Abstract: 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.

Abstract: 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.

Abstract: A bearing assembly is configured to retain a distal end of an impeller of a blood pump, where the impeller includes a drive shaft. The bearing assembly includes a pivot member coupled to a distal end of the drive shaft; a distal bearing cup having a proximally-facing surface configured to engage at least a portion of a distal section of the pivot member; and a sleeve bearing disposed around at least a portion of a proximal section of the pivot member.

Abstract: A bearing assembly is configured to retain an end of an impeller of a blood pump and includes a thrust plate having a distal-facing surface and an impeller bearing surface configured to be disposed adjacent the distal-facing surface such that a gap is defined between the distal-facing surface of the thrust plate and the impeller bearing surface. The impeller bearing surface includes at least one washout blade disposed thereon and configured to facilitate blood flow through the gap.

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.

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.
