Intra-bronchial obstructing device that controls biological interaction with the patient
First Claim
1. A method of treating a lung of a patient using an intra-bronchial device while controlling biological interaction of the device with the patient, the method including the steps of:
- providing an intra-bronchial device that comprises a one-way valve, the intra-bronchial device precludes air from being inhaled through an air passageway into a lung portion when inserted into the air passageway communicating with the portion of the lung;
associating a medicant that controls the biological interaction with the intra-bronchial device; and
inserting the intra-bronchial device in the air passageway.

Abstract
The present invention provides an intra-bronchial device and method that controls biological interaction of the device with the patient. The intra-bronchial device is adapted to be placed in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member that prevents air from being inhaled into the lung portion to collapse the lung portion, and a medicant carried by the obstructing member. The medicant may overlie at least a portion of the obstructing member, or the medicant may be absorbed in at least a portion of the obstructing member. The obstructing member may further include an absorptive member, and the medicant is absorbed by the absorptive member.

13. A method of treating a lung comprising:
-
providing an implantable obstruction device at a distal end of a delivery catheter, the obstruction device comprising a membrane on an outer portion thereof;
associating a medicant with the obstruction device;
guiding the distal end of the catheter to a delivery site in a lung and deploying the obstruction device in an air passageway of the lung so as to preclude air flow in at least one direction through the air passageway; and
removing the catheter from the lung and leaving the implanted obstruction device in place;
wherein the obstruction device comprises a one-way valve and further comprising placing the obstruction device in an air passageway in an orientation that prevents fluid from flowing distal of the device while allowing fluid to travel in a proximal direction past the device. - View Dependent Claims (14, 15, 17, 18, 19)

removing the catheter from the lung and leaving the implanted obstruction device in place; and
configuring and deploying the obstruction device so as to maintain a mucociliary pathway between a distal side and a proximal side of the obstruction device.
