An exemplary catheter includes a catheter body, a first conductive member comprising a first material positioned on the catheter body, a second conductive member comprising a second material different from the first material positioned on the catheter body, one or more electrical joints configured to electrically couple the first conductive member to the second conductive member, and one or more shock wave emitters. Each shock wave emitter is configured to generate a shock wave, and at least one shock wave emitter of the one or more shock wave emitters comprises electrodes separated by a spark gap, wherein at least one of the electrodes is formed from the second conductive member.

Systems, devices, and methods for shock wave generation utilizing catheters with multi-metal joints

A shock wave catheter for treating a lesion in a body lumen includes a shock wave emitter assembly and a retractable enclosure. In a first configuration of the catheter, the retractable enclosure is sealed to a distal member of the catheter and the lesion is treated by shock waves propagating through the enclosure wall. In a second configuration of the catheter, the retractable enclosure is retracted from the distal member of the catheter and the lesion is treated directly by shock waves emitted from the shock wave emitter assembly.

Shock wave catheter with retractable enclosure

An exemplary shock wave catheter system comprises: a catheter body comprising a lumen; an emitter wire configured to generate shock waves, wherein one or more gaps are formed between two or more portions of the emitter wire along a length of the catheter body, each of the one or more gaps forming a locus emitter; a carrier wire configured to conduct electricity to the emitter wire; and one or more electrical joints configured to electrically couple and join the emitter wire and the carrier wire.

Locus emitter shock wave catheter devices with increased longevity and higher sonic output

Various shock wave catheters and methods of use thereof that do not utilize a guidewire are described herein. The shock wave catheters include at least one shock wave emitter disposed within a distal portion of the shock wave catheter and configured to generate shock waves. The ends of conductive wires extending within an elongate tube can form the shock wave emitter(s). The shock wave emitter(s) can be surrounded by an enclosure fillable with a conductive fluid delivered by the lumen of the elongate tube. The elongate tube can include a coil or slits therein that enable flexibility of the shock wave catheter, which, in combination with the narrow profile of the shock wave catheters described herein, enable their use in navigating and treating small, tortuous vessels.

The invention relates to a mechanism that can be integrated with silicon facial prostheses used to recapitulate a natural facial appearance through biomimetic actuation. The prosthetic eye comprises a servo motor, microcontroller, battery, rotational shaft, and customized stainless steel tarsus. The tarsus mimics the natural eyelid and reinforces the silicon lid for rotational blink motion. A stainless steel clip holds the device together and polyurethane foam encases the device to allow proper fitting in the orbital cavity. The present invention fits within a model orbital cavity and the generated blink motion is tunable to match the position profile of an in vivo blink.
