Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
111 words
A method of selectively compressing a lung of a patient comprising: selecting one of a right lung or a left lung; advancing a device through a trachea of the patient into the selected lung; venting a first portion of the selected lung to the exterior of the patient through the device the first portion being targeted for compression; isolating the first portion of the selected lung from a second portion of the selected lung adjacent the first portion; and delivering sufficient pressurized fluid through one or more ports of the device to air passageways of the second portion of the selected lung to compress the first portion of the selected lung.
Claim 2
Independent Claim
111 words
A method of selectively compressing a lung of a patient comprising: selecting one of a right lung or a left lung; advancing a device through a trachea of the patient into the selected lung; venting a first portion of the selected lung to the exterior of the patient through the device the first portion being targeted for compression; isolating the first portion of the selected lung from a second portion of the selected lung adjacent the first portion; and delivering sufficient pressurized fluid through one or more ports of the device to air passageways of the second portion of the selected lung to compress the first portion of the selected lung.
