GPV & SLA Ports - Our Tried & Tested Polysulfone Models
The model GPV was introduced to the animal research community in 1981 and was the first vascular access port available for use in preclinical research. It soon became apparent that a smaller access port was needed by researchers and so the SLA was introduced in 1986.
Model GPV – introduced in 1981
Use in large animal species – swine, sheep, large dogs.

Model SLA – a favorite since 1986
Use in smaller animal species – cats, rabbits, small dogs.

Vascular Access Port Advantages:
– no external component
– promotes group housing and socialization
– no exit wound
– minimizes infection opportunity
– low maintenance
– subcutaneous location
– ideal for long-term access procedures
– limits repeated venipuncture & preserves peripheral vasculature
– provides access to a variety of internal environments
– can be attached to arterial, venous, gastric, spinal, portal catheters
– can be attached to a vascular occluder
– for studies involving flow restriction
