Physician’s Frequently Asked Questions

Q. What is the shaft diameter?

A. The PolypVac is available with two shaft diameters: 3.3mm and 4.0mm. The larger device has a faster rate of tissue resection, and the smaller device may be advantageous in restricted anatomy.

Q. Does the syringe need to be pressurized during the procedure?

A. It is not necessary to pressurize the syringe during the procedure. After priming, irrigant will be drawn automatically.

Q. Do I have to use the filter with the PolypVac? Can I collect multiple tissue samples with it? Can it be purchased separately?

A. The specially designed filter included with each PolypVac is available, but not required, for collection of tissue samples when using the PolypVac. Multiple tissue samples can be collected by opening the filter and removing the samples as needed during a procedure. The filter is not sold separately at this time and is not intended to be reused.

Q. Will the PolypVac work with the suction I have?

A. The PolypVac is designed to work with both wall suction and suction from portable and fixed-installation pumps.  Increased airflow from the suction source improves the resection speed.  As a result, some suction sources will provide better PolypVac performance than others. The minimum suction source specifications for supplying the 3.3mm PolypVac are 20 inHg and 28 lpm (liters per minute), and the minimum source specifications for supplying the 4.0mm PolypVac are 20 inHg and 48 lpm.

To ensure adequate suction air flow is available to all of our customers, we offer a pump that has excellent flow rate characteristics appropriate for both PolypVac sizes. Keep this pump in mind if you are unsure whether your system provides adequate air flow to power the device. More information on this pump is available here: Cliq AS-1001D Vacuum Pump.

Q. Can the PolypVac be used on tissues besides polyps?

A. The PolypVac is designed and tested specifically for use in removing nasal polyp tissue. It is not intended for use on other tissues.

Q. Is there a particular technique for using the PolypVac?

A. The PolypVac is designed to be intuitive when used by an experienced surgeon. The best resection results are achieved by using maximum suction, positioning tissue completely over the cutting window, and holding the trigger down fully.

Q. What if the PolypVac clogs?

A. In the clinical setting, clogging of the PolypVac has been extremely rare. However, in the unlikely event that the PolypVac does clog, a stylet is included in the packaging and may be inserted through the cutting window to clear the clog.

Q. Is the tip design just like that of a traditional microdebrider?

A. While they perform similar functions, the blade of the PolypVac is reciprocating (back-and-forth) rather than oscillating (side-to-side) as compared to common electrically powered microdebriders.

Q. Is the speed of the PolypVac variable or adjustable?

A. For convenience, the speed of the PolypVac is not variable or adjustable. The trigger is actuated in an on-off fashion providing a single speed that is designed for polyp tissue resection. Depress the trigger fully during use.

Q. Can the PolypVac be used in the operating room?

A. While the PolypVac has been specifically designed to be a convenient tool for removal of polyps in the office or clinic setting, there is no reason it cannot be used in the operating room as well.

Q. Does the PolypVac use batteries or have any special disposal requirements?

A. The PolypVac is powered solely by suction and does not have any electrical components or batteries.  It is constructed entirely of plastic and metal components.  It should be disposed of using standard biohazard disposal procedures.

Q. Is the PolypVac reusable?

A. No, the PolypVac is for single-use only and cannot be cleaned or decontaminated and will be functionally compromised in the period after initial use. Reuse represents a health and safety risk to patients.
