Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
91 words
An implantable drug delivery depot for transcutaneous access by a conduit directed substantially parallel to the skin which comprises a 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 with a 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.
Claim 2
Dependent Claim
91 words

Claim 3
Dependent Claim
18 words
The depot of claim 1 wherein said inlet presents an oval or eliptical aspect in said first plane.
Claim 4
Dependent Claim
15 words
