Benefits of technology
The solution simplifies resection procedures by eliminating the need for suturing, reducing complications, and enabling lung volume reduction with improved pulmonary function without invasive suturing, applicable beyond lung tissue for various body tissues.
Problems solved by technology
Chronic Obstructive Pulmonary Disease (COPD) has become a major cause of morbidity and mortality in the United States over the last three decades.
The airflow obstruction in COPD is due largely to structural abnormalities in the smaller airways.
Although the surgery was deemed promising, the procedure was abandoned.
However, the procedure has fallen out of favor due to the fact that Medicare stopped remitting for LVRS.
Unfortunately, data is relatively scarce and many factors conspire to make what data exists difficult to interpret.
However, the surgery is very invasive and fraught with complications.
Among the complications is the potential for lung air leaks.
Lung tissue is very thin, and fragile hence difficult to suture together.
In about thirty percent (30w) of the cases, the difficulty with suturing lung tissue results in air leaks.
With increasing age, a patient may develop a weakened section of lung which may then rupture due to an extreme pressure differential, such as may result from simply a hard sneeze.
Patients with AIDS and pulmonary complications can suffer from air leaks.

Embodiment Construction
[0054]Referring now to FIG. 1, it is a sectional view of a healthy respiratory system. The respiratory system 20 resides within the thorax 22 which occupies a space defined by the chest wall 24 and the diaphragm 26.
[0055]The respiratory system 20 includes the trachea 28, the left mainstem bronchus 30, the right mainstem bronchus 32, and the bronchial branches 34, 36, 38, 40, and 42. The respiratory system 20 further includes left lung lobes 52 and 54 and right lung lobes 56, 58, and 60. Each bronchial branch communicates with a respective different portion of a lung lobe, either the entire lung lobe or a portion thereof.
[0056]A healthy respiratory system has an arched or inwardly arcuate diaphragm 26. As the individual inhales, the diaphragm 26 straightens as illustrated in FIG. 1 to increase the volume of the thorax 22. This causes a negative pressure within the thorax. The negative pressure within the thorax in turn causes the lung lobes to fill with air to an inflated condition a...

A resection device and method permits safe and efficient encapsulation, isolation and resection of body tissue. The device includes a sheath of flexible and severable material configured to receive the body tissue to be resectioned as it is drawn therein. The sheath may be expandable and held in an expanded condition as the body tissue to be resectioned is drawn into the sheath. Thereafter, the sheath is permitted to collapse about the body tissue to contain and constrict the body tissue. Once the body tissue to be resectioned is disposed in the sheath, the sheath is severed to resection the body tissue.

RELATED APPLICATIONS[0001]This is a continuation of U.S. application Ser. No. 10 / 287,188, filed on Nov. 4, 2002, now U.S. Pat. No. 6,790,172 which is a continuation of U.S. application Ser. No. 09 / 780,232, filed on Feb. 9, 2001, now U.S. Pat. No. 6,485,407, which is a continuation-in-part of U.S. application Ser. No. 09 / 534,244 filed Mar. 23, 2000, now U.S. Pat. No. 6,328,689, the entirety of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention is generally directed to an apparatus and method for resectioning body tissue. The present invention is more particularly directed to such an apparatus and method which may be used on various types of body tissue and which greatly simplifies resection procedures.[0003]Chronic Obstructive Pulmonary Disease (COPD) has become a major cause of morbidity and mortality in the United States over the last three decades. COPD is characterized by the presence of airflow obstruction due to chronic bronchitis o...
