Publication number: 20210236184Abstract: A sternotomy closure technique is suitably carried out with a cerclage mechanism, which is capable of maintaining proper bony compression (within a desired range) across the sternum cut, in spite of a range of external forces and significant lateral distraction due to these external forces. The sternum fragments are aligned in apposition disposed around a longitudinal seam and secured with a resilient element. The resilient element is tensioned to a desired tension to compress the sternum to a desired compression range. The resilient element is then elongated and contracted while accepting multiple cycles of physiological distracting forces across the sternum while maintaining contact pressure across the longitudinal seam within a desired range for a length of time sufficient for bony healing. The resilient element is preferably a polymer cable comprising an elongated elastic polymeric core coaxially surrounded by a sheath woven from ultra-high molecular weight polyethylene strands.Type: ApplicationFiled: April 23, 2021Publication date: August 5, 2021Inventors: Clyde Ronald Pratt, Adam Lee Nelson, Robert Arthur Bruce, Vineet Kumar Sarin

Patent number: 9107720Abstract: A cable tensioning system includes a reaction frame which contains a sliding platform arranged to move linearly within the frame, and a clam-type cleat attached to the sliding platform. The cleat features one or more grooves, each of which comprises two arrays of opposing ridges that converge to form a V-shape groove adapted to receive a length of cable. The ridges of each groove are tilted relative to an axis perpendicular to the groove's longitudinal axis, such that the cable is progressively captured between the ridges of the opposing arrays as it settles into the crotch of the groove when moved in a first direction, and can be disengaged from the cleat by relaxing the axial force on the cable and moving it in the opposite direction. A linear actuator mechanism may be coupled to the sliding platform to move the platform with respect to the reaction frame.Type: GrantFiled: June 24, 2013Date of Patent: August 18, 2015Assignee: Kinamed, Inc.Inventors: William Ralph Pratt, Robert Bruce, Stephen F Howard, Vineet Kumar Sarin, Clyde Ronald Pratt, Richard L Kendall

Patent number: 8535329Abstract: The invention includes a method for tracking the human scapula during shoulder surgery, by a trackable device fixed to the coracoid process of the scapula. A device of the invention allows a trackable target to be fixed to the coracoid process by bone screws and an anchor. In one embodiment, a releasable coupling is provided between the anchor and the trackable target.Type: GrantFiled: October 29, 2004Date of Patent: September 17, 2013Assignee: Kinamed, Inc.Inventors: Vineet Kumar Sarin, William Ralph Pratt, Kyle Craig Pilgeram, Richard Lee Kendall

Patent number: 8271066Abstract: The invention includes a method of determining a surgical patient's pelvic position and inputting that position into a computer via a tracking system, suitable for use in navigating partial or total hip replacement surgery. The patient is first aligned with anatomical reference points in relation to corresponding locating features on a patient positioner. The positions of index features on the patient positioner are then acquired via a tracking system. Based on the positions of the index features and their known relationship to the locating features, the locations of the anatomical reference features are calculated and a pelvic plane is defined therefrom. The invention also includes a surgical tool for mounting a trackable target to a human bone, suitable for fixation to a human femur. This tool includes a removable bone clamp and a releasable coupling member, integrated with said removable bone clamp.Type: GrantFiled: May 15, 2008Date of Patent: September 18, 2012Assignee: Kinamed, Inc.Inventors: Vineet Kumar Sarin, Robert A. Bruce, William Ralph Pratt, Clyde Ronald Pratt, Roger C. Carignan

Patent number: 8002772Abstract: A surgical tool for mounting a trackable target to a human bone, suitable for fixation to a human femur. The tool includes a removable bone clamp and a releasable coupling member which is integrated with the removable bone clamp. The releasable coupling member is arranged to mate with a compatible coupling member mounted on the trackable target to establish a predetermined spatial relationship between the bone clamp and trackable target. The releasable and compatible coupling members form a releasable connection which is mechanically constrained to re-engage only in a re-engaged position that accurately recaptures the predetermined spatial relationship.Type: GrantFiled: August 8, 2003Date of Patent: August 23, 2011Assignee: Kinamed, Inc.Inventors: Vineet Kumar Sarin, Robert A.

Patent number: 7780681Abstract: The invention includes: a locating system; a computer, interfaced to the locating system and interpreting the positions of tracked objects in a generic computer model of a patient's hip geometry; a software module, executable on the computer, which defines the patient's pelvic plane without reference to previously obtained radiological data, by locating at least three pelvic landmarks; and a pelvic tracking marker, fixable to the pelvic bone and trackable by the locating system, to track in real time the orientation of the defined pelvic plane. Preferably, the system also includes a femoral tracking marker, securely attachable to a femur of the patient by a non-penetrating ligature and trackable by the locating system to detect changes in leg length and femoral offset.Type: GrantFiled: January 27, 2004Date of Patent: August 24, 2010Assignee: Kinamed, Inc.Inventors: Vineet Kumar Sarin, Mark Edward Apgar, Robert A.
