Abstract
An expandable frame movable between a collapsed configuration and an expanded configuration includes at least one first member. The at least one first member includes a plurality of substantially parallel first struts and a plurality of second struts. Each second strut is coupled between adjacent first struts and is substantially perpendicular to adjacent first struts with the frame in the collapsed configuration defining a plurality of open cells to facilitate expansion of the frame.
Claims27
An expandable frame comprising:
- at least one first member comprising a plurality of substantially parallel first struts and a plurality of second struts, each second strut of said plurality of second struts coupled between adjacent first struts of said plurality of first struts and substantially perpendicular to said adjacent first struts with said frame in a collapsed configuration defining a plurality of open cells to facilitate expansion of said frame, said frame movable between the collapsed configuration and an expanded configuration.
An expandable frame comprising:
- a first member comprising a plurality of substantially parallel first struts and a plurality of substantially parallel second struts with said frame in a collapsed configuration, each second strut of said plurality of second struts coupled between adjacent first struts of said plurality of first struts defining a plurality of open cells to facilitate expansion of said frame towards an expanded configuration;
- and
- at least one second member coupled to said first member, said at least one second member comprising a plurality of third struts, each third strut of said plurality of third struts coupled to adjacent third struts at an acute angle with said frame in the collapsed configuration.
A stent comprising:
- an expandable frame comprising:
- a first member comprising a plurality of substantially parallel first struts and a plurality of substantially parallel second struts with said frame in a collapsed configuration, each second strut of said plurality of second struts coupled between adjacent first struts of said plurality of first struts defining a plurality of open cells to facilitate expansion of said frame towards an expanded configuration;
- and
- at least one second member coupled between a first point on said first member and a second point on said first member.
An expandable frame comprising:
- a first member comprising a plurality of first struts, each first strut of said plurality of first struts coupled to adjacent first struts at an acute angle with said frame in a collapsed configuration and defining a plurality of open cells to facilitate expansion of said frame towards an expanded configuration;
- and
- at least one second member coupled to said first member, said at least one second member comprising a plurality of second struts, each second strut of said plurality of second struts coupled to adjacent second struts at an acute angle with said frame in the collapsed configuration.
A stent comprising a first segment having a first expansion ratio, and a second segment having a second expansion ratio, at least one of said first segment and said second segment radially expandable to form an opening at least partially defined within a body wall of said stent.
