US Patent:

20030114925, Jun 19, 2003

Filed:

Dec 18, 2001

Appl. No.:

10/022887

Inventors:

Gerardo Molina - Leander TX, US

International Classification:

A61F002/24

US Classification:

623/002380, 623/002420, 427/002240

Abstract:

A mechanical prosthetic heart valve with a pyrolytic carbon valve body having re-enforcing fibers in the valve body. The fibers may be short segments of graphite wire or continuous fibers may be wrapped around the valve body. The fiber may be arranged in loops and formed in repeating patterns around the valve body. Also, methods for making a prosthetic heart valve body having a first layer of pyrolytic carbon that is substantially free from fiber, a second layer comprised of fibers encased in pyrolytic carbon, and a third layer that is substantially free from fiber. The method may comprise placing a mandrel in a fluidized bed, coating the mandrel with a first layer of pyrolytic carbon, introducing a fiber, coating the mandrel and the fiber with a second layer of pyrolytic carbon, and coating the mandrel with a third layer of pyrolytic carbon.

A61B 18/14

Abstract:

The present disclosure includes an electrosurgical apparatus for treating tissue at a target site. The apparatus has a shaft with a proximal end and a distal portion, the distal portion comprising a return electrode and electrode support. There is also at least one active electrode on the shaft distal portion, which has a proximal portion and a distal portion and a plurality of aspiration apertures disposed therebetween. These apertures are fluidly connected to a fluid aspiration cavity that is located within the electrode support, and the cavity is connected with a fluid aspiration element that is located along the shaft. The plurality of apertures vary in size and are generally arranged so that the larger sized apertures are disposed towards the electrode proximal portion and the smaller sized apertures are generally located towards the electrode distal portion.
