Abstract

Materials and methods for reducing or preventing bleeding and associated side effects during and after percutaneous medical procedures.

Claims

1. An article comprising:

an elongate member having an exterior surface and an interior lumen through which surgical implements can be placed when said elongate member is placed in a wall of an internal organ;

a hemostatic material in contact with at least a portion of said exterior surface;

a covering that surrounds said hemostatic material and is adapted to move slidably over said elongate member;

said exterior surface of said elongate member having a plurality of channels for retaining hemostatic material;

said exterior surface being inflatable to apply pressure along the interior of said wall of said internal organ at the sight of hemostatic material retention after said covering is slidably removed; and

said elongate member configured to achieve hemostasis by the simultaneous application of said hemostatic material and said pressure exerted by said exterior surface of said elongate member while surgery on said bodily organ is performed.

2. The article of claim 1, wherein said channels are V-shaped in cross-section and are configured to retain said hemostatic material and to facilitate localized placement of said hemostatic material within a percutaneous tract of a kidney.

3. The article of claim 1, wherein said channels are semi-circular in cross-section and are configured to retain said hemostatic material and to facilitate localized placement of said hemostatic material within a percutaneous tract of a kidney.

4. The article of claim 1, wherein said channels are rectangular in cross-section and are configured to retain said hemostatic material and to facilitate localized placement of said hemostatic material within a percutaneous tract of a kidney.

5. An article comprising:

an inflatable elongate member having an exterior surface and an interior lumen through which surgical implements can be placed when said elongate member is placed in a wall of kidney;

hemostatic material on said exterior surface;

a plastic film surrounding said hemostatic material configured to be broken and removed for deployment of said hemostatic material along a course of said percutaneous tract; and

said exterior surface of said elongate member configured to apply pressure along the percutaneous tract of said kidney upon inflation of said elongate member;

said exterior surface configured to retain said hemostatic material at said location of applied pressure to achieve hemostasis after said plastic film is removed and while surgery is performed on said kidney using said surgical instruments.

6. The article of claim 5, wherein said elongate member is configured to achieve hemostasis in said wall of said kidney prior to said elongate member being removed from said wall of said kidney.

7. The article of claim 5, wherein said hemostatic material is configured to remain on the portion of said exterior surface that applies pressure to said internal organ while hemostasis is achieved.

8. The article of claim 5, further comprising a driver having an interior lumen through which surgical implements can be placed, said interior lumen having a diameter of 20 to 26 French.

9. The article of claim 5, wherein said plastic film is a heat sealed plastic with perforations near a distal end of said elongate member to facilitate removal of said plastic film.

10. The article of claim 5, wherein said article is configured to achieve hemostasis at said interior wall of said kidney while surgical instruments for performing percutaneous instruments remain in said wall of said kidney.

11. The article of claim 5, wherein said elongate member and hemostatic material are configured to allow the hemostatic material to maintain contact with and achieve hemostasis at said interior wall of said kidney after said covering is removed.

12. The article of claim 5 further comprising at least one channel on an exterior surface of said elongate member for retaining said hemostatic material and facilitating localized placement of said hemostatic material within said percutaneous tract of said kidney.
