A helicoil interference fixation system comprising: a helicoil comprising a helical body comprising a plurality of turns separated by spaces therebetween, the helical body terminating in a proximal end and a distal end, and at least one internal strut extending between at least two turns of the helical body; and an inserter for turning the helicoil, the inserter comprising at least one groove for receiving the at least one strut; the helicoil being mounted on the inserter such that the at least one strut of the helicoil is mounted in the at least one groove of the inserter, such that rotation of the inserter causes rotation of the helicoil.

Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.

A ringless web is configured to repair heart valve function in patients suffering from degenerative mitral valve regurgitation (DMR) or functional mitral valve regurgitation (FMR). In accordance with various embodiments, a ringless web can be anchored at one or more locations below the valve plane in the ventricle, such as at a papillary muscle, and one or more locations above the valve plane, such as in the valve annulus. A tensioning mechanism connecting the ringless web to one or more of the anchors can be used to adjust a tension of the web such that web restrains the leaflet to prevent prolapse by restricting leaflet motion to the coaptation zone and/or promotes natural coaptation of the valve leaflets.

A method of repairing a defective heart valve involves positioning first and second support rings of an annuloplasty device in a first configuration on opposite sides of native heart valve leaflets and activating a contracted state of the annuloplasty device so that a first pitch distance between the first and second support rings in the first configuration is reduced to a second pitch distance that is shorter than the first pitch distance to move the first and second support rings toward each other to pinch the native heart valve leaflets.

Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.

A delivery device for an annuloplasty implant is disclosed comprising an outer sheath, a delivery wire being movable within said sheath in a longitudinal direction thereof, a holder being releasably connectable to said implant, said holder being pivotably connected to a distal portion of said delivery wire, wherein said holder is folded inside said outer sheath in a delivery configuration, and wherein said holder is foldable from said delivery configuration to an expanded deployed configuration outside said outer sheath. A system comprising such delivery device and an annuloplasty implant, and a method of delivering such implant is also disclosed.

A small diameter vascular prosthesis includes an outer textile graft, an intermediate self-supporting coil or stent and an inner microporous layer. The outer textile graft allows for tissue ingrowth. The inner microporous layer provides blood impermeability without preclotting the prosthesis. The coil or stent provides kink resistance and resistance again collapsing of the outer textile graft and the inner microporous layer.

A stent configured to change in length while maintaining a constant inner diameter is disclosed. The stent includes an elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with rungs extending circumferentially between adjacent twisted knit stitches, wherein each twisted knit stitch is interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The tubular member is configured to be stretched from a first length to a second length while in a radially expanded configuration without substantially changing the inner and/or outer diameter of the tubular member.

A void occlusion device that includes a scaffold defining a plurality of voids and a reinforcement member is described. The scaffold is configured to permit the infiltration of human tissue into the plurality of voids. The reinforcement member extends through at least a portion of the scaffold and is configured to resist compressive forces exerted on the scaffold. Also described are embodiments where the void occlusion device is biocompatible, bioresorbable, elastic, and suitable for radio imaging.

An anchor for a prosthetic heart valve includes a core, a first cover layer, and a second cover layer. The core includes a plurality of helical turns. One or more outflow turns of the plurality of helical turns has a diameter configured to be disposed on an outflow side of a native valve, and one or more inflow turns of the plurality of helical turns has a diameter configured to be disposed on an inflow side of a native valve. The first cover layer is disposed over and contacts the helical core, and the first cover layer includes a first material. The second cover layer is disposed over and contacts the first cover layer, and the second cover layer includes a second material, which is different than the first material.
