A catheter includes a catheter body, a pump assembly and a cannula. The pump assembly can be disposed at a distal end of the catheter body and has a distal portion. The cannula can be coupled to the distal end portion of the pump assembly and can include a proximal cannula portion and a distal cannula portion. The distal cannula portion has an approximately helical shape which can allow the cannula to be inserted into a patient's right heart and pump blood therethrough. In certain implementations, the distal tip of the helical shape has a slight bias relative to the main helix to further facilitate delivery of the device. In certain applications this bias is toward the central axis of the helix.

Distal extension for a blood pump system

A cannula supporting a percutaneous pump can include a proximal section with a first flexural modulus. The cannula can include one or more distal sections with a flexural modulus that is different than the first flexural modulus. The material and its arrangement along the length of the cannula can be selected so as to influence bending properties. This can, for example, allow efficient positioning of the cannula in a desired location without displacing the guidewire.
