20100063568 | IMPLANTABLE ELECTRODE ARRAY ASSEMBLY WITH EXTRACTION SLEEVE/TETHER - An implantable electrode array including a carrier on which plural electrodes are disposed. Also disposed on the carrier is an array antenna over which signals are wirelessly received. A tether is connected to the carrier. A tether antenna is attached to the tether. After the electrode array is implanted, during a trial period instructions and power are transmitted to the array antenna over the tether antenna. If the trial is successful, the tether is disconnected from the electrode array. If the trial is not successful and extraction of the array is necessary, extraction is accomplished by pulling on the tether. Electrode array removal may be facilitated by the pulling of the array into an extraction tube disposed over the tether. | 03-11-2010 |
20110077660 | FOLDABLE, IMPLANTABLE ELECTRODE ASSEMBLY AND TOOL FOR IMPLANTING SAME - An electrode array assembly with a frame that is foldable or bendable on which electrodes are disposed. The frame includes laterally spaced apart bridges. Tabs extend laterally outwardly from the bridges Electrodes are disposed on the tabs. Beams, also part of the frame, extend between the laterally adjacent bridges. The frame can be folded around the beams so as to cause the laterally spaced bridges to at least partially overlap. When the beams are so bent, the electrode carrying tabs extend beyond the bent beams. | 03-31-2011 |

20130060278 | SURGICAL INSTRUMENT INCLUDING HOUSING, A CUTTING ACCESSORY THAT EXTENDS FROM THE HOUSING AND ACTUATORS THAT ESTABLISH THE POSITION OF THE CUTTING ACCESSORY RELATIVE TO THE HOUSING - An instrument for treating tissue during a medical procedure includes a hand-held portion and a working portion. The hand-held portion is manually supported and moved by a user and the working portion is movably coupled to the hand-held portion. A tracking device is attached to the hand-held portion for tracking the instrument. The tracking device is in communication with a control system, which is used to keep the working portion within or outside of a boundary. A plurality of actuators are operatively coupled to the working portion. The control system instructs the actuators to move the working portion relative to the hand-held portion during the medical procedure in order to maintain a desired relationship between the working portion and the boundary. | 03-07-2013 |
20130066180 | SYSTEM OF IMPLANTABLE MEDICAL DEVICES INCLUDING A PLURALITY OF SPACED APART DEVICES AND A COMMON BUS OVER WHICH POWER AND OPERATING INSTRUCTIONS ARE DISTRIBUTED TO THE DEVICES - A system implantable components ( | 03-14-2013 |
20140260676 | Sensor Assembly and Method for Measuring Forces and Torques - A sensor assembly comprises a base plate and a sensor member displaceable relative to the base plate. A spring arrangement operates in first and second stages in response to displacement of the sensor member relative to the base plate. Different resolutions of force and torque measurements are associated with the first and second stages. A light sensitive transducer senses displacement of the sensor member relative to the base plate and generates corresponding output signals. A collimator directs a plurality of light beams onto the light sensitive transducer so that the light beams strike different pixels of the light sensitive transducer to sense displacement of the sensor member relative to the base plate. | 09-18-2014 |
20140316412 | Method of Performing a Minimally Invasive Procedure on a Hip Joint of a Patient to Relieve Femoral Acetabular Impingement - A method of performing a minimally invasive procedure on a hip joint of a patient to relieve a femoral acetabular impingement. An access device is placed through skin of the patient to provide minimally invasive access to a target volume of material that creates the femoral acetabular impingement. A cutting accessory is placed into the access device to remove material and relieve the femoral acetabular impingement. A tracking and control system establishes a virtual boundary that defines the target volume of material that creates the femoral acetabular impingement, tracks a position of the cutting accessory relative to the virtual boundary, and controls movement of the cutting accessory so that cutting is substantially maintained within the virtual boundary. | 10-23-2014 |
20150094734 | ELECTRODE ARRAY AND DEPLOYMENT ASSEMBLY INCLUDING AN ELECTRODE ARRAY THAT IS FOLDED INTO A CANNULA THAT IS NARROWER IN WIDTH THAN THE ARRAY - An electrode array assembly with a frame that is foldable or bendable on which electrodes are disposed. The frame includes laterally spaced apart bridges. Tabs extend laterally outwardly from the bridges Electrodes are disposed on the tabs. Beams, also part of the frame, extend between the laterally adjacent bridges. The frame can be folded around the beams so as to cause the laterally spaced bridges to at least partially overlap. When the beams are so bent, the electrode array can be disposed in an access cannula that has a diameter less than the width of the unfolded array. | 04-02-2015 |
