摘要:
Embodiments provide apparatus and methods for delivering solid form drug (SFD) to various locations in the body. In one embodiment, the invention provides an apparatus for treatment of arrhythmia comprising a drug delivery member (DDM) coupled to a drug storage device (DSD). The DSD is configured to store and advance SFD (e.g., drug pellets) through the DDM to a target tissue site (TTS) in or on the heart. A drug advancement member may be used to advance the SFD through the DSD. A capture chamber (CC) may be coupled to the DDM. and is configured to be positioned on a heart surface and allow SFD to dissolve to deliver a drug solution to the heart. The DSD can be implanted subcutaneously e.g., in the pectoral area. Embodiments of the apparatus can be used to store and deliver SFD to the heart or other TTS over an extended period of years.
