Abstract
An implantable pump (10) is provided for pumping a drug in a patient's body (100). The pump includes a drug delivery chamber (22) configured to be filled with the drug and a drug delivery catheter (50) having a catheter lumen (58) and a distal end (56), the drug delivery catheter in fluid communication with the drug delivery chamber and configured to deliver the drug to a delivery site (102). It also includes a pushing element (44) coupled to the distal end of the catheter, and configured to push away from the catheter lumen fibrotic matter that has developed in response to the drug delivery catheter. Other embodiments are also described.
Claims26
An implantable pump for pumping a drug in a patient's body, comprising:
- a drug delivery chamber configured to be filled with the drug;
- a drug delivery catheter having a catheter lumen and a distal end, the drug delivery catheter in fluid communication with the drug delivery chamber and configured to deliver the drug to a delivery site;
- and
- a pushing element coupled to the distal end of the catheter, and configured to push away from the catheter lumen fibrotic matter that has developed in response to the drug delivery catheter.
The pump according to 11, wherein the input device comprises a push button.
A method for operating an implantable drug pump implanted in a patient's body, comprising:
- initiating delivery of a bolus of a drug to a delivery site within the patient's body;
- and
- pushing away fibrotic matter that has developed in response to the drug pump.
An implantable drug pump for implantation in a patient's body comprising:
- a drug delivery chamber adapted to be filled with a drug to be delivered to a drug delivery site in the patient's body;
- a drug delivery catheter having a catheter lumen and extending from the drug delivery chamber to a delivery catheter distal end that is adapted to be disposed in the patient's body and that is prone to fibrin buildup;
- means for initiating delivery of a bolus of the drug from the drug delivery chamber through the catheter lumen to the delivery site;
- and
- means for pushing a fibrin buildup away from the delivery catheter distal end.
