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.

A medical device, such as a prosthesis, and method of forming the same are disclosed. The medical device includes a cover material and a reinforcement element, and may include a stent frame structure. The reinforcement element includes a plurality of bends disposed about a pattern axis. The pattern axis is arranged helically along the cover material.

A complex coil and a fixture for forming same configured such that loops are formed having various configurations relative to each other. The configurations provide improved thrombus formation and reduced rotation or tumbling once implanted. The complex coil is formed of a material that may deformed for purposes of placing the complex coil into a catheter and returns to a complex shape that includes said loops once deployed.

A wire feeding and bonding tool and method for attaching wires to a component having first and second spaced-apart wire attach structures. Wire from a supply is fed through a capillary having at least a linear end portion with a feed opening. The capillary is positioned with respect to the component to locate a first portion of the wire extending from the feed opening adjacent to the first wire attach structure, and the wire is attached to the first attach structure. The capillary is moved with respect to the component along a wire feed path to feed the wire from the first wire attach structure to the second wire attach structure and to locate a second portion of the wire extending from the feed opening adjacent to the second attach structure. The wire is attached to the second wire attach structure, and cut from the supply.

The present invention relates to a stent that uses a shape memory alloy wire, the stent being an expansion device installed on a part of a body lumen, which is constricted, or which has been constricted, so as to widen the passage of the lumen in response to the lesion part. The purpose of the present invention is to provide a method for manufacturing a stent using a shape memory alloy wire such that the stent maintains a high degree of conformability in a bent portion of a body lumen in which the same is inserted while substantially improving rigidness and durability against continuously applied fatigue, a stent manufactured thereby, and a jig for manufacturing the same.

A system and a method is provided in which a CAD system receives a solid model and receives user input to select points on the surface of the solid model, to create a wire part program file based on the selected points, and to transmit the wire part program file to a bending machine. The wire part program files is configured such that the bending machine will manufacture a wire based on the wire part program file.
