Abstract: Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.

Abstract: The invention relates to a hollow rasp for preparing a tubular bone in which a post-shaped endoprosthesis is inserted. A manipulating instrument can be proximally coupled to the rasp. The rasp comprises a metal grid network and a plurality of metal rasp elements. The metal rasp elements are studded at least at junctions of the metal grid network and are an integral part of a material forming the grid network.

Abstract: A stent delivery system comprises a catheter having a distal end and a proximal end, and a self expanding stent device having a compressed state and an expanded state and being positioned along the catheter and close to the distal end thereof. The stent delivery system further comprises a capsule enclosing the self-expanding stent device in its compressed state along substantially the whole length thereof. The capsule has an open distal end and a proximal end fixed to the catheter. Further, the capsule has at least one perforation extending longitudinally of said capsule from the distal end substantially to the proximal end thereof. The stent delivery system also comprises a balloon positioned within the capsule so as to break the capsule along said at least one perforation when inflated, whereby the stent device may expand to its expanded state, Thereafter the catheter with the broken capsule may be withdrawn from a duct in which the catheter has been introduced to a desired position.

Abstract: A biocompatible form and a method for fabricating the implant are provided. The biocompatible form may be used to support bone graft material such as that used to reconstruct missing bone in a patient's oral cavity. The implant is fabricated from a biocompatible mesh, which may be made of titanium, a titanium alloy or fiber and is permanently implantable in the patient's oral cavity. The biocompatible form has an anatomical configuration which includes one or more portions conforming substantially to various alveolar bone contours which may include predetermined, human interproximal bone contours, root prominence bone contours and mylohyoid ridge bone contours. The biocompatible form may include a palatal section. The biocompatible form may also include one or more apertures for receiving a corresponding number of dental prostheses therethrough.

Abstract: An endoprosthesis, such as a stent, having a layer that can enhance the biocompatibility of the endoprosthesis, and methods of making the endoprosthesis are disclosed.

Abstract: A stent radially expandable from a radially contracted introduction state into a radially expanded position state, in which the final shape of the stent can be controlled by varying the amount and places energy is delivered onto the interior surfaces of the tubes from which the stent is fabricated, and means to seal the opening into the aneurysm, thereby causing the blood therein to clot and preventing the aneurysm from growing or rupturing.

Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly within the capsular bag and laying against the posterior capsule. The periphery of the first optic contains a pair of generally T-shaped haptics having a generally rectangular slot within the top portion of the “T”. The second optic is located anteriorly to the first optic outside of the capsular bag and is of a positive power. The peripheral edge of the second optic contains a pair of encircling haptics having a notched tab sized and shape to fit within the slots in the haptics on the first optic to lock the second optic onto the first optic. Hinge structures on the encircling haptics allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle.

Abstract: An implantable, biocompatible, osteogenic bone graft comprises at least one zone of impermeability to soft tissue ingrowth which is integral with the bone graft. Application of the bone graft to a bone repair site leads to selective rapid new bone ingrowth and inhibits or prevents soft tissue, e.g., gingival, epithelial, connective and/or muscle tissue, ingrowth in those areas adjacent to the zone(s) of impermeability to soft tissue ingrowth. The bone graft can be employed in a wide variety of bone repair procedures.

Abstract: The invention provides arteriovenous grafts and methods for implanting the same. In one aspect of the invention, there are provided arteriovenous grafts that have a stepped down venous end. In another aspect, the invention provides arteriovenous grafts having cuffs for attachment to a target vein. The invention also provides methods for implanting arteriovenous grafts that include inserting the venous end of a graft into the target vein for positioning downstream of the venotomy site.

Abstract: A surgical implant system includes an implant body and an osseostimulative surface applied to, or used with, the implant body, the surface including a calcium sulfate (CS) compound which is a member selected from the group consisting of CS dihydrate, CS hemihydrate, anhydrous CS, and mixtures thereof. The performance and rate of resorption of the osseostimulative surface may be improved or modified through the use of a stabilizing component, a viscosity modifier, a pH modifier, or a cell growth inductive microgeometry. The system is also definable in terms of an in situ system of bone augmentation in which a bio-resorbable CS matrix, in various physical forms, from a kit is disposed about the surgical implant positioned within an osseotomy site.
