  • Patent number: 8758397
    Abstract: A vascular closure device comprising a retrievable sheath-delivered contractible, clip device with structural radial or terminal members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure clips, this device is delivered on the outside rather than the inside of sheath. Closure of the tissue opening can be effected by the feet of the clip engaging the puncture, aperture, or wound edges and memory characteristics of the device cause a contraction of the members, bringing the members into apposition and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

  • Patent number: 8728119
    Abstract: A generally U-shaped surgical staple comprises a base 10 and a pair of generally “L”-shaped legs 12 extending substantially perpendicularly from opposite ends of the base respectively. The legs 12 in use of the staple are bent through approximately 90° relative to the base. To effect a greater compression of the stapled tissue the legs include a penetrative portion 16 adjacent the tip and a compressive structure 30 which, due to its increased height relative to that of the penetrative portion, spreads the compressive forces of the staple further along the length of the incision being closed. The compressive portion also provides a depth stop to avoid the tip penetrating too deeply into the tissue in which it is deployed.

  • Patent number: 8715719
    Abstract: A method of preparing a stable chitosan hemostatic implant including preparing a lyophilizable solution of chitosan polymers and freezing the solution to obtain a frozen chitosan composition. The method further includes placing the frozen chitosan composition under vacuum so as to substantially dry the chitosan composition and curing the dried chitosan composition by first exposing it to a relative humidity and then curing the dried chitosan composition under heat so as to crosslink the chitosan polymers.

  • Patent number: 8685047
    Abstract: A scaffold is provided for managing access through tissue. The scaffold can support the tissue during medical procedures. The scaffold is placed around or proximate an opening in tissue. The scaffold can expand when medical devices are introduced through the scaffold and through the opening and retract when the medical devices are removed. When the medical devices are removed, the scaffold closes automatically to substantially close the opening.

  • Publication number: 20130253547
    Abstract: The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

  • Patent number: 8409273
    Abstract: Devices, systems, methods and kits are provided for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by a multi-catheter guiding system which is positioned in a desired configuration, generally directed toward the target tissue. Interventional devices may then be passed through the guiding system to the target tissue. Depending on the location of the target tissue and the desired angle of approach, the guiding system may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. The multi-catheter guiding system of the present invention comprises an outer guiding catheter and a coaxially positioned inner guiding catheter, each of which independently form curvatures so that together the curves properly direct the interventional device.
