Sheath with Mechanism to Stop Bleeding Around Access Site

A blood pump delivery system comprising:

• a repositioning sheath for insertion into an access site of a blood vessel and for use in positioning a blood pump within the blood vessel, the repositioning sheath comprising:
• a distal end opposite a proximal end,
• a sheath body extending between the distal end and the proximal end, the sheath body defining a sheath lumen for receiving the blood pump, and
• a plug arranged around the sheath body and proximally to the distal end of the repositioning sheath, the plug defined by a first disc having a cylindrical shape and a second disc having a cylindrical shape, the first disc and the second disc coupled by a connector portion extending between the first disc and the second disc,
• wherein the first disc is configured to be positioned within the blood vessel and against a wall of the blood vessel,
• wherein the second disc is configured to be positioned outside of the blood vessel such that the plug seals the access site.

A method comprising:

• inserting a sheath into a blood vessel, the sheath having a diameter that is less than a diameter of an access sheath used to initially access the blood vessel at an access site;
• inserting a plug onto a proximal end of the sheath and arranging the plug around the sheath, the plug including at least a first disc and a second disc;
• inserting the plug into the blood vessel while the plug is in a collapsed configuration such that the first disc is inserted through the access site and into the blood vessel;
• and
• expanding the plug such that the first disc is in contact with the blood vessel and seals the access site.
