Abstract
A cardiac rhythm management (CRM) system includes an implantable medical device that delivers combined electrical and drug therapies. The implantable medical device includes a drug reservoir that is refillable after implantation. In one embodiment, the implantable medical device includes an implantable housing encapsulating a pulse generator circuit and a drug delivery device. In another embodiment, the implantable medical device includes an implantable pulse generator and an implantable drug delivery device fastened to each other.
Claims46
A cardiac rhythm management (CRM) system, comprising:
- an implantable medical device including:
- a pulse output circuit to deliver electrical pulses;
- a drug delivery device including:
- a drug reservoir to contain a drug;
- and
- a reservoir filling port connected to the drug reservoir;
- an implant controller, coupled to the pulse output circuit and the drug delivery device, to control delivery of the electrical pulses and the drug;
- and
- an implantable housing to contain the pulse output circuit, the drug delivery device, and the implant controller,
- wherein the reservoir filling port is constructed on the implantable housing and includes a self-resealable portion adapted to allow filling of the drug reservoir using a hollow needle.
A cardiac rhythm management (CRM) system, comprising:
- an implantable pulse generator to deliver electrical pulses, the implantable pulse generator including:
- a pulse generator circuit;
- and
- a first implantable housing configured to encapsulate the pulse generator circuit;
- and
- an implantable drug delivery device to deliver a drug, the implantable drug delivery device including:
- a drug reservoir to contain the drug;
- a second implantable housing configured to encapsulate portions of a structure of the implantable drug delivery device including the drug reservoir, the second implantable housing fastened to the first implantable housing;
- and
- a reservoir filling port constructed on the second implantable housing, the reservoir filling port including a self-resealable portion adapted to allow filling of the drug reservoir through a hollow needle.
A medical device assembly, comprising:
- an implantable drug delivery device including:
- a drug reservoir to contain the drug;
- an implantable housing adapted to contain portions of a structure of the implantable drug delivery device including the drug reservoir, the implantable housing configured to be attached to an implantable cardiac rhythm management (CRM) device;
- and
- a reservoir filling port constructed on the implantable housing, the reservoir filling port including a self-resealable portion adapted to allow filling of the drug reservoir using a hollow needle;
- and
- means for fastening the implantable drug delivering device to the implantable CRM device.
A method for making an implantable cardiac rhythm management (CRM) system, comprising:
- providing a pulse generator circuit adapted to deliver electrical pulses to one or more electrodes;
- providing a drug delivery device including a drug reservoir;
- encapsulating the pulse generator circuit and the drug delivery device using an implantable housing;
- and
- incorporating a self-resealable reservoir filling port onto the implantable housing to allow filling of the drug reservoir using a hollow needle.
A method for making an implantable medical device, comprising:
- providing an implantable pulse generator including an implantable pulse generator housing;
- providing an implantable drug delivery device including a drug reservoir, an implantable drug delivery device housing, and a self-resealable reservoir filling port constructed on the implantable drug delivery device housing to allow filling of the drug reservoir using a hollow needle;
- and
