 Velum ® - Pumonary Valved Conduit with L-Hydro ®

A bovine pericardial conduit with a pulmonary porcine valve inserted at mid-segment of the conduit, with distal and proximal portions of graft fully opened. Blood flow direction is clearly indicated by external suture marks at mind-section, at the point where pulmonary valve is located.

These features make Velum®  the best solution for congenital diseases, palliative or definitive procedures.

Indications: Velum® is indicated for Reconstruction of the Right Ventricular Outflow tract (RVOT) in patients less than 18 years of age.

Can also be used in the following congenital pathologies:

  • Pulmonary Stenosis
  • Pulmonary Atresia
  • Tetralogy of Fallot
  • Truncus Arteriosus
  • Transposition with Ventricular Septal Defect

Available sizes: 11*, 13, 15, 17, 19*, 21*mm.

(*Available thru special order.)

Tecnologia L-Hydro

Fundaments of the L-Hydro Process

- Present to the receiving organism an acellular matrix very similar to the natural one;
- Allow the cell growth to take place under the conditions in which the graft exercises its function. Thus, not only the collagen matrix would be identified as stimulated, but also the physiological conditions in which the graft is found, avoiding the intensive work and time spent with the traditional tissue engineering.

L-Hydro Preservation Process

- Moderate extraction of antigenic substances.
- Concealing the antigens not extracted by an activated polyglycolic agent.
- Moderated chemical process to stimulate the reduction of components that induce inflammatory responses in the receiver.
- Incorporation of a non-steroid anti-inflammatory agent.
- Incorporation of the anti-thrombogenic agent.
- Chemical sterilization with hydrogen peroxide.
