Vascular Access Ports
Ports are entirely implanted catheter devices which do not exit through the animal’s skin. There is little concern about the animal disturbing the port thereby obviating the need for a jacket or other protective apparatus. Because there is no chronic exit site wound, infection risks associated with ports are considerably lower than with external catheters. The use of ports has provided many new research opportunities, and it represents a refined technique which has reduced animal use and minimized stress.
Catheter Biomaterials
Silicone
rubber continues to be the most common material; however,
polyurethanes have proven to be more hemocompatible than
silicone. Furthermore the CBAS® heparin coated polyurethane
has proven to be the most thromboresistant material of all
available technologies. This catalog offers a full range of silicone,
polyurethane, and CBAS®-coated polyurethane catheters in sizes for all species
Round Tips
The round distal tip is less traumatic to the
intimal lining of blood vessels. Square cut or bevel cut catheters
have sharp edges which irritate the blood vessel’s intimal lining thus
hastening the host’s thrombogenic response. Round tips are available
on polyurethane and CBAS®-coated polyurethane catheters.
