Implantable medical device for delivering a liquid
First Claim
1. An implantable device (1) for administering medicines in liquid form, comprising:
- a reservoir (2);
a variable-volume chamber (5) having a volume determined by a position of at least a first movable volume limiter;
a first conduit (8) connecting the reservoir (2) to the variable-volume chamber (5) in order to fill the latter, said first conduit (8) comprising a valve;
a second conduit (8) coupled to the variable-volume chamber (5), the second conduit having an outlet end adapted to be disposed at a treatment site; and
a control box coupled to the valve and the at least first volume limiter, the control box programmed to control actuation of the valve and positioning of the first movable volume limiter.

Abstract
The invention concerns an implantable device (1) for delivering medicines in liquid form comprising: a reservoir (2) provided with an inlet (3) and an outlet (10), said reservoir (2) being adapted to expel the liquid; a variable volume chamber (5) provided with an inlet (11) and an outlet (12), the volume of the variable volume chamber (5) being in particular smaller than that of the reservoir (2); a first conduit (6) communicating the outlet (10) of the reservoir (2) with the inlet (11) of the variable volume chamber (5) to fill the latter; a second conduit (8) whereof one of the ends is connected on the outlet (12) of the variable volume chamber (5).
