Catheter pump with positioning brace
First Claim
1. A catheter pump assembly, comprising:
- an elongate body assembly having a proximal end, a distal end and at least one lumen extending therebetween;
a shaft disposed at least partially within the elongate body and journaled for rotation;
an impeller coupled with a distal portion of the shaft, the impeller configured to be rotated to induce flow of blood when the impeller is placed in fluid communication with a source of blood; and
an anchor disposed along an outer surface of the catheter pump assembly at an intermediate location and configured to be deployed therefrom to engage a vascular segment to hold in place a portion of the catheter pump assembly disposed in the patient.

Abstract
A catheter pump assembly is provided that includes an elongate body assembly, a shaft, and an impeller. The assembly has a proximal end, a distal end and at least one lumen extending therebetween. The shaft is disposed at least partially within the elongate body, e.g., in the at least one lumen, and journaled for rotation. The impeller is coupled with a distal portion of the shaft. The impeller is configured to be rotated to induce flow of blood when the impeller is placed in fluid communication with a source of blood. An inflatable balloon brace is disposed on an outer surface of the catheter pump. The inflatable balloon brace is spaced proximally of the impeller and has a low profile configuration for delivery through the vasculature and an expanded configuration for disposing (e.g., position and/or orienting) the impeller within the source of blood.

14. A method of positioning a catheter pump, comprising:
-
inserting a catheter pump into a peripheral vascular location, the catheter pump having an elongate body, a flow generating device disposed at a distal portion of the elongate body, and an anchor disposed proximally of the flow generating device; advancing the distal portion of the elongate body to a source of blood; expanding the brace from a side surface of the elongate body into contact with a target location within the patient; and operating the flow generating device within the source of blood to induce a blood flow. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
