Abstract

A guidewire for backloading and inserting a percutaneous pump affixed to a cannula includes a proximal section made of a first material, with a first diameter, a rounded proximal end, and a distal end. The guidewire also includes a distal section made of a second material, with a second diameter which is greater than the first diameter, a distal end, and a proximal end abutting the distal end of the proximal section. The first material of the proximal section is selected to be softer than a material of the percutaneous pump to reduce damage to the pump during backloading. The distal section of the guidewire is configured to be stiffer than the proximal section to insert the percutaneous pump in a desired location without damaging the guidewire.
