    摘要: Medical devices, and particularly intracorporeal devices for therapeutic or diagnostic uses, having a component chemically modified by plasma polymerization. The medical device comprises a substrate with a plasma polymerized functionality bonded to a surface of at least a section thereof. The plasma polymerized film on a first component of the medical device allows for bonding an agent or a second component to the first component. In one embodiment, the plasma polymerized film facilitates fusion or adhesive bonding of a first component to a second component formed of a material which is dissimilar to, incompatible with, or otherwise not readily bondable to the substrate material of the first component. In another embodiment, a bioactive agent is bonded to the plasma polymerized film on the component, for presenting or delivering the bioactive agent within a body lumen of the patient.

    摘要: A catheter having an multilayered shaft section with a first layer formed of a polyimide first material and a second layer formed of a second material. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. However, in alternative embodiments, a thermoplastic polyimide is used. The thermoset polyimide has a very high glass transition temperature (Tg) of approximately 400° C. (as measured by differential scanning calorimetry), and excellent dimensional stability at the processing temperature of polyamides commonly used in catheter components. As a result, during formation and assembly of the catheter, production of a thin polyimide layer with controlled dimensions is facilitated. The polyimide has a high modulus and provides a thin walled yet highly pushable shaft section, while the second layer provides kink resistance. In one embodiment, the second material is selected from the group consisting of a polyamide material and a polyurethane material.

    摘要: An infusion catheter and method, with an elongated shaft having a guidewire lumen which has a proximal section and a common distal section extending to a distal port at a distal end of the shaft, and an infusion lumen which is in fluid communication with the distal port of the guidewire lumen and which joins the common distal section of the guidewire lumen at a location distal to the guidewire proximal port. A restricted passage from the infusion lumen to the common distal section of the guidewire lumen has a smaller transverse dimension than the guidewire lumen and a guidewire slidably disposed in the guidewire lumen.
