Vascular Occluder Test Procedures

To insure accurate results, read these procedures carefully before placing this device into service.

Operational Principal
The occluder cuff is wrapped around the exposed vessel and secured in place using suture material passed through the eyelets. Air or liquid is then injected into the actuating tube by syringe inflating the diaphragm and compressing the vessel into occlusion.
Materials Required for Operation
For sizes VO-1.5N through VO-10, use a 20 gage blunted needle and a 10 cc syringe
For sizes VO-12 through VO-24 use a 16 gage blunted needle and a 20 cc syringe

Caution: We Do Not recommend implanting occluders without first testing them. See Test Procedure below
Caution: Do Not exert excessive pressure in the diaphragm as bursting may result. Use only enough pressure to achieve the desired degree of occlusion.
Caution: Do Not inflate unsutured occluders as damage or bursting may result.

Important: Testing Procedure Prior to Implantation
Secure the cuff ends together by tying suture material through the eyelets of the occluder before inflating.
Insert the proper size blunted syringe needle into the Occluder's actuating tube.
Inject just enough air or liquid into the tubing to inflate the Occluder's cuff to full occlusion.
CAUTION: DO NOT OVERINFLATE THE DIAPHRAGM AS BURSTING MAY RESULT
Hold pressure for 30 seconds while observing for possible leaks.
Repeat the procedure 4 to 5 times to relax the diaphragm, particularly if the occluder has not been used recently.

Calibration of the Occluder:
Carefully observe and note the air pressure or liquid volume required for varying degrees of occlusion. The same degree of occlusion may be expected after implantation.
FOR GREATER ACCURACY: calibrate this device in conjunction with a pressure gage, flow meter, or a simulated flow system.

Sterilization:
This device should be thoroughly cleaned immediately following each use to remove all organic residues.
This device is designed to be sterilized by Autoclave or by appropriate cold sterilization methods.

Repair of damaged occluders:
Some repairs may be possible depending on the severity of the damage. Contact us for further information and repair services we offer.
