Drive mechanism for powering intravascular blood pumps

摘要: A disposable, sterilizable cable drive unit for an intravascular blood pump includes a rotor enclosed in fluid-tight enclosure which can be slipped into the stator of motor. The is connectable to constant-rate purge fluid supply and dual-lumen sheath. One lumen provides sterile path; other carries return path flushing immersed. derived from at constant rate, may also immersed it if desired. held motor by manually operated detent, self-centering action aligns with when energized. mounted on gimbel so as alignable sheath its point insertion patient's vascular system, order prevent stresses patient kinks
