Knotless suture anchor
A suture anchor comprises a tubular body having an axial bore therethrough and having one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole, such as threads. A lateral port passes through the body from the bore to the exterior surface and is formed of a slot entering the body from its proximal end. A length of suture for attaching soft tissue to bone passes down along the exterior surface over the one or more purchase enhancements, over a distal end of the body, up into the bore through and then back out of the bore and up along the exterior surface over the one or more purchase enhancements.
Threaded knotless anchor
A knotless suture anchor assembly for engaging a bone tunnel and holding suture therein to knotlessly secure said suture to soft tissue including an elongated generally cylindrical hollow outer member having an axial lumen, an outer surface with projections for engaging the wall of the bone tunnel, a distal end and a proximal end; and an elongated, generally cylindrical inner member having an axis, a proximal end and a distal end, the distal end having a transverse passage for receiving suture therethrough, the transverse passage having a proximal and distal end and adapted to receive a plurality of sutures in said eyelet, the inner member adapted to move coaxially relative to the outer member between a distal, suture-unlocked position and a proximal, suture-locked position.
Suture anchor
Suture anchors are disclosed having suture locking features able to lock multiple suture ends extending from a body tissue, such as from a bone tunnel, with a single device.
Deployment instrument for closure device for percutaneously sealing punctures
A deployment instrument for deploying a closure device for sealing a percutaneous puncture in a wall of a body passageway, the deployment instrument including a carrier assembly, wherein the carrier assembly is configured to hold the closure device in a pre-deployment state, and a tensioner assembly, wherein the filament is fixedly attached to the tensioner assembly, wherein the deployment instrument is configured to increase the tension in the filament upon linear movement of the deployment instrument away from the wall of the body passageway when the closure device is anchored to the wall via the anchor such that the tension is gradually increased as the deployment instrument is moved between a first linear distance and a second linear distance greater than the first linear distance from the wall of the body passageway.
Meniscal repair devices, systems, and methods
Meniscal repair devices, systems, and methods are provided.
Retractable tether in apical pad
An epicardial anchor system comprising a tether attachment member defining a portion of a tether passageway configured to receive a portion of a tether extending from a heart valve, a base having a rim defining a void along a circumference of the rim, and a tether capture device adjacent the tether attachment member and hingedly attached to the epicardial anchor, the tether capture device including an opening configured to receive the portion of the tether therethrough and a slot configured to capture the portion of the tether extending through the opening, and an actuation mechanism configured to flip the tether capture device from an unactuated condition to an actuated condition, wherein in the unactuated condition, the tether capture device is spaced from the void defined by the rim, and in the actuated condition, a first portion of the tether capture device is positioned within the void defined by the rim.
MENISCAL REPAIR DEVICES, SYSTEMS, AND METHODS
Meniscal repair devices, systems, and methods are provided.
SLEEVE FOR SOFT TISSUE REPAIR
A sleeve for soft tissue repair includes a cylindrical tube formed of at least one biocompatible material, and a suture tethered to one end of the cylindrical tube. The cylindrical tube is configured to be fitted over a soft tissue. The cylindrical tube is configured to reversibly and repeatedly deform from a relaxed state to a stretched state in which the cylindrical tube contracts in a radial direction and expands in a longitudinal direction to secure the soft tissue within the cylindrical tube.
Knotless suture anchor with unthreaded nose
A suture anchor has a tubular body having an axial bore therethrough with one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole. These are preferably screw threads. A distal nose of the suture body has a smooth exterior surface. A length of suture passes down along the exterior surface over the purchase enhancements, over the distal nose, and up into the bore. The smooth exterior surface of the distal nose allows tension of the suture to be held by the engagement of the nose within the bone hole thus making it easier to obtain proper tension as the remaining portion is engaged into the bone hole to provide final fixation.
Anchor driver with suture clutch
A suture anchor driver has an elongated shaft, a handle at a proximal end of the shaft an anchor engagement at a distal end of the shaft and a clutch between the handle and the shaft. The clutch includes a slot for frictionally engaging a suture an engagement with the shaft and an engagement with the handle. The engagement with the shaft and the engagement with the handle are located with respect to one another such that driving torque applied to the handle urges open the slot to release its frictional engagement of the suture.
