An apparatus having a pump reservoir and one or more microcatheters, for use in delivering and/or recovering fluid to and/or from a tissue site or for performing tissue engineering outside of the body. The apparatus can be used in a method to perform site specific microtherapy, including for the treatment of avascular necrosis, compartment syndrome, cerebral edema, and to improve skin flap survival in the course of reconstructive surgery.

Microcatheter and method for site specific therapy

A system and related methods and components for treating tissue swelling, and particularly swelling associated with cerebral edema, compartment syndrome, and congestive heart failure, by the use of water removal therapy, in order to remove only water from biological fluids. Included also is a system for such use that incorporates one or more monitors, optionally in addition to the use of water removal therapy. By removing only water, all other biologic agents, including essentially all solutes and formed blood elements (such as cells) are increased in concentration in the remaining bodily fluid(s). WRT can be applied to several clinical conditions in which there is an excess of water, and is ideally used in an extracorporeal fashion, in combination with other functions and related components as well, including ultrafiltration.

System for treating tissue swelling

A system, including catheter apparatus, and related method for performing site specific therapy. The catheter apparatus can include one or more semipermeable microcatheters for use in performing site specific microdialysis. The system and method are particularly suited for use in addressing cerebral edema by affecting the osmolar relationship between fluids making up the brain tissue. Also disclosed is an apparatus having a delivery/recovery mechanism in the form of a pump reservoir and one or more catheters in the form of semipermeable microcatheters, for use in delivering and/or recovering fluid to and/or from a tissue site or for performing tissue engineering outside of the body. The apparatus can be used in a method to perform site specific microtherapy, including for the treatment of avascular necrosis, compartment syndrome, cerebral edema, and to improve skin flap survival in the course of reconstructive surgery.

System and method for site specific therapy

A system, including catheter apparatus, and related method for performing site specific therapy. The catheter apparatus can include one or more semipermeable microcatheters (preferably in the form of hollow fibers) for use in performing site specific microdialysis. The system and method are particularly suited for use in addressing cerebral edema by affecting the osmolar relationship between fluids making up the brain tissue. Also disclosed is an apparatus having a delivery/recovery mechanism in the form of a pump reservoir and one or more catheters in the form of semipermeable microcatheters, for use in delivering and/or recovering fluid to and/or from a tissue site or for performing tissue engineering outside of the body. The apparatus can be used in a method to perform site specific microtherapy, including for the treatment of compartment syndrome or cerebral edema.
