Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. Once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed. Using the teaching of the present disclosure, a surgeon can customize a fastener to the particular surgery or even to the particular portion of surgery being performed during the surgery.

An ultrasound imaging probe for real time 3D ultrasound imaging from the tip of the probe that can be inserted into the body. The ultrasound beam is electronically scanned within a 2D azimuth plane with a linear array, and scanning in the elevation direction at right angle to the azimuth plane is obtained by mechanical movement of the array. The mechanical movement is either achieved by rotation of the array through a flexible wire, or through wobbling of the array, for example through hydraulic actuation. The probe can be made both flexible and stiff, where the flexible embodiment is particularly interesting for catheter imaging in the heart and vessels, and the stiff embodiment has applications in minimal invasive surgery and other procedures. The probe design allows for low cost manufacturing which allows factory sterilized probes to be disposed after use.

A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention component whose primary functions are to prevent migration of the load bearing device and loss or migration of graft material from within the load bearing device. A secondary function of the retention component is to address fixation of fasteners when the surgeon is confronted with a challenging access to adequate boney structures due to excessive curvature / angulation of the vertebrae column, minimal invasive surgery techniques, danger to surrounding vascular or neurological tissues, poor bone quality, or similar surgical complications. A tertiary function of the retention component is to provide better alignment and stabilization of misaligned vertebrae when spondylolisthesis is a significant factor. One or more fasteners secure the retention component to each of the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion.
