NCT02069860

Brief Summary

A Bone Anchored Port System (BAP) will be implanted in the mastoid bone behind the ear, connected with a double lumen central venous catheter inserted in the jugular vein, and will be used in conjunction with an adapter as a permanent vascular access for hemodialysis treatment.

Outcome Measures

Primary Outcomes (1)

  • Device survival probability after one year

    An event is the primary failure of BAP, defined by necessity to remove the device for any medical reason (e.g. infections at wound or mastoid, thrombosis, and severe patient discomfort).

    up to 12 months after Study start

Secondary Outcomes (1)

  • Performance - Implantation and primary healing process

    up to 18 months after Study start

Other Outcomes (3)

  • Performance - removal of catheter

    up to 18 months after Study start

  • Performance - Dialysis use

    up to 18 months after Study start

  • Design Validation

    up to 18 months after Study start

Study Arms (1)

Access for heamodialysis treatment

EXPERIMENTAL

The Bone Anchored Port System (BAP) will be implanted in the mastoid bone behind the ear, connected with a double lumen central venous catheter inserted in the jugular vein, and will be used in conjunction with an adapter as a permanent vascular access for hemodialysis treatment

Device: Bone Anchored Port System (BAP)

Interventions

The port body will be implanted onto the petrous bone and a sealing cap, a twofold valve system and a catheter are connected to the port body. The catheter is tunneled under the skin, enters the internal jugular vein and ends in the right atrium of the heart. The novelty of the access lies in its location (retro auricular on petrous bone) and its bone fixation.

Access for heamodialysis treatment

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Indication for a permanent haemodialysis access
  • Impossibility to construct or revise an AC-Fistula
  • Age \> 18 years.
  • Written, informed consent.
  • Availability of vascular imaging of the jugular vein at the implantation site with no contraindication for a jugular vein catheter

You may not qualify if:

  • Clinical contraindications for the implantation of a BAP including:
  • known intolerance to any of the BAP materials
  • ongoing infections e.g.
  • mastoiditis / otitis media
  • skin infection in the area of presumed implantation-site
  • generalized acute and chronic infections
  • severe skin lesions (e.g. dermatitis, psoriasis) in the area of the presumed implantation site
  • previous surgery at the petrous bone
  • deafness
  • known significant bleeding disorder
  • known thrombophilia
  • Life expectancy less than 1 year from the time of enrolment in the study.
  • Expected transplantation within the intended study duration (i.e. known living donor).
  • Pregnancy or breast feeding.
  • Women of childbearing potential without appropriate contraceptive method.
  • +6 more criteria
