Medical Devices for Delivery and Retention of Bioactive Agents

摘要

Medical devices for local bioactive delivery are described. A medical device has an elongate shaft extending between proximal and distal ends and a distal portion that defines a pigtail. A balloon is disposed on the elongate shaft proximal to the pigtail. The elongate shaft defines a first working lumen with a distal opening disposed between the balloon and the pigtail, and a second working lumen with a distal opening disposed distal to the first working lumen distal opening. Methods of using medical devices are also described.

1. A medical device for delivering a bioactive to a point of treatment and retaining the bioactive at the point of treatment for a desired period of time, said medical device comprising:
an elongate shaft extending between proximal and distal ends and having a distal portion extending proximally from the distal end and defining a pigtail; a balloon disposed on the elongate shaft proximal to the pigtail, the balloon defining an interior chamber; the elongate shaft defining an inflation lumen extending between an inflation lumen proximal opening and an inflation lumen distal opening disposed within the interior chamber of the balloon; the elongate shaft defining a first working lumen extending between a first working lumen proximal opening and a first working lumen distal opening disposed between the balloon and the distal end; and the elongate shaft defining a second working lumen extending between a second working lumen proximal opening and a second working lumen distal opening disposed distal to the first working lumen distal opening and distal to the balloon.
