Patent number: 9775717Abstract: A subtalar joint prosthesis that is adapted to replace the natural subtalar joint that exists between a patient's talus and calcaneus bones includes talar and calcaneal components. Each of these is configured to have a shape that is herein defined as being a portion of the boundary surface of a frustum. Meanwhile, these components' inner surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each components's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection for the implantation of these components.Type: GrantFiled: August 15, 2011Date of Patent: October 3, 2017Inventors: Lew C. Schon, Christopher Chiodo, Brent G. Parks, David Aaron, Zeynep B. Dine

Patent number: 8211107Abstract: The intramedullary fixation device for use in fixing the relative position between a tubular bone and an adjoining bone has, according to the present invention, an intramedullary nail that is inserted into the medullary canal of the tubular bone whose position is to be fixed, an elongated blade for insertion into the adjoining bone whose position is to be fixed relative to that of the tubular bone, a coupling element for fixing and locking the relative position of the nail and blade after their insertion, and a means for locating and positioning within the bones to-be-treated the nail and blade. Furthermore, the blade has a cross-sectional shape that is configured in consideration of the geometry of the bone into which the blade is to-be-placed and so as to enhance the ability of the blade to stabilize the bone, and these elements are configured so that they do not have to be decouple during the process of inserting the nail and blade.Type: GrantFiled: May 10, 2007Date of Patent: July 3, 2012Assignee: Concepts In Medicine, LLCInventors: Brent G.

Patent number: 7506543Abstract: According to a first embodiment of our invention, a monitoring device is placed above, within, or on the bottom of a cast, boot, shoe, or other lower extremity immobilization or protective device, and has one or more single or cluster of pressure sensitive chambers designed to burst at a predetermined force or weight. The pressure sensitive chambers may be filled with air, liquid, semi-liquid, or particulate material. Once properly positioned, the device serves to detect and alert one or more individuals to the fact that weight-bearing has occurred and/or that a certain amount of force has been transmitted across the bottom or other portion of the cast, boot, shoe, mat, sock, insole, or lower extremity immobilization or protective device in a setting where such pressure could be deleterious or harmful (including situations where patients are recovering from a bony fracture, tendon injury, and recent lower extremity surgery).Type: GrantFiled: February 23, 2006Date of Patent: March 24, 2009Inventors: Christopher P.
