    摘要: A device and method for delivering and injecting fluid into heart tissue utilizing a laterally directed needle to increase injectate (fluid) retention in the heart tissue. The device may comprise a catheter having a shaft wherein the distal end of the shaft includes a primary penetrating member and a secondary penetrating member. The secondary penetrating member includes an injection lumen in fluid communication with a pressurized fluid source. The primary penetrating member penetrates the heart tissue at the injection site in a first direction, and the secondary penetrating member penetrates the heart tissue in a second direction different from the first direction such that fluid leakage from the injection site is reduced and the volume of treated tissue is increased.

    摘要: A catheter for delivering therapeutic to an injection site within the body is provided. This catheter can include a shaft having a proximal end, a distal end, and an infusion lumen extending therein; a penetrating member coupled to the shaft and extendable from the distal end of the shaft, and a stabilizer positioned towards the distal end of the shaft. The catheter could also include a delivery system, able to be calibrated to deliver therapeutic through an injection port at a rate less than the therapeutic absorption rate of the injection site.

    摘要: This invention relates generally to medical devices, such as stents, for delivering a biologically active material to a desired location within the body of a patient. In particular, the invention relates generally to a medical device for delivering a biologically active material to a surface of a body lumen. More particularly, the invention is directed to a medical device comprising two opposing end sections, each having a surface, and a middle portion. The middle portion comprises a plurality of struts and the two opposing end sections comprises non-structural elements. The end sections of the surface either (1) contain a greater amount of a biologically active material per unit length of the surface or (2) have a greater capacity per unit length to contain such material than the middle section of the surface by having a greater surface area per unit length of the surface than the middle section or having a greater affinity for the biologically active material per unit length of the surface than the middle section. The struts and the non-structural elements comprise biologically active materials. The invention is also directed to a method for delivering the biologically active material to the body tissue of a patient by inserting this medical device into the body of the patient. Still further, the invention is directed to a method of treating a body lumen surface by preventing or treating restenosis or hyperplasia, using the system of the invention. Still further, the invention is directed to a stent having a sidewall which comprises a middle section, a first end section and a second end section. The stent also comprises a band comprising a biologically active material. The band is connected to the first end section and/or second end section of the stent.

    摘要: In one embodiment of the present invention a coating topology, or engineered surface architecture that may be referred to as a microdroplet deposited engineered surface architecture is provided. A plurality of drops are placed on the stent with the purpose, of building up individual units of coating material on the outer stent surface. This architecture results in a coating that uses less material, i.e., polymer, solvent, medicine, while at the same time providing for better, and determinable, drug kinetics, approaching 100% delivery and better mechanical operation of the coating binding to the stent.
