The guidewire comprises an elongated flexible shaft which is tubular. A coil assembly comprises a first coil having a proximal portion with a peripheral size providing an unstressed fit within the distal portion of shaft. Tight recesses formed between consecutive turns of the coil by a solder filler hold adhesive between the coil and the tubular shaft.

[ I claim:] [1.] A guidewire comprising:an elongated flexible shaft having a proximal portion and a distal tubular portion;a coaxial assembly at the distal portion of the shaft, the coaxial coil assembly including a first coil having a proximal portion and a distal portion, the proximal portion of the first coil being inserted into the distal tubular portion of the shaft, a second coil having a proximal portion joined to the distal portion of the first coil and a distal portion terminating into a tip; andan adhesive bond for the proximal portion of the first coil in the distal tubular portion of the shaft, wherein the proximal portion of the first coil has a peripheral size providing a fit of the proximal portion of the first coil within the distal tubular portion of the shaft such that the adhesive bond is disposed at least in part within a gap defined between the first coil and the shaft.
