CODMAN® 3000 Constant Flow Pump Patient Support
What is the CODMAN® 3000 Constant Flow Pump?
The CODMAN® 3000 Constant Flow Pump is a small drug delivery system which is completely implanted beneath the skin. Depending upon the model selected by your doctor, the pump is about two to three inches in diameter, 3/4 to one inch thick, weighing four to six ounces, and approximately the size of a hockey puck. The CODMAN® 3000 Constant Flow Pump has been designed to hold approximately one ounce of medication.
The titanium pump is circular in shape with a small, raised area in the center called a septum. This septum is where the health care provider uses a special needle to fill the pump’s storage reservoir with pain medication via a needle stick through the skin. The medication flows from the drug chamber into the selected body site at a constant rate through a small flexible tube called a catheter.
How does the CODMAN® 3000 Constant Flow Pump work?
The CODMAN® 3000 Constant Flow Pump is powered by a special process using two chambers to enable pain medication to flow at a constant rate without the use of a battery. Since no batteries are used, the CODMAN® 3000 Constant Flow Pump is warranted for life and will not require replacement due to battery depletion.
The inside of the CODMAN® 3000 Constant Flow Pump is divided in to an inner chamber and an outer chamber by accordion-like bellows. The inner chamber, also known as the drug chamber, contains the pain medication to be delivered. The outer chamber contains a propellant that is permanently sealed inside. The temperature of your body warms the propellant, which in turn causes constant pressure on the drug chamber and bellows. This pressure causes the medication to flow out of the drug chamber, through a filter and a flow restrictor, and then slowly out of the catheter. The flow restrictor ensures that the medication flows at the optimal, predetermined rate that your doctor has chosen. Each time the pump is refilled, the propellant energy is recycled for another infusion period.
Refilling the pump with medication expands the bellows and starts the pump on the next cycle of drug infusion. The pump may be refilled as many times as necessary for your therapy.
How is the CODMAN® 3000 Constant Flow Pump implanted?
Implantation of the CODMAN 3000 Pump is done in the operating room under local or general anesthesia. The surgery normally takes between one and three hours. Your surgeon will place the CODMAN 3000 Pump under your skin in your lower abdomen.
On the day of your implant, you will be positioned on the operating room table lying on your side with the pump placement area facing up. Your surgeon will implant the pump in your abdomen and then extend a catheter that will go from the pump to the location that medication will be delivered. Once the catheter position is secured, your surgeon will place a bandage over incision sites where the catheter was inserted and over the incision site where your pump is located.
Although the pump is filled and begins to work immediately during surgery, some adjustments may be necessary over the first several weeks after it is implanted Your length of stay in the hospital depends on several factors but the most common hospital stay is 24 hours or less.
It is common to experience some soreness at the incision sites for the first few days after surgery. After the incisions heal, no special care of the sites will be required and you will be able to shower and bath as usual.
Prior to your discharge, your doctor or health care team member will provide you with important information regarding your new CODMAN® 3000 Constant Flow Pump and instructions for the care the incisions. You will also receive a Codman Patient Medical Alert Card for identification. You should carry this card with you at all times.
How is my pump refilled?
Depending upon the flow rate of your individual pump, your doctor or nurse will refill the pump every four to eight weeks. When you go into the office for a scheduled visit, a member of the healthcare team will begin by cleaning your skin at the pump site.
A special needle with a syringe attached will then be inserted into the septum in the top of the pump. You will feel a mild “pinprick” sensation as the needle passes through the skin into the septum. This will allow all the medication remaining in the pump to flow out of the pump into the syringe. Next, a syringe containing the refill pain medication will be attached to the needle already in place, and the pump will be refilled. Refilling the pump with medication expands the bellows and starts the pump on the next cycle of drug infusion. The refill procedure takes 10-15 minutes and you should not feel pain other than the “pinprick” sensation.
How is a bolus injection performed?
In addition to the continuous infusion capabilities of the CODMAN® 3000 Constant Flow Pump, medication can be delivered to the tip of the catheter via the bolus pathway injection.
Do I have to limit my activities?
Once you have recovered from surgery, you will be able to continue most of the activities you enjoyed before the surgery. Your doctor or nurse will be able to give you guidelines, however there are a few specific things to remember:
- Avoid rough physical activity like contact sports to protect the pump site.
- Avoid deep sea and scuba diving. Increased pressures will affect the flow rate of the pump. Snorkeling and swimming will have no effect on the flow rate, so you may continue these activities.
- Do not place heating pads and/or water bottles directly over the pump implant site. Direct contact of the heating pad or water bottle over the pump pocket site will increase the local temperature, thereby causing the pump to flow slightly faster.
- Minimize your exposure to saunas and hot tubs for extended periods of time. Prolonged exposure will elevate your body temperature and may cause your pump to flow faster.
- Let your doctor know if you plan to travel by air or move to another location as your medication may need to be adjusted.
- Call your doctor or nurse if you have a fever, if there is any change at your pump site, or if your pain management is ineffective.
Will my insurance company pay for the CODMAN® 3000 Constant Flow Pump?
Insurance coverage differs from company to company. However, most insurance companies will provide financial support for the placement and care of the pump. To be sure, check with your insurance carrier to determine the extent of your coverage
What happens if I miss a scheduled appointment?
It is very important for you to keep your refill appointments so that the pump does not run dry. If you cannot keep an appointment, be sure to call your doctor or nurse for alternate arrangements.
Can I travel with my CODMAN® 3000 Constant Flow Pump?
Your CODMAN® 3000 Constant Flow Pump should not stop you from enjoying travel. It is your responsibility to let your doctor know before you travel if you plan to be away for longer than your scheduled refill period. Your doctor can refer you to a physician in another area while you are on vacation. Although unlikely, it is possible that the airport security system will detect your pump. If this does occur, simply present your Codman Patient Identification Card to the security personnel.
Can I safely have an Magnetic Resonance Imaging (MRI) procedure with the pump?
The CODMAN® 3000 Constant Flow pump is 1.5T and 3T MRI conditional. For a complete listing of our MRI Conditions to be provided to your MRI Health Care Professional (HCP) please visit the Codman 3000 MRI Conditions.
Will I need to have the CODMAN® 3000 Constant Flow Pump forever?
The majority of patients do continue their pump therapy indefinitely. If the need for the medication the pump is delivering is eliminated, the pump can be surgically removed
