Patent number: 11497669Abstract: 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.Type: GrantFiled: April 27, 2019Date of Patent: November 15, 2022Assignee: Ethicon, Inc.Inventor: John Matonick

Patent number: 10278703Abstract: 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.Type: GrantFiled: March 21, 2016Date of Patent: May 7, 2019Assignee: Ethicon, Inc.Inventors: Nir I.

Patent number: 9924946Abstract: 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.Type: GrantFiled: June 10, 2014Date of Patent: March 27, 2018Assignee: Ethicon LLCInventors: Michael J.

Publication number: 20150351753Abstract: 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.Type: ApplicationFiled: June 10, 2014Publication date: December 10, 2015Inventors: Frederick E.
