Patent number: 9381292Abstract: An implantable device that continuously regulates the blood glucose levels of a type 1 diabetes mellitus patient is provided. The device which is implanted in the bloodstream, relies on a microfluidic chip and a microsieve that efficiently separate leukocytes away from an amount of blood received and an islet compartment made up of multiple islets (beta and alpha cells) from at least one compatible donor pancreas source. During hyperglycemia, insulin is produced by the beta cells to remove excessive sugar from the blood. Similarly, during hypoglycemia, glucagon is secreted by the alpha cells to bring the blood glucose level back to normal. The device is self-sustaining without relying on an electrically-powered insulin pump or refills of exogenous insulin.Type: GrantFiled: July 24, 2014Date of Patent: July 5, 2016Inventor: Kamal Ahmed Aljohani

Patent number: 7189262Abstract: A prosthetic tibial component for a prosthetic total knee joint includes two constructs, one being a metal base that engages a bone and the other being a polyethylene bearing that attaches to the metal base and articulates with a femoral prosthetic component on a opposing side of the joint. The metal base is composed of two metals, one of which engages the bone surface and the other of which engages the polyethylene bearing. Each of the metals is selected for its function. The first metal is selected to provide a superior bone-engaging face, while the second metal is selected to provide a superior polyethylene-engaging face. By combining the different material characteristics of two different metals there is formed a superior bone-engaging face and a superior polyethylene-engaging face.Type: GrantFiled: November 25, 2003Date of Patent: March 13, 2007Assignee: Hayes Medical, Inc.Inventors: Daniel E.

Patent number: 7112219Abstract: Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning a spacing filling device outside and adjacent the heart wall such that the device applies an inward force against the heart wall acting on the valve. A substantially equal and opposite force may be provided by securing the device to the heart wall, and/or a substantially equal and opposite outward force may be applied against anatomical structure outside the heart wall. The inward force is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example. The space filling device may be implanted by a surgical approach, a transthoracic approach, or a transluminal approach, for example. The space filling portion may be delivered utilizing a delivery catheter navigated via the selected approach, and the space filling portion may be expandable between a smaller delivery configuration and a larger deployed configuration.Type: GrantFiled: November 10, 2003Date of Patent: September 26, 2006Assignee: Myocor, Inc.Inventors: Robert M.

Patent number: 7094260Abstract: A biodegradable common bile duct stent and the method for preparing thereof are provided. The stent is made of biodegradable polymeric material with incorporation of X-ray opaque components. The stent adapts to the anatomical shape of the CBD or it can be sutured together with the wall of the bile duct. After placing the stent in the duct, it maintains its position and does not slip. The circular tube of the stent being suitably sized and having multiple ring-shaped protruding rims at the outer wall and/or with larynx structure, leakage and outflow of the bile are thereby prevented. It can be manufactured by a conventional injection-molding or an extrusion-blowing technique. In surgical operation on the bile duct, the stent can replace the T-tube which is conventionally used to support the duct and guide bile drainage.Type: GrantFiled: April 12, 2004Date of Patent: August 22, 2006Assignees: Changhun Institute of Applied Chemistry Chinese Academy of Science, First Hospital, Jinlin UniversityInventors: Xiabin Jing, Tongjun Liu, Xuesi Chen, Shaohui Liu, Xiaoyi Xu, Xinchao Bian, Youzhu Li, Kai Zhang

Patent number: 7090694Abstract: A stent pattern includes an improved portal region for repairing a main vessel and a side branch vessel forming a bifurcation. More particularly, the stent has rings aligned along a common longitudinal axis that are connected by links, where the stent has a proximal section, a distal section, and a central section (portal region). The number of rings and the expanded diameter of the sections are varied to create a “trap door” capable of expanding to a slightly larger diameter than the proximal section and the distal section of the stent. The configuration of the stent pattern of the portal region prevents the occurrence of portal overlap of immediately adjacent rings into the portal region during stent deployment. The stent is implanted at a bifurcation so that the proximal section and the distal section are in the main vessel, and the central section contacts at least a portion of the opening to the side branch vessel.Type: GrantFiled: November 19, 2003Date of Patent: August 15, 2006Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Grayson Morris, Rommel Lumauig

Patent number: 7083648Abstract: Percutaneous skin access devices include a plurality of locked connecting units mounted to the exterior surface of an implantable medical object which, in position, is configured to penetrate the skin of a subject. The locked connecting units may be mounted directly onto the desired surface of the exterior of the device or may be held on a substrate sheet, which is mounted to the exterior surface of the device. In position, the locked connecting units engage with soft tissue which can include the skin to form a bio-junction layer which includes mechanical and bio-sealing connection between the device body and the soft tissue. The configuration at the bio-junction layer secures the medical object in location in the subject even for long-term indwelling applications in a manner, which inhibits soft tissue infection. The locked connecting units may be rigid or semi-rigid for longer-term indwelling applications, and semi-rigid and/or resilient for shorter term indwelling applications.Type: GrantFiled: November 30, 2000Date of Patent: August 1, 2006Assignee: East Carolina UniversityInventors: Chang Yu, Glenn Harris

Patent number: 7083643Abstract: This invention is directed to methods for treating aneurysms wherein the aneurysmal sac is filled with a non-particulate agent or plurality of such agents and/or with a fluid composition which solidifies in situ. Filling of the aneurysmal sac employs sufficient amount of the non-particulate agent or plurality of such agents and/or the fluid composition to inhibit blood flow into the aneurysm sac. In addition, the methods of this invention also provide for non-endogenous isolation of the parent artery proximal and distal to the aneurysmal sac from systemic blood flow of the treated mammal. The combination of these features provides for treatment of the aneurysmal sac while, at the same time, inhibiting aneurysm formation and/or regrowth in the diseased portions of the arterial wall proximal and distal to the treated aneurysm.Type: GrantFiled: March 17, 2003Date of Patent: August 1, 2006Assignee: Micro Therapeutics, Inc.Inventors: Thomas J.
