Abstract: A method for making a vascular prosthesis having an outer crimped textile graft and an inner polymeric liner includes securing the polymeric liner to valleys of the crimps of the textile graft while leaving the peaks of the textile graft free of the liner. The polymeric liner is impermeable to blood flow. The inner liner may include expanded polytetrafluoroethylene polymer, and the graft may include polyethylene terephthalate yarns.

Abstract: An assembly for an end-to-end anastomosis includes a self-supporting, radially contractible and radially expandable hollow tubular metallic member having opposed open ends. A textile graft is securably disposed over one of the open ends of the hollow tubular member. The other end of the hollow tubular member may be disposed within a bodily lumen for an end-to-end anastomosis. The assembly may further include a suture needle and suture material, where the suture material is securably disposed to a portion of the tubular member.

Abstract: A small diameter vascular prosthesis includes an outer textile graft, an intermediate self-supporting coil or stent and an inner microporous layer. The outer textile graft allows for tissue ingrowth. The inner microporous layer provides blood impermeability without preclotting the prosthesis. The coil or stent provides kink resistance and resistance again collapsing of the outer textile graft and the inner microporous layer.

Abstract: An anastomosis device may include an anchor including a base with an opening and a riser portion securably associated with the base. The base is configured to be disposed within a body lumen. The riser portion includes at least one attachment point with a tubular and hollow graft secured directly to the at least one of attachment point of the riser portion. The at least one attachment point of the riser portion is free of sutures or pins traversing portions of the graft proximal the riser portion. The at least one of attachment point of the riser portion may be in the form a tip of a hook. The anastomosis device may further include at least two additional attachment points for securing the graft to the riser portion.

Abstract: A sealing arrangement for a medical introducer having a distal end for introduction into a patient's blood vessel. The introducer includes a flexible sealing member having an aperture for introduction of a guide wire or other medical device therethrough. A constraining structure, such as a washer, tightly contacts and surrounds the sealing member just proximal to an enlarged diameter flange at the distal end of the sealing member. The inner diameter of the constraining member is less than the outer diameter of the flange providing a constraint on the sealing member and lessening the distortion of the sealing member normally occasioned when a device is pulled outwardly or proximally through the introducer away from the patient. When the constraining structure is a washer, the washer is easily assembled to the introducer by simply being fitted into an annular notch formed just proximal to the distal end of the sealing member.

Abstract: A medical device for controlling the tip of an inner guidewire for advancement of an interventional device throughout the arterial system of a patient. The device includes an elongated housing with a closed rear end and an opposing open end. A traveller is disposed within the elongated housing and slides along the longitudinal axis of the elongated housing. A tubular shaft member that is attached to the proximal end of the traveller extends through the open end of the elongated housing. The proximal end of a guidewire is fixedly attached to the rear end of the elongated housing. The guidewire extends longitudinally through the elongated housing, through the traveller and is contained within the passageway of the tubular shaft member.
