20090076551 | METHODS AND SURGICAL KITS FOR MINIMALLY-INVASIVE FACET JOINT FUSION - Disclosed herein are methods and surgical kits that can be used to fuse facet joints via a minimally invasive procedure (including an arthroscopic or percutaneous procedure). An exemplary method includes creating an incision; locating a facet joint with a distal end of a pin; sliding a substantially hollow drill guide over said pin wherein said drill guide comprises a proximal end, a distal end; removing said pin from within said drill guide; inserting a drill bit into said drill guide; drilling a hole into a bone of said facet joint; removing said drill bit; inserting a facet joint bone plug into said hole using a bone plug inserter having a raised portion at or near is proximal end, wherein said raised portion prevents over-insertion of said bone plug; and removing said drill guide. | 03-19-2009 |
20090182377 | IMPLANT DEVICE USED IN MINIMALLY INVASIVE FACET JOINT HEMI-ARTHROPLASTY - A metallic inverted L-shaped implant is used to resurface the superior facet of the inferior vertebrae limited to the facet joints located on the spine, Occiput-C1 through L5-S1. The metallic implant is highly polished on its exterior and textured on its interior surface. It is mechanically crimped in place without the use of cement or pedicle screws. Permanent fixation occurs when bone in-grows onto a rough, porous surface on the inside of the implant. The implant employed in a hemi-arthroplasty method resurfaces half of the facet joint to provide for smooth, pain free joint articulation in deteriorated or diseased spinal facet joints without the need for major surgery or rehabilitation at considerably less risk to the patient. | 07-16-2009 |
20100222829 | SPINAL PLUG FOR A MINIMALLY INVASIVE JOINT FUSION SYSTEM - A frustum shaped body has an aperture in a top surface and a pair of first and second opposed apertures in a side surface, first and second horizontal internal channels connect both the first and second opposed apertures. A vertical channel from the top aperture connects with the first and second channels. After the body is inserted into a hole in a facet joint, compatible synthetic or biologic material is inserted into the vertical channel until the material exits from the first and second apertures in the side surface. At least one pair of flanges on a portion of an exterior side surface of the body acts as a detent to hold the body in place within the facet joint hole. | 09-02-2010 |
20100268228 | SURGICAL METHODS AND TOOLS - The present invention relates generally to tools, tool kits and methods useful for treating an SI joint. In one embodiment, the present invention is a. In one embodiment, the present invention is a method including the steps of: implanting a graft into a SI joint of a patient, wherein the implanting comprises: creating an incision in the patient's skin proximal to the patient's SI joint; dilating the incision; creating a void in the SI joint, wherein the creating comprises displacing a portion of the patient's ilium and a portion of the patient's sacrum; and inserting a graft into the void in the SI joint, wherein the graft contacts the patient's iluim and the patient's sacrum and wherein the graft is configured to substantially fuse the patient's ilium to the patient's sacrum, thereby substantially immobilizing the patient's SI joint. | 10-21-2010 |

20090007414 | SCALABLE ULTRASOUND SYSTEM AND METHODS - A plurality of application specific integrated circuit (ASIC) chips with different functions is provided. Each of the ASICs performs one or more functions along an ultrasound data path. The chips include communications protocols or processes for allowing scaling. For example, ASICs for backend processing include data exchange ports for communicating between other ASICs of the same type. As another example, receive beamformer ASICs cascade for beamformation. By providing ASICs implementing many or most of the ultrasound data path functions, with scalability, the same ASICs may be used for different system designs. A family of systems from high end to low-end using the same types of ASICs, but in different configurations, is provided. | 01-08-2009 |
20090015101 | Embedded circuits on an ultrasound transducer and method of manufacture - One or more chips, integrated circuits, or semiconductors are embedded within a backing block. Planar sheets of backing material are formed with integrated circuits within holes in the sheets. Traces connect the integrated circuit to electrodes or exposed conductive surfaces. A plurality of the planar sheets may be manufactured using wafer processing, such as pick and place of chips in a wafer of backing material and IC redistribution for forming the traces. The different sheets are cut from the wafer and stacked adjacent each other. The transducer connects with the exposed electrodes or conductive surfaces of the backing. | 01-15-2009 |
20090093720 | RECEIVE CIRCUIT FOR MINIMIZING CHANNELS IN ULTRASOUND IMAGING - Receive circuits and associated methods are provided for ultrasound imaging. Both subarray mixing and time division multiplexing are provided with a same circuit. Components of the receive circuit respond to either phasing or time slot information to implement subarray mixing or time division multiplexing. A network of switches allows combination of signals from different elements to form different sub-apertures. A controller minimizes power consumption while outputting the desired phase or time division multiplexed information by gating a clock to various registers. Each of the registers corresponds to different groups of transducer elements. For loading new phasing information, the clock is turned on to the desired register. Duration operation of the receive circuit, the clock is gated off. The register outputs the previously loaded values in a static state without clocking. Preamplification for either of time division or subarray mixed signals is provided using a variable gain amplifier with a common mode feedback. The common mode feedback provides for a constant operating point despite changes in the desired amount of gain. | 04-09-2009 |

The modules allow the same electronics parts to be used with different sized arrays. The traces and pads of the flexible circuit material may be changed for different arrays without having to redesign the electronics and/or modules. | 10-25-2012 |
