The rehabilitation devices preferably have a plurality of selectable power settings that correspond to one or more rehabilitation-oriented actions or functions of the rehabilitation devices. For example, the power of the rehabilitation device may be selected based on a need, ability, muscle-power and/or physiological characteristics of the user. For instance, a rehabilitation device may be operated at a relatively low power setting to allow a patient to use his or her own muscle power when moving with the rehabilitation device. The rehabilitation device may also include an adjustable sensitivity level that corresponds to a user difficulty in triggering a particular rehabilitation-oriented action. The powered rehabilitation device may also temporarily be used to train a user in interacting with a passive or more conventional prosthetic device.Type: ApplicationFiled: October 10, 2014Publication date: April 9, 2015Inventor: Kim De Roy

Patent number: 8939917Abstract: A method for measuring cartilage defects within a subject includes surgically exposing a joint or cartilage surface. The exposed joint or cartilage surface having at least one defect, and the method may generating a cast of the at least one defect. The method may also include measuring a parameter of the cast, thereby estimating a characteristic of the defect.Type: GrantFiled: February 16, 2010Date of Patent: January 27, 2015Assignee: ImaTx, Inc.Inventor: Rene Vargas-Voracek

Patent number: 8915743Abstract: A system, method and device for simulating a medical procedure include a haptic mechanism controllable to provide feedback to a user manipulating a medical device. In an embodiment, a pair of three degree of freedom haptic devices are coupled to provide six degree of freedom measurement and force/moment feedback to the user. The six degree of freedom haptic device may be configured to provide different resolutions for different degrees of freedom, depending on simulation requirements. In an embodiment, a load cell is used to provide higher resolution in a dimension determined to be of greater criticality to realistic simulation.Type: GrantFiled: August 6, 2009Date of Patent: December 23, 2014Assignee: SimQuest LLCInventor: Dwight Meglan

Patent number: 8875398Abstract: A system including a method and associated structures creates efficiencies in the manufacture of prosthetic tooth support frameworks. Pre-manufactured teeth with matching internal keys are used in the setup of a patient prototype. Each key includes a shaft, a cervical platform, a retention knob and preferably at least one channel for the expulsion of excess adhesive fluid. The cervical platforms are shaped to provide intimate contact with a base of their respective tooth. The same tooth/key pairs are then used to make a framework pattern from the setup positioning. The pattern can be cast or scanned for direct machining to produce the finished framework.Type: GrantFiled: January 4, 2012Date of Patent: November 4, 2014Inventors: Thomas J. Balshi, Stephen F.

Publication number: 20140295395Abstract: Paired bones are individually secured in an anatomically relevant manner onto independent, parallel positioned platforms, and configured into motorized models for the purpose of teaching and assessing clinicians' ability to identify and compare the relative positions of bony landmarks within the coronal and sagittal planes. One platform can be powered by two motors to generate precise landmark asymmetries, moving the platforms in the coronal plane and around a horizontal axis. As the platform shears upward or rotates forward, the landmarks on the bone attached to that platform can be moved superiorly compared to the other side. A central computer can instruct the motors of a plurality of models to move predetermined amounts via a two-way wireless communications link. The model can communicate back to the computer once the movement is completed, assuring a high level of precision in obtaining the intended positional asymmetry or informing the user that the move exceeds the limits of the model.Type: ApplicationFiled: March 14, 2014Publication date: October 2, 2014Inventors: Brian Degenhardt, Kenneth Pamperin
