Abstract
Example medical stents are disclosed. An example stent includes a tubular framework including an inner surface, an outer surface and a lumen extending therethrough. Additionally, the stent includes a tissue ingrowth scaffold extending along a portion of the outer surface of the tubular framework, wherein the tissue ingrowth scaffold is spaced radially away from the outer surface of the tubular framework to define an expansion cavity therebetween and wherein the tissue ingrowth scaffold permits tissue ingrowth along a portion thereof. Further, the stent includes an expandable member positioned within at least a portion of the expansion cavity.
Claims20
A stent comprising:
- a tubular framework including an inner surface, an outer surface, and a lumen extending therethrough;
- a tissue ingrowth scaffold extending along a first portion of the outer surface of the tubular framework, wherein the tissue ingrowth scaffold is spaced radially outward away from the outer surface of the tubular framework to define an expansion cavity therebetween, and wherein the tissue ingrowth scaffold permits tissue ingrowth therein;
- and
- an expandable member positioned within at least a portion of the expansion cavity, the expandable member being separate from the tissue ingrowth scaffold and is non-continuous with the tissue ingrowth scaffold.
A stent, comprising:
- a tubular framework having a first end and a second end opposite the first end, the tubular framework including an inner surface, an outer surface and a lumen extending therethrough;
- a tissue ingrowth scaffold extending along a portion of the outer surface of the tubular framework adjacent the first end, wherein the tissue ingrowth scaffold is spaced radially away from the outer surface of the tubular framework to define an expansion cavity therebetween, and wherein the tissue ingrowth scaffold permits tissue ingrowth along a portion thereof;
- and
- an expandable member positioned within at least a portion of the expansion cavity, the expandable member configured to radially expand from a first nominal state to an expanded state, wherein the expandable member is separate from the tissue ingrowth scaffold and is non-continuous with the tissue ingrowth scaffold, wherein the expandable member is configured to exert a radially outward force upon the tissue ingrowth scaffold in the expanded state to cause tissue ingrowth within the tissue ingrowth scaffold to recede.
A stent comprising:
- a tubular framework including an inner surface, an outer surface, and a lumen extending therethrough;
- a tissue ingrowth scaffold extending circumferentially around the outer surface of the tubular framework, wherein the tissue ingrowth scaffold is spaced radially outward away from the outer surface of the tubular framework to define an expansion cavity therebetween, and wherein the tissue ingrowth scaffold includes a wire mesh having one or more apertures configured to permit tissue ingrowth therethrough;
- and
- an expandable member positioned within at least a portion of the expansion cavity, the expandable member being separate from the tissue ingrowth scaffold and is non-continuous with the tissue ingrowth scaffold.
