Abstract: The present disclosure provides catheter pump system including a catheter assembly configured to be at least partially inserted into a left ventricle (LV). The catheter assembly has a proximal end and a distal end, and includes an elongate body extending between the proximal end and the distal end. The catheter pump system further includes a pressure sensor disposed at the distal end and configured to measure a pressure within a left ventricle when the catheter assembly is inserted.

Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.

Abstract: A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. The catheter pump system can include a motor assembly, the motor assembly comprising a chamber and a shaft-driving portion disposed in the chamber. The shaft-driving portion can be configured to impart rotation to the impeller through the shaft assembly. The chamber can be filled with a gas that at least partially surrounds the shaft-driving portion. A fluid pathway can convey fluid proximally during operation of the catheter pump system. A bypass pathway can be in fluid communication with the fluid pathway, the bypass pathway configured to direct at least a portion of the fluid to bypass the chamber.
