摘要： An atherectomy system includes a drive assembly and an advancer assembly. The drive assembly, which may be reusable, includes a drive motor having an output shaft and a first coupler segment that is secured relative to the output shaft. A controller may be adapted to regulate operation of the drive motor. The advancer assembly, which may be single use, includes a flexible drive cable that is adapted to be releasably securable to the first coupler segment. The advancer assembly includes gearing that is secured within the advancer assembly and is operably coupled with the flexible drive cable. A burr catheter is coupled with and extends distally of the gearing. The advancer assembly is adapted to enable relative translation of the burr catheter in order to advance and withdraw an atherectomy burr rotatably secured to a distal end of the burr catheter.

摘要： An inflatable penile prosthesis can comprise a reservoir, an inflatable member, and a pump assembly. The pump assembly can include at least one valve comprising an entry tube interface configured to attach to the entry tube and defining an entry passageway, an entry portion adjacent to the entry tube interface, a middle portion adjacent to the entry portion, an exit portion adjacent to the middle portion, the exit portion being narrower than the middle portion, the exit portion defining an exit portion passageway and comprising multiple guides extending toward a longitudinal exit axis, the multiple guides being symmetrical about the longitudinal exit axis, the exit tube interface adjacent to the exit portion, and a poppet disposed inside the chamber, the poppet being biased to rest against the entry portion.

摘要： A percutaneous circulatory support device includes a housing and an impeller disposed within the housing. The impeller is configured to rotate relative to the housing to cause blood to flow through the housing. A motor is operably coupled to the impeller, and the motor is configured to rotate the impeller relative to the housing. A catheter is coupled to the motor. A collar is coupled to the catheter and disposed proximally relative to the housing. The collar includes an internal chamber, and pressure sensor is disposed within the internal chamber of the collar.

摘要： A medical device for tissue ablation may include a catheter shaft, an expandable member disposed on or coupled to the catheter shaft, and a plurality of elongate electrode assemblies each constructed as a flexible circuit. The expandable member may be configured to shift between an unexpanded configuration and an expanded configuration. The plurality of electrode assemblies may be disposed on an outer surface of the expandable member. Each of the plurality of electrode assemblies may include a temperature sensor aligned with two or more electrodes.
