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.
Common Routes of Administration Requiring Use of a Catheter
- Articular cavity
- Blood vessels
- Bone
- Brain (solid tissue)
- Brain (ventricles)
- Ear
- Eye
- Muscle
- Nerves
- Spinal cord
- Stomach
- Tumors
