  • Publication number: 20220175532
    Abstract: According to an aspect, an inflatable penile prosthesis includes a reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to facilitate a transfer of a fluid from the reservoir to the inflatable member. The pump assembly includes a pump bulb, and a valve body defining a fluid passageway. The valve body includes a refill valve disposed in the fluid passageway. The refill valve includes a valve member. In response to the pump bulb being compressed, the valve member moves within the fluid passageway in a first direction to a closed position in which the valve member blocks the fluid from being transferred around the refill valve. In response to the pump bulb being uncompressed, the valve member moves within the fluid passageway in a second direction to an open position in which the valve member allows the fluid to transfer around the refill valve.

  • Publication number: 20220133347
    Abstract: An atherectomy system includes an atherectomy burr having one or more blood flow enhancement features that permit an increased level of blood flow past the burr relative to a blood flow that would result absent the one or more flow enhancement features. A drive mechanism is adapted to rotatably actuate the atherectomy burr.

  • Publication number: 20140336637
    Abstract: A medical system configured for nerve modulation can include an elongate shaft, having a distal end region and a proximal end region is disclosed. Adjacent the distal end region an ablation electrode can be disposed. The system can further include a first optical fiber, having a proximal end and a distal end, extending along an outer surface of the elongate shaft, and in turn a number of (fiber Bragg Grating) FBG sensors therein. The FBG sensors can be positioned adjacent to the ablation electrode. An optical read out mechanism can be optically coupled to the optical fiber to transmit light into the optical fiber and detect light reflected from the FBG sensor. Here, the detected light, reflected from FBG temperature sensors, encodes local temperatures at each of the FBG temperature sensors.
