Urology Catheters
Urodynamic Mikro-Tip® Pressure Transducer Catheters
Millar Instruments manufactures a complete line of solid-state pressure transducer catheters for use in urodynamic testing procedures. Millar catheters are used in a variety of studies such as cystometry (CMG), urethral/bladder pressure measurements, urethral pressure profiles (UPP), pressure/uroflowmetry and gynecological urodynamics. Millar Mikro-Tip®catheters are compatible with virtually all urodynamic systems on the market today.
Millar urodynamic catheters are now exclusively distributed domestically through Life-Tech, Inc. Call Life-Tech Customer Service Department at 281.491.6600 or 800.231.9841 or click here to visit their website.
Millar Instruments will handle all warranty and service items on urology catheters. Please contact Millar's Repair and Evaluation department at 832.667.7148.
Advantages of Mikro-Tip Urodynamic Catheters
Millar Mikro-Tip solid-state catheters offer many advantages over traditional fluid-filled catheters. These advantages are listed in the table below.
| Mikro-Tip Catheter | Fluid-filled Catheter | Mikro-Tip Advantage | |
|---|---|---|---|
| Flushing | Not required. | Flushing to remove air bubbles is required and is time consuming. | Saves time and money. |
| Zeroing and Calibration | At any level prior to study. | Requires precise positioning. | Saves time and money. |
| Catheter Whip and Impact Artifacts | Produces minimum artifact due to movement. | Inclined to catheter whip and impact artifacts. | Precise and accurate readings. |
| Frequency Response | Solid-state; no air bubbles to impact readings. | Frequency may deteriorate due to the introduction of air bubbles into the catheter, stopcocks, or tubing during catheterization. | Superior linearity,stability, and frequency response mean accurate measurement with fast pressure variations. |
| Patient Movement | Does not affect readings. | Must be minimized. | Enhanced patient comfort. |
| Design | One piece. | Multiple pieces. | Saves set-up time. |
Ambulatory Urodynamics
Traditionally, most cystometric and related urodynamic studies were conducted in the laboratory for short periods of time and under non-physiologic environments. Today, urodynamic system manufacturers offer ambulatory monitoring systems to monitor the patient in different positions (supine, sitting, and walking), during sleep, and while voiding. Millar Mikro-Tip pressure catheters are ideally suited to ambulatory urodynamic studies.
Millar offers several models of catheters for urodynamic studies. Models with filling lumens may be used for slow, medium, or fast filling as defined by the International Continence Society. The SUPC-780S has a filling lumen and two pressure sensors, one for the bladder (intravesical) and the other for reading urethral (intraurethral) pressures. The SUPC-380S is used for abdominal pressure (intrarectal/intravaginal).
All Millar urodynamic Mikro-Tip catheters are latex free.
