Abstract
An aortic valved tube which is used in human implants to replace the corresponding cardiac valve and ascending section of the aorta itself, incorporates a cardiac valvular prosthesis in its proximal end. The valved tube has two integral branches which project from opposite points with an inclination relative to the longitudinal axis of the tube, which branches are for effecting the anastomosis of the ostiums, corresponding to the left and right coronary arteries, respectively. The branches, as well as the sectors above and below the branches, are reinforced by a thicker wall in those areas while, maintaining the inside diameter of the tube itself.
Claims9
An artificial aortic valved tube implant manufactured of biocompatible material for a human for replacing an aortic valve and an ascending section of an human aorta, comprising:
- a tube of synthetic biocompatible material and of a generally circular cross section, said tube having a proximal end and a distal end, said tube by a tube wall defining a single continuous flow passage between said ends;
- a cardiac valvular prosthesis located within said tube at said proximal end, said flow passage having a substantially constant flow area from said prosthesis to said distal end;
- a first tubular branch of said synthetic biocompatible material and a second tubular branch of said synthetic biocompatible material, each said branch intersecting and extending transversely at different locations from said tube wall and being integral therewith, interiors of said branches communicating with said continuous flow passage of said tube through respective holes in said wall, said branches being located on said wall to facilitate subsequent connection of said branches respectively to left and right coronary arteries of said human.
An artificial aortic valved tube implant manufactured of biocompatible material for a human for replacing an aortic valve and an ascending section of an human aorta, comprising:
- a tube of synthetic biocompatible material which is impregnated with a natural substance and of a generally circular cross section, said tube having a proximal end and a distal end, said tube by a tube wall defining a single continuous flow passage between said ends;
- a cardiac valvular prosthesis located within said tube at said proximal end, said flow passage having a substantially constant flow area from said prosthesis to said distal end;
- a first tubular branch of said synthetic biocompatible impregnated material and a second tubular branch of said synthetic biocompatible impregnated material, each said branch intersecting and extending transversely at different locations from said tube wall and being integral therewith, interiors of said branches communicating with said continuous flow passage of said tube through respective holes in said wall, said branches being located on said wall to facilitate subsequent connection of said branches respectively to left and right coronary arteries of said human.
