Repositioning sheath for use in a percutaneous circulatory support system

A percutaneous circulatory support system, comprising:

• a blood pump;
• a housing;
• an elongate shaft extending from the blood pump to the housing;
• and
• a repositioning sheath comprising:
• a body portion including a lumen extending therethrough;
• a sheath extending distally from the body portion, the sheath including a lumen in communication with the lumen of the body portion, wherein the sheath is configured to fluidly engage with a vasculature of the patient;
• and
• a locking portion secured to the body portion, wherein the locking portion is configured to shift between an unlocked configuration and a locked configuration;
• wherein a sterile sleeve extends from the housing and surrounds at least a portion of the elongate shaft;
• wherein the sterile sleeve is configured to releasably couple to the locking portion of the repositioning sheath.

• wherein the locking portion includes:
• a polymeric tube including a lumen in communication with the lumen of the body portion, wherein the lumen of the polymeric tube is configured to receive an elongate shaft therein;
• and
• a locking mechanism configured to squeeze the polymeric tube against the elongate shaft when the elongate shaft is disposed within the lumen of the polymeric tube in the locked configuration;
• wherein the locking portion is self-biased toward the locked configuration.
