Abstract: A method and apparatus are provided for releasably storing the additional exchange length of a medical guidewire within a housing, in a compacted configuration until it is needed by the physician to perform a catheter exchange. This guidewire has a distal portion which is similar to a traditional guidewire in length and construction and is used throughout the catheterization procedure much like a conventional guidewire. A proximal portion of the guidewire provides added length to effect a catheter exchange in the manner of a conventional exchange wire but may be tightly compacted and stored out of the way within a storage receptacle until the moment that the added length is needed for an exchange. The storage receptacle enables the physician to utilize the distal portion of the guidewire wire much like a conventional guidewire, then release the proximal portion quickly to effect a catheter exchange.
