Ablate with Deeper Insights

INTELLANAV STABLEPOINT™ Ablation Catheter, featuring DIRECTSENSE™ Technology, combines the power of contact force and local impedance to give you dynamic insights at and below the cardiac tissue surface.

Unlike any other technology, this integrated solution, available exclusively via RHYTHMIA HDx™, enables you to diagnose, ablate, and validate with more critical information than ever before.

Intro
Contact

Contact Force & Local Impedance

Learn about the enhanced catheter design and how contact
force and local impedance work in parallel to deliver
complementary information.


Catheter Design

The force design combines a spring and inductive sensors to capture gram measurement via force applied. The advanced laser cut spring maintains sensitive performance during use while three inductive sensors work together to translate sensor displacement for angle and force visualization.
The catheter features ergonomic handle enhancements and an updated shaft construction with a stainless-steel braid extending from proximal to distal end designed to provide torque transfer, tip stability, and curve retention.

Contact Force & Local Impedance

Verify Contact1

Prior and during ablation, the addition of force technology to local impedance provides doctors the confirmation of mechanical contact and catheter tip-to-tissue stability.

 

Confirm Contact & Stability for RF Delivery Duration

In this study, force readings enabled two independent users to maintain a stable average force of +/- 5 grams, compared to starting force, for the full duration of >90% of point-by-point PVI applications.

Discern Tissue Types

Discern Tissue Types2

Once contact is established, doctors can utilize local impedance to distinguish tissue types prior to ablation to understand the potential to deliver effective RF energy.

 

Substrate Characterisation to Help Understand Tissue Resistivity

The local impedance measurement is sensitive to tissue substrates as shown in this study, and because it is a measure of tissue resistivity, it can help guide the ablation strategy for various tissue types.

Monitor Subsurface Tissue Heating

During ablation, changes in local impedance allows doctors to interpret real-time feedback into lesion development and safeguards to help prevent overheating.

 
Local Impedance Drops Highly Correlated to Intra-Lesion Temperature

Local Impedance Drops Highly Correlated to Intra-Lesion Temperature

Tissue tests with embedded thermocouples showed that local impedance drop dynamically followed the rate and magnitude of intra-lesion temperature rise. This demonstrated the relationship between local impedance feedback and volumetric heating as it occurs.

Deliver Predictable and Controlled RF

Deliver Predictable and Controlled RF1,2,4

Using local impedance and force data, doctors can determine optimal RF titration by applying efficient and precise ablation at the right power for the right duration.

 

Optimize RF Duration
At Preferred Power

In this study, where PVI RF applications using local impedance and force, median RF duration at 50W and 30W powers were reduced by 30% and 20% respectively compared with RF applications that relied only on force, time, and power inputs. There was no difference of effectiveness which showed the addition of local impedance provided real-time feedback into lesion development to optimize RF duration.
