Method and System for Drug Delivery
First Claim
1. A system for drug delivery, comprising:
- a hysteroscope including a working channel; and
a medical device configured to position within the working channel of the hysteroscope, the medical device including;
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 lumen extending therethrough;
a second elongate member positioned within the lumen of the first elongate member and including a proximal end, a distal end and 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 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 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.

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.

9. A method of delivering a drug to a uterus, the method comprising:
-
transcervically positioning a delivery device within a uterine cavity until a distal end of the delivery device is near or contacting the fundus, where the delivery device includes a second elongate member included in a lumen of a first elongate member and a stopper device configured to define a retracted position and an extended position of the second elongate member relative to the first elongate member;
translating the second elongate member within the lumen of the first elongate member toward the distal end of the delivery device and from a retracted position to an extended position;
penetrating tissue at or near the fundus with a distal tip of the second elongate member, the second elongate member including a lumen filled with a drug; and
purging at least some of the drug from the lumen of the second elongate member into the tissue at approximately the fundus. - View Dependent Claims (10, 11, 12, 13, 14, 15)
