A medical device delivery system including a delivery sheath that includes an internal lumen, and a plurality of delivery arms contained within the internal lumen of the delivery sheath and extending along a longitudinal axis of the internal lumen of the delivery sheath, wherein distal ends of the delivery arms include fasteners configured to engage with a basal structure of a medical device and a apical structure of the medical device, wherein the delivery arms are attached to delivery arm controls that are configured to advance the delivery arms and the medical device attached thereto out from a distal end of the delivery sheath, and removable release wires or release lines configured to engage with the fasteners to hold the basal structure and the apical structure in place at the fasteners. Also disclosed are methods of delivering a medical device to a subject including inserting a distal end of the medical device delivery system through an incision in the skin of subject, and deploying a medical device engaged with the delivery arms of the medical delivery system to within the body of the subject.

A system and method for evaluating, altering and/or creating an opening around the heart to receive a construct. Using a minimally invasive techniques, a first guide is advanced into an area adjacent to the heart. The first guide is used to probe the area and determine if an opening can be safely formed in that area. The guide is then used to direct a larger guide catheter into the targeted area. The larger guide catheter is used to direct a more robust guide into the targeted area. The robust guide is then used to direct a delivery guide catheter into the targeted area. The delivery guide catheter can be used to stall. a device deployment guide. Either the delivery guide catheter or the device deployment guide can be used to advance the construct into the targeted area.

This medical system of the present invention could help in diagnosis as well as treatment of the heart failure and other myocardial diseases to improve the condition of patient. It could also be helpful for the monitoring, diagnosis and treatment of diseases of lungs, kidney, liver, spleen, stomach and bladder, etc.

The present invention provides methods, systems, kits, and cardiac compression devices that have both passive chambers and active chambers to improve heart function.

An implantable heart help device adapted for implantation in a human patient is provided. The device comprising a fixating member adapted to fixate said device to a part of the human body comprising bone. Further a method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.

The present invention relates to an implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle, said device comprising at least one pump device comprising: a first part having a first surface, and a second part having a second surface. The first part is displaceable in relation to the second part and said first and second surfaces abut each other, at least partially. The second part exerts, directly or indirectly, force on an external part of said heart muscle.

A medical device including an artificial contractile structure, which may be advantageously used to assist the functioning of a hollow organ, is provided. The medical device includes an artificial contractile structure including at least one contractile element adapted to contract an organ in such a way that the contractile element is in a resting or in an activated position; at least one actuator designed to activate the contractile structure; and at least one source of energy for powering the actuator. The actuator includes an electromotor and a transmission element linking the electromotor to the contractile element, the transmission element being configured to transmit to the contractile element a force induced by the electromotor. The electromotor includes an electric motor, a gear head connected to the motor, a lead screw cooperating with a nut mounted on the lead screw, the lead screw or the nut being connected to the transmission element and cooperating with the gear head to transmit the force induced by the electromotor on the transmission element. The ratio current which is needed to maintain the contractile element in its activated position/current which is needed to change the position of the contractile element is less than 1/500.

A system and method for determining the proper dynamic strain profile of an elastomeric construct. The strain characteristics of a deficient heart are determined and compared to the normal strain characteristics of a healthy heart. A construct having elastomeric elements is provided that can expand along multiple axes. In an unloaded condition remote from the deficient heart, the elastomeric elements are pressurized to determine the pressure differential being experienced. Furthermore, optimal strain characteristics are calculated along a first axis and a second axis as a function of the pressure differential. The first optimal strain characteristic and the second optimal strain characteristic are used to estimate the dynamic strain characteristics that will be applied to the heart. The dynamic strain characteristics are compared to the optimal strain characteristics required by the heart to determine if the construct is proper using an automated drive.
