DEVICES AND METHODS TO MAINTAIN THE PATENCY OF AN OPENING RELATIVE TO PARENCHYMAL TISSUE OF THE LUNG
First Claim
Patent Images
1. A system to maintain luminal patency proximate to an opening in parenchymal tissue of the lung comprising:
- an implant with a lumen and an opening communicating with the lumen, said opening of said implant is adapted to be implanted one of adjacent to and in the parenchymal tissue;
a device that is used in combination with the implant, wherein said device is associated with the opening of said implant and which device includes a surgical instrument with a sharp tip; and
wherein said device can interfere with at least one of tissue buildup and secretional buildup.

Abstract
A mechanical device and/or chemical process is utilized to maintain luminal patency in conduits or other devices implanted in the lung or lungs of a patient. The mechanical device and/or chemical process ensures that air flows freely through a conduit implanted through an anastomosis into a lung. The device is suitable for use in conjunction with ventilation bypass treatments for chronic obstructive pulmonary disease.

12. A method to maintain luminal patency proximate to an opening in a parenchymal tissue comprising the steps of:
-
placing an implant through the chest wall so that the opening is located one of adjacent and in parenchymal tissue of the lung, wherein said implant includes a lumen and an opening communicating with the lumen; and using a device in combination with the implant, which device has a sharp tip, to interfere with at least one of tissue buildup and secretional buildup in order to maintain patency. - View Dependent Claims (13, 14, 15, 16)

17. A system to maintain luminal patency proximate to an opening in parenchymal tissue of the lung comprising:
-
an implant with a lumen and an opening communicating with the lumen, said opening of said implant is adapted to be implanted one of adjacent to and in the parenchymal tissue; a device to be used in combination with and received inside of the lumen of the implant, wherein said device is associated with the opening of the implant; wherein said device is a surgical instrument with a sharp tip; and wherein said device can move relative to the implant in order to interfere with at least one of tissue buildup and secretional buildup.
