The NHancer Rx is a dual lumen Rapid Exchange single use device, consisting of a hub, a shaft, a distal tip at the Rx section and a proximal tip at the OTW section. The NHancer Rx has an over the wire (OTW) lumen that runs the length of the catheter and a rapid exchange (Rx) delivery lumen on the distal end. The NHancer Rx has two depth markings located at 95 cm and 105 cm from the distal tip to indicate that the distal tip of the catheter is at the level of the distal tip of the guiding catheter. As aid in positioning the NHancer Rx has a radiopaque marker, visible with fluoroscopy, identifying the distal end of the catheter and a second radiopaque marker identifies the distal end of the OTW lumen.
On the proximal shaft a torquer is placed. With the torquer placed on the proximal part of the shaft the device can be locked on to the guide wire that is in the device in such way that the guide wire and the NHancer Rx act as being one integral device. The strain relief at the hub is to prevent kinking of the shaft.
To ease catheter loading into the hemostasis device and the guiding catheter a removable stiffening stylet is placed in the OTW lumen at delivery.
- Two distal exit ports for optimal access of side branches
- Re-enforced shaft for optimal push
- Torquer for optimal maneuverability
The catheter is intended to support a guide wire during access of vasculature and allows for exchange of guide wires and provides a conduit for the delivery of diagnostic contrast agents.
A guide wire is used to bring interventional devices (balloon catheters; Stent delivery systems) to and into the occlusion. Procedures with a high level of complexity require enhanced guide wire performance which is not always possible to achieve with conventional devices.
