摘要： A thrombolysis catheter apparatus is disclosed comprising: (a) an elongated thrombolysis catheter portion comprising a plurality of independently controllable electroactive polymer actuators, which provide a curvature to the thrombolysis catheter based upon received control signals; (b) a control unit coupled to the plurality of actuators and sending the control signals to the plurality of actuators; and (c) an occlusion removal device. Also disclosed is a method of treating an arterial occlusion by advancing the thrombolysis catheter portion through the arterial vasculature of a patient to a position proximate the occlusion, while controlling the shape of the thrombolysis catheter portion using the control unit. The occlusion is then removed using the occlusion removal device.

摘要： The present invention is directed to a drug delivery pump apparatus, which comprises: (a) an expandable and contractible enclosure having an interior volume that defines a medication reservoir; (b) one or more electroactive polymer actuators; (c) a medication outlet port providing fluid communication between the interior volume of the contractible and expandable enclosure and an exterior of the delivery pump apparatus; and (d) a control unit electrically coupled to the one or more actuators and sending control signals to the same. The one or more electroactive polymer actuators act to reduce the interior volume of the contractible and expandable enclosure based upon the received control signals. The present invention is also directed to a method of delivering a liquid therapeutic agent to a patient. The method comprises: (a) providing the above infusion pump apparatus; (b) placing the outlet port of the infusion pump apparatus in fluid communication with a patient; and (c) sending the control signals to the one or more actuators to reduce the internal volume of the contractible and expandable enclosure, thereby forcing a portion of the liquid therapeutic agent within the medication reservoir through the outlet port and into the patient
