Assignee:

SciMed Life Systems, Inc. - Maple Grove MN

International Classification:

A61F 206

US Classification:

623 115

Abstract:

A stent comprises at least one band of interconnected cells selected from the group consisting of S-shaped cells and mirror image S-shaped cells. Each cell has a top end and a bottom end. The top end of each cell is attached to the bottom end of an adjacent cell in the band. Adjacent bands may abut one another or may be joined by connecting members.

International Classification:

A61F029/00

US Classification:

623 115

Abstract:

In one embodiment of the invention, a stent may be provided comprising a first undulating band comprising a series of alternating first peaks and first troughs and a second undulating band comprising a series of alternating second peaks and second troughs. The first undulating band has a first wavelength and a first amplitude and the second undulating band has a second wavelength and a second amplitude where the second amplitude is different from the first amplitude and the second wavelength is different from the first wavelength. A plurality of longitudinally oriented first connectors extend between the first peaks and second peaks.

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61F 2/06

US Classification:

623 115

Abstract:

An intraluminal medical device having a flowpath therethrough, the device including a plurality of substantially cylindrical serpentine shaped segments which define a generally tubular body, each serpentine segment having a plurality of struts interconnected by alternating end portions, segments which are adjacent one another connected one to the other. The medical device has a pre-crimped diameter and crimped diameter and is constructed and arranged such that as the cylindrical shaped segments are crimped from the pre-crimped diameter to the crimped diameter at least some of the end portions project into the flowpath.

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61F 2/06

US Classification:

623 115, 606196

Abstract:

A stent may be formed having a reduced state and an expanded state. The stent having a longitudinal axis therethrough. The stent comprises at least one serpentine segment having a proximal end and a distal end. The serpentine segment comprises a plurality of peaks and troughs, wherein the peaks are disposed at the distal end of the segment and the troughs are disposed at the proximal end of the segment. The peaks include first peaks and second peaks arranged in a regular alternating pattern about the longitudinal axis. In the reduced state the first peaks disposed at a first distance from the longitudinal axis of the stent and the second peaks disposed at a second distance from the longitudinal axis of the stent. The second distance is less than the first distance. The first peaks defining a substantially cylindrical outer surface of the segment.
