Publication number: 20240023989Abstract: Adjustable-length surgical access devices are disclosed herein, which can advantageously allow an overall length of the access device to be quickly and easily changed by the user. The access devices herein can reduce or eliminate the need to maintain an inventory of many different length access devices. In some embodiments, the length of the access device can be adjusted while the access device is inserted into the patient. This can reduce or eliminate the need to swap in and out several different access devices before arriving at an optimal length access device. This can also reduce or eliminate the need to change the access device that is inserted into a patient as the depth at which a surgical step is performed changes over the course of a procedure. Rather, the length of the access device can be adjusted in situ and on-the-fly as needed or desired to accommodate different surgical depths.Type: ApplicationFiled: September 30, 2023Publication date: January 25, 2024Inventors: Michael White, Joern Richter, Jan Klett, Stephane Gully, Veronique Zollmann, Richard Kocharian

Patent number: 11712264Abstract: An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.Type: GrantFiled: January 26, 2021Date of Patent: August 1, 2023Assignee: Medos International SarlInventors: Daniel Thommen, Joern Richter, Michael Wang, Richard Assaker, Richard Fessler, Christoph Mehren, Seang Beng Tan, William Taylor, Eric Buehlmann, Michael White, Piet Hinoul, Richard Kocharian

Patent number: 7955315Abstract: A laparoscopic medical fluid delivery device includes a catheter having an articulating tip formed with shape memory properties and thus having a pre-shaped curvature. A tubular member is reciprocatingly slidable axially on the catheter to selectively cover and uncover portions of the articulating tip to thereby selectively vary the degree of curvature of the articulating tip. An actuator operatively linked to the tubular member selectively moves the tubular member reciprocatingly on the catheter. The pre-shaped articulating tip of the catheter is constrained by the tubular member from articulating to the pre-shaped curvature when the tubular member covers the articulating tip, and bends to a selected degree of curvature when the articulating tip is at least partially uncovered by the tubular member.Type: GrantFiled: July 24, 2006Date of Patent: June 7, 2011Assignee: Ethicon, Inc.Inventors: Marc Feinberg, Jessica Liberatore, Richard Kocharian, Bruce E.
