Medical device with drug delivery member
First Claim
1. A medical device for delivering a therapeutic agent to an internal portion of a patient'"'"'s body, the medical device comprising:
- a shaft;
a self-expanding delivery member in operative communication with the shaft, the delivery member having a proximal end and a distal end and being shaped in a generally solid cylindrical configuration from a porous material capable of (i) releasing the therapeutic agent to the internal portion of the patient'"'"'s body and (ii) being in a collapsed state;
a therapeutic agent delivery lumen defined by a lumen wall, wherein the therapeutic agent delivery lumen is in fluid communication with the delivery member for fluidly connecting the delivery member with a therapeutic agent source; and
a retention member in operative communication with the delivery member, the retention member being configured and arranged to selectively collapse the delivery member;
wherein;
the lumen wall has one or more delivery openings therein for passage of the therapeutic agent therethrough; and
the delivery member is disposed around and in contact with at least a portion of the lumen wall and in contact with at least one of the delivery openings.
