Cardiac Biosensor Devices and Methods
First Claim
1. An implantable medical device comprising:
- a housing which includes a power source and control electronics;
at least one lead extending from the housing and having one or more discrete reservoirs therein, each reservoir having at least one opening to an outer surface of the lead;
one or more sensors, which monitor or detects in vivo an analyte, biomarker, or physical parameter that is associated with cardiac health, located in the one or more reservoirs and in operable communication with said control electronics; and
at least one selectively disintegratable reservoir cap sealing each of said at least one opening of said one or more reservoirs,wherein the at least one reservoir cap is operably connected to the power source and control electronics to selectively disintegrate the reservoir cap and expose the one or more sensors in vivo.

Abstract
Implantable medical devices for cardiac care are provided that include a housing having a power source and control electronics; at least one lead extending from the housing and having one or more discrete reservoirs therein, each reservoir having an opening to an outer surface of the lead; one or more sensors, which monitor or detects an analyte, biomarker, or physical parameter that is associated with cardiac health, located in the reservoirs and in operable communication with said control electronics; and at least one selectively disintegratable reservoir cap sealing each of the reservoir openings, wherein the reservoir cap is operably connected to the power source and control electronics to disintegrate the reservoir cap and expose the sensors in vivo. The sensor may detect an analyte or biomarker selected from potassium ion, sodium ion, lithium ion, magnesium ion, ammonium ion, ionized calcium, lactate, oxygen, carbon dioxide, and creatinine, urea, BUN, and bilirubin.

17. A method of monitoring a patient in need of cardiac care comprising:
-
implanting into a patient a medical device which comprises a housing which includes a power source and control electronics, at least one lead extending from the housing and having one or more discrete reservoirs therein, each reservoir having at least one opening to an outer surface of the lead, one or more sensors, which monitor or detects in vivo an analyte, biomarker, or physical parameter that is associated with cardiac health, located in the one or more reservoirs and in operable communication with said control electronics, and at least one reservoir cap sealing each of said at least one opening of said one or more reservoirs, wherein the at least one reservoir cap is operably connected to the power source and control electronics; opening the at least one opening of the at least one reservoir in response to the control electronics and exposing the one or more sensors in vivo; and using the one or more sensors to monitor or detect an analyte, biomarker, or physical parameter associated with the health of the patient'"'"'s heart. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
