Abstract
An implantable microbolus infusion pump is disclosed which includes an elastically deformable reservoir, an electrically activated microvalve, and a remotely activated control system. The control system includes a sensor that can be remotely activate, for example, magnetically or by infrared light. The pump can provide bolus infusion of pharmacologic agents. The pump is also capable of providing sequential release of a plurality of drugs.
Claims25
An implantable pump for delivery of a drug, the implantable pump comprising:
- a reservoir that deforms elastically when it is filled with the drug;
- an outlet catheter in fluid communication with said reservoir;
- a valve in fluid communication with said outlet catheter, wherein said valve is electrically activated;
- and
- a control system comprising a sensor, wherein said sensor generates a control signal for controlling said valve when electromagnetic radiation interacts with said sensor.
An implantable pump for drug delivery comprising:
- a reservoir having an elastically deformable member and a substantially rigid backing member;
- a solenoid valve in fluid communication with said outlet catheter, wherein said valve has a closed resting position;
- an outlet catheter in fluid communication with said valve;
- and a control system having an infrared sensor and an electronic circuit controlling said valve.
An implantable pump for delivery of a drug, the implantable pump comprising:
- a reservoir that deforms elastically when it is filled with the drug;
- an outlet catheter in fluid communication with said reservoir;
- a valve in fluid communication with said outlet catheter, wherein said valve is electrically activated;
- a source of infrared radiation;
- a control system comprising a sensor for detecting infrared radiation from said source, wherein said sensor generates a control signal for controlling said valve when said sensor detects infrared radiation.
