Abstract: The present is directed to systems for ex vivo testing performance of a hemostatic or sealing product attached to an animal organ and fully covering a cored channel in said organ, comprising: a pressure sensor positioned proximate to said hemostatic or sealing product in said cored channel; a monitoring or recording device configured to receive pressure readings from said pressure sensor; and a pressurized fluid source connected to said cored channel and configured to supply said pressurized fluid into said cored channel under constant or variable pressure. The present invention is also directed to methods of use for such systems.

Abstract: A system for testing sutures includes a test bench having a rotatable table, a framework supporting the test bench and the rotatable table above a surface, and a continuous passive motion (CPM) machine mounted on the rotatable table. The CPM machine is configured to rotate between a first position in which the CPM machine is upright and located above the rotatable table and a second position in which the CPM machine is inverted and located below the rotatable table. The system includes a fluid supply subsystem for directing an infusion fluid toward the CPM machine, a pump for circulating the infusion fluid in the fluid supply subsystem, a heat exchanger for heating the infusion fluid, a fluid collection tray located below the CPM machine and the rotatable table, and a pressure monitoring subsystem for monitoring a pressure level of the infusion fluid.

Abstract: The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections so as to improve tissue viability, prevent tissue infection, and to prevent leakage. The present invention further relates to an expandable compression device for application to anastomotically joined tubular tissues, comprising: an upper ring-shaped or disk-shaped flange at a distal end of said device connected to a lower ring-shaped inflatable flange at a proximal end of said device via a hollow cylindrical tubular body, with an opening forming an axial passage through said upper flange, lower flange, and tubular body.

Abstract: The present invention relates to circular anastomosis stapler and kits comprising reinforcing buttress materials and fixation tools that are slidably installed on the anvil shaft of such staplers which provides a temporary mechanical fixation of a reinforcing buttress to the anvil surface of a circular stapler during the insertion of the anvil into the tubular tissue. When the anvil, loaded with the buttress, is in the desired location, the fixation tool is pulled back along the anvil shaft and removed. The shaft is then connected to the stapling head and the stapling is performed. The present invention also relates to methods for using the kits and devices therein.

Abstract: Devices and methods for applying sealants to surgical instruments. In one embodiment, a surgical device is described that can include at least one nozzle formed at a proximal end of the device that is configured to receive a sealant, as well as an applicator formed at a distal end of the device that is configured to deliver the sealant received by the at least one nozzle. The applicator can be configured to interface with at least one of a first and second jaw of a surgical stapler such that the sealant delivered from the applicator can be deposited into a plurality of openings formed in the surgical stapler.

Abstract: A novel system and apparatus for testing surgical fastening devices in an ex-vivo body wall wound closure simulation device is disclosed. The system is particularly useful with simulating abdominal wall wound closure. The system has a body wall curvature approximator device, a tissue fixation system, and a tissue support and tensioner device. The system provides for anatomically correct presentation and tensioning on body wall tissue specimens for ex-vivo wound closure simulation. The system may also be used for other anatomic tissue specimens in addition to body walls.

Abstract: The present invention relates to circular anastomosis stapler kits that deliver a therapeutic agent followed by stapling of tissue. Each device has a stapling head with a shaft extending from said stapling head and a removable anvil and an interchangeable delivery head for delivering a therapeutic agent into the tissue.

Abstract: Adjunct material and methods of using adjunct material to reinforce a staple line are provided herein. In general, adjunct material can be used to maintain a seal in tissue and prevent stapled tissue from tearing. This adjunct material can be coupled to a jaw of a surgical stapler, and can be deployed into tissue along with the staples. In some embodiments, the adjunct material can be sized and shaped so that a portion of the material extends laterally outside of the staple line and distributes strain to tissue outside of the staple line. In certain aspects, sealant can be applied to the staple line and to the adjunct material in various ways to further seal the tissue and/or prevent leaks from forming in the tissue.

Abstract: A suction device includes a suction cup having a vacuum inlet for connection to a vacuum source. The suction cup has a wall defining a cavity that is in fluid communication with the vacuum inlet and an engagement surface for engaging a tissue surface. The suction cup is formed of a material that minimizes injury to the tissue surface contacted by the engagement surface and tissue captured when the vacuum is applied and permits the captured tissue to be perfused during use of the suction device.
