Abstract
A surgical instrument and method for facilitating the resection of an anatomic structure in a minimally invasive procedure. The resection instrument includes an inflatable enveloping sleeve member that has an inflation chamber lying between an outer sleeve and an inner sleeve thus providing an inflatable chamber that surrounds an 'organ lumen' extending along the member's longitudinal axis. The enveloping member typically is of non-elastomeric sheet material and in the collapsed state is folded and stored in the instrument's handle by turning both the inner and lumen sleeves 'inside-out'. The instrument is disposed proximate to the anatomic structure to be resected and the enveloping member is inflated. As the inflation chamber is inflated, the enveloping member deploys distally turning itself 'right-side-out' and is capable of circumferentially enveloping the anatomic structure (or portion thereof) thus progressively capturing the structure within the organ lumen. Thus, the enveloping member bluntly dissects connective tissues in 360.degree. surrounding the structure creating an anatomic space. Thereafter, the anatomic structure may be divided beyond the distal end of the enveloping member and the instrument and resected structure withdrawn.
