TITAN-PORT APH (extracorporeale apheresis) is a fully implantable port catheter system providing an access facility for performing extracorporeal apheresis. The set contains a titanium port chamber with a self-sealing silicone membrane and a single-lumen polyurethane catheter for connection to the port chamber and fixing to the outlet tube with a screw. Each system also includes a special puncture needle SFN 1835 B, an introducer set, a tunnelizer, a vein lifter, a rinsing needle, a port needle SFN 0930 G, user instructions and patient ID card.
The port chamber is made of hypoallergenic, biocompatible titanium. The material is non-magnetic. The chamber dimensions are: width 20.6 mm, height 16.7 mm, length 25.5 mm, weight ca. 15 g, priming volume 1.4 ml. The base plate has suture openings for securing the system to the fascia. Port chamber and catheter can be disconnected and are connected via a screw with the outlet tube.
The silicone membrane in the port (118 mm2 puncture area) can be punctured frequently with a suitable non-coring puncture needle. The membrane is highly resistant to pressure and holds the inserted needle reliably in place.
The single-lumen polyurethane catheter 10 F, with an outer diameter 3.35 mm, an inner diameter 2.0 mm, total length 70 cm, has at the distal end a special catheter tip (fishmouth tip) and if necessary the catheter can be shortened at the proximal end. After implantation, the distal tip reduces adsorption at the vessel wall, thereby also improving the flow rate. The catheter is radiopaque.
Only the special puncture needles for dialysis ports provided must be used for puncturing the membranes.
