Medical Grade Polyurethane
Concert Medical’s latest Interventional Guidewire development capability features the inclusion of a polymer jacket on the distal 30cm active end of a device. The jacket replaces the proximal stainless-steel coils and encapsulates the distal radiopaque 3cm Platinum Tip coil. There are a number of advantages to the polymer jacket guidewire approach.
- The jacketing process is possible on a variety of product ranges.
- The jacket is constructed using Medical grade Polyurethane.
- Radiopaque filler material can be included in the blend for X-ray visibility.
- A durometer of 85A is typical for this product.
- The distal tip is radiused for reduced trauma.
- Jacket is compatible with Concert Medical’s CoilCoat Hydrophilic Coating.
- Smooth Surface finish.
- Stacking and movement of coils is overcome.
- Reduced Surface area exposed to the blood.
- Soft Durometer material provides damping of the core material.
- Encapsulation avoids unravelling of the coiled wire.
- The Polymer is bonded onto the entire length of the tapered core ensuring no loss of Torque or Push.
Pressure Wire Tips
Complex Tips for Pressure Wires
Concert Medical develops and manufactures complex tips for pressure wires required to perform physiological measurements (FFR, dPR, Pd/Pa) to accurately measure blood pressure and flow through at a specific part of an artery. These measurements are important in assessing how to treat a patient.
Concert Medical employs its vast experience in Interventional Guidewire development to integrate the required technologies into the pressure wire tip elements without compromising the flexibility and trackability the product is still required to possess as an Interventional Guidewire.
The pressure guidewires measure the distal pressure in the coronary artery and a computer calculates ratios from the aortic pressure to define if the narrowing is altering the myocardium perfusion.
CenteRing Corewire Technology ensures the torque transmitted along a guidewire is distributed evenly around the circumference of the guidewire right to the tip. Therefore, offering true 1:1 torqueability. If the corewire is not centred within the guidewire coils, there is a high likelihood that the torque forces will be heightened on the side of the guidewire the corewire is closer to. Therefore, transmitting bias torque along the length of the guidewire. 1:1 torqueability is essential for a physician to have complete control of a guidewire’s movement during navigation of tortuous vessels.
Hydrophilic Coating Technology
Concert Medical’s proprietary CoilCoat Hydrophilic Coating Technology makes a guidewire very lubricious when hydrated.
The coating adds no additional stiffness to tip flexibility.
CoilCoat hydrophilic coating is applied to the entire coiled area of a guidewire.
Hybrid Corewire Technology
DuoCore Hybrid Corewire Technology is a hybrid of Stainless Steel and Chromium enriched Nitinol materials. The Stainless Steel proximal core wire offers optimized pushability for easier lesion access. The Chromium enriched Nitinol distal core wire provides optimal flexibility and precise steering.
The Stainless Steel shaping ribbon enables easy tip shaping and outstanding shape retention. Furthermore, the Nitinol distal core wire features improved durability. This combination empowers for multiple lesion access.
Gold Plating Technology
Eureka Gold Plating Technology offers unrivalled bond strength between the guidewire coils and the underlying corewire, while not creating patches of radiopacity to confuse the true tip (Pt coil) of the guidewire.
Bond strength between the coil and the corewire is essential to reduce the incidence of coil dislocation from the guidewire; often witnessed as one of the higher failure modes for guidewires during procedures.
