    摘要： Guidewire-management devices and systems thereof are disclosed herein. A guidewire-management device can include a guidewire, a first sleeve, and a second sleeve. The first sleeve can be configured for distally feeding the guidewire out of the guidewire-management device. The first sleeve can also be configured for proximally feeding the guidewire into the guidewire-management device. The second sleeve can be proximal of the first sleeve in the guidewire-management device. The second sleeve can be configured for feeding the guidewire in concert with the first sleeve. At least a length of the guidewire extending between the first sleeve and the second sleeve can be disposed within a sterile barrier configured to maintain sterility of the guidewire.

    摘要： A guide wire includes an elongated wire body having flexibility; a distal member that covers a distal portion of the wire body and is configured to have a resin material; and a hydrophilic lubricant layer that is formed so as to cover a proximal end of the distal member and is configured to have a hydrophilic material. In addition, the hydrophilic lubricant layer has a tapered shape whose outer diameter gradually decreases toward a proximal side. In addition, the maximum outer diameter of the hydrophilic lubricant layer is smaller than the maximum outer diameter of the distal member. In addition, a proximal portion of the distal member has a tapered shape whose outer diameter gradually decreases toward the proximal side, and a distal end of the hydrophilic lubricant layer is positioned at the tapered portion of the distal member.

    摘要： A medical device for guiding through anatomy, such as a catheter or guidewire, with a tubular body that has been slotted to enhance bending flexibility, and a polymer liner with an anti-collapsing structure, and a method of making a medical device with a kink-resistant corrugated tubular member and an anti-collapsing structure. Anti collapsing structures may be helical or annular, and may be wire, such as ribbon wire, grooves in the liner, corrugations, or a braid. Liners may be bonded to the anti-collapsing structure, or may have two layers, with the anti-collapsing structure between the layers. Corrugations may be formed between sections of the anti-collapsing ‘structure with heat, pressure, stretching, compression, a mold, or a combination thereof, and may extend inward or outward. Shape or wall thickness may vary along the length to provide a varying bending stiffness. Slots may be formed in groups of two, three, or more, and adjacent groups may be rotated about the axis forming a helical pattern.

    摘要： A medical device includes a coil having a longitudinal axis and a radial axis orthogonal to the longitudinal axis, formed from a wire. The wire includes a cross-section with a centroid, a moment of inertia with respect to an axis running through the centroid and parallel to the longitudinal axis of the coil, and a moment of inertia with respect to an axis running through the centroid and parallel to the radial axis of the coil. The moment of inertia with respect to an axis running through the centroid and parallel to the longitudinal axis of the coil is greater than the moment of inertia with respect to an axis running through the centroid and parallel to the radial axis of the coil.

    摘要： An elongate tubular body is disclosed, such as for use in medical applications. The body comprises a spring coil having at least one central lumen extending axially therethrough, for receiving medical implements, fiber optics, suction or transmission of fluids such as for irrigation or drug delivery. An elastomeric outer layer on the spring coil provides a substantially water impermeable seal. A distal tip may be integrally formed with the elastomeric outer layer.
