IMPLANTABLE DEVICE FOR CONTROLLED, EXTENDED DELIVERY OF PARATHYROID HORMONE
First Claim
1. An implantable device for the extended, controlled delivery of parathyroid hormone to a patient in need thereof comprising:
- a substrate having a plurality of discrete reservoirs therein;
a release system contained in each of the reservoirs, wherein the release system comprises parathyroid hormone in a dried or lyophilized form; and
a control means for selectively releasing a pharmaceutically effective amount of the parathyroid hormone from the reservoirs in daily intermittent doses of between about 10 and 300 μ

Abstract
Method and devices are provided for extended and controlled delivery of parathyroid hormone to a patient. The method includes implanting a medical device into the patient, the medical device comprising a substrate, a plurality of reservoirs in the substrate, a release system contained in each of the reservoirs, wherein the release system comprises parathyroid hormone; and controllably releasing a pharmaceutically effective amount of the parathyroid hormone from the reservoirs. The parathyroid hormone can be released intermittently, such as once daily over an extended period (e.g., two months, ten months, or more.). The device can further include reservoirs containing a bone resorption inhibitor or other drug for release. The devices are useful in delivering PTH for the treatment and prevention of bone loss, such as associated with osteoporosis.

9. An implantable device for controlled delivery of parathyroid hormone to a patient in need thereof comprising:
-
a substrate having a plurality of discrete reservoirs; a quantity of parathyroid hormone contained in each of the reservoirs; a plurality of reservoir caps separating said quantity of parathyroid hormone from an environment outside of the reservoirs, and preventing the parathyroid hormone from being released from the implantable device; and means for disintegrating one or more of the discrete reservoir caps to release the parathyroid hormone from one or more of the reservoirs, wherein each of said reservoir caps comprise a multi-layer metal structure. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
