Pericardial delivery of treatment
First Claim
1. An implantable cardiac therapeutic device comprising:
- a lead configured for at least partial placement in a pericardial space;
at least one implantable sensor on the lead and arranged to sense at least one physiologic characteristic of a patient;
an implantable therapeutic agent delivery assembly entirely on the lead, the delivery assembly including a structure for holding a therapeutic agent for subsequent delivery, an agent delivery dispenser coupled to the structure by a conduit and configured to deliver the agent to a target tissue, and a pressure source configured to provide pressure to the structure to induce flow of the agent from the structure to the agent delivery dispenser, wherein at least a portion of the delivery assembly is configured for placement in the pericardial space and the agent is entirely contained within the structure that is entirely on the lead; and
an implantable controller configured to be connected with the lead so as to be in electrical communication with the at least one implantable sensor and with the therapeutic agent delivery assembly wherein the controller evaluates the at least one physiologic characteristic for indications of a condition indicating administration of the therapeutic agent and wherein, upon detection of such indications, induces the therapeutic agent delivery assembly to deliver the agent.

Abstract
An implantable cardiac therapeutic device having at least one implantable sensor arranged to sense at least one physiologic characteristic of a patient, an implantable therapeutic agent delivery assembly wherein the delivery assembly and a therapeutic agent to be delivered are configured for placement in a patient'"'"'s pericardial space, and a controller in communication with the at least one implantable sensor and with the therapeutic agent delivery assembly wherein the controller evaluates the at least one physiologic characteristic for indications of a condition indicating administration of the therapeutic agent and wherein, upon detection of such indications, induces the therapeutic agent delivery assembly to deliver the agent. Also an implantable patient lead adapted for connection to a separable implantable therapy device, the lead including an implantable therapeutic agent delivery assembly wherein the delivery assembly and a therapeutic agent to be delivered are configured for placement in a patient'"'"'s pericardial space.

15. An implantable patient lead comprising:
-
a lead body having a distal end region configured for placement in a pericardial space; a connector at a proximal end of the lead body adapted for connection to an implantable therapy device; an implantable therapeutic agent delivery assembly entirely on the distal end region of the lead body, the delivery assembly including a structure for holding a therapeutic agent for subsequent delivery, an agent delivery dispenser coupled to the structure by a conduit and configured to deliver the agent to a target tissue, and a pressure source configured to provide pressure to the structure to induce flow of the agent from the structure to the agent delivery dispenser, wherein the delivery assembly is configured for placement in the pericardial space and the agent is entirely contained within the structure that is entirely on the lead; and one or more contacts on the connector, the one or more contacts in electrical contact with the therapeutic agent delivery assembly. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
