Product Description

The SEQURE® microcatheters are single use microcatheters primarily comprised of a luer lock hub, a strain relief cover and tube, central shaft,
and distal tip with a radiopaque marker for visualization. The SEQURE® microcatheters are used for infusion of therapeutic agents, embolic
material and fluid such as contrast media.
The catheters consist of a metal braid reinforced shaft with external multi-polymer tubing. The braid provides trackability, pushability and torque
transmission to the microcatheter as well as visibility under fluoroscopy. The inner lumen is made of PTFE (polytetrafluoroethylene), which
allows for the smooth passage of fluids, embolic agents and devices such as guide wires. The distal section of the shaft is coated in a hydrophilic
polymer layer, which ensures high lubricity when wet with saline or blood.
At the proximal end there is a luer-compatible hub connected to a strain relief cover which helps prevent kinking due to the weight of the hub.
The SEQURE®'s distal end has two radiopaque markers that contribute to the fluoroscopic visualization of the distal tip of the microcatheter. The
two radiopaque bands mark the boundaries of the SEQURE® side holes/slits.
The SEQURE® microcatheters are single lumen devices and are available in several different diameters and lengths..
