摘要： Methods are provided for the fabrication of microneedles. Microneedles fabricated according to the herein described methods will generally be constructed of multiple lengths of wire winded together, brazed and further manipulated to include a reversible engagement feature. The subject microneedles may find use in a variety of applications and, among other purposes, the reversible engagement feature of such a microneedle may by employed in implanting an implantable device into a biological tissue. Also provided are methods of inserting an implantable device into a biological tissue having an outer membrane. The subject methods may include ablating a section of the outer membrane and inserting the implantable device through the ablated section of outer membrane, including e.g., where the implantable device is inserted using a microneedle including e.g., those microneedles for which methods of fabrication are provided herein.

摘要： A method of making a self-expanding stent entails applying a bend stress sufficient to over-bend a portion of a wire by an amount in a range from about 85% to about 105%, where the wire comprises a Ni—Ti alloy and includes from about 40% to about 46% cold work. The bend stress is then released, thereby forming a bend having a predetermined bend angle in the wire. The application and release of the bend stress are repeated on successive portions of the wire in order to create a series of bends along a length of the wire in a predetermined bend pattern. The wire comprising the predetermined bend pattern is then positioned about a mandrel in an expanded stent geometry and heat set. Thus, a self-expanding stent is formed.

摘要： A guide wire has an elongated core portion, a resin coating layer including a resin material and covering a distal portion of the core portion, and a metallic tubular member that has a lumen into which the core portion is inserted, and that is disposed so as to be in contact with at least a portion of a proximal end of the resin coating layer. The tubular member is formed in a state where the lumen is reduced in diameter by cold forging, and at least a portion of an inner surface forming the lumen has a compressive bonding surface which is compressively bonded to an outer surface of the core portion.

摘要： The invention provides a novel method for producing a composite member by fixing a surface member to the outer peripheral surface of a core member. A method for producing a composite member having a core member and a surface member fixed to the outer peripheral surface of the core member includes the surface member providing step of providing the surface member having magnetism lower than magnetism of the core member made of a conductive material on the outer peripheral surface of the core member, and the fusing step of electromagnetic induction heating the core member from outside the surface member to melt at least one of facing regions between the surface member and the core member with heat of the heated core member and fuse the surface member to the core member.

摘要： A method of a forming a hollow, drug-eluting nitinol stent includes shaping a composite wire into a stent pattern, wherein the composite wire includes an inner member, a nitinol intermediate member, and an outer member. After the composite wire is shaped into the stent pattern, the composite wire is heat treated to set the nitinol intermediate member in the stent pattern. After heat treatment, the composite wire is processed to remove the outer member and the inner member without adversely affecting the intermediate member. Openings may be provided through the intermediate member and the lumen of the intermediate member may be filled with a substance to be eluted through the openings.

摘要： A method for forming a wave form for a stent includes moving a first forming portion of a first forming member across an axis along which a formable material is provided in a first direction substantially perpendicular to the axis to engage and deform the formable material while engaging the formable material with a first forming portion of the second forming member. The method includes moving the first forming portion of the first forming member and the first forming portion of the second forming member across the axis in a second direction that is substantially opposite the first direction to draw and form the formable material over the first forming portion of the second forming member, disengaging the first forming member from the formable material, and rotating the first forming member to position a second forming portion of the first forming member to face the formable material.
