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.

A loading unit includes a staple cartridge assembly, an anvil assembly, and an anvil hook assembly. The anvil assembly has an opening defined therethrough, and the anvil hook assembly includes an anvil hook disposed within the opening of the anvil assembly and a pivot pin extending through the anvil hook and the anvil assembly. The anvil hook is pivotable with respect to the anvil assembly about the pivot pin between a loading position and a loaded position. The loading unit may further include a surgical buttress assembly including a cartridge buttress releasably attached to the staple cartridge assembly, an anvil buttress releasably attachable to the anvil assembly by the anvil hook, and a connecting member interconnecting the cartridge and anvil buttresses.

A loading unit includes a shell assembly, a lock collar, and a release collar. The shell assembly has a coupling ring that defines a lock slot and a proximal opening configured to receive a distal end portion of a surgical instrument. The lock collar is disposed about the coupling ring and has a radially extending lock that is configured to be received within the lock slot. The lock collar is transitionable between a locked configuration in which the lock is positioned within the lock slot and an unlocked configuration in which the lock is lifted from within the lock slot. The release collar is disposed about the coupling ring proximal of the lock collar and is transitionable between an unactuated position and an actuated position. The release collar transitioning the lock collar to the unlocked configuration as the release collar is translated from the unactutated position towards the actuated position.

An anchor construct having an anchor having a length of suture material passing therethrough, the suture material having a loop strand terminating at a first end and a post strand terminating at a second end, a splice loop formed by first end, a sliding construct formed by the first end and the second end, wherein the sliding construct is configured to adjust the relative position of the splice loop and the anchor. The anchor construct can be deployed by passing the first end through a first body and through the splice, creating a locking loop of a first size around the first body, implanting the anchor into a bone hole, pulling the post strand to decrease the perimeter of the positioning loop to a second size smaller than the first size, and pulling the loop strand to decrease the perimeter of the locking loop to a smaller second size.

The present disclosure includes a suturing device including: a fixed arm having a fixed jaw including a first grasping slot configured to receive a needle; a movable arm coupled to a movable jaw including a second grasping slot configured to receive the needle, the movable arm configured to pivot relative to the fixed arm to pivot the movable jaw relative to the fixed jaw until the needle is received in the first grasping slot and the second grasping slot; and a needle transfer mechanism configured to grasp the needle in the first grasping slot or the second grasping slot. In some aspects, the suturing device includes a safety member configured to control when the movable arm moves. The present disclosure includes a loading apparatus including a loading slot configured to receive a fixed jaw and a slider configured to move the needle towards into the fixed jaw.

A suturing device includes a clamshell body having a first side coupled to a second side by a hinge at a hinge end. The first side and the second side each have a cantilevered end opposite the hinge end. The clamshell body is configured to actuate between an open position and a closed position. A suture retainer is positioned within the claim shell body and is configured to receive a suture. An opening is formed in a wall of the of the second side of the clamshell body.

A device for occluding a vasculature of a patient including a micrograft having an absorbent polymeric structure with a lumen of transporting blood. The micrograft has a series of peaks and valleys formed by crimping. The occluding device is sufficiently small and flexible to be tracked on a guidewire and/or pushed through a microcatheter to a site within the vasculature of the patient. Delivery systems for delivering the micrografts are also disclosed.

A device is described. The device includes a suture guide and a tissue retracting surface to enable accurate and safe delivery of sutures through tissue.

In various embodiments, a tissue thickness compensator can comprise one or more capsules and/or pockets comprising at least one medicament therein. In at least one embodiment, staples can be fired through the tissue thickness compensator to rupture the capsules. In certain embodiments, a firing member, or knife, can be advanced through the tissue thickness compensator to rupture the capsules.

A device for loading a trocar assembly with an adapter assembly of a surgical stapling instrument and a method of confirming that the trocar assembly is properly secured to the adapter assembly are provided. The device includes a base member and an engagement arm secured to the base member. The base member defines a longitudinal passage for receiving a trocar assembly and includes a proximal end surface. The engagement arm is configured to releasably secure a trocar assembly within the base member. The engagement arm includes a proximal end surface. The proximal end surface of the base member is configured to engage a distal end surface of a trocar housing of the trocar assembly when the trocar assembly is not properly secured within the adapter assembly.
