Catheter device

摘要

The device (1) has a motor (7) located at a proximal end area of the device by a magnetic coupler (9). A pump head (3) is connected with a drive shaft (4) that extends from the proximal end area to a distal end area. A catheter shaft i.e. polyurethane tube, extends from the proximal to distal areas. The coupler is provided with proximal and distal magnet units that are connected to the motor and the drive shaft, respectively. The distal unit is mounted in a coupler housing in a leak-tight manner. A proximal end of the catheter shaft is connected to the housing in a leak-tight manner. An independent claim is also included for a method for operating a catheter device.
