Abstract
A method of delivering an agent into a bodily lumen, the method comprising: implanting an implantable medical device into a treatment site of a lumen, the device having an abluminal face and a luminal face, wherein the device includes depots that extend from an open end at a luminal face to an open end at an abluminal face; and introducing an agent into the open end of the depots at the luminal face such that the agent is delivered to the treatment site through the open end at the abluminal face.
Claims24
A method of delivering an agent into a bodily lumen, the method comprising:
- implanting an implantable medical device into a treatment site of a lumen, the device having an abluminal face and a luminal face, wherein the device includes depots that extend from an open end at a luminal face to an open end at an abluminal face;
- and
- during or after the implanting introducing an agent into the open end of the depots at the luminal face such that the agent is delivered to the treatment site through the open end at the abluminal face,
- wherein the introducing of the agent into the depots includes deploying an agent delivery catheter into the lumen, positioning the agent delivery catheter adjacent to the medical device, and delivering the agent by the agent delivery catheter into the depots.
A method of delivering an agent into a lumen, the method comprising:
- implanting a stent into a treatment site of a lumen, the stent having an abluminal face and a luminal face, wherein the stent includes depots that extend from an open end at the luminal face to an open end at the abluminal face, and wherein the open end at the luminal face is narrower than the open end at the abluminal face;
- deploying a catheter having a balloon into the lumen, the deploying including inflating the balloon, wherein upon inflation of the balloon, an agent is released from the balloon and is introduced by the inflation into the open end of the depots at the luminal face;
- and
- removing the catheter from the lumen.
A stent comprising:
- a body structure having a generally cylindrical shape, the body structure having an abluminal face and a luminal face;
- a plurality of depots, each depot extending from an open end at the luminal face to an open end at the abluminal face;
- and
- a cover at the open end at the luminal face of each depot, the cover having an open position for allowing an agent to be introduced into the depots and a closed position, the covers configured to move within their respective depots.
