What is PTCA?
The Demax PTCA Guidewire is a specialized medical device used during percutaneous transluminal coronary angioplasty (PTCA) procedures. It is designed to facilitate the precise navigation of catheters and balloons within coronary arteries to treat narrowed or blocked segments and restore blood flow to the heart muscle.
- Balloon Angioplasty: Facilitates the precise navigation and placement of balloons within coronary arteries to dilate narrowed or blocked segments and restore blood flow to the heart muscle.
- Stent Placement: Aids in the accurate positioning of stents within coronary arteries to support the vessel and prevent restenosis following angioplasty.
- Atherectomy Procedures: Assists in the navigation of atherectomy devices for the removal of atherosclerotic plaque from coronary arteries.
- Thrombectomy Procedures: Facilitates the navigation of thrombectomy devices for the removal of blood clots from coronary arteries in acute coronary syndromes.
- Intravascular Imaging: Supports the precise positioning of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) catheters for intravascular imaging of coronary arteries.

Hydrophilic Guidewire
The composition of Hydrophilic Coated Guidewires typically consists of a core material, such as stainless steel or nitinol, surrounded by a hydrophilic polymer coating. Stainless steel provides the necessary rigidity and structural integrity to the guidewire, enabling it to withstand the forces encountered during navigation through the body. On the other hand, nitinol, a shape-memory alloy, offers flexibility and elasticity, allowing the guidewire to adapt to the contours of anatomical structures without sacrificing durability.
The hydrophilic coating, usually composed of PTFE or a similar material, serves as a lubricious layer that reduces friction and enhances the guidewire’s ability to glide smoothly through the vasculature or other bodily passages. This coating undergoes a specialized manufacturing process to ensure uniformity and durability, enabling the guidewire to maintain its hydrophilic properties throughout the duration of the procedure.
