Kapsus Transseptal Puncture

What is Kapsus?

Kapsus catheter is an enabling technology that allows a safe, accurate, and controlled transseptal puncture from the right atrium to provide left atrial access. This device is ideal for interventional cardiologists and electrophysiologists seeking tranquility during transseptal puncture procedures.

How does it work?

The device is introduced from the venous side and advanced until its distal tip is positioned in the superior vena cava. The housing is then deployed, anchoring the device in a temporary position. Once the septum is visualized, the physician can verify that the delivery system is perpendicular to the fossa ovalis and then perform the puncture.

Transseptal Puncture Background

Transseptal puncture is a half-century-old procedure performed to gain access to the left atrium by puncturing the fossa ovalis. Current transseptal puncture devices use a needle that is drawn over the heart until the fossa ovalis is located through tactile feedback.

Atrial Housing

Atrial housing is a key component of the Kapsus and a cornerstone of its design. The housing serves as a stable and repeatable alignment to the needle delivery system for puncturing the fossa ovalis. The Kapsus offers perfect safety for the performance of a transseptal puncture.


For the handle, we used a small and elegant design. The operation of the Kapsus consists of a series of steps that are easily and intuitively performed using various components of the handle. The Kapsus handle provides the necessary control for a safe, efficient, and consistent procedure.

Procedural Use

Performing a transseptal puncture with the Kapsus is simple and can be repeated with minimal variation. The Kapsus helps minimize uncertainty while accessing the left atrium.

Kapsus Difference

Why perform a transseptal puncture?

The Kapsus is intended for cardiology procedures that require transseptal puncture. The transseptal puncture approach entails the catheterization of the right atrium with a subsequent penetration of the septum, which is safer than approaching the left atrium through the left ventricle. Transseptal punctures can be performed for diagnostic and therapeutic purposes with minimal risk when done accurately. However, potential complications such as aortic root puncture or tamponade might occur.

Diagnostic use:

  • Pressure measurement in the left atrium
  • Left ventricular access through the mitral valve

Therapeutic use:

  • Mitral valvuloplasty
  • Electrophysiological intervention for catheter ablation
  • Paravalvular leakage
  • Left atrial appendage closure
  • Transfemoral mitral valve procedure e.g. mitra clip

How does Kapsus perform differently compared to other devices?

  • The Kapsus takes advantage of multiple entry points and it relies on reproducible puncture site location methods. Its housing ensures consistency of procedures while managing variability between patients.
