An intraluminal stent made of a zig-zag or sinusoidal member defining a successive series of struts connected by apex sections and formed into a series of axially displaced hoop members wherein at least one of the hoop members has at least 5 one strut connected to a strut of an adjacent hoop. The connected struts may be connected by spot welding, continuous welding, or suturing, for example, or by a bridging member connected to each strut, and may be spaced along the length of the stent in a pattern to form a connective spine. The number of zigs of the zig-zag member in each hoop member may be varied, as can the zig length. A plurality of 10 connective spines may also be included.

Intraluminal stent

A method and apparatus for forming a covered endoprosthesis employs a conformed polymeric coating about an expandable stent. The expandable stent has an open tubular construction. A first polymeric liner is positioned about an inner surface of the tubular stent and a second polymeric liner is positioned about an outer surface of the tubular stent. The first and second polymeric liners are conformed to the tubular stent and laminated together through the open construction of the stent at a location coextensive with the inner surface of the tubular stent.

Conformal laminate stent device

A tubular intraluminal prosthesis includes a PTFE or ePTFE tubular structure such as a graft, and a tubular diametrically deformable stent circumferentially surrounding the tubular structure. The diametrically deformable stent includes a polymeric coating which allows for attachment to the tubular graft structure and enhances the biocompatibility and integrity of the composite prosthesis.

Polymer coated stent

A process for impregnating a porous material with a cross-linkable composition is disclosed. The degree of impregnation and placement of the cross-linkable composition within the pores of the porous material can be controlled very precisely through the use of a pressure differential. The pressure differential is effected through a nonreactive gas, a vacuum, or a combination thereof. Medical devices produced using such a method are also disclosed.

Process for impregnating a porous material with a cross-linkable composition

This invention is an intraluminal stent ( ) made of a zigzag or sinusoidal member defining a successive series of struts ( ) connected by apex sections ( ), and formed into a series of axially displaced hoop members ( ) wherein at least one of the hoop members has at least one strut ( ) connected to a strut ( ) of an adjacent hoop. The connected struts ( ) may be connected by spot welding, continuous welding, or suturing, for example, or by a bridging member ( ) connected to each strut ( ), and may be spaced along the length of the stent in a pattern to form a connective spine ( ). The number of zigs of the zigzag member in each hoop member ( ) may be varied, as can the zig length (L ). A plurality of connective spines ( ) may also be included.
