摘要： Everting balloon systems and methods for using the same with an alignment element for stability and anti-rotation of the everting balloon are disclosed herein. The systems can be configured to access and deliver instruments, media, or other catheters into bodily lumens and cavities. The alignment element eliminates the potential for the everting membrane to become twisted or rotated which could impact access or the ability of the system to deliver materials. A compliance member facilitates internal pressurization of the everting catheter system.

摘要： A catheter assembly includes a catheter at least partially positioned within a sleeve. The catheter has a coating, which produces a low-friction surface on the catheter when treated with an activating fluid. A protective tip is connected to the sleeve and has proximal and distal internal seals, with the proximal seal at the proximal end of the tip or between proximal and distal ends of the protective tip. A cap of the assembly has a projection, which is removably received within the protective tip for sealing engagement with the proximal and distal seals to define a fluid reservoir within the protective tip. An activating fluid is contained within the fluid reservoir. The projection may be partially hollow to receive a portion of the catheter. The sleeve may be relatively narrow or at least have a narrowed portion for better distribution of activating fluid to the surface of the catheter.

摘要： The present invention provides a flexible catheter system and method for providing easier access and delivery of therapeutics and or devices via the human vasculature. The flexible catheter system comprises a luer connector attached to a flexible catheter body by a proximal shaft. The method includes the steps of providing a patient in need of an interventional procedure, obtaining a flexible catheter system, inserting the flexible catheter system into the patient through the right radial artery located in the right arm of the patient, and tracking the flexible catheter body from the right radial artery to the heart of the patient.

摘要： Package (10) for holding an intermittent, male urinary catheter (1). The package (10) has a vessel (5) which is tubular in shape allowing the urinary catheter (1) to be movably arranged in an inner volume of the vessel (5). An enveloping housing of the package entirely encloses the urinary catheter (1) when packaged. The enveloping housing has three tubular parts (2, 3, 6) of which a first and second straight part (2, 3) are of a hard plastic material, and a third part (6) is of a flexible material. The first straight (2) part is closed off at a bottom end thereof and the second straight part (3) is closeable by the cap (4) and comprises the vessel (5).

摘要： A catheter having a selectively variable degree of flexibility includes an elongate tubular outer member and an elongate tubular inner member disposed within the outer member. The catheter further includes a cavity disposed in between the outer and inner members. A tubular braid of filaments may be disposed within the cavity. The outer and inner members are movable relative to each other along intermediate portions thereof when in a first configuration, and are not movable relative to each other when in a second configuration. When the inner and outer members are in the first configuration, the tubular braid of filaments is movably disposed relative to at least one of the outer member and the inner member. When the inner and outer members are in the second configuration, the inner and outer members clamp the tubular braid of filaments in a fixed position relative to the inner and outer members.

摘要： Configurations are described for assisting execution of a percutaneous procedure while protecting the vascular pathway to the operational theater. One embodiment is directed to a system for deploying a device to a distal location across a diseased vessel, comprising a sheath comprising an expandable distal portion comprising a porous wall defining a lumen therethrough, the distal portion having a collapsed configuration, wherein the sheath has a first cross sectional outer diameter and a first lumen inner diameter, and an expanded configuration, wherein the sheath has a second cross sectional outer diameter and a second lumen inner diameter; wherein in the collapsed configuration, the sheath is configured to be advanced across at least a portion of the diseased vessel to a position adjacent the distal location without substantial size interference between the first cross sectional outer diameter of the sheath and an inner diameter profile of a lumen of the vessel.
