Implantable fluid dispenser
First Claim
1. An implantable drug delivery depot for transcutaneous access by a conduit directed substantially parallel to the skin which comprisesa rigid-walled drug reservoir,a flattened, penetrable drug reservoir inlet septum which defines a first plane,a substantially flat reservoir anchoring flange which defines a second plane, said first and second planes being substantially perpendicular, together witha tubular drug reservoir outlet adapted to avoid inadvertent penetration by the conduit, said outlet being bent or directed at an angle away from said flange to enter said reservoir remote from the conduit tip.

Abstract
An implantable drug delivery depot has penetrable inlet means which define a first plane and anchor means which define a second plane. According to the invention, the first and second planes are substantially perpendicular. When the depot is implanted with the anchor means parallel to the skin surface, the inlet means is oriented so that a hypodermic needle penetrating the inlet means is nearly parallel to the skin surface, reducing the danger of dislodgement of the needle from the inlet.
