Guidewire

Guidewire is a medical device used to guide catheters or other medical instruments through the body during a procedure. It is a thin, flexible wire that is inserted into the body and then used to guide other instruments to the correct location.

Uses

Guidewires are used in a variety of medical procedures, including cardiac catheterization, angioplasty, and stent placement. They are also used in endoscopy procedures and in the placement of central venous catheters.

Types

There are several types of guidewires, including:

• Hydrophilic guidewires: These guidewires have a coating that becomes slippery when wet, making them easier to maneuver through the body.

• Hydrophobic guidewires: These guidewires do not have a coating and are not as slippery as hydrophilic guidewires.

• Steerable guidewires: These guidewires can be controlled by the doctor to move in specific directions.

Risks

While guidewires are generally safe, there are some risks associated with their use. These include:

• Infection: As with any procedure that involves inserting an instrument into the body, there is a risk of infection.

• Damage to blood vessels: If the guidewire is not properly maneuvered, it can cause damage to blood vessels.

• Misplacement: If the guidewire is not correctly placed, it can lead to complications.
