Basic Information

• Recruitment Status: COMPLETED

Brief Summary

The objective of this study is to assess the performance and safety of the Optiflow Anastomotic Connector (Optiflow) when used to facilitate the creation of autogenous arteriovenous fistula (AVF) anastomoses.

Detailed Description

The investigation is designed as a multi-center, prospective, single-arm, clinical study of the Optiflow performance and safety in a maximum of 180 subjects which includes one (1) roll-in subjects per investigator (maximum of 36 roll-in subjects). Subjects will be followed at 14 days post-procedure, 42 days post-procedure, and 90 days post-procedures.

Results will be compared to a pre-established performance goal.

Up to fifteen (15) investigational sites will participate in the investigational study.

The primary performance endpoint is the overall maturation percentage rate at 90 days. Maturation is defined as an access site which achieves a diameter of greater or equal to 4 mm and blood flow greater or equal t0 500 mL/min as measured via duplex ultrasound.

The primary safety endpoint is a composite endpoint of serious adverse events known to be associated with arteriovenous fistula anastomosis surgical procedures through 90 days.

• Diagnosed with ESRD or chronic kidney disease requiring dialysis.
• Planned upper extremity autogenous arteriovenous fistula.
• Planned anastomosis is an end of vein to side of artery configuration.
• AVF target artery and vein inner diameters are greater or equal to 3.0 mm and less than or equal to 7.0 mm as determined by pre-operative ultrasound and confirmed intra-operatively.
• Patient is available and willing to return for follow-up visits during the duration of the study.

Exclusion Criteria

• Patient, or their legal representative, is willing and able to provide informed consent.

• Known bleeding diathesis or coagulation disorder.
• Documented or suspected central venous stenosis.
