Abstract
A sheath is configured for elongation from a first length to a second, longer length and a retention member retains the sheath at the first length. A portion of the retention member is removed or disengaged, the sheath is released and expands in situ to the second longer length. A method for releasing the retention member is also disclosed.
Claims15
A method of treating a patient, comprising the steps of:
- positioning a sheath within a body lumen, the sheath defining a longitudinal axis, and being adapted to transition in situ from a first condition having a first longitudinal length to a second condition having a second, greater longitudinal length;
- advancing the sheath, in the first condition thereof, within the body lumen to a location adjacent an anastomotic site;
- and
- transitioning the sheath from the first condition to the second condition whereby the sheath extends across the anastomotic site to thereby assist in healing thereof.

A method of treating a patient, comprising the steps of:
- providing a sheath defining a longitudinal axis and having a distal portion and a proximal portion, the sheath having a first longitudinal length and a second longitudinal length greater than the first longitudinal length;
- providing a retention member extending between and connecting the distal portion and the proximal portion of the sheath to retain the sheath at the first longitudinal length, the retention member being severable to permit the sheath to elongate distally to assume the second longitudinal length traversing the anastomotic site;
- attaching the sheath in the first longitudinal length adjacent an anastomotic site in a body lumen;
- and
- severing the retention member to permit the sheath to assume the second, longer longitudinal length to extend across the anastomotic site.
