<p>A biodegradable heart muscle implant is disclosed for use in plugging perforations made in a heart muscle to stimulate revascularization of damaged heart muscle regions or tissue sites. The heart muscle implants can be used directly to perforate the heart. A suturing material is also disclosed for use in heart muscle to promote or stimulate revascularization of damaged heart muscle regions or tissue. The implants and the suture materials all include impermeable portion(s) that are designed to be associated with the surface of the heart muscle and extend into the heart muscle a distance sufficient to reduce or eliminate fluid flow from the interior of the muscle. The portions that reside in the interior of the heart muscle are designed to be permeable to fluid flow and cell permeation and to act as a scaffold for revascularization of damaged heart muscle tissue.</p> |
