Guidewire
Guidewire
Guidewire (pronounced: gahyd-wahyr) is a medical device used to guide the placement of a larger device, such as a catheter, in a patient's body.
Etymology
The term "guidewire" is derived from the English words "guide" and "wire". The term accurately describes the function of the device, which is to guide the placement of other medical devices within the body.
Usage
A guidewire is typically used in minimally invasive procedures, such as angioplasty or stent placement. The guidewire is inserted into the body first, and then the larger device is threaded over the guidewire and into the correct position. The guidewire is then removed, leaving the larger device in place.
