An occlusion device (e.g., for treatment of the left atrial appendage) includes a framework and a biocompatible covering disposed over at least a part of the framework. The framework may include a proximal portion, a middle portion, and a distal portion, wherein: the proximal portion includes a first hub that has a fixed first diameter; the middle portion has a second diameter and includes a plurality of beams extending from the first hub to a distal portion, wherein each of the plurality of beams is connected to an adjacent beam by a first circumferentially extending column of strut pairs; and the distal portion has a third diameter. In one or more embodiments, the framework includes improved circumferential strength and minimizes foreshortening.

Occlusion device

A device for occluding a target body lumen, comprises a wire structure defining a wire structure lumen extending therethrough and movable between a reduced diameter insertion configuration and an expanded diameter deployed configuration and a basket structure extending across the wire structure lumen and including therein a cell growth promoting agent to promote cell growth across the wire structure lumen to occlude the target body lumen.

Occlusion stent

In one embodiment of the invention, a stent may be provided comprising a first undulating band having alternating peaks and troughs, a second undulating band having alternating peaks and troughs, a first substantially longitudinal connector extending between the first and second undulating bands and a second very short connector extending between the first and second undulating bands, the first connector substantially longer than the second very short connector.

Flexible and expandable stent

Segmented articulatable stent of open structure comprised of end-connected struts of first and second lengths making up first and second segments with angular interconnects between adjacent first and second segments.

Longitudinally flexible expandable stent

Improved stent configurations exhibiting limited recoil, resistance to compression and improved longitudinal flexibility.

Stent configurations

A generally cylindrical, radially expandable stent may be composed of a plurality of interconnected multibonate cell structures. The cells have three or more enlarged end portions radiating from a common center within the cell. The cells may be of tribonate or higher order multibonate configuration. Stents composed up of a series of generally multibonate cell elements are also disclosed.

Stent cell configurations

A flexible tubular stent including loosely interlocked annular elements without intersections or cross-over points.

Flexible stent

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.

Stent design

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.

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.

Multi-layer stent

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.
