MECHANICAL CIRCULATORY SUPPORT SYSTEM WITH REPOSITIONING SHEATH

Abstract

A medical device system may include a medical device, an elongate shaft, a first sheath, and a second sheath. The elongate shaft may couple with the medical device and extend proximally from the medical device. The first sheath may have an elongate tube configured to expand from a first inner diameter to a second inner diameter. The first sheath and the second sheath may longitudinally advance over the elongate shaft and a distal end of the second sheath may advance through the lumen and extend distally beyond a distal end of the first elongate tube into a vascular access site. The system may include a closure device configured to close the vascular access site around the second sheath. The medical device may be or include a blood pump configured to pump blood from a ventricle of a heart of a patient to vasculature of the patient.
