Patent number: 9757132Abstract: A device has been developed to augment the rotator cuff tendon tissue as it proceeds in healing. The device has two purposes: to provide initial stability to the rotator cuff repair site to allow early mobilization of the upper extremity of the patient, and to allow for reinforcement of rotator cuff tendon repairs to increase the likelihood of successful rotator cuff tendon repairs. The device consists of an inter-connected, open pore structure that enables even and random distribution and in-growth of tendon cells. The braided structure allows for distribution of mechanical forces over a larger area of tissue at the fixation point(s).Type: GrantFiled: March 24, 2010Date of Patent: September 12, 2017Assignee: Biorez, Inc.Inventors: Cato T.

Patent number: 9700446Abstract: A stent combined with a positioning apparatus to effectively place the stent at a precise deployment site within a narrowed vascular region such as an artery. The stent is maneuvered through the vessel and is guided by a guiding catheter up the vessel to where the narrowing is located. Upon exiting the guiding catheter and approaching the deployment site within the coronary artery, a deployment site locator expands to contact the vascular structure and, thereby, effectively position the stent at the deployment site within the narrowed vessel. This system apparatus and method is particularly useful for stent placement at an ostium (origin) of a vessel.Type: GrantFiled: August 28, 2012Date of Patent: July 11, 2017Assignee: Chambers Technology Inc.Inventor: Jeffrey W.
