Depth penetration limiters for use with meniscal repair devices which have a built-in, self-stopper feature to prevent the limiter from disengaging from the device housing. The self-stopper feature is a cantilevered flexure on a bottom surface of the limiter that deflects as it is moved through the housing. As the flexure passes the edge of a recess in the housing, the flexure returns to its original shape, trapping the flexure within the recess and preventing further distal movement of the limiter/depth tube. A connection feature on the limiter provides increased pull-off resistance of the depth tube from the limiter.

Depth penetration limiter for a tissue repair device

Tissue repair devices include an advancement assembly comprising a rod portion configured to advance through a needle to expel first and second implants from the needle, a ratchet coupled to a proximal section of the rod portion and configured to advance the rod through the needle by axial and rotational movement, and an advancement member having a linear travel axis including a first bore connected to a second bore. A diameter of the first bore is smaller than a diameter of the second bore such that the first bore and the second bore comprise a stop. The rod portion has mechanical properties optimized to both conform to a needle curvature and provide sufficient compressive strength to expel implants from the devices.

Meniscal repair delivery device

A single-patient-use disposable tool comprises a molded, single-piece body with a curved upper surface having a predetermined bend radius for bending a needle slidably disposed in a sheath. A distal end of the curved surface has a slot for insertion of a tip of a needle, while the proximal end of the curved surface has a guide member for slidably receiving the sheath. Two finger loops or similar ergonomic features allow the user to rotate the bending tool relative to the sheath to bend the needle about the predetermined bend radius. After completing the bend, the tool is removed from the needle and disposed of.

Bending tools and methods of use thereof

Embodiments of the invention include a tissue repair system and related components and associated methods that provide for suturing of tissue using three or more suture anchoring implants, including multiple pairs of connected implants in some embodiments, all of which may be deployed from a single device. Some embodiments achieve this by employing a push mechanism capable of being activated to advance the push mechanism incrementally to discrete positions within the device and deploy implants one at a time from the device.

Tissue repair device and method

Surgical drill guides have modular configurations and are adapted to accommodate a wide range of anatomy. The surgical drill guides are adapted to be removed while leaving a guide wire in its intended location in human bone. The distal end of the drill guide acts as a safety stop for the guide wire by preventing the guide wire from penetrating too far past the far side of the bone.

Surgical drill guide systems and methods of use thereof

Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.

Anchor delivery systems

A knot pushing and suture-cutting device is disclosed including a handle having a multi-positional control and an inner shaft and outer tube extending from the handle. The inner shaft and outer tube both comprise slots and the outer tube is both axially and rotationally moveable relative to the inner shaft, to move the inner shaft and outer tube slots relative to each other. In a first configuration, the inner shaft and outer tube slots are aligned and configured to receive a suture therein. In a second configuration, the slots are configured to lock the suture within a lumen of the inner shaft. In a third configuration a cutting edge on the outer slot is configured to cut the suture.

Side-loading knot cutter

A drill guide system provides a means of improved tunnel placement accuracy by allowing the drill guide to articulate to seat against the bone being drilled. The drill guide includes an articulating drill guide adapter constructed in four parts: a top cap, a thumbscrew, a lock tab, and a spring mechanism. The drill guide adapter is part of an aimer arm which mates with a handle on the proximal end and an aimer guide on the distal end. The drill guide adaptor allows the aimer guide to articulate relative to an irregular mating surface, allowing for increased area contact between the aimer guide template and bone. Examples of the drill guide adaptor also include a means for locking the aimer guide into place relative to the aimer arm.

Surgical drill guide system with articulating guide adaptor

A meniscal repair instrument includes an articulating mechanism configured to move a needle on the tip in a controlled arc. Multiple directions of motion are provided in order to facilitate the deployment of suture anchors. In one aspect, the articulating mechanism includes a series of movable members that are coupled together by two wires that are provided with a push/pull force via a control mechanism.

Articulated meniscal repair instrument

A tissue repair device including a handle, an elongated needle body defining an axial bore extending from the handle, first and second implants connected by a suture and disposed at least partially within the axial bore of the needle. A ratchet assembly includes a pusher member that incrementally advances through the needle body to urge the first and second implants therefrom in a predefined sequence, a proximally-biased rotatable ratchet coupled to the pusher member, and an axially translatable drive mechanism configured to provide axial and rotational driving forces causing the ratchet to alternately engage and disengage from successively more distal teeth of a toothed surface within the handle. One or more implant retention features impeded undesired expulsion of implants from the needle.

Tissue repair device

Retro guidewire reamers include a drill having a tubular shaft configured to be disposed over a guidewire and at least one cutting member movably disposed adjacent the distal end of the shaft. A slide actuator is moveably coupled to the shaft and to an actuator wire slidable along the shaft. The actuator wire is operative to move the at least one cutting member between a closed position and a deployed position when the slide actuator is moved along the shaft. The retro guidewire reamers include mechanisms to protect the mechanical joint between the actuator wire and the slide actuator which prevent the actuator wire from disengaging from the slide actuator when the cutting member is obstructed by a guidewire.
