Abstract

A catheter system comprises a catheter comprising a distal portion, a proximal portion and an inner shaft. The inner shaft comprises a medical device receiving region for receiving and carrying a medical device. The retaining device is at least partially constructed of an electroactive polymer. The retaining device is located on or adjacent to the medical device receiving region. The electroactive polymer of the retaining device has an activated state and an inactivated state. The retaining device is capable of retaining a medical device to the catheter and releasing the medical device from the catheter by transitioning between the activated state and the inactivated state.
