Publication number: 20030149446Abstract: The invention provides for treating deleterious body tissue located within healthy body tissue by isolating the deleterious tissue from blood, air, and fluid communication. The device includes two structures, each having a corresponding circumferential surface arranged to circumscribe the deleterious body tissue. When the first and second circumferential surfaces are brought together in an aligned relationship with the deleterious body tissue between the structures, the two circumferential surfaces co-act to isolate the deleterious body tissue 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.Type: ApplicationFiled: February 1, 2002Publication date: August 7, 2003Applicant: Spiration, Inc.Inventor: Brandon James Shuman

Publication number: 20020188171Abstract: An apparatus and method reduces the size of a lung. The apparatus includes a jacket of flexible fabric configured to cover at least a portion of the lung. A lace, carried by the jacket, collapses the jacket about the lung portion. The jacket may further include a drawstring circumscribing the jacket at the base for closing the open base of the jacket about the lung portion. The collapsing of the jacket may be employed for both reducing the size of the lung and maintaining the lung in a reduced size condition or the lung portion may be deflated prior to the placement of the jacket over the lung portion, in which case, the jacket serves to prevent re-expansion of the lung portion.Type: ApplicationFiled: July 18, 2002Publication date: December 12, 2002Applicant: Spiration, Inc.Inventors: Clifton A.
