20110213451 | MEDICAL DEVICE SHIELD AND METHODS FOR DELIVERING A MEDICAL DEVICE - Device shields for packaging and protecting medical devices during storage and deployment. A device shield includes a housing configured to maintain a medical device and at least a portion of a medical device delivery apparatus within the housing, and a limit element having a first constraining position and a second open position. | 09-01-2011 |
20110288622 | EXPANDABLE ENDOPROSTHESES, SYSTEMS, AND METHODS FOR TREATING A BIFURCATED LUMEN - An endoprosthesis for treating a bifurcated lumen. The distal end of the endoprosthesis can include at least two wings and at least two troughs so the endoprosthesis can adequately scaffold the ostium of a bifurcated lumen by at least partially straddling the carina of the lumen bifurcation. The distal end of the endoprosthesis can also be configured to have increased expandability to help allow conformity to the anatomy of a bifurcated lumen. | 11-24-2011 |
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 |
20120065719 | MEDICAL DEVICE SHIELD AND METHODS FOR DELIVERING A MEDICAL DEVICE - Device shields for packaging and protecting medical devices during storage and deployment. A device shield includes a body or housing configured to maintain a medical device and at least a portion of a medical device delivery apparatus within the body or housing, and a limit element having a first constraining position and a second open position. | 03-15-2012 |
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 |
20140163601 | E-SPUN MEDICAL BALLOON HAVING VARIED THICKNESS AND METHODS FOR FORMING SAME - The disclosed subject matter describes systems and methods of electrospinning a fiber for a variety of applications. An exemplary embodiment includes a medical device application for delivering a therapeutic agent, such as a sclerosing agent, to the walls of a blood vessel to perform sclerotherapy. A method of fabricating a medical balloon comprises charging a polymer material with an electric voltage, dispensing the charged polymeric material through a nozzle, collecting the charged polymeric material on a grounded mandrel, wherein the mandrel includes a tubular body having a plurality of openings extending through the tubular body, and forming an electrospun medical balloon defined by a body having a varied thickness. | 06-12-2014 |
