摘要：
Disclosed herein are heart pumps that include a catheter assembly and that can be applied percutaneously. Some embodiments include a locking device that prevents components of the catheter assembly from being separated when in use. The catheter assembly can include an expandable tip. In some embodiments, the catheter assembly includes a housing having a wall structure, a portion of which can have a bulbuous shape or can be deformable. In other embodiments, the housing can be configured to reduce fluttering or deflection of the housing and/or to maintain a gap between the housing and an impeller blade disposed therein.
