Catheter applications with ALZET Osmotic Pumps

  • 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.
