Abstract
A myocardial implant for insertion into a heart wall for trans myocardial revascularization (TMR) of the heart wall. The TMR implant provides for means to promote the formation of new blood vessels (angiogenesis), and has a flexible, elongated body that contains a cavity and openings through the flexible, elongated body from the cavity. The TMR implant includes a coaxial anchoring element integrally formed at one end for securing the TMR implant in the heart wall.
Claims19
A myocardial implant for Trans Myocardial Revascularization in a portion of a heart wall, comprising, in combination:
