UNO Vascular Occluders

GET QUOTE!

These inflatable silicone cuffs are designed for the occlusion and constriction of blood vessels and soft organ without traction or displacement of the surrounding tissue. Occluders can be externalized or attached to any model Vascular Access Port for a totally subcutaneous system. The occluders are soft and flexible with a smooth outer finish and may be autoclaved or ETO gas sterilized. Heavy Duty (HD) occluders are designed for greater resistance to rupture. They feature a thicker cuff and diaphragm to withstand back pressures beyond the physiological norm.

Occluder plus VAP 

  • Reduced exit site infection
  • Reduced catheter mutilation
  • Totally closed subcutaneous system

 

 

Occluders applications

  • Reliable total or partial vascular occlusion
  • Reliable determination of zero-flow baseline blood flow measurements
  • Allow for constriction of soft organs/vessels such as; bile duct, urethra, intestines...

Occluders are available in the following sizes:

Cat. No. Lumen Diameter Cuff Width Cuff Thickness Product Information
OC1,5 1,5mm 3,5mm 1,5mm

The occluder cuff dimensions when deflated are usally the determining factor in the selection of the proper size device.

The actuating tube length is 90cm. Longer lengths are available on request. Lengths over 2 meters are not recommended.

Actuating tubing diameters:

OC1,5 - 10 including HD* series:ID 0,8mm x OD1,6mm

OC12 - 24 including HD* series: ID 1,0mm x 2,1mm

OC2 2mm 5mm 1,5mm
OC3 3mm 5mm 1,5mm
OC5 5mm 5mm 2,0mm
OC8 8mm 7mm 2,5mm
OC12 12mm 8mm 2,5mm
OC16 16mm 12mm 2,5mm
OC24 24mm 12mm 2,5mm
OC12HD* 12mm 9mm 3,0mm
OC16HD* 16mm 13mm 4,0mm
If you want to order an occluder with a Vascular Access Port, please mention both ordering codes. F.i. CP2AC-OC12.

Occluder operation:

  1. Apply the occluder cuff around the surgically exposed vessel and secure by tying sututres through the eyelets.
  2. Tunnel the occluder tubing to the VAP or external exit site.
  3. To occlude the vessel, water is injected into the VAP or external luer with a syringe, thereby inflating the diaphragm and occluding the vessel.
  4. To deflate the vessel, the water is withdrawn.

Response is very rapid and occlusion can be maintained for several hours, as long as the occluder is pressurized. For prolonged occlusion, the device should be filled with non-volatile inert liquids. Glycerin or a 50% Glucose solution is recommended for long term occlusion.

Occluders are constructed of soft biocompatible, silicone rubber.
