Publication number: 20130261597Abstract: Described herein is a novel drug delivery assembly having particular applicability to the field of orthopedic and surgical medicine. The devices and assemblies described herein enable the efficient application and retention of potentially expensive therapeutic materials to very specific locations, particularly those associated with voids in bone and tissue. One particularly unique aspect of the present invention involves the introduction of constructs which promote the retention of therapeutic material in the target area of application for beneficial use, for example by forming a proximal barrier that prevents leakage of the therapeutic material out of the target area. Additionally, the present invention provides unique devices and methods for surgical introduction of such constructs.Type: ApplicationFiled: August 17, 2012Publication date: October 3, 2013Applicant: BIOACTIVE SURGICAL, INC.Inventors: Richard H.

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.

Publication number: 20100217327Abstract: A plate includes a substantially rectilinear posterior tab and an anterior tab. The anterior tab includes a substantially rectilinear rear longitudinal part connected rigidly to the posterior tab such that they form between them a first angle of between about 90° and about 110° and a substantially rectilinear front longitudinal part which is inclined with respect to the substantially rectilinear rear longitudinal part such that they form between them a second angle which is between about 230° and about 250°. The second angle is at the same angular orientation as the first angle. The plate is thus shaped appropriately in relation to the calcaneus and can be placed in position in a minimally invasive manner.Type: ApplicationFiled: February 24, 2010Publication date: August 26, 2010Inventors: David W.

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.
