International Classification:

A61B 1900

US Classification:

128899, 606116, 600434

Abstract:

This invention is an improved tissue localizing device for fixedly yet removably marking a volume of tissue containing a suspect region for excision without penetrating that volume. This invention also encompasses methods for deployment of the localizing device and its excision along with the marked tissue volume. At least one locator element is deployed into tissue and assumes a predetermined curvilinear shape to define a tissue border containing a suspect tissue region along a path. The locator element path preferably encompasses the distalmost portion of the tissue volume without penetrating that volume. Multiple locator elements may be deployed to further define the tissue volume along additional paths defining the tissue volume border that do not penetrate the volume. Polar and tangential deployment configurations as well as a locator element that may be cold-formed by a die in the distal portion of the deployment tube into a permanent arcuate shape is also disclosed.

US Classification:

378 37, 378 68, 378208

Abstract:

According to the present invention, improved methods and apparatus are provided for providing cushioning and other ergonomic surfaces on devices requiring the patient or tissue to be compressed, such as radiography machines, fluoroscopy units, mammography units and the like. In particular a radiolucent pad element is provided for releasable attachment to at least one surface of a compression device to be used under x-ray, for example, during mammography. The pad element of the present invention can be disposable or constructed to be reusable and in some cases may be applied directly to the patients breast. Furthermore, a cushioned paddle is provided wherein the compression paddle and the cushion can be separately or integrally formed.

US Classification:

604500, 604 34, 60416706, 60416407, 60416502, 604171, 251 4

Abstract:

According to the present invention, improved methods and apparatus are provided for regaining hemostasis or otherwise minimizing leakage during endoluminal, surgical or percutaneous intraluminal procedures, and for providing a seal during laparoscopic surgical procedures where there is leakage of the CO insufflation, when the primary means of hemostasis or pneumatic CO seal is compromised or fails. More particularly the present invention relates to devices having a front hub and a rear hub, one or other of which is adapted to retain a compression seal such that when the front and rear hub are matingly engaged, axial and radial pressure is applied to the compression plug and any devices located therebetween, thereby achieving a seal. The compression device can be applied while a guidewire or additional devices remain within the leaking sheath or trocar, thereby allowing the physician to maintain hemostasis or adequate CO insufflation, without exchanging the introducer sheath or laparoscopic port.
