Device for occlusion of left atrial auricle

Description of the device

Device for occlusion of left atrial auricle is a percutaneous device for preventing embolization of blood clots from the left atrial auricle of patients with atrial fibrillation.
Device for occlusion of left atrial auricle completed by a delivery system.

Technical characteristics

The product is made of high-tech nitinol mesh on a complexly modeled frame, which is sent with a polyester fabric from the inside;

  • The construction of the occluder consists of two disks, also construction is self-opening and self-centering.
  • On the surface of the occluder there is a number of fixing elements which impede the migration of the product from the left atrial auricle.

The system of the delivery of the occluder of left atrial auricle (includes the transeptal introducer, the bougie for the delivery catheter, pusher of occluder of left atrial auricle).

For implantation of device for occlusion of left atrial auricle in X-ray conditions there are require the following materials:
