Patent number: 5741228Abstract: An implantable access device for allowing repeat access to a site, space, device, or other object, fluid, tissue or region within the body of a patient. The implantable device, in one embodiment, includes a housing having an elongated open guidance channel that leads to an entrance orifice, a valve assembly communicating with the entrance orifice, and an exit orifice. The device permits access via the percutaneous insertion of an accessing filament such as a needle through the entrance orifice and into the valve assembly, which opens to allow the passage of fluids or other filaments such as guide wires or optical fibers. The device can be used for the introduction of therapeutic agents, for the infusion or withdrawal of fluids, or for the introduction of sensing, sampling, or treatment devices to another implanted device or to regions within the patient.Type: GrantFiled: February 17, 1995Date of Patent: April 21, 1998Assignee: Strato/InfusaidInventors: Gregory H.

Patent number: 5735445Abstract: A surgical stapler having a supporting frame, 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 in a manner to enable the surgeon to substantially simultaneously place one or more rows of surgical staples in organs or tissue. The device, while at all times permitting approximation of the cartridge relative to the anvil, provides a novel lockout feature for positively preventing retiring if the staple cartridge is spent. In this way, unlike the prior art devices, the device of the present invention can be used as a clamping mechanism even after the staples have been fired.Type: GrantFiled: March 14, 1997Date of Patent: April 7, 1998Assignee: United States Surgical CorporationInventors: Claude A.
