Surgical procedures, tools and implants are disclosed for both conventional and reverse shoulder implant surgeries. The improved procedures, tools and implants relate to humeral head resurfacing, humeral head resection for standard implants, humeral head resection for reverse shoulder implants, glenoid resurfacing for standard shoulder implants and glenoid resurfacing for reverse shoulder implants. 3D scans and x-rays are used to develop virtual models of the patient anatomy, identify patient specific landmarks for anchoring guide wire installation blocks, templates and drill guides. 3D scans are also used to design patient specific tools and implants for the shoulder implant procedures and to pre-operatively determine the appropriate inclination and retroversion angles.

An implantable device for facilitating the healing of voids in bone, cartilage and soft tissue is disclosed. A preferred embodiment includes a cartilage region comprising a polyelectrolytic complex joined with a subchondral bone region. The cartilage region, of this embodiment, enhances the environment for chondrocytes to grow articular cartilage; while the subchondral bone region enhances the environment for cells which migrate into that region's macrostructure and which differentiate into osteoblasts. A hydrophobic barrier exists between the regions, of this embodiment. In one embodiment, the polyelectrolytic complex transforms to hydrogel, following the implant procedure.

A method, apparatus, and system, are provided for guiding a medical procedure relating to an implantable medical device operatively coupled to a cranial nerve. Communications between the implantable medical device and an external device are established. An implant procedure is performed for implanting the implantable medical device. A first diagnostic process of the implantable medical device is performed. Using the external device a first signal is received from the implantable medical device based on the first diagnostic process. A first instruction is displayed using the external device based upon the first signal received by the external device. The first instruction includes information relating to guiding the implant procedure.

Provided herein, inter alia, is a system for indicating the location of a dental drill includes a dental handpiece, which further includes the dental drill. A plurality of sensors detect a magnetic field and produce a set of outputs, which are usable at least in part to indicate the location of the dental drill. The sensor outputs may be processed to produce an indication of the spatial relationship of the drill to a patient's dentition. The indication is preferably graphical, and may be presented to a dental professional using the system during an implant procedure to provide visual feedback about the procedure. The indication may be repeatedly updated, substantially in real time.

A surgical procedure for preparing a damaged area of a human knee to receive at least one graft, according to which a moldable material is positioned over the damaged area and removed after it hardens. The mold is used as a template to determine the number and/or a dimension of the openings to be formed in the damaged area for receiving corresponding grafts.

A method for determining an effectual placement of an electrode array during a surgical procedure to implant the lead is provided. This method involves placing a lead having electrodes in a first location in a patient then (1) activating electrical stimulation to produce paresthesia, (2) “electronically trolling” the length of the electrode array and (3) determining whether the paresthesia is in an effective location. If the paresthesia is not in an effective location to match the location of the pain, the lead is moved to a different location steps (1) through (3) are repeated. The process of electronically trolling involves moving the electrical stimulation along the electrode array so that all regions of the electrode array provide stimulation. This method reduces or eliminates the need to move the lead during the implant procedure and thus simplifies the implant procedure compared to the currently used physical trolling method, reducing the risks to the patient. Additionally, this method saves time and improves outcomes by allowing multiple electrode combinations to be tested in a relatively short amount of time.

A method for preparing a surgical guide for positioning of a dental implementation. The method includes positioning a positioning device relative to a model jawbone, translating the positioning device in a BL direction, adjusting a BL angle of the positioning device about a BL pivot axis corresponding to a desired position of a top of the dental implementation, and fixing the BL position, BL angle, and z-height of the positioning device. A mounting assembly mounts to the positioning device and includes a removable rotation block with a guide hole. The mounting assembly is movable in the MD direction while the BL position is fixed. A template fixes the mounting assembly for transferring the positioning information to a patient's mouth. Various aspects of the design process can be performed on a computer. The guide and a method of using the guide to perform an implant procedure are also disclosed.

A multilayer composite vascular access graft and a method of constructing such a graft are disclosed. The mcVAG has improved performance characteristics, which include desirable handling characteristics such as ease of suturing, kink resistance and the ability to serve as a cannulation route soon after the implant procedure.

First, a substrate with a recess is provided in a semiconductor process. Second, an embedded SiGe layer is formed in the substrate. The embedded SiGe layer includes an epitaxial SiGe material which fills up the recess. Then, a pre-amorphization implant (PAI) procedure is carried out on the embedded SiGe layer to form an amorphous region. Next, a source/drain implanting procedure is carried out on the embedded SiGe layer to form a source doping region and a drain doping region. Later, a source/drain annealing procedure is carried out to form a source and a drain in the substrate. At least one of the pre-amorphization implant procedure and the source/drain implanting procedure is carried out in a cryogenic procedure below −30° C.

A method as a workflow for imaging for a heart valve implant procedure includes positioning the patient and an articulated imaging apparatus relative to one another, inducing rapid ventricular pacing in the patient, and imaging a region of the patient's heart to obtain image date for a three-dimensional image. The three-dimensional data is used to construct a three-dimensional image of the region of the patient's heart an the three-dimensional image is displayed for use in the implanting of the replacement heart valve. Optional steps may include obtaining a real time two-dimensional image of the patient's heart and superimposing the real time two-dimensional image with the constructed three dimensional image. The replacement valve is moved into position in the patient's heart during rapid ventricular pacing and breath hold using the superimposed two-dimensional and three-dimensional image information.

A bone implant apparatus and method includes a programmable device for creating a bone implant. A computer program is connected with the programmable device and the computer program includes a repository of implant programs for standard bones and spacers of preselected dimensions and forms and where the repository of implant programs are customizable and where the bone implant includes a fixation point.

A surgical instrument suitable for use in an implant procedure is disclosed. A surgical instrument of the invention can be particularly advantageous for use in grasping, holding and placement of implants in an intervertebral disc space. In a typical embodiment, the surgical instrument has a grasping region to hold the implant, and an impact head for receiving a force in order to insert the implant.

The present invention is a tool to measure depth and width of bone cavities prior to and during oral implant placement. The tool includes a passive-depth gauge arm and an active spring caliper arm. The tool can be used to define the extraction socket for oral implant placement and allows measurement verifications after each step of the bone bed preparation prior to or during the actual implant placement in the extraction socket. There are multiple modifications of the primary design into separate embodiments to accommodate usage in different parts of the jaw and different points during the implant procedure.
