Quadripolar LV Leads / ACUITY™ X4 Quadripolar LV leads are the first and only LV leads uniquely designed to promote non-apical pacing options, helping physicians to pace from an optimal site for improved CRT response.
ACUITY X4 leads are designed to improve delivery and optimize pacing performance.
The ACUITY X4 family of leads include 3 unique electrode configuration choices across multiple tip shapes, each offering the industry’s smallest 2.6F tip and 5.2F lead body.
- The industry’s only quadripolar LV lead family that offers dual fixation through 3D spiral and tined fixation mechanisms
- Long, straight tapered tip for accessing tortuous anatomy
- Inner catheter deliverable
ACUITY X4 offers Unique 3D Spiral Shape.
- 3D shape presses electrodes against vessel walls, improving threshold performance of proximal electrodes
- Electrodes oriented around the circumference of the spiral to increase chances that at least one of three electrodes will be adjacent to the myocardium in any coronary vasculature location
ACUITY X4 leads are redefining quadripolar pacing to improve CRT response.
Because the electrodes are uniquely placed around the circumference of the lead, the 3D spiral models are able to overcome challenges in mid-base (proximal) ventricular regions.
- ACUITY X4 leads offer multiple electrode configuration options to promote non-apical pacing within even the most complex vasculature
- Designed to place more electrodes in a mid or basal location.
- Proximal location may increase your chances of pacing non-apically
