Publication number: 20240325620Abstract: A fat harvesting systems and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.Type: ApplicationFiled: May 8, 2024Publication date: October 3, 2024Inventors: Karan Chopra, Joseph M. Gryskiewicz, Richard A. Thompson, II, Reed O. Saunders, Evan M. Leingang, Thomas A. Tedham, Mohamed A. Mohamed, Jacob T. Wilson, Brett J. Herdegen, Jason N. Scherer, Landon Hove Dinger, Justin A.

Patent number: 11517714Abstract: The present disclosure provides a medical device comprising an actuator restraining assembly configured to assist in restraining a catheter shaft in a deflected configuration. The actuator restraining assembly may include a brake element, a release element, a connecting sheath, and a connecting rod disposed in a catheter handle, wherein the connecting sheath and connecting rod are attached to an actuator mechanism, and wherein the at brake element is attached to the connecting sheath and the release element is attached to the connecting rod. The brake element is sized and configured to contact an inner wall of the handle to thereby provide resistance to movement of actuator mechanism in a proximal direction with respect to the handle. In one embodiment, the actuator restraining assembly is configured to allow for temporary, i.e., reversible, restraining of the catheter shaft in the deflected configuration.Type: GrantFiled: May 7, 2020Date of Patent: December 6, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Brett A.
