Abstract: A detachment system for delivering an embolic coil implant to a treatment site is provided. A pull wire through a lumen of the detachment system that engages a loop wire can include a slack section. The slack section can be one or more bends, a spiral coil, or a stretchable material. The slack section is effective to inhibit premature detachment of the implantable medical device by inhibiting movement of the distal end of the pull wire when the detachment system is traversing a microcatheter.

Abstract: A device includes including an elongated hollow member with a window for receiving tissue in an interior of the hollow member; a rigid member slidably coupled to the hollow member; and an actuation mechanism configured to move the rigid member longitudinally along a longitudinal axis through at least part of the window. When a ligation band is adjacent to the window and the rigid member is moved relative to the hollow member, the rigid member deforms the ligation band from an open position into a closed position around tissue received in the window.

Abstract: A stent device including a stent cover having differing porosity ratio is disclosed. The stent covers the stent body comprising of stent wires and stent cells enclosed by the stent wires. The stent cover differs in porosity ratio for areas covering the stent wires and the areas covering the stent cells. The porosity ratio for areas covering the stent wires may have a higher porosity rate in order to promote endothelialization of the stent device. A bilayer stent cover differing in porosity ratio may be used to cover the stent body, as well as stent cover not covering the entirety of the stent body.

Abstract: A barbed rod device is provided for tissue closure and approximation. The device includes two or more subassemblies. Each subassembly includes a receiver having a central opening and centerline axis, a plurality of barbs extending radially outward from the receiver, and a linking rod extending from the receiver along the centerline axis of the receiver. The linking rod includes a locking end opposite the receiver. The locking end of a first subassembly is configured to engage the receiver of a second subassembly.

Abstract: A soft anchor having a sleeve, being a circular braided suture defining a lumen, and defining a first terminus, having a first terminus opening and a second terminus having a second terminus opening. Also, a deployment suture is engaged to the sleeve by extending into the lumen through a first broach point, then out of the sleeve through the first terminus opening, then into the sleeve through a second broach point, on the bottom-side, and then out of the lumen though a third broach point, then into the lumen through the second terminus opening and out of the suture though a fourth broach point, thereby creating a first lateral trap, between the first broach point and the first terminus opening, a second lateral trap, between the second terminal opening and the fourth broach point, and a central trap, between the second and third broach points.
