Heartstring III Proximal Seal System

Heartstring III Proximal Seal System

Heartstring III brings proximal anastomotic technology into the future. A hemostatic seal enables surgeons to eliminate partial occlusion clamps and minimize aortic manipulation during proximal anastomosis that can lead to complications1.


When it comes to a stroke, leave nothing to chance.

The Heartstring III proximal anastomotic seal technology allows for clampless hemostasis during proximal anastomosis when performing CABG procedures. It allows hand suturing without using either the cross clamp or the side-biting clamp.

Heartstring III Proximal Seal System consists of 3 components

Aortic Cutter

Aortic Cutter

The Aortic Cutter is easy to use, and makes a single, clean hole in the aorta.

Seal loader and delivery device

Loader and Delivery Device

The innovative loading device makes the Heartstring III proximal seal placement fast and easy.

Proximal Seal


The Heartstring III Proximal Seal is an innovative advance in proximal anastomotic seal technology.


Minimizing the manipulation of the ascending aorta reduces the risk of neurologic complications. In patients with minimal aortic disease the cerebral emboli number is significantly reduced when the Heartstring III device is used.1


Allows use of the surgeon’s own hand sewn and angled take-off technique for optimal anastomotic quality and procedural flexibility.


The loading device and aortic cutter make Heartstring III seal placement fast and easy.


Beating Heart Surgery

Off-pump coronary artery bypass (OPCAB) uses local stabilization of the heart that allows the surgeon to operate while the heart still beats. In contrast, conventional bypass surgery stops the heart and puts the patient on a heart-lung machine during the bypass procedure.

The potential benefits of beating heart surgery compared to on-pump surgery may include:[4]

  • Reduced incidence of a common irregular rhythm post-operatively (AFib)
  • Fewer cognitive and neurological effects (for example, a stroke)
  • Lower incidence of post-operative respiratory failure
  • Faster recovery rates
  • Shorter hospital stays
  • Fewer wound complications
  • Fewer blood transfusions needed
