| 摘要 |
<p>The invention provides for treating deleterious body tissue located within healthy body tissue by isolating the deleterious tissue (70) from blood, air, and fluid communication. The device includes two structures (82, 86), each having a corresponding circumferential surface (83, 87) arranged to circumscribe the deleterious body tissue. When the first and second circumferential surfaces (83, 87) are brought together in an aligned relationship with the deleterious body tissue between the structures (82, 86), the two circumferential surfaces (83, 87) co-act to isolate the deleterious body tissue (70) from communication with the healthy body tissue. The deleterious tissue is resected according to the invention by allowing it to become ischemic and necrotic, or by excision.</p> |
