Support for assist device

A support system aimed at securing an assist device inside a patient's heart, the assist device comprising a pump and a pump body with an entrance and an exit cylinder, the pump being situated inside the pump body and being in fluidic communication with the entrance and the exit cylinder, the support system comprising:

• an upstream support element, aimed at securing the upstream extremity of the pump body to the patient's heart, the upstream support element comprising at least one foldable anchoring leg aimed at anchoring the upstream support element to the patient's heart by cooperating with some patient's heart tissue, and at least one fixation means aimed at securing the upstream extremity of the pump body,
• a downstream support element, aimed at securing the exit cylinder to the patient's heart, the downstream support element displaying a general cylindrical shape with an inner diameter and an outer diameter, the inner diameter being sized to accommodate the exit cylinder in order to radially cooperate with said exit cylinder, and the outer diameter being sized to accommodate at least one tubular shaped part of the patient's heart in order to radially cooperate with said at least one tubular shaped part,
• wherein the upstream support element and the downstream support element are two independent and autonomous functional elements,
• wherein the upstream support element and the downstream support element are aimed to removably secure the assist device inside the patient's heart.

A support system delivery system comprising:

• an introducer comprising an external handle connected to a sheath divided in a proximal flexible sheath portion and a distal bendable steerable sheath portion, the distal bendable sheath portion being controlled by the external handle,
• a catheter comprising a handle connected to a proximal flexible catheter part further connected to a distal very flexible catheter part,
• a support system according to claim 1,
• wherein the introducer and the catheter are both designed to be easily introduced and navigated in a safe and controlled way through tortuous and narrow tubular lumen or tubes,
• wherein the catheter is designed to be navigated through the sheath of the introducer, wherein the distal part of the catheter is aimed at receiving either the downstream support element or the upstream support element.
