ABSTRACT:
A synthetic intraventricular implant device adapted to be surgically secured in a ventricle of the heart of a patient. The shape, size and volume of the device so inserted will depend on the size of the ventricle of the patient, and how much of the end-diastolic volume thereof it is desired to reduce. The device is surgically inserted into and secured in place in the ventricle by suturing it onto a preselected segment of the interior wall of the ventricle to reduce end-diastolic volume, pressure and wall stress, and to subsequently increase ejection fraction and cardiac output. The device may include a fluid, liquid, semi-liquid, semi-solid, solid or viscous core and/or an inflatable balloon-like portion for use in assisting in the elimination of blood from the "dead volume" within the ventricle. Additionally, the inflatable implant, when used as a ventricular assist device, will increase the ejection fraction and contractility of the myocardium, as well as cardiac output, either permanently or temporarily, in some patients with specific cardimoypathies.
An implant device is inserted during open heart surgery on a patient, by forming an opening in a portion of the distal end wall of a ventricle of the patient's heart, inserting the selected implant into the interior chamber of the ventricle, suturing the implant in a predetermined position against a segment of the interior wall within the patient's ventricle and suturing the opening made in the distal end wall of the ventricle. Revascularization or associated procedures may follow or proceed insertion of the implant.
