摘要

A guidewire for use in guiding the insertion of catheters bears a plurality ofunique identifiers. These unique identifiers are used to choose the appropriatelength of catheter to be inserted into the patient. Many of the steps of markingand measuring a guidewire and calculations utilizing the measurements are eliminatedthrough use of this catheter bearing unique identifiers. In place of the detailedand error prone set of marking, measuring and calculating steps, a set of uniqueidentifiers are printed or otherwise directly and immovable associated withthe guidewire. A practitioner determines the stock length of catheter neededin a procedure merely by noting the placement of one unique identifier relativeto a standard landmark.
