Flexible vascular inducing implants
First Claim
1. An implant device comprising a flexible body formed from a single wall, which defines an interior with a volume, the flexible body constructed to have a first configuration having a first profile and a first volume and a second configuration that is compressed to define a second profile that is different from the profile of the first configuration, and a second volume that is substantially reduced from the first volume, the implant constructed so that movement of surrounding tissue in which it is implanted causes cyclical movement of the body between the two configurations.

Abstract
Implants and associated delivery systems for promoting angiogenesis in ischemic tissue are provided. The implants may be delivered percutaneously, thoracically or surgically and are particularly well suited for implantation into the myocardium of the heart. The implants are configured to be flexible so that they compress and expand with corresponding movement of the surrounding tissue into which they are implanted. The flow of blood into the implant and pooling of the blood in and around the implant leads to thrombosis and fibrin growth, a healing process that leads to angiogenesis in the tissue surrounding the implant. Additionally, the implants may contain an angiogenic substance or a thrombus of blood, preloaded or injected after implantation to aid in initiating angiogenesis.

25. An implant for implantation in the myocardium of a patient comprising;
- a flexible body formed from a single wall of flexible material defining an interior and at least one opening to the interior, and the body being configured to pump blood into and out of the interior under the influence of the contraction and relaxation of the myocardial tissue into which it is implanted and the interior configured to promote thrombosis of entering blood.

26. A device for promoting angiogenesis in the myocardium comprising:
a carrier having a single wall defining a pump with a chamber implantable in the myocardium and having associated with it an angiogenic substance. - View Dependent Claims (27, 28)
