Abstract
An introducer sheath (300) includes a body (305) extending between a leading end (304) and a trailing end (302) and including a plurality of rectangular segments (310) extending from the leading end to the trailing end. The segments are joined to one another along longitudinal edges to form a tubular structure with a lumen (308) therethrough, the segments being joined at vertices (314). The body has a collapsed condition with a first cross-section and is configured to transition from the collapsed condition to an expanded condition with a second cross-section when an apparatus is passed through the lumen, the second cross-section having a maximum dimension larger than a maximum dimension of the first cross-section.
