and a needle guide disposed between the elongate distal member and the elongate proximal member. A plurality of needles with a needle tip of each needle of the plurality of needles are orientated generally proximally toward a single opening in a distal end of the elongate proximal member. When the needle tip of each of the plurality of needles is at least partially disposed within the single opening, a portion of each needle of the plurality of needles, proximal a distal end of the needle guide, being radially separated by a distance less than a diameter of the elongated proximal member.

A suturing system is provided. In an embodiment, the suturing system includes a sheath having a proximal end and a distal end. A needle is disposed distal the sheath in a pre-deployed configuration with a needle tip of the needle being orientated proximally towards the sheath. A body is disposed within the sheath, the body comprising a guide reducing an outer cross-sectional dimension of the body at the guide and forming a space between the body and the sheath, the guide being configured to receive the needle and direct the needle proximally toward the proximal end of the sheath. A suture is attached to the needle.

A needle removal device is provided for removing needles from suturing devices and/or systems. In an embodiment, the needle removal device may be intended for use with a suturing device having one or more needle lumens. The needle removal device may include a first member having a first plurality of needle receptacles extending therethrough. The first needle receptacles may be configured and positioned to correspond to one or more of the one or more needle lumens of the suturing device. The needle removal device may also include a second member having a second plurality of needle receptacles extending therethrough. At least one of the first member or the second member may be moveable between a first position, wherein the first needle receptacles and the second needle receptacles are substantially aligned, and a second position, wherein the first needle receptacles and the second needle receptacles substantially unaligned.

Needle harvesting devices, systems, and methods

A needle removal device is provided for removing needles from suturing systems. In an embodiment, the needle removal device may include a base member configured to be selectively positioned substantially adjacent a proximal portion of a suturing system. The proximal portion of the suturing system may include a plurality of needle lumens. The needle removal device may also include a plurality of needle receptacles at least partially defined by the base member. The needle receptacles may be positioned and configured to generally correspond to the needle lumens of the suturing system. The needle receptacles may be further configured to selectively receive and grasp onto one or more needles extending proximally from the needle lumens of the suturing system.

Needle removal devices, systems, and methods

A handheld radiation delivery system is disclosed that includes a two-part delivery module comprising a reusable portion that contains a radioactive source wire and a disposable portion that includes a drive assembly for moving the radioactive source wire between storage and treatment positions. A disposable applicator tip is provided that includes a cannula for receiving the radioactive source wire when in the treatment position and a mechanism for limiting the number of uses of the device. A handheld cable actuator is operatively connected to the disposable portion of the handpiece to impart motion to the source wire.
