A method of implanting a heart valve prosthesis is disclosed. A valve is mounted within a support apparatus that is deformable between an expanded and a reduced cross-sectional condition. The prosthesis can be implanted into a patient's heart, such as during a direct vision procedure through a generally tubular implantation apparatus that maintains the prosthesis in its reduced cross-sectional condition until discharged from the tubular apparatus at a desired implantation site.

Shaper for vertebral fixation rods

ActiveUS20170360493A1Reduce the cross-sectional areaIncrease flexibilityInternal osteosythesisComputer-aided planning/modellingControl systemRobot control system

A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.

A gas turbine includes a combustor liner having at least one hole formed therein. The gas turbine also includes a flow sleeve that at least partially surrounds the liner thereby forming a plenum between the flow sleeve and the liner, the plenum having an airflow therethrough, a portion of the airflow passing through the at least one hole in the liner and into the liner thereby reducing the mass of the airflow in the plenum. The flow sleeve has an axial profile that is reduced in cross section dimension at a predetermined axial location of the flow sleeve, thereby reducing a width of the plenum at the predetermined axial location. The reduction at the cross section dimension in the flow sleeve increases a velocity of the airflow in the plenum at the predetermined axial location, the increased velocity airflow increasing transfer of heat away from the liner.

A coronary stent is disclosed herein as having a lattice configuration on a generally thin-walled cylindrical tube. This particular stent is fabricated using an elongated thin-walled tubular solid that has a diameter equal to that of the final expanded configuration of the stent. In other words, the lattice configuration is cut onto the surface of the tubular solid that has a diameter substantially equal to the inner diameter of the blood vessel for which the stent is intended. The tubular lattice is then shrunk (collapsed) axisymmetrically to a new cylindrical configuration with a diameter substantially less than the blood vessel for which the stent is intended. The stent in its reduced diameter state can then be delivered to a desired site in the body via a catheter with an inflatable balloon at its distal portion. Upon the inflation of the balloon, the stent will assume its expanded, deployed configuration into the original diameter at the desired site in the body.
