Abstract

An endoluminal medical device includes a cannula, the cannula having a proximal end and a distal end; an abrasion member having a series of struts interconnected by a series of bent segments forming a plurality of prongs attached to the cannula, the abrasion member having a first section and a second section; where the prongs of the first section of the abrasion member extend radially outward from the cannula.

First claim

The invention claimed is:

1. A method of introducing an abrasion to the urothelium layer of the ureter, comprising
providing an endoluminal medical device, the endoluminal device comprising
a tubular housing having a proximal end, a distal end, and a lumen longitudinally disposed therethrough;
at least one abrasion member comprising a series of struts interconnected by a series of bent segments forming a plurality of prongs attached to the tubular housing, the abrasion member having a first section and a second section;
where the prongs of the first section of the abrasion member extend radially outward from the housing

introducing the endoluminal device into the ureter; and
abrading the urothelium layer of the ureter with the endoluminal device.

2. The method of claim 1 , wherein the prongs of the first section of the abrasion members have a star shaped configuration.

3. The method of claim 1 , wherein the abrasion member comprises a shape-memory material.

4. The method of claim 1 , wherein the bent segments of the abrasion member have a circular configuration.

5. The method of claim 1 , wherein the prongs of the second section of the abrasion member are disposed on the distal end of the tubular housing.

6. The method of claim 1 , further comprising introducing a scope into the ureter prior to introducing the endoluminal device into the ureter.

7. The method of claim 1 , further comprising reciprocally translating the abrasion member through the ureter in both the proximal and distal direction.
