    Abstract: A circuit for generating a radio-frequency signal for a surgical device is disclosed. The circuit has a voltage regulator that supplies direct current (DC) voltage, a first MOSFET, a second MOSFET, and a MOSFET driver. The MOSFET driver receives the DC voltage supplied from the voltage regulator and has a local oscillator. The local oscillator switches the first MOSFET and the second MOSFET on and off at a frequency generated by the local oscillator. The circuit further includes a transformer connected to the first and second MOSFETs, having a center tap and a main voltage applied at the center tap, and providing an alternating current (AC) output.

  • Patent number: 9827093
    Abstract: A method for implanting a stent includes contracting a self-expanding/forcibly-expanding stent of a shape-memory material set to a given shape to a reduced implantation size with a delivery system having drive wires. The stent has a selectively adjustable assembly with adjustable elements operatively connected to the drive wires such that, when the adjustable elements are adjusted by the drive wires, a configuration change in at least a portion of the self-expanding stent occurs. The contracted stent is inserted into a native annulus in which the stent is to be implanted. The drive wires are rotated with the delivery system to forcibly expand the stent into the native annulus. While rotating the drive wires, a torque applied to the drive wires is determined with the delivery system. Rotation of the drive wires is stopped based upon a value of the determined torque.

  • Patent number: 9814611
    Abstract: Sealable and repositionable implant devices are provided to increase the ability of endovascular grafts and valves to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes a self-expanding stent of a shape-memory material set to a given shape. The stent has a wall with a portion having a first thickness and a second portion having a thickness greater than the first. The second portion defines a key-hole shaped longitudinal drive orifice. The implant includes a selectively adjustable assembly having adjustable elements and being operable to force a configuration change in at least a portion of the self-expanding stent. The adjustable elements have a part rotatably disposed within the longitudinal drive orifice.

  • Patent number: 9814372
    Abstract: A torque-transmitting, variably-flexible, locking insertion device includes a hollow body having a proximal end with an entrance for receiving an instrument, a distal end with a tip for protrusion of the instrument, and a handle to be gripped by an operator. A device locks the handle to and unlocks the handle from the instrument, which is at least partly disposed within the hollow body. A device transitions the hollow body between a relatively flexible condition and a relatively stiff condition. A method for operating a torque-transmitting, locking insertion device includes placing the instrument at least partly within the hollow body and locking the handle to and unlocking the handle from the instrument. The hollow body is transitioned between a relatively flexible condition and a relatively stiff condition.
