Abstract
This application is directed to a device comprising a covering attached to the device. A process of making a device with a specific covering attached is also disclosed. The application further discloses a method for the treatment of perforations, fistulas, ruptures, dehiscence and aneurisms in luminal vessels and organs of a subject.
Claims21
A method for occluding an opening in a luminal vessel, comprising:
- placing at said opening a device comprising:
- an expandable stent body comprising a plurality of cells formed by a set of struts, wherein each cell has a center and wherein the stent body is coated with a layer of biodegradable material comprising a biodegradable polymer, wherein at an area close to said stent body's struts the layer of biodegradable material is coated thicker relative to coating moving away from the stent body's struts towards the centers of each cell;
- and
- an electrospun fibrous covering comprising a biodegradable material, wherein the electrospun fibrous covering covers said layer of biodegradable material and said stent body for increased stability during placement, wherein said layer of biodegradable material promotes adherence of the electrospun fibrous covering, wherein fibers within said electrospun fibrous covering interlock and overlap forming shapes comprising angles and rings of varying sizes, wherein the layer of biodegradable material contains the same material as the biodegradable material of the electrospun fibrous covering, and
- wherein the electrospun fibrous covering covers at least a portion of the stent body;
- and
- expanding said stent body to immobilize said device at said opening.

A method for treating a condition in a luminal vessel in a subject, comprising:
- introducing into said subject a device comprising:
- an expandable stent body comprising a plurality of cells formed by a set of struts, wherein each cell has a center and wherein the stent body is coated with a layer of biodegradable material comprising a biodegradable polymer, wherein at an area close to said stent body's struts the layer of biodegradable material is coated thicker relative to coating moving away from the stent body's struts towards the centers of each cell;
- and
- an electrospun fibrous covering comprising a biodegradable material, wherein the electrospun fibrous covering covers said layer of biodegradable material and said stent body for increased stability during placement, wherein said layer of biodegradable material promotes adherence of the electrospun fibrous covering, wherein fibers within said electrospun fibrous covering interlock and overlap forming shapes comprising angles and rings of varying sizes, wherein the layer of biodegradable material contains the same material as the biodegradable material of the electrospun fibrous covering, and wherein the electrospun fibrous covering covers at least a portion of the stent body;
- positioning said device at a treatment site;
- and
- expanding said stent body to immobilize said device at the treatment site.
