1. A method of implanting a medical device in a body lumen comprising:
- advancing a delivery catheter having the medical device disposed within an interior of the delivery catheter, through the body lumen to a deployment site, the medical device being selected from the group consisting of stents and valves, the delivery catheter defining at least one adhesive delivery channel having at least one discharge opening that either faces distally and extends through a distal end face of the delivery catheter to discharge adhesive in a distal direction distally beyond the distal end face, or that extends through a sidewall of the delivery channel and faces radially outward from the delivery channel relative to a longitudinal axis of the delivery catheter to discharge adhesive in a radially outward direction, for discharging the adhesive therefrom; and
thereafter, deploying the medical device from the delivery catheter at the deployment site while discharging an adhesive from the adhesive delivery channel in the delivery catheter during deployment of the medical device, the adhesive being discharged onto the medical device, a wall of the body lumen, or combinations thereof.

16. A delivery catheter for a medical device comprising:
-
an inner shaft; an inner sheath having a longitudinal axis and extending around the inner shaft, the inner sheath comprising a distal end region and defining at least one adhesive delivery channel comprising a discharge opening, the adhesive delivery channel forming the distal end region of the inner sheath; and an outer sheath; wherein the distal end region of the inner sheath is configured to move between a first configuration in which the at least one adhesive delivery channel extends along the longitudinal axis when the inner sheath is disposed within the outer sheath, to a second configuration in which the at least one adhesive delivery channel is moved radially outward relative to the inner shaft upon an initial retraction of the outer sheath.

17. A method of implanting a medical device in a body lumen comprising:
-
advancing a delivery catheter having the medical device disposed within an interior of the delivery catheter, through the body lumen to a deployment site, the delivery catheter comprising a distal tip, the delivery catheter defining an adhesive delivery channel having a discharge opening positioned in the distal tip; thereafter, discharging an adhesive from the distal tip of the delivery catheter onto an inner surface of the body lumen at the deployment site; and deploying the medical device from the delivery catheter in the body lumen at the deployment site immediately after discharging the adhesive. - View Dependent Claims (18, 19, 20)
