For Sale ON-X LIFE TECHNOLOGIES INC. CXCS Chord-X Chordal Sizer

ON-X LIFE TECHNOLOGIES INC. CXCS Chord-X Chordal Sizer.

The ON-X LIFE TECHNOLOGIES INC. CXCS Chord-X Chordal Sizer is a specialized surgical instrument used during mitral valve repair procedures. It is a crucial component of Artivion's (formerly CryoLife, which acquired On-X Life Technologies) Chord-X Mitral Chordal Replacement System.


The primary purpose of the Chord-X Chordal Sizer is to assist the cardiac surgeon in accurately determining the optimal length for chordal replacement prostheses when repairing the mitral valve. Mitral valve regurgitation often occurs due to prolapsed or damaged chordae tendineae (the cords that connect the valve leaflets to the heart muscle). Precise sizing is critical for ensuring the repaired valve functions correctly and efficiently.
It serves two main functions:
Selecting Pre-Measured Loops: It helps the surgeon choose the correct length of pre-measured ePTFE (expanded polytetrafluoroethylene) loops from the Chord-X Pre-Measured Loops product line (e.g., 12mm, 16mm, 20mm, 24mm). The sizer typically features a color-coded scale that corresponds to the different pre-measured loop sizes, allowing for quick and accurate selection.
Configuring Custom Lengths: For surgeons who prefer to customize the length of each chord using straight suture material (like the Chord-X Adjustable Suture System), the sizer provides a means to accurately measure and configure those custom lengths.
How it is Used in Mitral Valve Repair:
During mitral valve repair, the heart is typically arrested. The surgeon uses the Chord-X Chordal Sizer in the following manner:
Placement: The sizer has two main components for measurement:
Leaflet Hook: This hook is used to support the free edge of the prolapsed mitral valve leaflet in its desired, non-prolapsed position.
Papillary Hook: This hook is then extended to the planned site of attachment on the papillary muscle.
Sizing: By manipulating a thumb-slide on the sizer's barrel, the surgeon can adjust the distance between the leaflet hook and the papillary hook. This distance directly corresponds to the ideal length required for the replacement chord.
Reading the Measurement: The sizer typically has a scale (often color-coded) that indicates the precise length. This measurement guides the surgeon in either:
Selecting the appropriate pre-measured Chord-X loop: If the sizer indicates, for example, 20mm, the surgeon would then select a 20mm pre-measured Chord-X loop (like the CXL20181220).
Cutting and tying a custom-length chord: If using the adjustable suture system, the surgeon would then cut the ePTFE suture to the determined length and fashion the necessary knots and attachments.
Enhanced Visualization: The sizer's leaflet hook can often be rotated, which helps improve visibility of the valve structures during the sizing process.
Benefits:
Accuracy and Reproducibility: Helps ensure that the new chords are of the correct length, which is crucial for restoring proper valve coaptation and preventing residual mitral regurgitation. This leads to more reproducible surgical outcomes.
Time-Saving: For surgeons utilizing pre-measured loops, the sizer streamlines the sizing process, potentially reducing operative and cross-clamp times, which can benefit patient recovery.
Simplification: Simplifies the complex process of chordal replacement by providing a standardized method for length determination.
In essence, the ON-X LIFE TECHNOLOGIES INC. CXCS Chord-X Chordal Sizer is a precise diagnostic and guiding instrument that plays a vital role in enabling effective and efficient mitral valve repair, especially when using pre-fabricated ePTFE chordal replacement systems.
