RETRACTABLY EXPANDABLE INTRODUCER SHEATH AND ASSOCIATED METHODS

Abstract

An introducer sheath and associated methods are disclosed herein. An example introducer sheath may include an elongate shaft having a proximal end, a distal end and a lumen extending therebetween. The elongate shaft may further include a retractably expandable section disposed between the proximal end and the distal end, the retractably expandable section may include one or more layers. At least a portion of the retractably expandable section may include a cut pattern formed in the one or more layers. The retractably expandable section may accept passage of a device through the lumen along the retractably expandable section and transition from a radially collapsed configuration before passage of the device through the retractably expandable section, to a radially expanded configuration during passage of the device through the retractably expandable section, and to a radially retracted configuration after passage of the device therethrough.
