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.

Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve / holder subassembly. The packaging system facilitates attachment of the valve delivery tube for use in a quick-connect valve implant procedure.

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.

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.

Transrectal ultrasound guided transperineal low dose-rate brachytherapy has been emerged as one of the definitive treatments of low-risk prostate cancer. Ultrasound has been an excellent tool in guiding the implant needles with respect to prostate anatomy, yet it cannot show reliably the location of radioactive seeds after they are released in the prostate. Intraoperative C-arm fluoroscopy can show the implanted seeds, but it cannot detect prostate anatomy. Intra-operative fusion of these two complementary modalities offers significant clinical benefit by allowing for real-time optimization of the brachytherapy implant as the procedure progresses in the operating room. Disclosed is a system and method for mitigating this problem and providing registration of seeds seen by fluoroscopy with live prostate anatomy visualized by transrectal ultrasound.

A dental implant management system / method that improves communication and coordination between parties associated with dental implant procedures is disclosed. The system / method operates to permit each dental implant professional (DIP) (typically a surgeon, restorative doctor, and dental laboratory) to iteratively generate a patient treatment execution plan (TEP) for the dental implant procedure that is generally structured within execution treatment phases (ETP) and automatically coordinated among each DIP. The ETP typically defines FOUNDATION, IMPLANT PLACEMENT, RESTORATIVE, and MAINTENANCE phases that may each incorporate custom execution phase checklists (EPC) that permit each DIP to ensure that critical elements of their TEP are properly executed. Coordination of the various DIP-generated TEPs is integrated with treatment planning / sequencing, patient scheduling, DIP fee estimation, and dental parts procurement to ensure maximum revenue to each DIP while simultaneously improving the probability of a successful dental implant procedure for the patient.

The present invention generally relates to a method of using a matrix as a barrier for unwanted cell attachment and bone formation in unwanted areas of the human body during implant procedures. More specifically, a growth-inhibiting matrix may be used to prevent migration of osteo-inductive agents or bone tissue from an intervertebral disc space through the outer bands of annulus fibrosis that abuts the spinal tissue, canal, and other surrounding areas.

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.
