International Classification:

A61F 2/06

US Classification:

623 112

Abstract:

A delivery system for an implantable vascular prosthesis is provided for a vascular prosthesis including at least first and second helical sections having alternating directions of rotation that are coupled to one another at apices. The delivery system includes an elongate body, a plurality of retainers and an outer sheath. The plurality of retainers are configured to temporarily retain a plurality of inner wound apices of the vascular prosthesis. The outer sheath is configured to retain the vascular prosthesis in a contracted state on the elongate body.

Abstract:

A perfusion-type intravascular catheter having an outer sheath disposed about the catheter body with a sealing element on the distal end of the sheath to seal off the distal end thereof at a location distal to perfusion ports provided in the wall of the catheter body proximal to an expandable working member such as an inflatable balloon whereby blood can be directed through the proximal perfusion ports into an inner lumen extending through the working member and out of perfusion ports provided into the walls of the catheter distal to the expandable working member to ensure that ischemic conditions do not occur distal to the catheter when the working member is expanded to perform a vascular procedure therein.

US Classification:

623 111

Abstract:

For scaffolds delivered and deployed intravascularly, one or several configurations may be employed for creating a smoother transition from balloon-to-scaffold. For instance, one or more spacers may be positioned in proximity to the scaffold. Alternatively, portions of the inflatable balloon may be configured to provide a smooth transition. In another alternative, the stent edges may be shaped to provide a smooth transition. In yet other variations, any number of different combinations of such features may be employed.
