摘要：
Percutaneous access sheaths used to provide access to the vasculature and heart for the introduction of percutaneous ventricular assist devices (pVADs), and to remain in place for the duration of pVAD use. The sheaths include actively closeable seals engageable to seal against the drive lines of the pVADs to minimize blood loss during pVAD use.
