Implantable fluid delivery system with floating mass transducer driven pump

摘要

An implantable fluid delivery system for use in hearing systems includes an implantable fluid pump having a fluid chamber having at least one wall with a membrane, an inlet and an outlet in fluid communication with the fluid chamber, and a floating mass transducer coupled to the membrane. The membrane is configured to move in a first direction increasing a volume of the fluid chamber and to move in a second direction decreasing the volume of the fluid chamber, and the floating mass transducer is configured to cause the membrane to move in the first and second directions. The system further includes an implantable hearing device having one or more fluid channels in fluid communication with the fluid pump.

1. An implantable fluid delivery system for use of a treatment of an ear, the system comprising:
an implantable fluid pump comprising:
a first fluid chamber and a second fluid chamber separated by a membrane, the membrane configured to move in a first direction increasing a volume of the first fluid chamber while decreasing a volume of the second fluid chamber, and configured to move in the second direction decreasing the volume of the first fluid chamber while increasing the volume of the second fluid chamber;a first inlet and a first outlet in fluid communication with the first fluid chamber;a second inlet and a second outlet in fluid communication with the second fluid chamber; anda floating mass transducer coupled to the membrane and configured to cause the membrane to move in the first and second directions; a first reservoir in fluid communication with the first fluid chamber; a second reservoir in fluid communication with the second fluid chamber; and an implantable hearing device having one or more fluid channels in fluid communication with the first fluid chamber and the second fluid chamber.
