BOLT, DRILL and Accessories for Neuromonitoring

To implant the catheter, the cranium is penetrated with a DRILL and the suitable DRILL bit. The DRILL bit size is selected to match the diameter of the catheter.

The DRILL bit is disposable for single use only as bone is dense and can cause the DRILL bit to become dull. If the DRILL is dull, the friction creates high temperatures and will lead to thermal damage in the bone, which will negatively affect the healing of the bone.

The DRILL KIT matches the diameter of the catheter and is offered in CH5 for parenchyma catheters and CH9 for ventricular catheters. Each DRILL KIT comes with an Allen key to adjust the depth of the stopper on the DRILL.

To safely position the catheter, a BOLT is screwed into the drilled hole. A Screwing in tool is used to position the BOLT into the skull creating a tight seal. The catheter is firmly secured into the BOLT with the help of a flexible sealing cap. The BOLT KIT is available in two versions: CH5 (for parenchyma catheters) and CH9 (for ventricular catheters).

The BOLT KIT PTO 2L is a 2 lumen BOLT, which provides secure positioning of the NEUROVENT-PTO 2L  and microdialysis catheters through a single access port.

The flexible lumens of the BOLT KIT PTO 2L allows the catheters to be bent so they do not get caught on CT scanners.  The dimension of the BOLT KIT PTO 2L is CH9.

A tunnel can be created below the scalp to safely positioning intracranial catheters. Using the Spliceable Tunneling Sleeve, the catheter is pulled through the tunnel then the sleeve is spliced and removed leaving the catheter in place. The subcutaneous tissue surrounds the catheter very tightly; however it creates a more significant surgical trauma than the BOLT. The Spliceable Tunneling Sleeve is available in two versions: CH8 for parenchyma catheters and CH12 for ventricular catheters.

Depending on which catheter is implanted different cables are available to directly connect to the temperature and pressure ports on the patient monitors. These connection cables interface with all commonly used patient monitors. For transferring the ICP (intracranial pressure) to the patient monitor, the ICP-TEMP-Cable is required, which serves as an extension from the catheter to the patient monitor. For transferring the temperature parameter, the ICP-TEMP-Adapter is required (Philips/HP monitor requires a specialised ICP-TEMP-Adapter).

The Zero-Point Simulator NPS2 is attached directly to the pressure port of the patient monitor. All RAUMEDIC catheters are calibrated in the manufacturing process to eliminate possible errors that can occur when zeroing the catheter. The Zero-Point Simulator NPS2 is used to transfer the 'zero' to the patient monitor.

The NPS3 is a battery operated device to allow pressure measurement to occur while the patient is being transferred. The ICP-TEMP-Cable can quickly and easily be disconnected from the NPS2 and connected to NPS3.
