Via a catheter, ALZETR Osmotic Pumps can deliver substances into the venous or arterial circulation, into the brain, or into any organ lumen, or solid tissue. DURECT Corporation offers a range of specialized catheters, compatible with ALZET pumps, to enable targeted delivery to a variety of sites.

Catheter applications with ALZET Osmotic Pumps

Common Routes of Administration Requiring Use of a Catheter

  • Direct delivery of test agents pecisely into any target tissue or organ
  • Delay administration of test agents to allow for a surgical recovery period
  • Infuse for a short period using a longer duration pump
  • Create a time-patterned delivery of an agent

Note: No catheter is necessary when systemic delivery is desired. This is accomplished by subcutaneous or intraperitoneal implantation of an ALZET pump without a catheter.

  • Articular cavity
  • Blood vessels
  • Bone
  • Brain (solid tissue)
  • Brain (ventricles)
  • Ear
  • Eye
  • Muscle
  • Nerves
  • Spinal cord
  • Stomach
  • Tumors

Polyethylene (PE) and Vinyl Tubing

Medical grade PE and Vinyl tubing, the most common catheter types used in laboratory animal research, are available sterile, individually packaged, and ready to use.
