Tuned strength chronic obstructive pulmonary disease treatment
First Claim
1. A method for treating a lung of a patient with chronic obstructive pulmonary disease, the method comprising:
- determining a regional tissue characteristic of at least a portion of lung tissue of the patient; and
selecting between a first coil having a first austenite final tuning and a second coil having a second austenite final tuning different than the first austenite final tuning based on the determined regional tissue characteristic of the portion of lung tissue, wherein the first austenite final tuning is characterized by a first transition temperature that is higher than a second transition temperature of the second austenite final tuning.

Abstract
The present invention generally provides improved medical devices, systems, and methods, particularly for treating one or both lungs of a patient with an implant, such as a coil, having a strength tuned to a patient'"'"'s tissue treatment region. More particularly, embodiments of the present invention include a method for treating a lung of a patient with chronic obstructive pulmonary disease. The method comprises determining a regional tissue density of at least a portion of lung tissue of the patient and selecting between first and second coils based on the determined regional tissue density of the portion of lung tissue. In particular, the first coil has a first austenite final tuning and second coil has a second austenite final tuning different than the first tuning. Determining may comprise imaging at least the portion of lung tissue of the patient so as to identify a localized lung tissue density. Selecting may comprise matching the determined tissue density of the treatment region to a tuned strength of the first or second coil.

24. A method for treating a lung of a patient with chronic obstructive pulmonary disease, the method comprising:
-
determining a regional tissue characteristic of at least a portion of lung tissue of the patient, wherein the determining comprises identifying a first tissue region of lung tissue having a first regional tissue density; selecting between a first coil having a first austenite final tuning and a second coil having a second austenite final tuning different than the first austenite final tuning based on the determined regional tissue characteristic of the portion of lung tissue, wherein the first coil has a first coil strength and the second coil has a second coil strength, the first coil strength less than the second coil strength, and wherein the selecting comprises selecting the first coil for deployment in the first tissue region in response to the first regional tissue density; identifying a second tissue region of the lung having a second regional tissue density different than the first regional tissue density, wherein the determined regional tissue characteristic indicates the first tissue region has a first tissue strength and the second tissue region has a second tissue strength, the first tissue strength less than the second tissue strength; and selecting the second coil for deployment in the second tissue region of the lung in response to the second regional tissue density, wherein the second coil strength is sufficiently mismatched to the first tissue strength that deployment of the second coil in the first tissue region would be undesirable.

-
determining a regional tissue characteristic of at least a portion of lung tissue of the patient; selecting between a first coil having a first austenite final tuning and a second coil having a second austenite final tuning different than the first austenite final tuning based on the determined regional tissue characteristic of the portion of lung tissue, wherein the first and second coils are included in a group of candidate coils having differing strengths at body temperature and differing lengths; and selecting a subset of the group of candidate coils for deployment in a first tissue region in response to a measurement of a length of the first tissue region, the subset of the group of candidate coils having similar lengths and including the first coil and the second coil. - View Dependent Claims (26, 27)
