    摘要: The invention relates to multi-layer medical balloons. In one aspect, a medical device includes an inflatable balloon. The inflatable balloon includes a first layer including a material having a first modulus of elasticity, and a second layer adjacent the first layer, the second layer including a material having a second modulus of elasticity that differs from the first modulus of elasticity by at least about 2,000 psi. A cutting element is carried by the balloon.

    摘要: A valve having a first housing including a first lumen extending therethrough and a first disk-facing surface, a second housing including a second lumen extending therethrough and a second disk-facing surface, where the second housing is coupled to the first housing so that the second disk-facing surface faces the first disk-facing surface. A flexible disk has at least a portion of an outer edge of the disk extending away from a plane of a central portion of the disk, the outer edge contacting the first disk-facing surface, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a threshold level opens to permit fluid flow between the first and second lumens and which, when acted upon by a fluid pressure less than the threshold level, prevents fluid flow between the first and second lumens.

    摘要: A vascular access catheter is disclosed that has a catheter shaft with a distal end portion with a distal tip having a sloped face that is positioned at an acute angle from the distal tip relative to a longitudinal axis of the catheter shaft. A first, second, and third lumen extend longitudinally through the catheter shaft. The third lumen is configured for receiving a guidewire and may extend a partial length of the catheter or substantially the entire length of the catheter. The first lumen has an aperture located in the angled edge distal end portion of the catheter next to the distal tip and communicates with the first lumen. The second lumen has an aperture that is positioned in the outer surface of the catheter shaft that is in communication with the second lumen, and is spaced proximally from the first lumen aperture. The catheter includes a fluoropolymer additive with specific compositions and/or purity levels.

    摘要: A catheter that comprises a hub, an elongated conduit, and at least one lumen therein. The lumen includes a proximal lumen section, a distal lumen section, and an intermediate lumen section extending between the proximal and distal lumen sections. The cross-sectional dimension of the intermediate lumen section is less than the cross-sectional dimension of the distal lumen section. In one embodiment, the cross-sectional dimension of the intermediate lumen section is less than the cross-sectional dimension of the proximal lumen section. In certain embodiments, the lumen tapers from the distal and/or proximal lumen sections to the intermediate lumen section.
