<p>Embodiments provide apparatus and methods for delivering solid form medications such as pellets to various locations in the body. One embodiment provides an apparatus for in vivo delivery of medication pellets comprising a housing including a port a pellet containing belt disposed in the housing and a mechanism for transferring the pellets from the belt to a delivery site (DS) outside the housing. Each pellet contains a dose of drug to treat a medical condition. An elongate member is coupled to the housing and includes a lumen for pellet delivery a proximal end coupled to the port and a distal end positioned at the DS. The pellet can be delivered to the DS at regular intervals or responsive to a detected biological event. Embodiments of the invention are particularly useful for delivering medication to treat a medical condition over an extended period without requiring a patient to take external medication.</p> |
