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： A medical device system that is insertable in a body lumen for treating and/or preventing injury to a body lumen wall is disclosed. The system comprises a stent comprising a sidewall having a first edge and a second edge, and a balloon capable of being disposed within the sidewall. The balloon has a first end portion that is capable of contacting the first edge of the sidewall and a second end portion that is capable of contacting the second edge of the sidewall when the balloon is expanded. At least the first end portion of the balloon comprises a first biologically active material. When the balloon is expanded, the first end portion of the balloon extends axially beyond the first edge of the sidewall in order to deliver the first biologically active material to a portion of the body lumen wall that is adjacent to the first edge of the sidewall. Methods for deploying the system are also disclosed.

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.
