The MPS Acacia MedFlo Elastomeric Pump is indicated for continuous and/or intermittent infusion of medications for general infusion use, including antibiotic delivery, chemotherapy, and pain management. Routes of administration include intravenous, intra-arterial, subcutaneous, intramuscular, and epidural. The keep vein open (KVO) version provides a sufficient flow rate to maintain a patient IV line open (i.e. keep vein open). The MedFlo Elastomeric pump may also include an optional Y-site at the distal end of the administration set to allow piggyback infusions, and an optional bolus mechanism intended for patient controlled infusion.

The MPS Acacia MedFlo Elastomeric Pump is also indicated for continuous and/or intermittent delivery of medication, such as local anesthetics or narcotics, to surgical wound sites and/or close proximity to nerves for preoperative, perioperative, and postoperative regional anesthesia and pain management. Routes of administration include intraoperative, perineural, and percutaneous.

The MPS Acacia MedFlo Elastomeric Pump is also indicated to significantly decrease narcotic use and pain when used to deliver local anesthetics to surgical wound sites or close proximity to nerves when compared with narcotic only pain management.

The MPS Acacia MedFlo Elastomeric Pump is disposable and single use only.

Indications for use as stated in the FDA summary.
