Intended Use

For use in the treatment of hydrocephalus as a component of a shunt system when draining or shunting of cerebrospinal fluid (CSF) is indicated.

Device Story

The Codman Libertís Shunt Catheter is a component of a CSF shunt system used to treat hydrocephalus. It consists of ventricular and distal (peritoneal) drainage catheters that connect to a shunt valve. The ventricular catheter diverts excess CSF from brain ventricles through the valve; the distal catheter drains CSF into the peritoneal cavity for reabsorption. The catheters are made of platinum-cured silicone impregnated with rifampicin and clindamycin hydrochloride to reduce gram-positive bacterial colonization. Endexo polymer is blended into the silicone to improve hemocompatibility. The device includes a stylet for insertion and a right-angle adapter for cranial fixation. It is used by neurosurgeons in clinical settings. The device features radiopaque barium sulfate stripes and ink markings for positioning. By reducing bacterial colonization and thrombus deposition, the device aims to improve shunt performance and patient outcomes. It is MR-safe.

| 807.92(a) (4) Device Description | |
| The Libertis™ Shunt Catheter includes a ventricular and distal (peritoneal) drainage catheter that are used as part of a cerebrospinal fluid (CSF) shunting system to treat hydrocephalus. Both catheters are attached to the valve portion of a shunting system. The ventricular catheter diverts excess CSF from the ventricles of the brain through the valve. After passing through the valve, the excess CSF is drained through the distal catheter into another part of the body, such as the peritoneal cavity, where it is reabsorbed into the bloodstream. The catheters have Endexo® polymer, a surface modifying macromolecule, blended into their base silicone. The catheters are subjected to a treatment process by which the silicone is impregnated with two antimicrobials, rifampicin and clindamycin hydrochloride. The Libertis™ Shunt Catheter has been shown in laboratory studies to reduce the colonization of gram-positive bacteria on the tubing surface. The catheters contain barium sulfate for radiopacity and have ink markings on the silicone tubing to aid in positioning of the catheter. The catheters are packaged with two accessories, a stylet and a right-angle adapter. The stylet is used to help introduce the ventricular catheter into the brain’s ventricles. The right-angle adapter is used to fixate the ventricular catheter to the cranium. | |
| 807.92(a) (5) Indications for Use | |
| For use in the treatment of hydrocephalus as a component of a shunt system when draining or shunting of cerebrospinal fluid (CSF) is indicated. | |
| 807.92(a) (6) Technological Characteristics Compared to Predicate | |
| The Libertis™ Shunt Catheter has the same intended use, same functionality, same antibiotics, same radiopaque material, and similar design specifications as the predicate device. Compared to the predicate, the proposed device adds a new material, Endexo®, is made of an equivalent silicone, has markings made of ink instead of tantalum, offers a new length of ventricular catheter and stylet, and uses different packaging materials. The differences in technological characteristics do not raise different questions of safety and effectiveness, compared to the predicate. | |

| Component Affected | Proposed Modification | Rationale |
| --- | --- | --- |
| Catheters Materials | The proposed device and the predicate device are made of base silicones from different manufacturers.
Addition of Endexo® additive to the base silicone in the proposed device. | The proposed device is made of implant-grade platinum-cured silicone, equivalent to that of the predicate.
Endexo® is a surface modifying macromolecule (SMM) polymer blended into the catheter’s base silicone. |
| Ventricular Catheter Markings | The proposed device’s markings consist of numbers with circumferential bands, which are made of implant-grade ink and silicone adhesive. The predicate device’s markings consist of tantalum dots.
The proposed device also has additional markings compared to the predicate device. | The addition of numerical markings and circumferential bands is part of continuous improvement in catheter usability. |
| Ventricular Catheter Length | The proposed device’s ventricular catheter comes in 14 cm and 23 cm lengths. In comparison, the predicate device’s ventricular catheter only has a 14 cm option. | Adding a 23 cm ventricular catheter supports the variety of approaches and valve placements used in hydrocephalus shunting. |
| Ventricular Catheter Inlet Holes | The proposed device has a smaller number of inlet holes, compared to the predicate devices. The inlet holes in the proposed device are of different size and shape, and have a different spatial arrangement, compared to the predicate. | The change in the number, size, shape, and spatial arrangement of the inlet holes is part of continuous improvement in catheter usability. |
| Stylet | The stylets of the proposed device have a square shaped cross section, compared to a circular shape in the proposed device’s stylet.
A longer stylet is paired with the longer ventricular catheter (23 cm). | The square shaped cross section of the stylet is part of continuous improvement in catheter usability.
The longer stylet is required for aiding the insertion of the new 23 cm ventricular catheter. |
| Ventricular and Distal Catheters Radiopacity | Both the proposed and predicate devices use barium sulfate for radiopacity. The proposed ventricular and distal catheters are translucent with a radiopaque stripe along the entire length of the catheter | The use of a barium sulfate stripe in a translucent catheter is part of continuous improvement in catheter usability. |

| | tubing. In comparison, the predicate device is fully radiopaque. | |
| --- | --- | --- |
| Packaging | The predicate and the proposed devices use a double sterile barrier system composed of a sealed tray/lid system inside a sealed pouch. Some of the components of the packaging systems are made with different materials. | The differences in packaging materials are intended to support sterilization and to reduce degradation of the antibiotics in the catheters. |

In addition to the differences in the materials and design of the proposed and the predicate devices, the devices are sterilized using different methods and have different MRI compatibility. The proposed device is sterilized using E-beam radiation while the predicate is sterilized using steam. Both sterilization methods achieve the same Sterility Assurance Level (SAL = 10⁻⁶). The proposed device has an MR-safe designation while the predicate has an MR-conditional designation. The difference in MRI compatibility is due to the absence of tantalum, a metallic alloy, in the markings of proposed device.
