A catheter device comprising: a micro-fabricated elongated outer member having an outer surface and an interior surface forming a lumen extending from a proximal end to a distal end and a plurality of fenestrations made through said outer surface and said interior surface into at least a portion of said lumen; and an outer elastomer laminate layer in contact with at least a portion of said outer surface and filling said plurality of fenestrations, and embodiments thereof.

Micro-fabricated Catheter Devices Formed Having Elastomeric Fill Compositions

A guidewire device comprising an elongated outer member having an outer surface and an interior surface forming a lumen extending from a proximal end to a distal end, wherein an outer diameter of said distal end is larger than an outer diameter of said proximal end; and an inner member disposed within a portion of said lumen, and embodiments thereof.

Micro-fabricated Guidewire Devices Having Varying Diameters

An outer coil and an inner coil are joined in parallel with a distal end portion of a core of a guide wire. A winding direction of a strand of the outer coil is the same as that of a strand of the inner coil. Diameters of the outer and inner coils increase or decrease when rotation of the core is transmitted and thereby rotation transmission capability is improved. An outer space wound portion and an inner space wound portion are formed in corresponding positions in the outer coil and the inner coil, respectively, in a core direction. Even if the guide wire has a double-coil structure, the outer and inner space wound portions improve flexibility of the guide wire. A coil pitch of the outer space wound portion differs from a coil pitch of the inner space wound portion. Thereby, engagement of the strands is prevented.

Medical guide wire

A guidewire device comprising: a micro-fabricated elongated outer member having an outer surface and an interior surface forming a lumen extending from a proximal end to a distal end; an outer elastomer laminate layer in contact with at least a portion of said outer surface; and an inner member disposed within a substantial portion of said lumen, and embodiments thereof.

Micro-fabricated Guidewire Devices Formed Having Elastomeric Compositions

Micro-cutting machines for forming cuts in catheters, guidewires, and similar products, are disclosed, including a micro-cutting machine that can directly control the dimensions of the resultant beams being cut into products, and that can capture images of each cut for feedback control and accuracy verification.

Micro-cutting machine for forming cuts in products

Medical devices and methods for manufacturing medical devices. An example manufacturing method includes providing a metallic tubular member having a inner surface with a metal oxide layer disposed thereon, mechanically scoring and/or removing a portion of the metal oxide layer to create a bonding zone along the inner surface, and soldering an additional metallic structural element to the bonding zone.
