Puncture Guidewire
Puncture Guidewire is composed of a stainless steel core wire and a stainless steel winding wire. The core wire provides stiffness and support for navigating through anatomical pathways, while the winding wire enhances flexibility and maneuverability. This composition ensures the guide wire’s durability and reliability during minimally invasive procedures, allowing healthcare professionals to navigate with precision and achieve successful outcomes for their patients.
- Length: Guidewires are available in various lengths to accommodate different procedural requirements, typically ranging from 450mm to 800mm.
- Diameter: The diameter of guidewires varies depending on the intended application, with options ranging from 0.018 inches to 0.038 inches.
- Flexibility: Guidewires come in different levels of flexibility, allowing healthcare professionals to choose the appropriate stiffness for navigating through different anatomical structures.
- Tip Configuration: Guidewires may feature different tip configurations, such as J-shaped, straight, or angled tips, to facilitate smooth advancement and minimize tissue trauma.
- Radiopacity: Some guidewires are designed with radiopaque markers near the tip to enhance visibility under fluoroscopy or X-ray imaging during placement.
- Vascular Access: In procedures such as central venous catheterization or arterial catheterization, the guide wire helps navigate through blood vessels to access the desired site for diagnostic or therapeutic purposes.
- Biopsy: During image-guided biopsies, the guidewire aids in positioning biopsy needles accurately within target tissues, ensuring precise sampling and diagnosis.
- Drainage Procedures: In interventions such as percutaneous drainage of abscesses or fluid collections, the guide wire assists in navigating through tissues to reach the desired location for drainage catheter placement.

Core wire Grinding
The core wire itself is typically made from high-grade stainless steel for strength and corrosion resistance, or Nitinol, a shape-memory alloy offering superelasticity crucial for flexible and kink-resistant guidewires and stents. Depending on the specific device needs, other specialty alloys like platinum, tantalum, and cobalt-chromium might be used for their unique properties. Additionally, the grinding process can be tailored to achieve specific surface finishes and the core wire might receive further coatings to enhance its properties and functionality within the final medical device.
