IMPLANTABLE DRUG PUMPS AND REFILL DEVICES THEREFOR

摘要

Implanted drug pump devices can be refilled via a fill port (124) in the drug reservoir (104) that includes a self-resealable septum (240). Proper needle insertion may be verified visually or using electrical, magnetic, optical, acoustic, or other suitable sensing mechanisms. Wireless data exchange between a refill system and the implanted device may be facilitated, e.g., to verify proper drug selection prior to commencement of the refill process.
