Patent number: 10130371Abstract: Embodiments of aortic occlusion devices are described herein that include radially expandable and collapsible proximal and distal end portions, such as annular self-expanding stents or frames, that are configured to radially expand within an aorta to secure the device within the aorta. The devices can also include a catheter extending axially between the distal end portion and the proximal end portion and a porous covering, or filter, positioned around the catheter and between the proximal end portion and the distal end portion and configured to filter emboli from blood flowing into upper-body arteries. The device can further include a one-way valve positioned at or adjacent to the distal end portion of the device and configured to restrict retrograde blood flow through the device toward the heart.Type: GrantFiled: May 13, 2014Date of Patent: November 20, 2018Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Mark Dehdashtian, Teodoro S. Jimenez, Nathan Satter, Fabian D. Schroeder, Raffaele Mazzei, Jeff Kosmoski, Shaun Zamani, Adam Yestrepsky

Patent number: 9149306Abstract: A device for immobilizing adjacent spinous processes can comprise a first element, a second element, and a spacer element. The first element can have a side configured to grip first sides of the adjacent spinous processes and a first separation bar that extends between the adjacent spinous processes when the first element and the spinous processes are engaged. The spacer element can have an adjustment bar and a second separation bar. The second element can have a side configured to grip second sides of the adjacent spinous processes and a clamping feature configured to selectably lock the first separation bar and the adjustment bar in place. The second separation bar can extend between the adjacent spinous processes when the second element and the adjacent spinous processes are engaged.Type: GrantFiled: June 21, 2012Date of Patent: October 6, 2015Assignee: SeaSpine, Inc.Inventors: Shahram Shaun Zamani, Nicholas M. Cordaro, Colin Matthew Smith

Patent number: 8585402Abstract: A dental drill guide system, including a handpiece guide which interfaces with a custom surgical guide. The custom surgical guide may be designed based on patient-specific data, such as medical images, for example, and fits conformingly over at least a portion of the patient's dentition at the implant site. The handpiece guide is attachable to an existing dental handpiece, and includes a guide protrusion that interfaces with a guide receptacle of the surgical guide to position and guide the movement of the drill along a desired trajectory. The guide receptacle may have a curved shape to allow for varying the position of the handpiece to aid surgeon access in the drilling procedure.Type: GrantFiled: August 26, 2009Date of Patent: November 19, 2013Assignee: Zimmer Dental, Inc.Inventors: Tyson K. Vogel, Shahram Shaun Zamani, Sean B. Cahill, Suneel Ranga Sai Battula

Publication number: 20120290010Abstract: Devices and systems related to an improved spinal pedicle based construct are disclosed herein along with the related method of manufacturing and operation thereof. The improved spinal pedicle based construct may include a flexible membrane(s) or mechanism(s) incorporated between the anchoring component and the longitudinal membrane. The flexible membrane(s) incorporated may provide controlled motion of the functional spine unit connected to the anchoring component with respect to the posterior construct. Moreover, when the patient moves his or her back, the flexible membrane(s) may also divert a force away from the anchoring component, thereby reducing the chances of bone cracking.Type: ApplicationFiled: November 17, 2010Publication date: November 15, 2012Applicant: Seaspine, Inc.Inventors: Shahram Shaun Zamani, Nicholas M.
