Abstract
The two-piece percutaneous introducer sheath includes a distal portion which can remain in a blood vessel while a proximal portion can be removed after a valve at the proximal end of the distal portion is closed thus preventing undue loss of blood. Thus, a thrombus that has been pulled into the proximal portion can be removed when the proximal portion is removed without any significant blood loss after the sheath valve has been closed. Further, for any other useful therapeutic purpose, the proximal portion can be changed while the distal portion with its valve closed can remain in place in the vessel.
