First Claim
Patent Images
1. An apparatus for positioning at a target site and for treating a pulmonary condition in a subject, said apparatus comprising:
- a fluid exchange catheter for insertion into a tracheo-bronchial tree, wherein in an operative configuration, fluid passes through and exits the fluid exchange catheter to reach lung tissue;
an inflatable balloon coupled to said fluid exchange catheter, at least a portion of said inflatable balloon configured to engage a luminal wall of the tracheo-bronchial tree adjacent an anterior pulmonary plexus or a posterior pulmonary plexus in an expanded configuration;
an energy delivering mechanism operably coupled to said inflatable balloon, said energy delivery mechanism including at least one energy delivery member configured to deliver electrical energy to at least one of the anterior pulmonary plexus or a posterior pulmonary plexus; and
an energy delivery source configured to deliver electrical energy to said at least one energy delivery member at a voltage of 0.1 to 50V, a current of 0.1 to 30 mA, a frequency of 5 to 300 Hz, and a pulse-width of 50 to 750 microseconds;
wherein delivery of said electrical energy to at least one of the anterior pulmonary plexus or a posterior pulmonary plexus treats the pulmonary condition.

Abstract
An apparatus for positioning at a target site and for treating a pulmonary condition in a subject includes a fluid exchange catheter for insertion into a tracheo-bronchial tree and an inflatable balloon coupled to the fluid exchange catheter. At least a portion of the inflatable balloon is for engaging a luminal wall of the tracheo-bronchial tree at the target site. The apparatus further includes an energy delivery mechanism operably coupled to the inflatable balloon. The energy delivery mechanism includes at least one energy delivery member for delivering electrical energy to the target site.
