• Device Name: DIB INFUSOR
• Applicant: Novacon Corp.
• Product Code: MEB · General Hospital
• Decision Date: Aug 5, 1996
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 880.5725
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The intended use of the DIB Infusor is similar to that of other legally marketed elastomeric infusion pumps.

Device Story

DIB Infusor; elastomeric infusion pump; utilizes medical grade silicone shaft and silicone balloon; provides continuous medication delivery; used in clinical settings for pain management and IV infusions; operated by healthcare professionals; provides controlled flow via balloon pressure; benefits patients through consistent, portable drug delivery.

Clinical Evidence

Evidence includes in-vitro flow studies (University of Utah) and clinical literature documenting use for obstetrical analgesia, post-operative pain, chronic pain, and cervical epidural anesthesia. Studies include continuous epidural block, postoperative pain relief management, and treatment of Ramsey Hunt Syndrome.

Technological Characteristics

Materials: medical grade silicone shaft and balloon. Sensing/Actuation: elastomeric balloon pressure (normal operating pressure ~70 mmHg; tested to 110±5 mmHg). Form factor: disposable infusion balloon catheter. Standards: AAMI Draft Infusion Device Standard. Manufacturing: Class 10,000 clean room, GMP compliant.

Indications for Use

Indicated for patients requiring continuous infusion of medications, including obstetrical analgesia, post-operative pain management, chronic pain management, and intravenous infusions.

Regulatory Classification

Identification

An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.

## SUMMARY of SAFETY and EFFECTIVENESS for the DIB INFUSOR

### I. Standards and Intended Use

The DIB Infusors utilize all biocompatible materials, including a medical grade silicone shaft and silicone balloon. The DIB Infusor will conform to the AMMI Draft Infusion Device Standard. The intended use of the DIB Infusor is similar to that of other legally marketed elastomeric infusion pumps.

### II. Manufacturing and Testing Procedures

All manufacturing operations are performed in a class 10,000 clean room in accordance with GMP regulations. The silicone balloons are 100% tested to an internal pressure of 110±5 mmhg. Normal clinical operating pressure has been measured at approximately 70 mmhg. Full traceability of production lots will be maintained.

### III. Prior In-Vitro Tests and Clinical Experience
