Solution

Catheter Based Solution

CathHELIX is a catheter based mitral repair concept which is in an advanced development phase. It is based on our patented helix ring technology utilizing the anatomy of the heart and enabling a less complex but clinically efficient method that has the potential to reduce the invasiveness, operation time and morbidity associated with current mitral valve operations.
CathHELIX is introduced from the groin through atrial septum to the left atrium. The implantation is done by rotating the helical ring from posterior commissura into its intended position. The rotation ensures that the implant is correctly positioned having one of the loops above and the other one below the mitral annulus.

Surgical Solution

The currently available single loop annuloplasty rings are introduced on top of the mitral annulus and connected on the annulus using a parachute suture technique. The enlarged mitral valve is downsized by the placement of several (generally over 12) sutures. The parachute suture technique is time consuming and requires significant surgical skill and experience.
Medtentia’s Helix concept utilizes the anatomy of the heart. The helix ring is inserted by rotating it 360° from posterior commissura into its intended position. The rotation ensures that the helix ring is correctly positioned having one of the loops above and the other one below the mitral annulus.
Remodeling of the Annulus and prevention of secondary distortion of the annulus is secured by suturing annulus to the ring after the implantation.

Advantages

Medtentia’s helix-based solutions (catheter based and surgical) are expected to provide significant advantages over the existing methods in treatment of mitral valve disorders:

  • Easy to learn and use
  • Reduced implantation and fixation time
  • Less sutures needed (surgery)
  • Consistent results due to anatomical guiding
  • Utilize mini-invasive surgery techniques
  • Improve the safety of operations
  • Shorter cardiopulmonary bypass time allows treating patients not treated today (surgery)
  • Operate patients that undergo complex concomitant cardiac procedures
  • Treat patients for whom the surgery is considered too risky todays

 

Terminology

Mitral Annulus/Annulus Ring
An artificial ring that is attached to the mitral valve leaflets to treat the mitral valve regurgitation. The annulus contracts and reduces its surface area during systole to help provide complete closure of the leaflets.

Perfusion
The process where fluid (often blood) is injected via a blood vessel to a specific tissue or organ (like the heart) to deliver oxygen or nutrients. Perfusion is used in open heart surgery where the function of the heart is temporarily arrested.

Tricuspid Valve
One of the four heart valves located on the right dorsal side of the human heart, between the right atrium and the right ventricle. Ensures the blood flows in a forward direction from the right atrium to the ventricle. Consists of three leaflets connected to three papillary muscles by the chordae tendineae.
