ChronoFlex® 4.5Fr - 9Fr Catheter.
Nitinol self-expandable distal-end anchor for anastomosing the catheter to a target blood vessel.
Long-term vascular access.
Percutaneous deployment under ultrasound imaging guidance.
Percutaneous access for hemodialysis with 14G/16G needle or IV catheter
Flow rates up to 500 ml/min.
Removable or replaceable through a procedural sheath.
Overview
Components
Procedure
Deployment
1. An introducer sheath is deployed over a guidewire in the target blood vessel.
2. The Tandem™ catheter is pushed through the sheath with the self-expandable Tandem™ anchor compressed into the sheath.
3. When exiting the sheath, the distal struts of the self-expandable Tandem™ anchor expand into the target vessel.
4. The sheath and the Tandem™ catheter are pulled back together until the expanded distal struts are in apposition with the inner blood vessel wall.
5. The proximal basket of the self-expandable Tandem™ anchor expands outside the blood vessel wall when the sheath is peeled off.
6. After verifying patency of the anastomosis, the guidewire is removed.
7. Finally, the Tandem™ access port is implanted subcutaneously. The Tandem™ catheter is potentially tunneled and trimmed and then connected to the implanted Tandem™ access port.
Ultrasound imaging guidance
Usage
To connect the hemodialysis machine, the subcutaneous Tandem™ access ports can be percutaneously accessed using a short IV catheter or a regular hemodialysis needle.
During hemodialysis, blood flow through the Tandem™ device can be monitored by ultrasound color flow imaging.
