    摘要: The present invention relates to the direct delivery of therapeutic to a target tissue. In one embodiment a method for direct injection of plug forming material into a body tissue is provided. The method may comprise providing a catheter including a injection tube having a first channel, a second channel and a piercing tip. The first and second channels can be in fluid communication with a pressure source and a plug forming material. The injection tube may be slidably positioned in a pressure apron and moved from a first position to a second position so that the piercing tip extends beyond the tissue-mating surface in the second position to deliver the plug forming material.

    摘要: A medical device and system capable of providing on-demand delivery of biologically active material to a body lumen patient, and a method of making such medical device. A first coating layer comprising a biologically active material and optionally a polymeric material is disposed on the surface of the medical device. A second coating layer comprising magnetic particles and a polymeric material is disposed on the first coating layer. The second coating layer, which is substantially free of a biologically active material, protects the biologically active material prior to delivery. The system includes the medical device and a source of energy, such as an electromagnetic or mechanical vibrational energy. When the patient is exposed to the energy source, the magnetic particles move out of the second coating layer and create channels therein through which the biologically active material can be released.

    摘要: A method for furnishing a therapeutic-agent-containing medical device is provided. The method comprises: (a) providing a reactive layer comprising a cross-linking agent on a medical device surface; and (b) subsequently applying a polymer-containing layer, which comprises a polymer and a therapeutic agent, over the reactive layer. The cross-linking agent interacts with the polymer to form a cross-linked polymeric region that comprises the therapeutic agent. Examples of medical devices include implantable or insertable medical devices, for example, catheters, balloon, cerebral aneurysm filler coils, arterio-venous shunts and stents.

    摘要: The present invention generally relates to a medical device for delivering a therapeutic agent to an internal portion of a patient's body. The medical device includes a shaft and a self-expanding delivery member in operative communication with the shaft. The delivery member is shaped from a porous material that is capable of releasing a therapeutic agent to an internal portion of a patient's body. The medical device further includes a therapeutic agent delivery lumen in fluid communication with the delivery member to fluidly connect the delivery member with a therapeutic agent source. A retention member may also be provided to selectively collapse the delivery member.

    摘要: A medical device with a therapeutic agent-releasing polymer coating. The medical device is provided by a method that comprises: (a) attaching at least one reactive species to a medical device surface, which reactive species leads to chain growth polymerization in the presence of monomer; (b) contacting the reactive species with at least one monomer species, thereby forming a polymer coating on the surface of the medical device; and (c) providing at least one therapeutic agent within the polymer coating. The therapeutic agent may be incorporated during formation of the polymer coating or after formation of the polymer coating. The at least one reactive species can comprise, for example, a free radical species, a carbanion species, a carbocation species, a Ziegler-Natta polymerization complex, a metallocene complex, and/or an atom transfer radical polymerization initiator. Alternatively, the medical device is provided by a process comprising: (a) immobilizing least one polymerization catalyst at a medical device surface, which polymerization catalyst leads to polymerization in the presence of monomer; (b) contacting the medical device surface with at least one monomer species, thereby forming a polymer coating at the surface of the medical device; and (c) providing at least one therapeutic agent within the polymer coating.
