Abstract: Devices and methods for deploying self-cinching surgical clips. A device can access at least two layers of tissue or material from only one side of the tissue or material and puncture through the two layers of tissue or material. The various configurations of clips disclosed herein can be made of a superelastic material such as Nitinol, and have a constrained and a relaxed state, and no sharp edges or tips so as to reduce tissue irritation following deployment. The clip can be disposed within the housing of the delivery device and held in a constrained state until deployment wherein the clip assumes its relaxed state, where the ends of the clip can be brought into close approximation, thereby securing the layers of tissue or material together.

Abstract: Embodiments of valve repair systems, leaflet clip devices, and methods of reducing regurgitation through a native heart valve are disclosed. A valve repair system can include a delivery apparatus and a leaflet clip device that is coupled to the delivery apparatus. The leaflet clip device can comprise an elongated clipping member, and a tensioning mechanism. One or more tensioning members are operatively connected to the tensioning mechanism to transform the clipping member from a delivery configuration to an implantation configuration. The one or more tensioning members can include a first tensioning member having a distal end portion that is connected to a first end portion of the clipping member and a second tensioning member having a distal end portion that is connected to a second end portion of the clipping member.

Abstract: Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

Abstract: An expandable sheath is disclosed herein, which has a first polymeric layer and a braided layer positioned radially outward of the first polymeric layer. The braided layer includes a plurality of filaments braided together. The expandable sheaths further include a resilient elastic layer positioned radially outward of the braided layer. The elastic layer is configured to apply radial force to the braided layer and the first polymeric layer. The expandable sheath further includes a second polymeric layer positioned radially outward of the elastic layer and bonded to the first polymeric layer such that the braided layer and the elastic layer are encapsulated between the first and second polymeric layers. Methods of making and using the devices disclosed herein are also disclosed, as are crimping devices that may be used in methods of making the devices disclosed herein.

Abstract: Methods for the conditioning of bioprosthetic material employ bovine pericardial membrane. A laser directed at the fibrous surface of the membrane and moved relative thereto reduces the thickness of the membrane to a specific uniform thickness and smoothes the surface. The wavelength, power and pulse rate of the laser are selected which will smooth the fibrous surface as well as ablate the surface to the appropriate thickness. Alternatively, a dermatome is used to remove a layer of material from the fibrous surface of the membrane. Thinning may also employ compression. Stepwise compression with cross-linking to stabilize the membrane is used to avoid damaging the membrane through inelastic compression. Rather, the membrane is bound in the elastic compressed state through addition cross-linking. The foregoing several thinning techniques may be employed together to achieve strong thin membranes.

Abstract: A device, system, and method for providing access to, and sealing of, a body organ includes an implant device. An implant device has a main body having an internal access lumen, with a plurality of prongs extending from a distal end of the main body. The main body can include two lumens, one slidable within the other, to form a single continuous lumen with an adjustable length. The main body has an expanded configuration with an expanded diameter, and an unexpanded configuration with an unexpanded diameter. The prongs have a generally straight configuration where they extend distally of the distal end of the main body, and a bent configuration where the prongs bend around so that their tips extend proximally of the distal end of the main body. The device may include a hemostatic barrier to prevent fluid leakage therethrough when the main body is in the unexpanded configuration.
