Technology
LightningWire™ TPS
The LightningWire™ Transseptal Puncture System (TPS), which combines a novel electrosurgical guidewire with a dedicated Activation Cable to simplify procedures using preferred transseptal introducers and existing electrosurgical generators, is now 510(k)‑cleared by the U.S. Food and Drug Administration to create an atrial septal defect in the heart, whereby various cardiovascular catheters are introduced.
Technology
LightningWire
- Proprietary insulation design optimizes electrosurgical performance and mechanical properties along the length of the wire
- Robust distal insulation allows transseptal puncture at low power settings, starting at 15 W1
- 0.032‑inch labeled diameter facilitates broad compatibility with various transseptal devices, including Agilis™ and Swartz™ SL1™
- More than 2× stiffer than the market‑leading 0.035‑inch guidewire to support transseptal delivery of bulky ablation and structural heart devices2
Activation Cable
- Connects to separately cleared electrosurgical generators via industry‑standard monopolar accessory ports
- Does not require a dedicated electrosurgical generator
- Designed to activate only desirable "cut" RF waveforms; cannot activate undesirable "coag" waveforms, which might lead to unwanted thrombus generation3
- Puts control of radiofrequency energy in the operator’s hands on the sterile field, including audible and haptic feedback
Why LightningWire
Efficiency
- Guidewire‑based transseptal puncture minimizes catheter exchanges
- Activation Cable immediately disconnects after transseptal puncture to enable therapy device delivery
- Visible markers facilitate fluoroscopy‑free workflows
Safety
- Compared to crossing at higher power settings, such as 50 W, lower power settings have been associated with reduced thermal injury to inter‑atrial septal tissue4
- Pigtail tip shape minimizes risk of cardiovascular injury after transseptal puncture5
Value
- Since existing electrosurgical generators may be used, capital expense may be eliminated
- Disposable cost is competitive with alternatives
