Hemodialysis Access Failure (Disorder) Clinical Trial
Official title:
Bone Anchored Port - a Novel Vascular Access for Hemodialysis Treatment
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.
STUDY OBJECTIVE The objective of the clinical investigation is to demonstrate feasibility regarding safety, efficiency and clinical performance of the BAP as a permanent access for chronic haemodialysis therapy in patients with renal failure to reach the certificate European (CE) mark and conduct a post market follow-up study. PRIMARY ENDPOINT 1) Device survival probability after one year (product - limit estimator of Kaplan-Meier Analysis). 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) SECONDARY ENDPOINTS 1. Performance - Implantation and primary healing process - Failure to implant a device due to procedural complications or unforeseen anatomical reasons, except for intra-operatively detected exclusion criteria - Successful attempt on the site contralateral to the planned side - Duration of the implantation procedure measured from incision to final suture - Duration of hospitalization before implantation / after implantation - Time from implantation to first use for haemodialysis - Rate of patients with complications stratified by - Dura mater exposed / injured - Blood sinus injured - Injury of facial nerve - Carotid artery puncture - Central vein perforation - Bleeding, defined as requirement for blood products - Pneumothorax - Hematothorax - Initial healing and stabilization of BAP, Infections at implantation site - Septicaemias with no other source of infection than surgical-procedures impairment for mechanical reasons 2. Performance - removal of catheter - Failure to provide a blood flow ≥200ml/min for more than 2 consecutive weeks - Catheter related and untreatable infection - Surgical or interventional (Seldinger technique) procedure - Persistent recirculation higher than 15% 3. Performance - Dialysis use - Average blood flow rate - Average venous pressure - Average arterial pressure - Recirculation - Volume-corrected clearance (Kt/V) - Access thrombosis reversible by non-surgical means - Infections of any kind - in anatomical structures around implant - remote infections possibly related to the BAP - bacteriemia/septicemia 4. Design Validation - Questionnaire for the implantation surgeon - Questionnaire for the dialysis staff - Questionnaire for patients - Quality of Life (QoL) Questionnaire (EQ-5D) - Questionnaire for change / removal of catheter ;
