20120041257 | APPARATUS AND METHODS FOR SUPPORTING CARDIAC ISCHEMIC TISSUE - Apparatus and methods are disclosed for supporting ischemic tissue of the heart using scaffolds that may be placed within the heart percutaneously. A scaffold assembly may include a layer of biocompatible material detachably secured to a placement rod, such that the placement rod may be used to urge the layer of biocompatible material through a catheter to adjacent an area of ischemic tissue. Anchors may secure the layer of material to the myocardium. Multiple layers of biocompatible material may be placed in the ventricle separately to form the scaffold. In some embodiments, a scaffold is formed or reinforced by injecting a polymer, such as a visco-elastic foam, around an inflatable member inflated within a ventricle. | 02-16-2012 |
20120190918 | APPARATUS AND METHODS FOR SUPPORTING CARDIAC ISCHEMIC TISSUE BY MEANS OF EMBEDDED STRUCTURES - Systems and methods are disclosed for reinforcing ischemic tissue of a heart. A reinforcing element is initially positioned within a lumen of a delivery needle. The delivery needle is urged into the ischemic tissue and the reinforcing element is urged out of the needle into the ischemic tissue. The reinforcing element may be embodied as a coiled, undulating, or arcuate spring and may include a shape-memory material. A bioabsorbable material may maintain the reinforcing element in a deformed state. The reinforcing element may be tensioned as it is positioned within the myocardium in order to provide a cinching force by means of a cord lock selectively releasing the reinforcing element. The reinforcing element may be embodied as a number of spiral portions secured to a hub and urged outwardly by rotation of the hub. | 07-26-2012 |
20130138081 | METHOD AND MEDICAL DEVICE HAVING TISSUE ENGAGING MEMBER FOR DELIVERY OF A THERAPEUTIC AGENT - Method of delivering a therapeutic agent includes delivering at least a portion of a medical device within a vasculature. The medical device includes a tubular member having a proximal end and distal end defining a longitudinal axis therebetween, an expandable member proximate the distal end of the tubular member, a tissue engaging member proximate the expandable member, a sheath disposed over the tissue engaging member, and a therapeutic agent disposed on at least the expandable member or the tissue engaging member. The method further includes deploying the tissue engaging member at a select location by displacement of the sheath relative the tissue engaging member, inflating the expandable member to engage the therapeutic agent with a vessel wall, deflating the expandable member, and withdrawing the medical device from the vasculature. | 05-30-2013 |
