Abstract: An intravascular implant and methods of using the implant within the vasculature of the body, for example near a vascular aneurysm, are disclosed. The method of attaching a second implant, such as a vascular graft, to the intravascular implant is also disclosed. The implant can be made from an anchor, a connector and a seal.

Abstract: Tissue approximation devices for the minimally invasive approximation of muscle or fascia, such as approximation of the rectus muscles in the abdomen (abdominoplasty), or hernia repair and other such applications using minimally invasive methods to access and perform the procedures thereby reducing or eliminating visible scars.

Abstract: Veins are removed using a pull catheter introduced over a guidewire which extends between first and second percutaneous access points. Optionally, a side branch management tool including an excision device and/or a viewing scope can be advanced over the same guidewire in the direction opposite to that of the pull catheter. In that way, as the pull catheter inverts the vein being removed, side branches can be selectively viewed and/or severed using the side branch management tool. Arteriovenous fistulas are formed by inverting a length of a vein, mobilizing the inverted length relocating the mobilized end of the vein, and connecting the mobilized end to an artery.

Abstract: A catheter assembly for performing transmyocardial revascularization through the coronary arteries or veins, and a method of using this assembly for creating TMR channels through the myocardium coronary artery shunts through the myocardium and a device and method for injecting therapeutic agents into TMR channels interoperatively, together with a number of therapeutic agents.

Abstract: Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of through holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.

Abstract: An adjustable surgical valve has a sealing body with an axial passage extending through it, a toroidal body axially aligned with the sealing body, and a device that selectively changes the relative axial positions of the sealing body and the toroidal body. The sealing body and the toroidal body have mating surfaces which radially compress the axial passage of the sealing body when the relative axial positions of the sealing body and the toroidal body are changed. This causes the axial passage to seal with an instrument inserted into it, or to seal with itself if no instrument is inserted. Alternatively, or additionally, the sealing body may include a braided sleeve coaxial with the axial passage and extending from the sealing body, and a device that selectively changes the relative axial positions of the sealing body and the extended part of the braided sleeve to elongate the braided sleeve. This causes the braided sleeve to contract radially, which compresses the axial passage of the sealing body radially.
