Durable percutaneous left ventricular assist device

A system for delivery and placement of an intracardiac device within a patient, comprising:

• a deployment wire configured for percutaneous delivery of an intracardiac device to a cardiac chamber through a peripheral artery, the deployment wire having a proximal end portion and a distal end portion, the proximal end portion having a formed tip and the distal end portion configured to operatively connect to the intracardiac device;
• a sheath configured for percutaneous insertion into a cardiac chamber wall through a chest wall, wherein the sheath includes:
• a tubular body extending along an axis and having a proximal end portion, distal end portion, and a flexible portion therebetween configured for axial movement to accommodate cardiac movement during placement and delivery of the intracardiac device in the cardiac chamber,
• wherein the sheath is configured to be inserted through the chest wall and into the cardiac chamber wall such that the flexible portion is within the chest wall or pericardium and proximate the chamber wall;
• and
• wherein the distal end portion includes one or more anchoring features configured to actuate between a deployed position where the one or more anchoring features extend radially outward from the distal end portion of the sheath, and a retracted position where the one or more anchoring features are within the distal end portion;
• and
• a snare configured to be passed through the sheath into the cardiac chamber for snaring the formed tip of the deployment wire to pull the deployment wire and intracardiac device through the peripheral artery and into the cardiac chamber.
