Publication number: 20220387053Abstract: Inverting tube apparatuses having an inverting tube (e.g., a knitted tube) that is configured to roll into an inversion support catheter and capture material from within a body lumen such as a blood vessel, in which the knitted tube is configured to prevent locking down onto the outside of the inversion support catheter. The inversion support catheter may include an expandable funnel at the distal end thereof having an interior profile that is adapted to capture and break apart hard material captured by the tractor so that it may be pulled into the inversion support catheter for removal.Type: ApplicationFiled: August 11, 2022Publication date: December 8, 2022Applicant: STRYKER CORPORATIONInventors: Michael P. Wallace, Jayson Delos Santos, Skott E. Greenhalgh, Winnie Tang, Clifford Van

Publication number: 20220346815Abstract: Inverting tube apparatuses and methods of using same for removing large amounts of material from a body lumen. The apparatuses and methods described herein may use a depot for holding, in a compressed configuration, a length of the flexible tube configured to invert over the distal end of an inversion support catheter to capture material within a body lumen. The depot is configured to facilitate the release of the flexible tube with a low release force, and in a manner that prevents snagging or binding of the flexible tube either on the body of the catheter or when rolling and inverting into the inversion support catheter.Type: ApplicationFiled: July 18, 2022Publication date: November 3, 2022Applicant: STRYKER CORPORATIONInventors: Michael P. WALLACE, Skott E. GREENHALGH, Jayson Delos Santos

Publication number: 20060241671Abstract: An access port for performing surgical procedures within an insufflated body cavity is disclosed. The port is formed from a duct that is inserted into the body cavity, the duct having a stiff sidewall to prevent collapse. The duct contains a flexible tube that has a constricted shape that forms a seal around a surgical instrument inserted through the duct. The tube has an inner membrane with a low coefficient of friction to facilitate passage of surgical instruments through the duct. The tube has an elastic outer membrane to bias it into the constricted shape. The tube may also be pressurized into the constricted shape by gas, gel or liquid. The tube itself may also form a seal in the absence of the tool, or a second seal, such as a duckbill valve, may be positioned within the duct.Type: ApplicationFiled: April 20, 2006Publication date: October 26, 2006Applicant: Stout Medical Group, LLCInventor: E.

Publication number: 20060052800Abstract: A tool for implantation of a flexible substrate into soft tissue is disclosed. The tool has a shaft with a bore. A penetrator tip is positioned at a distal end of the shaft. A handle is positioned at the proximal end. A push rod extends through the bore and is attached at one end to the penetrator tip, and at the other end to a trigger mounted on the handle. The penetrator tip is biased toward the shaft by a spring and captures the substrate between itself and the shaft. The shaft is inserted into soft tissue, drawing the substrate with it. Pulling the trigger releases the substrate from the tool. The shaft is withdrawn, leaving the substrate within the tissue.Type: ApplicationFiled: September 6, 2005Publication date: March 9, 2006Applicant: Secant Medical, LLCInventor: E. Greenhalgh
