Cook Medical G32724 - DEVICE, NTRAP, ENTRPMNT, EXTRCTN, NTP-028145, EACH
NTrap Stone Entrapment and Extraction Device
The NTrap Stone Entrapment and Extraction Device is used to remove calculi and other foreign bodies in the urinary tract, and to minimize stone migration during laser, ultrasonic, electrohydraulic, or pneumatic lithotripsy.
Set contains (set components may vary)
- Stone Extractor
- Unidex Handle
| Order Number | Reference Part Number | Fr | Length (cm) | Basket Configuration |
| G32724 | NTP-028145 | 2.8 | 145 | 7 mm umbrella design |
Features and Benefits
- Basket design: The intricately woven, multiwire basket prevents the migration of fragments that are as small as 1.5 mm in diameter.
- Nitinol construction: The resilient shape-memory characteristics of the nitinol wire allow the basket to retain its shape after deployment.
- Flexible sheath: The 145 cm long sheath allows efficient scope exchange.
- Removable handle: While the basket is deployed, the handle can be detached so that the scope can be withdrawn. Removing the scope from the working channel of the access sheath allows increased irrigation.
Intended Use
Used as an endoscopic entrapment and extraction device for calculi and other foreign bodies in the urinary tract, and to minimize stone migration during laser, ultrasonic, electrohydraulic or pneumatic lithotripsy.
How To Use
- Using direct vision or fluoroscopic control, advance the NTrap sheath beyond the stone or foreign object. Deploy the basket by advancing the handle while holding the sheath in position.
- Use an intracorporeal lithotripter to fragment the stone. To avoid damaging the NTrap device when you use laser or electrohydraulic lithotripsy, maintain a gap of at least 1 cm between the stone and the NTrap device. Avoid firing the laser directly on the NTrap.
- Use the basket to gather stone fragments and prevent fragments as small as 1.5 mm from migrating.
- To complete the procedure, close the basket by advancing the sheath while holding the handle in position. Gently advance the basket to disengage stones that are too large for extraction.
Precautions
- Users should be familiar with and experienced in urological endoscopic surgery.
- Assess calculi or other foreign bodies prior to instrument deployment to ensure that object is not too large to be removed through the anatomy.
- If resistance is encountered while attempting to remove calculi or other foreign bodies, release the object. Do not exert excessive force on the device.
- Due to the asymmetric nature of the NTRAP, do not torque or rotate the device in vivo.
- When used in conjunction with holmium: YAG laser, do not fire the laser directly upon the device.
- This device is conductive. Avoid contact with any electrified instrument.
- Enclose device in sheath before removing from tray/holder.
Potential Adverse Events
The following complications are possible with the use of stone extraction devices.
- Tissue perforation
- Tissue evulsion
- Edema
- Hemorrhage
Instructions for Use
- Using aseptic technique, remove the NTRAP from its outer package and place into the sterile field. The NTRAP operating handle is attached to facilitate opening or closing.
- Before insertion, retract the NTRAP basket into the sheath.
- Using direct vision or fluoroscopic control, advance the NTRAP sheath beyond the stone or foreign object prior to deployment.
- Deploy the NTRAP by advancing the handle forward while holding the sheath in position. The device may now be used to minimize stone migration during laser, ultrasonic, electrohydraulic or pneumatic lithotripsy.
NOTE: When using laser or electrohydraulic lithotripsy, a gap of at least 1 cm should be maintained between the stone and the NTRAP to prevent device damage.
NOTE: The NTRAP, in the open position, may be used as an extraction device to sweep the ureter, collecting stone fragments into the bladder. The operating handle may be detached to facilitate scope removal. - Upon completion of the procedure, close the NTRAP basket by pushing the sheath forward while holding the operating handle in position.
- It may be necessary to gently advance the basket to release any remaining stone fragments prior to closing.
