Appl. No.:

11/640449

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

The invention describes an apparatus and method of use for anchoring two or more body tissue layers to one another. The apparatus includes a plurality of individual anchor segments that are placeable within a body cavity. The segments may assume a first relaxed state wherein the segments are movable relative to each other and alignable along an initial longitudinal axis for initial placement of the apparatus through the body tissue layers. Once placed within the body cavity, the anchor segments are manipulated into a second rigid state with an actuator wherein the segments assume a rigid configuration at a transverse angle relative to the initial longitudinal axis.

Abstract:

A modular intraluminal stent graft. The intraluminal stent graft is bifurcated having a primary section and a secondary section extending therefrom. The primary section tapers from a larger diameter at an upstream end to a smaller diameter at a downstream end. The downstream end of the primary section has a pair of independent openings each having an expanded diameter. The secondary section provides a first endoleg having an upstream end that is received through the expanded diameter of one opening of the primary section, and a second endoleg having an upstream end that is received through the second opening of the primary section. The upstream ends of each endoleg, in its expanded state, is larger than the downstream portion of the respective endolegs and expands within the primary section to help assemble the graft in situ. The first and second endolegs also expand within the respective openings each is received within to assemble the stent graft in situ as well. The primary section is positioned within a blood vessel trunk, whereas the endolegs of the secondary section are positioned within a blood vessel branched from the blood vessel trunk. A typical application would be to place the primary section within the abdominal aorta infrarenally, with the endolegs positioned in the ipsilateral and contralaterial iliacs, respectively. By minimizing the number of stent segments in the primary section of the stent graft a lower delivery profile is achieved.

International Classification:

A61F 2/06

US Classification:

623 111

Abstract:

International Classification:

A61C 5/02
A61C 1/00

Abstract:

During root canal procedures, pulp may be removed from a tooth without disturbing the dentin by directing pulses of a heated liquid onto the pulp at particular temperatures and pressures to liquefy or gellify the pulp. The liquefied or gellified material is then aspirated away using the methods and apparatuses described herein. In some embodiments the heated liquid also functions to kill bacteria that may be present within the tooth.

Abstract:

An expandable mammary tissue implant including a shell having an anterior face and a posterior face, the anterior face having an upper pole portion and a lower pole portion meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant. The implant further includes a vertical tether member having first and second ends and a central region therebetween having an aperture therethrough. The central region is coupled to the anterior face of the implant at a location such that the injection zone is positioned within the aperture in the central region. The first and second ends of the vertical tether member are coupled to the posterior face of the implant.
