Publication number: 20040249408Abstract: Embodiments disclose a method for repairing a heart of a human. A method may include introducing a collapsed reinforcing element through the skin into the vascular system of the human. The method may include delivering the reinforcing element into a left ventricle through the arteries. Once inside the left ventricle, the reinforcing element may be expanded to an expanded shape. In certain embodiments, a reinforcing element may be used to structurally reinforce a portion of an endocardial surface of a heart. The reinforcing element may include a preshaped patch and/or a plurality of preshaped flexible conduits. The method may include deploying the reinforcing element soon after a myocardial infarction to inhibit naturally occurring remodeling of the heart. The reinforcing element may be deployed with or without the use of a shaper. In some embodiments, a reinforcing element may include an externally positioned apparatus configured to substantially reshape a portion of an interior chamber of a heart.Type: ApplicationFiled: September 5, 2002Publication date: December 9, 2004Applicant: Chase Medical, LPInventors: Gregory Murphy, Mitta Suresh, Albert Davis
