摘要： A heart pump and a catheter assembly therefor are provided that include a flexible catheter body having a proximal end and a distal end, the catheter body having a plurality of lumens therethrough. The catheter body can be sufficiently flexible to extend from a peripheral access to a patient's heart. The catheter assembly can also include an impeller assembly having an impeller and a housing. The impeller assembly can be coupled with the flexible catheter body such that a tensile force applied to opposite ends of the catheter assembly enhances the security of the connection between the catheter body and the impeller assembly.

摘要： A blood pump includes an impeller having a plurality of foldable blades and a cannula having a proximal portion with a fixed diameter, and a distal portion with an expandable diameter. The impeller can reside in the expandable portion of the cannula. The cannula has a collapsed condition for percutaneous delivery to a desired location within the body, and an expanded condition in which the impeller can rotate to pump blood. A flexible drive shaft can extend through the cannula for rotationally driving the impeller within the patient's body.

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 bulbous 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.
