Abstract: A delivery system for an anastomosis connector, comprising: a body including a handle for applying force; a capsule adapted to interlock with said body and for carrying a connector, wherein said force is transferred by said interlocking to deploy said connector; and an extension, adapted to be connected between said body and said capsule, thereby extending a reach of said delivery system.

Abstract: A vascular attachment device (800) seals an opening between two blood conduit tips, where the device comprises a ring element (752); a plurality of fingers (754) mounted on the ring element (752) and adapted to seal at least a portion of an opening between the two blood conduit lips by compressing at least two lips between at least one finger (754) and the ring element (752); and at least one puller spike (812) adapted for pulling, inside the body, at least one of the lips to a space defined between the finger (754) and the ring element (752).

Abstract: This invention is a hole closure device (100) having at least two blood vessel engaging structures (106), preferably spikes, each comprising a base (102), at least one second, deformable structure (112) coupled to said at least two blood vessel engaging structures (106), having a first deformation state, and a second deformation state; wherein said at least one second deformable structures (106) urges said two blood vessel engaging structures (106) towards each other when going from said deformation state to said second deformation state; wherein said change in deformation state is at least partially mechanically decoupled from each of said blood vessel engaging structures (106).

Abstract: Hole forming apparatus (100) for forming an opening in a blood vessel (106) comprising a penetration head (104) for insertion through a wall of a blood vessel (106). The apparatus (100) has a base section (102) and at least one cutting surface (114) on at least one of the base section (102) or the penetration head (104). The cutting surface (114)is adapted to contact first an intima surface of the blood vessel (106) The apparatus (100) further has a shaft operatively connected to the cutting surface (114) and configured to rotate the cutting surface (114) relative to the blood vessel (106), while the penetration head (104) and the base section (102) are brought together, to effect a removal of a plug tissue section from the blood vessel (106).

Abstract: An anastomotic connector device (102) for mounting a graft (100) in which the connector has spikes (106) defining a periphery around the base ring (104). Also a graft expander (900) having a body (906), a lower diameter tube portion (908) connected by truncated cone (910) and a finger rest (902) and plunger (904).

Abstract: The present invention provides radially-expandable stents that, in various embodiments, provide controllable expansive force profiles. The expansive force profiles can be controlled by varying the unrestrained expanded diameter of the stents, by varying the longitudinal length of the circumferential support sections in the stents, and/or by varying the circumferential width of the struts in the support sections. Also disclosed are methods of deploying the stents.

Abstract: The present invention provides radially-expandable stents that, in various embodiments, may reduce the bending stresses/strains associated with the compressed state of self-expanding stents and/or may prevent longitudinal expansion/contraction of radially expandable stents between the compressed and expanded states. In addition, stents according to the present invention preferably exhibit increased longitudinal flexibility in both the compressed and expanded states. The present invention also includes delivery systems in which threading of the guidewire through the delivery system may be simplified. In addition, the delivery systems according to the present invention may also incorporate a balloon to assist in radially expanding the stent and/or seating of the stent in the lumen during deployment without removing the stent delivery catheter.

Abstract: A graft delivery system (302), having a tubular element for delivering a graft (510) through a bore (320) thereof and having a delivery end (410) and the end being prone to distortion and at least one collar (300) removably encircling the delivery end, which collar prevents the distortion.

Abstract: Stents which are inserted into a body lumen preferably are made of materials which are not radiopaque enough, such as stainless steel 316L. X-ray visualization of a stent enables an accurate positioning of the stent and also a follow-up of its functioning within the patient's body. The radiopaque markers described here are rivets made of a material which is more radiopaque than the stent substance so the location of the stent can be identified. Preferably the stents are heat treated so that atoms from the stent material migrate into the marker material and vice versa.
