The TSP Crosser is an integrative solution for reproducible and controllable transseptal puncture, all in one system.
The growth of left-side transcatheter procedures holds great promise but is hindered by the need for advanced operator skills in transseptal puncture. Transseptal Solutions’ technology reduces dependence on trained operators with dedicated technologies that benefit procedural efficiency and may prevent complications.

By addressing significant but unmet market needs, Transseptal Solutions improves left atrial access procedures with an innovative approach that will enable expanding indications of left-side heart treatment.


The TSP Crosser, CE marked & FDA approved, is an integrated transseptal system that includes an innovative method to engage the fossa ovalis precisely and efficiently. The TSP CrosserTM uses an extendable radiopaque loop wire and a steerable sheath to precisely navigate a flexible needle for an accurate transseptal puncture. After the puncture, the steerable sheath serves as a guiding catheter for optimal left atrial access for various left-side procedures:
Transcatheter mitral repair/replacement
Mitral paravalvular leaks 
AF & VT ablation 
LAA occlusion
Inter-atrial shunts

TSP Crosser Benefits
Allows fossa ovalis boundaries to be visible, resulting in better targeting
-Precise “pre-puncture steering” for accurate positioning 
-Stabilizing loop offers enhanced puncture dynamics 
-Improved steerability system (+/- 180°) for superior navigation 
-Short learning curve
-Reproducible, all in one system saves time
