A catheter pump system with a pump having a fluid displacement member in the blood flow channel, a motor and a motor controller having a pressure sensing port for connection to a control pressure source. The motor controller is arranged for causing motor speed to be increased in response to a reduction of pressure applied to the pressure sensing port and for causing motor speed to be reduced in response to an increase of pressure applied to the pressure sensing port. The motor may be a pneumatic motor for driving the pump and the motor controller may be arranged for controlling motor speed by reducing flow through a supply channel to the motor and allowing an increase of flow through the supply channel to the motor in response to control signals received via an input interface.

Catheter pump system and method of controlling a catheter pump drive

A pressure actuated single-lumen blood pumping device has a housing () having a wall () bounding a pressure transfer chamber (). The housing () bounds a pressure transfer port () for connection to a pressure source, the pressure transfer port () communicating with the pressure transfer chamber () for alternatingly transferring over pressure and under pressure from the pressure source to the pressure transfer chamber (). A flexible tubular membrane () is arranged in the pressure transfer chamber (). A blood transfer conduit () passes through the wall () bounding the pressure transfer chamber () and the blood transfer conduit () connects to opposite ends () of the flexible tubular membrane ().

Pressure actuated single-lumen blood pumping device

The present invention provides an intermediate attachment mechanism, called a powerposer (), which includes at least one power source () coupled to an integrated circuit (), at least one integrated circuit, which is arranged to store a code comprising information and powered with energy provided by the power source and a substrate () on which the at least one power source and the at least one integrated circuit are disposed, and wherein the substrate comprises connection means () for connecting to an application device and attachment means for attaching to the application device. Further, the present invention provides a battery assisted or active RFID transponder featuring a transponder substrate, at least one antenna disposed on the transponder substrate and a powerposer disposed on the transponder substrate. Still further the present invention provides methods of production of a powerposer and an active or battery assisted RFID transponder comprising a powerposer.
