Abstract
Disclosed are methods, devices, and systems for treating a body lumen with a sclerothepeutic agent. The method includes the steps of positioning a porous balloon assembly at a site in the lumen to be treated, inflating the assembly to establish a close approximation to the lumen wall, forcing the sclerotherapeutic agent to exit the pores and come in contact with the lumen wall, and to deflate and retrieve the balloon assembly. The methods, devices and systems disclosed herein are especially useful for the treatment of incompetent veins and their contributory branches.
Claims19
A method for tumescent anesthesia-free treatment of a body lumen having a lumen wall, the method comprising:
- positioning an inflatable balloon assembly at a location in the body lumen to be treated, the inflatable balloon assembly having a porous balloon chamber and one or more pores in an outer wall;
- inflating the porous balloon assembly into an inflated configuration in a manner that the outer wall of the inflatable balloon assembly abuts the lumen wall;
- forcing a sclerotherapeutic agent to exit the one or more pores of the inflatable balloon assembly and to contact the lumen wall;
- and
- retaining the sclerotherapeutic agent between the lumen wall and the outer wall of the inflatable balloon assembly when the inflatable balloon assembly is in the inflated configuration.
A method for tumescent anesthesia-free treatment of a body lumen having a lumen wall, the method comprising:
- positioning an inflatable balloon assembly at a location in the body lumen to be treated, the inflatable balloon assembly having multiple porous balloon chambers folded around a guidewire;
- unfolding and expanding the multiple porous balloon chambers of the inflatable balloon assembly into an unfolded configuration in a manner that outer walls of the multiple porous balloon chambers abut the lumen wall;
- forcing a sclerotherapeutic agent through one or more pores of the multiple porous balloon chambers to contact the lumen wall;
- and
- retaining the sclerotherapeutic agent between the lumen wall and the outer walls of the multiple porous balloon chambers when the multiple porous balloon chambers are in the unfolded configuration.
A device for administering a beneficial agent into a body lumen, the device comprising:
- a balloon assembly having a compliant balloon chamber with a chamber wall;
- and
- at least one pore in the chamber wall, the at least one pore being located at a reinforcement in the chamber wall.
