Abstract: 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.

Abstract: 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 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 connective spines may also be included.

Abstract: This invention is an intraluminal stent (10) made of a zigzag or sinusoidal member defining a successive series of struts (14) connected by apex sections (15), and formed into a series of axially displaced hoop members (12a-12n) wherein at least one of the hoop members has at least one strut (14) connected to a strut (14) of an adjacent hoop. The connected struts (14) may be connected by spot welding, continuous welding, or suturing, for example, or by a bridging member (26) connected to each strut (14), and may be spaced along the length of the stent in a pattern to form a connective spine (16). The number of zigs of the zigzag member in each hoop member (12a-12n) may be varied, as can the zig length (L1). A plurality of connective spines (16) may also be included.
