Patent number: 11660082Abstract: A dilation system for accessing a surgical target site to perform surgical procedures. In one version, the dilation system includes a wedge assembly and an actuating mechanism. The wedge assembly comprises includes a base and a plurality of blades extending from the base so that the distal end of the blades extend away from the base. The mechanism is operably associated with the blades so as to cause the distal end of the blades to move from a closed condition to an expanded condition.Type: GrantFiled: February 7, 2020Date of Patent: May 30, 2023Assignee: DePuy Synthes Products, Inc.Inventor: Stephen Heiman

Patent number: 9808232Abstract: A dilation system for accessing a surgical target site to perform surgical procedures. In one version, the dilation system includes a plurality of open sided dilators having non-circular cross sections and configured to slidably and non-rotationally engage with one another in a sequential manner. In another version, the dilation system includes an expandable dilator movable from a closed condition to an expanded condition.Type: GrantFiled: November 1, 2012Date of Patent: November 7, 2017Assignee: DePuy Synthes Products, Inc.Inventors: Stephen Heiman, Dustin Harvey, Corbett W. Stone, Kabir Gambhir, Timothy Anderson, Benjamin Arnold, Robert Bishop, Paul S. Maguire

Patent number: 9247944Abstract: A trialing and preparation system for preparing a disc space between two adjacent vertebrae is provided. The system includes a guide shaft, a trialing cage or spacer, a scraper and a driving shaft. The guide shaft supports the trialing spacer within the disc space and may include an angular adjustment for such access. The scraper sleeves over the guide shaft into an abutting relationship with the adjacent vertebrae. The driving shaft is coupled to the scraper by a pivoting and reciprocation mechanism that allows angular adjustment of the scraper. Also, reciprocation of the driving shaft reciprocates the scraper through a limited sweep of motion to remove osteophytes from the vertebrae.Type: GrantFiled: December 7, 2012Date of Patent: February 2, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Matthew Fenn, Stephen Heiman, Sean Saidha, Gregory Walters, Michael White

Patent number: 8157787Abstract: A pumping system for use in medical applications where liquids must be infused and aspirated from a mammalian patient, and whose economics are such that it is cost effective to simply dispose of it after a single use. The system features positive displacement pump(s) such as reciprocating pump(s) containing a damping mechanism to dampen out the peaks and valleys in the fluid pressure that is pumped, which is important for preventing cavitation. The system furthermore features a shut-off valve on the extraction side so that certain injected fluids such as contrast medium, are not immediately pumped out of the patient. In a preferred embodiment, the system also features means for independently controlling the fluid pressure/volume on the infusion and extraction sides, self-priming capability, a continuous fluid path, and visual air bubble detection, with viewports located at important points in the fluid path, such as at pumps and valves.Type: GrantFiled: August 16, 2011Date of Patent: April 17, 2012Assignee: Kensey Nash CorporationInventors: John E. Nash, Gregory Walters, Stephen Heiman, Jim Barnitz, Pete Fatone
