Precision Engineered for Coronary Intervention
Successful Percutaneous Transluminal Coronary Angioplasty (PTCA) relies fundamentally on precise guidewire performance. Vasmed comprehensive portfolio of 0.014″ PTCA guidewires is engineered to meet the diverse challenges encountered in modern interventional cardiology, from navigating tortuous vessels to crossing complex lesions, including Chronic Total Occlusions (CTOs). Each wire from Vasmed is designed with specific material compositions and construction techniques to optimize critical performance characteristics.
Our guidewire designs incorporate advanced materials and manufacturing processes to achieve superior control and reliability:
Key Performance Characteristics for selecting the optimal guidewire
Vasmed guidewires are provided with varying tip load to support various interventional requirements, the tip-load is defined as gram force required to cause buckling or significant deflection of the distal wire tip. It quantifies the tip’s stiffness and penetration capability (higher load) versus its softness and potential for atraumatic navigation (lower load).
-
Vasmed Floppy Wire
< 0.7gmf
-
Vasmed Regular Wire
Between 0.8 – 0.9gmf
-
Vasmed Support/Extra Support Wire
Between 0.8 – 1.1gmf
Vasmed corewires are designed with advanced annealing processes that improve the support, torque and pushability. Pushability defined as the efficiency of transmitting axial force applied at the proximal end to the distal tip, enabling advancement through resistance without energy loss or shaft buckling. Primarily determined by core material stiffness and shaft construction.
Vasmed guidewire trackability allows the distal section to follow the natural course of the vessel, including tortuous segments, without prolapsing or deviating. Influenced by distal flexibility, tip design, and shaft coatings. The varying designs of tapers for the guidewire allows for more support at the distal section to highly flexible distal section, which allows usage with highly torturous vessels.
Vasmed guidewire crossability provides the capacity of the guidewire tip and distal segment to successfully navigate through tight stenotic lesions or complex obstructions. A function of tip profile, lubricity, tip load, and pushability providing sufficient forward force.
Vasmed guidewires are provided with 3 designs to support crossability
-
Coil Reinforced tip
-
Support reinforced tip
-
Urethane coated tip
In addition, all our wires use Silicon – hydrophobic coated which allows for optimal cross ability.
Ease of steerability is a key aspect for Vasmed guidewires, the fidelity of transmitting rotational force from the proximal manipulator to the distal tip at 1:1 ratio is Critical for precise directional control and navigating vessel bifurcations or angles.
The ability of the formed tip shape to resist deformation during navigation and device passage, crucial for maintaining steering control and preventing vessel trauma. Our tips are made in such a way that it easily resist deformation at the same time allow for user reshape of the tip.
