TITAN-PORT D (dialysis) is a fully implantable, titanium PORT system providing an access facility for per-forming veno-venous dialysis. The set contains two identical port chambers with a self-sealing silicone membrane and a double lumen polyurethane cathe-ter each case with one inlet and one outlet connec-tion to a Port chamber, and two srews for fixation of catheter to port outlets. Each system also includes two special puncture needles, introducer set, tunnel-izer, user instructions and patient ID documentation.

The port chamber consists of hypoallergenic, bio-compatible titanium. This material is non-magnetic. The chamber has the following dimensions: width 24 mm, length 36 mm, height 17.5 mm, weight 25g, internal volume 0.6ml, outlet pipe diameter 3.5 mm. The base has 2 suture openings for securing the system to the fascia. Port chamber and catheter can be disconnected and are interconected via a srew twist mechanism that is connected with a sleeve to the outlet pipe.

The silicone membrane in the port can be punctured up to 1000 times with a suitable noncoring puncture needle. The membrane possesses high pressure stability and holds the needle securely in position.



There are 2 different systems available – with double-lumen PUcatheter 14 F and single-lumen silicone catheter 12 F

The doublelumen polyurethane catheter 14 F has two openings at the distal end corresponding to the doublelumen construction, recognizable also by the markings on the connecting piece. The longer seg-ment is for afferent blood flow, the posterior opening with two additional lateral openings are for efferent blood flow (see illustration). The internal volume of the longer catheter portion is 2.3 ml, the shorter one is 2.2 ml. Mixture of the blood is minimized and insignificant for the blood washing effect by the mandatory separation of the openings and the natural direction of blood flow of venous blood to the central vessels. The efferent and afferent sections of the catheter are connected to the two implanted ports. These may be shortened as required.

The single-lumen silicone catheter 12 F, with an outer diameter 4.0 mm, an inner diameter 2.5 mm, total length 40 cm and internal volume 1,6 ml, has 6 lateral holes at the distal end a round tip and if necessary the catheter can be shortened at the proximal (unperforated) end. After implantation, the distal round tip prevents flotation of the catheter tip at the implantation site, e.g. due to suction or pulsation in the blood vessel and reduces adsorption at the vessel wall, thereby also improving the flow rate.

Only the special puncture needles for dialysis ports provided must be used for puncturing the membranes.

In order to achieve the blood flow rate needed for dialysis, appropriately large lumen needles are required e.g. DPK 1835 and DPK 2035. These are specially bevelled to prevent fragmentation of sili-cone particles and puncture defects of the mem-brane. Each system includes two appropriate can-nulae. These are available separately for further applications.

The patient ID documentation included is filled out fully by the physician who performed the implanta-tion, and is handed to the patient who should always carry this document with him.

These user instructions should also be available to nursing staff and physicians responsible for further care.

The contents of the set are stated on the label of the double sterile blister packaging.


Puncture of port chamber only with special port needles is mandatory!

  1. DPK 1835, dialysis port needle with special bevel at the tip
  2. DPK 2035, dialysis port needle with mandrin and needle free adapter for puncturing implantable port catheter systems of venous-venous hemodialysis and peritoneal dialysis with large diameter to ensure an adaquate flow rate for dialysis guaranteed no punch defects because of unique bevel with mandrin.
