Patent number: 10441306Abstract: A surgical instrument includes a cutting member with an implement for cutting tissue, and a drive coupled to the cutting member to simultaneously rotate and translate the cutting member in response to a three applied to the drive. A method of cutting tissue includes positioning an outer member such that tissue is located within the outer member, engaging the tissue with an inner member, and simultaneously rotating and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut the tissue. The inner member is mechanically driven to undergo simultaneous rotation and translation.Type: GrantFiled: May 2, 2017Date of Patent: October 15, 2019Assignee: COVIDIEN LPInventors: Peter M. Cesarini, Karen Drucker, Rafal Jezierski, Roger R. Cassidy

Patent number: 8956347Abstract: A method and apparatus include determining a value of a parameter associated with operation of an electrosurgical probe having a particular probe design, and determining whether the value of the parameter is within a range of values that has been predetermined for the particular probe design to indicate that the probe is treating tissue in a desired manner. Power is delivered to the probe according to an algorithm based upon a determination that the value of the parameter is outside the range of values The algorithm delivers power in a pulsed profile including portions of low power and portions of high power. In one embodiment, the tissue treatment is ablation, the parameter is impedance, and the method limits tissue necrosis to less than 200 microns. In another embodiment, the tissue treatment is shrinkage, the parameter is temperature, and the method limits power delivery when the probe is not shrinking tissue.Type: GrantFiled: November 26, 2013Date of Patent: February 17, 2015Assignee: Smith & Nephew, Inc.Inventors: Douglas M. Lorang, Matthew E. Mitchell, Karen Drucker, Kobi Iki

Publication number: 20120247607Abstract: A sanitary cap for a sanitary end is provided. The sanitary cap includes a base which defines a central axis and has a peripheral edge. A flange extends from the peripheral edge along the central axis and a lip spaced from the base extends from the flange inwardly toward the central axis. The sanitary cap may include a crosslinked polyethylene foam or a breathable insert. A system including a sanitary hose and the sanitary cap is also provided. The sanitary hose includes a sanitary end. The sanitary cap is removably disposed on the sanitary end. The crosslinked polyethylene foam of the sanitary cap of the system is formed in the presence of nitrogen as a physical blowing agent, has a density of from 1 to 20 lb/ft3 when tested in accordance with BS ISO 7214 1998 Skin/Skin, and is a Class VI foam as defined by the United States Pharmacopeia.Type: ApplicationFiled: March 31, 2011Publication date: October 4, 2012Applicant: UFP TECHNOLOGIES, INC.Inventors: Ronald MacNeill, Tuna Sava, Karen Drucker
