|Heart Failure||Device: C-Pulse™ (Implantable Counterpulsation Therapy)||Phase 1|
Sunshine Heart Inc. is sponsoring a prospective, multi-center trial to assess the safety and provide indications for performance of the Sunshine Heart C-PulseTM System ("C-Pulse™").
The current need is for a counterpulsation device or method that is effective enough to make its application appealing as a long-term implant to a large number of patients and physicians. It must be simple and safe, with a straight-forward implant procedure, and with long-term measurable patient benefits. Further, it would be advantageous for the counterpulsation device to be smaller, easier to insert, ambulatory, disconnectable, and not in the bloodstream. Such a device may be more readily adopted by a wider group of cardiologists and surgeons, and be suitable for a wider group of people in NYHA Class III or IV heart failure. It is important to point out that a counterpulsation device is aimed to augment native heart function and is fundamentally different from total artificial hearts, left ventricular assist devices and heart transplants which are meant to be a total replacement or an alternative to the native heart. Thus, the counterpulsation device is considered non-obligatory and not life-supporting.
Sunshine Heart, Inc has proposed C-Pulse™, a novel ambulatory, non-obligatory, non-blood contacting extra-ascending aortic counterpulsation system. The C-Pulse™ System is designed to be implanted without the need for cardiopulmonary bypass or extensive dissection, to be able to be activated immediately, to augment heart function in a safe manner and to provide sustained relief from heart failure symptoms. It can be turned off safely, and similarly, in failure modes, is considered to have an associated low risk of death or disability, other than the recurrence of heart failure symptoms. C-Pulse™ is not an alternative to the heart, it is an augmentation device, and it does not preclude the use of therapies that provide full circulatory support such as heart transplantation or LVADs.
The C-Pulse™ System consists of a counterpulsation Cuff secured around the outside of the ascending aorta, the main blood vessel out of the heart. The Cuff and a heart signal sensing wire are attached to an external driver. The external Driver inflates and deflates the Cuff in sequence with the ECG signal to assist heart function and improve the pumping capacity of the heart. The Cuff deflects the aorta in a "thumb-printing" manner which has been optimized to minimize aortic wall strain and maximize blood volume displacement per beat. The C-Pulse™ System is non-blood contacting, simple to insert, and can be turned on and off as required; all natural blood pathways are maintained - there is no exposure of foreign material to the bloodstream.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||20 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||C-Pulse Implantable Counterpulsation Pump (ICP) Feasibility Study - A Heart Assist System|
|Study Start Date :||December 2008|
|Actual Primary Completion Date :||October 2011|
|Actual Study Completion Date :||October 2012|
Active Comparator: Implantable Counterpulsation Therapy
The study is a single arm study with 20 patients being treated with implantable counterpulsation. Patients that meet eligibility will be enrolled and implanted into the treatment arm of the study. These patients will receive the C-Pulse System Implant as intervention therapy. There is not a control arm in this feasibility study.
Device: C-Pulse™ (Implantable Counterpulsation Therapy)
Implantation and activation of counterpulsation therapy for the full duration of the study period. The device may be turned off briefly for personal hygiene, etc.
- The safety will be evaluated by reviewing a composite of the device-related adverse events through six months, as classified by the CEC. [ Time Frame: Through 6 months ]
- The efficacy will be evaluated by assessing: Peak VO2, MLWHF, NYHA, 6MHW [ Time Frame: Through 6 months ]
