Compositions and methods for reducing lung volume
View Patent ↗The invention includes a method for performing non-surgical lung volume reduction in a patient by applying an amount of energy with a catheter to a diseased alveolar region of the lung of a patient having emphysema, wherein the amount of energy is sufficient to damage the epithelial cells and the epithelial barrier within the diseased alveolar region of the lung and collapse at least a portion of said region thereby reducing the lung volume, and wherein the energy comprises thermal energy, electrical energy, and ultrasonic energy.
1. A method for non-surgical lung volume reduction, the method comprising applying an amount of energy with a catheter to a diseased alveolar region of the lung of a patient having emphysema, wherein the amount of energy is sufficient to damage the epithelial cells and the epithelial barrier within the diseased alveolar region of the lung and collapse at least a portion of said region thereby reducing the lung volume.
2. The method of claim 1 , wherein the energy comprises thermal energy and is applied as heat.
3. The method of claim 2 , wherein the catheter transfers heat to the alveolar region.
4. The method of claim 1 , wherein the energy comprises ultrasonic energy.
5. The method of claim 4 , wherein the catheter transmits the ultrasonic energy to the alveolar region.
6. The method of claim 1 , wherein the energy comprises electrical energy.
7. The method of claim 6 , wherein the catheter transmits the electrical energy to the alveolar region.
