Simplici-T Annuloplasty System

Surgical Valve Repair


The Simplici-T annuloplasty system offers a first-of-its-kind approach to mitral and tricuspid valve repair.


This device is indicated for the reconstruction and/or remodeling of pathological mitral and tricuspid valves. Appropriate repair and annular remodeling may correct combined valvular insufficiency and stenosis.

Product Details

Repair Redefined

The Simplici-T system is the first flexible band to eliminate the need for traditional sizing, providing a custom fit for every patient and requiring less inventory space.

Correct annuloplasty band sizing is an important element to achieve a successful repair.

No more sizing

One size is always the right size. The Simplici-T System is based on the “no sizing” implant technique of Dr. Tirone David.

Customized for every patient

The flexible band adapts to the unique needs of every patient. Implanted band length is determined by the annular size and degree of plication of the annular tissue.

Reduced inventory

The flexible annuloplasty band is supplied in a length of 100 mm and requires no additional accessories.

Offers the benefits of a flexible band, including:

  • Better early postoperative LV systolic function over patients with a rigid ring1
  • Allows annulus size and configuration to adapt to changes throughout cardiac
  • Better diastolic blood flow across the mitral valve, particularly during exercise5
  • Flexible annuloplasty repair devices place less stress on the sutures during systole, minimizing the likelihood of dehiscence6

'I have not sized a mitral valve for an annuloplasty band for more than a decade. Simplici-T allows the surgeon to tailor the length of the band according to the pathology.'
Tirone E. David, M.D.*
