摘要： The present invention is directed to novel, less invasive and improved methods of tissue-engineering of constructs that require an endothelial surface such as blood vessels and heart valves. The constructs of the present invention possess long-term patency. The method of the present invention is particularly suited for making small diameter vessels to replace clogged or damaged coronary blood vessels, for making trileaflet heart valve conduits to replace damaged or malformed pulmonic and aortic valves, and for other vascular structures that require an endothelial surface.

摘要： Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned.

摘要： A method, and related tools for performing the method, of delivering a stent or other like device to the heart to connect the left ventricle to the coronary artery to thereby supply blood directly from the ventricle to the coronary artery may be used to bypass a total or partial occlusion of a coronary artery. The method may include placing a guide device and a dilation device through an anterior wall and a posterior wall of the coronary vessel and through a heart wall between the heart chamber and the coronary vessel. The dilation device may be used to form a passageway in the heart wall at a location defined by the guide device. The method may then include placing a stent within the passageway.

摘要： The present invention relates to a delivery system for a self-expanding stent. The delivery system comprises an inner member having a distal end, the inner member being configured to retain a self-expanding stent proximate the distal end, the inner member including a first marker band (64) such that, when the self-expanding stent is retained proximate the distal end, the first marker band (64) is disposed between a distalmost leading end of the self-expanding stent and a trailing end of the self-expanding stent, wherein the marker band indicates a reconstrain limit of a partially-expanded, self-expanding stent; an outer member positioned about the inner member, the outer member being slidable relative to the inner member in an axial direction; a holding sleeve positioned such that, when the self-expanding stent is retained proximate the distal end, the holding sleeve is within an interior of the stent and cooperates with the outer member so as to retain the positioning of the stent; and an inflatable device positioned about the inner member, wherein the inflatable device is disposed between the holding sleeve and the distal end of the inner member.

摘要： An endolumenal device (1) for delivering and deploying an endolumenal expandable prosthesis (6) at a bifurcation provided with a main conduit and at least a secondary conduit, comprises an elongated body (2) having a proximal end portion (4) and a distal end portion (3); the distal end portion (3) comprising expansion means (5) having a longitudinally extended active portion removably engageable with the prosthesis (6). Said active portion of the expansion means is longitudinally associated to the body in order to expand said prosthesis eccentrically from one side with respect to the body, in order to leave free from said expanded active portion the other side of the body. The device further is provided with guidewire tracking means (11).

摘要： The invention relates to a method for decellularising allogenic and xenogenic foreign material for the subsequent production of bioprostheses, coated with endogenous body cells, whereby the foreign material is firstly treated in a solution of bile acid and then alcohol, each with an intermediate or subsequent rinsing step, in combination with a mechanical action on the tissue and the cells by the force generated from a flowing treatment medium, at least in the final rinsing step. After said treatment the tissue is completely rid of foreign cell material and viruses and represents an excellent starting material for the coating with cells of the bioprosthesis recipient.

摘要： Porous polymers having a plurality of openings or chambers that are highly convoluted, with each chamber being defined by multiple, thin, flat partitions are produced by a new gel enhanced phase separation technique. In a preferred embodiment, a second solvent is added to a polymer solution, the second solvent causing the solution to gel. The gel can then be shaped as needed. Subsequent solvent extraction leaves the porous polymeric body of defined shape. The porous polymers have utility as medical prostheses, the porosity permitting ingrowth of neighboring tissue. A second polymer material may be incorporated into the chambers, thereby creating a microstructure filling the voids of the macrostructure. A porous polymeric body manufactured by this process may serve to deliver biologically active agents in a time-staged delivery manner, where differing drugs may be delivered over differing periods.

摘要： The present invention provides improvements in methods for the manufacture of stents. Specifically, the invention provides methods wherein stents are placed on jigs of various designs which facilitate manufacture, stents carried by the jigs are immersed in liquid baths which contain an electrolyte, the stents are urged into contact with their associated electrodes while current is applied to those electrodes, and wherein the positions of contact between the stents and their respective electrodes are altered during processing without removing the stents from the jig. The method is applicable for electropolishing and electroplating.
