Title:
RETRACTABLE SHEATH
Document Type and Number:
WIPO Patent Application WO/2020/051802
Kind Code:
A1
Abstract:
In some examples, a sheath may define a lumen and include a proximal sheath portion and a distal sheath portion. The distal sheath portion defines a first proximal end and a second proximal end proximal to the first proximal end, and is configured to rotate relative to the proximal sheath portion between a first rotational orientation and a second rotational orientation. When the distal sheath portion is in the first rotational orientation, the first proximal end is separated from the proximal sheath portion by a first distance, and when the distal sheath portion is in the second rotational orientation, the first proximal end is separated from the proximal sheath portion by a second distance. The second distance is less than the first distance such that the distal sheath portion can be retracted relative to the proximal sheath portion.
