Method and system for drug delivery
First Claim
1. A drug delivery device adapted for insertion into a working channel of a hysteroscope comprising:
- a first elongate member configured for transcervical insertion into a uterine cavity, the first elongate member including a proximal end, a distal end and a first lumen, a second lumen and a third lumen extending therethrough between the proximal and distal ends, wherein the second lumen includes light fibers and the third lumen includes a micro-endoscope;
a light post coupler coupled to the light fibers and configured to couple to a light source;
a camera adapter coupled to the micro-endoscope and configured to couple to a camera;
a second elongate member positioned within the first lumen of the first elongate member and including a proximal end, a distal end and a lumen therethrough, where;
the second elongate member is positionable in a retracted or an extended position relative to the first elongate member;
the distal end of the second elongate member is configured to extend beyond the distal end of the first elongate member and pierce uterine tissue when in the extended position;
the proximal end of the second elongate member is configured to receive a drug for delivery through the lumen of the second elongate member; and
a stopper device configured to control movement of the second elongate member within the first elongate member thereby defining the retracted and extended positions of the second elongate member, the stopper device including a first gripping member fixedly secured to the proximal end of the first elongate member and a second gripping member fixedly secured to the proximal end of the second elongate member, where the second gripping member is configured to abut the first gripping member in a non-engaging fashion when the second elongate member is in the extended position.

Abstract
A medical device and procedure for delivering a drug into a uterus are described. In one implementation, the medical device includes a first elongate member, a second elongate member and a stopper device. The first elongate member is configured for transcervical insertion into the uterus and includes a lumen extending therethrough. The second elongate member is positioned within said lumen and also includes a lumen therethrough. The second elongate member is positionable in a retracted or an extended position. A distal end of the second elongate member is configured to extend beyond a distal end of the first elongate member and penetrate uterine tissue when in the extended position. A proximal end of the second elongate member is configured to receive a drug for delivery through the lumen of the second elongate member. The stopper device controls movement of the second elongate member within the first elongate member.
