摘要： Medical devices that are formed from a polymeric matrix including a first polymer and a functionalized polymer are provided. The medical devices may include a functionalized polymer such as maleic anhydride functionalized polymer. The burst strength and/or the hoop strength of the medical devices including the functionalized polymer may be greater than the burst strength and/or the hoop strength of control medical devices. However, the durometer of the medical devices may be substantially equal to the durometer of the control medical devices. Methods of manufacturing medical devices including a functionalized polymer are also provided.

摘要： A balloon catheter includes a balloon which is both of high strength and radiopaque. The balloon includes an outer strengthened layer which includes a strengthening element at least partially embedded within the layer. Concentrically within the strengthened layer there is a radiopaque layer which includes a high concentration of radiopaque material distributed in the radiopaque layer. The strengthened layer acts as a support to the radiopaque layer which is otherwise be unable to withstand the pressure to which the balloon is normally inflated for deployment and in the course of a medical procedure. The structure provides a high strength radiopaque balloon with a relatively thin balloon wall optimizing balloon flexibility and wrappability. There is also disclosed a method of making a balloon which uses an internal support layer in a raw tubing which is then removed following formation of a balloon.

摘要： A venous access catheter shaft and method of using and manufacturing such a catheter is provided. In one aspect of the invention, a catheter is provided comprising a base polymer having a Shore A durometer of 85A or lower, with 2.0% percent by weight of surface modifier, and a radiopaque filler comprising between 20-40 percentage by weight. In another aspect of the invention, a method reducing thrombus accumulation on a venous access catheter is provided wherein the catheter surface's resistance to thrombus formation is enhanced during indwell time by lowering the durometer rating of the base polymer of the catheter without increasing the amount of surface modifier additive. In another aspect of the invention, a method of manufacturing a catheter shaft is provided, wherein the shaft is formed comprising a base polymer having a Shore A durometer of 85A or lower, with 2.0% percent by weight of surface modifier, and a radiopaque filler comprising 30% by weight barium sulfate, and optionally a colorant of 0.2% weight.

摘要： A medical device includes a structural element comprising an outer surface and a material on the outer surface of the structural element. The material defines void spaces containing a gas entrained within the void spaces. The material, upon contact with physiological fluid, is configured to release the gas in an amount sufficient for the gas to be imaged by ultrasound.

摘要： A medical device, such as a medical wire, which includes a coating applied to the surface of the medical wire. The coating includes a base layer bonded to the surface of the medical wire and an at least partially transparent low-friction top coat applied to the base layer. The base layer includes heat activated pigments that change color when heated above a color shifting temperature. In one embodiment, the color of the pigment in one area contrasts with the color of the pigment in an adjacent area without otherwise affecting the low-friction surface of the coating. The areas of different color created in locations along the length of the low-friction coated medical wire form markings which, as an example, enable a surgeon to determine the length of the medical wire inserted into a body by observing the markings on the portion of the marked medical wire located exterior to the body.

摘要： A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.
