Knitted vascular prosthesis with collagen Ra K incompressible

The knitted crimped vascular prosthesis Ra K incompressible is made of polyester filament yarn using a warp-knitting technology. The front wall of the prosthesis is provided with a color guiding line that makes it easier for the surgeon to know his way in the surgical wound during implantation. A polyethylene monofilament yarn is a wound around the outer side of the prosthesis thus achieving the incompressibility of the graft. A continuous layer of chemically modified bovine collagen is applied to the surface of the prosthesis. It facilitates ingrowth of the tissue into the implant and impermeability of the prosthesis wall at the time of implantation.


  • indicated for all types of reconstruction of arteries
  • especially suitable in the field of extraanatomical reconstructions
  • suitable in reconstructions that bypass the big joints regions
  • elastic and flexible
  • can be cut to any size with scissors without the risk of fraying edges
  • if necessary, the polyethylene monofilament yarn can be removed
  • the water permeability is 0-5
  • supplied in unit packaging
  • sterilized by irradiation
  • the expiration period is 3 years


The knitted vascular prosthesis is indicated for all arterial reconstructions at levels corresponding to the used diameter in relation to the expected flow. Considering its mechanical resistance to changes in its circular lumen shape caused by external pressure or bending in its course through the prosthesis channel, its application is suitable especially in the field of extraanatomical reconstructions and in reconstructions that bypass the big joints regions.
