摘要:
Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).

摘要:
Systems and method for sealing vascular penetrations rely on placement of a temporary barrier on the posterior side of the penetration. Penetrations are then sealed by delivering a hemostatic gel to a region over the penetration, where the barrier both inhibits loss of the gel and promotes back flow of blood into the gel. A combination of natural clotting factors in the blood and hemostatic agents in the gel promote rapid and effective sealing of the vascular penetration. Specific systems for performing the method include a barrier carrier for temporary placement of the barrier within the blood vessel and a gel delivery tube which may be positioned within a tissue tract or line of penetration simultaneously with the barrier carrier to deliver the hemostatic gel.

A surgical stapler for use by a surgeon to place one or more rows of surgical staples in organs or tissue. The stapler is of a character having a supporting frame, a replaceable staple cartridge, an anvil, a mechanism for approximating the cartridge relative to the anvil, and a mechanism for firing the device so as to crimp the staples against the anvil. The device, while at all times permitting approximation of the cartridge relative to the anvil, provides a novel safety mechanism that clearly indicates to the surgeon that the staples have been fired from the staple cartridge and simultaneously disables the device until it is manually reset.

A medical backcheck valve includes a hollow housing containing an upwardly biased piston assembly for controlling liquid flow therethrough. The piston assembly comprises a substantially rigid plug having one end protruding from the upper end of the housing, and a flexible sheath covering having a relatively small diameter upper end surrounding the plug, a main seal for controlling flow through said first flow space, and a tubular lower end, secured at the bottom of the housing, for preventing liquid from entering within the covering.
