All or a portion of a surface of an implantable sensor is covered with a biocompatible coating formed at least partially of a biomaterial matrix having properties that promote a substantially even growth of tissue cells over the surface of the coating. Additional materials, such as growth factors, agents that recruit endogenous stem cells, and cell adhesion motif arginine, glycine, aspartic acid may be included in the coating. Autologous cells may be added to the coating prior to implantation. The sensor surface may also be textured, by etching or abrading, in order to promote even tissue growth. Alternatively, the sensor surface may be covered with a coating having properties that inhibit the growth of tissue. These coatings may include a biomaterial, a biomaterial matrix having a drug, such as a sirolimus or a steroid, an active component, or a self assembled monolayer.

Implantable sensor with biocompatible coating for controlling or inhibiting tissue growth

A method and device are disclosed for treating congestive heart disease. The material of the device is secured to the heart proximate the septal wall. The material covering the ventricles may or may not have the same tension and or compliance. The device can be constructed as a unitary 'jacket' that is slipped over the apex of the heart. Alternately, the device implanted as one, two or more separate components. In one embodiment, the material covers both the left and right ventricles. In another embodiment, the material covers only one ventricle. The device may include at least one adjustment mechanism configured to adjust the tension of the material. Preferably, the device includes a first adjustment mechanism configured to adjust a tension of the material covering the right ventricle and a second adjustment mechanism configured to adjust the tension of the material covering the left ventricle such that the tension of the material covering the left ventricle can be different than the tension of the material covering the right ventricle.
