Subdural Evacuating Port System

SEPS Subdural Evacuating Port System

The SEPS Subdural Evacuating Port System provides an innovative, minimally invasive procedure that allows the caregiver to remove a chronic or subacute subdural hematoma at the patient’s bedside.

About SEPS

The SEPS Subdural Evacuating Port System is an innovative, patented technology for the treatment of chronic and subacute subdural hematomas and is also indicated for the treatment of hygromas. SEPS is an improvement over previous methods as it can be used at the bedside under local anesthesia and uses a smaller burr hole than other subdural evacuation methods.

SEPS allows for the gradual re-expansion and recovery of the brain, reducing further trauma to the brain’s fragile structures as it decompresses.

  • The SEPS procedure can be done at the bedside using local anesthesia
  • Only a 5 mm drill hole is required
  • The evacuation port is designed to not enter the subdural space
  • No irrigation, aspiration, or catheter is required
  • SEPS provides a closed system for hematoma evacuation
  • SEPS extradurally establishes a uniform negative pressure for consistent evacuation, gradual decompression, re-expansion, and recovery of the brain

How SEPS Works

The minimally invasive Subdural Evacuating Port System (SEPS) is a closed system that uses uniform negative pressure to gradually evacuate hygromas and chronic and subacute subdural hematomas.

In the SEPS procedure, the evacuating port does not enter the subdural space. It does not require an operating room and can be set up at the patient’s bedside under local anesthesia using a 5 mm burr hole. Current methods require 20 – 30 minutes to set up versus the SEPS procedure which can be done in 10 minutes.

Important Safety Information

In addition to the risks associated with any brain surgical procedure, such as bleeding, damage to surrounding brain tissue, seizures, stroke, or death, the following complications may also occur: foreign body reactions; bacterial contamination of the wound, wound abscess, fistula formation, and herniation of tissues at the site of the evacuating port; pneumocephalus; obstruction of the system by kinking the tubing or plugging the tubing or port with blood clots or bone particles, and disconnection of the system.

These complications, as well as persistent or recurring subdural effusion or inadequate placement of the evacuating port may require follow-up surgery such as the need to reposition the port, the placement of a second port, percutaneous needle aspiration or craniotomy.

At times the common complications can provide serious risks and should be treated promptly as such. It is important to review the product labeling for complete safety information, potential complications, contraindications, and a complete explanation of warnings and precautions.
