    Abstract: This is a method and an apparatus for the introduction of therapeutic compounds into tissue, particularly cardiac tissue. The apparatus includes a catheter having an elongated flexible body and a tissue infusion apparatus including a hollow infusion needle configured to secure the needle into the tissue when the needle is at least partially inserted into the tissue to help prevent inadvertent removal of the needle from the tissue. This permits the selected therapeutic compound to be delivered to a specific site. The catheter may also include a visualization assembly including a transducer at the distal end of the body.

    Abstract: A mitral annuloplasty and left ventricle restriction device is designed to be transvenously advanced and deployed within the coronary sinus and in some embodiments other coronary veins The device places tension on adjacent structures, reducing the diameter and/or limiting expansion of the mitral annulus and/or limiting diastolic expansion of the left ventricle. These effects may be beneficial for patients with dilated cardiomyopathy.

    Abstract: Medical devices, systems and kits for filling tissue are disclosed. The device has a first configuration wherein the device can pass through a small catheter or needle placed in the tissue to be filled and a second configuration in which the device is expandable to a predetermined or customizable shape. In one application, the device is adapted to be placed into the skin to reduce facial wrinkles or augment facial features such as the lips. Kits and systems include multiple device sizes, filler tubes, and filler media.
