Internal shield for a vascular anastomosis

Claim 1

1 . The device for the internal shielding of a vascular anastomomosis end to side characterized by the fact, that is created from a stiff, eventually moderately elastic, biologically inert, unmoistenable, non-resorbable, sterilizable single or combined multielemental material, having the form of the uncomplete two-third tube 4 , which length is minimally five times value of the diameter of the complete tube and in which third and fourth fifth counter to the blood flow is on the convexity formed -the orifice 5 of the length minimally double of the diameter of the complete tube and which width is minimally one quarter of the circumference of the tube, while from the apex of the orifice 5 grows up under the angle 20 to 45 degrees counter to the course of blood flow gradually tapered tongue-like structure 6 at foot wide minimally one quarter of the circumference of the tube, gradually transgressing by the foot 7 into margin 8 of the orifice 5 , so the whole transition does not exceed one third of the orifice 5 and the whole said tongue-like structure 6 is in the longitudinal axis moderately bow-like curved externally, as well as is the margin 8 @f the orifice 5, which is also moderately curved externally and when all margins are blunt and the whole internal surface is highly polished.

Claim 3

The device for the internal shielding of a vascular anastomosis end to side characterized by the fact, that is created from a stiff, eventually moderatelly elastic, biologically inert, unmoistenable, non-resorbable,sterilizable single or combined multielemental material, having the form of the uncomplete two-third tube 4 , which length is minimally five times value of the diameter of the complete tube and in which third and fourth fifth counter to the course of blood flow is on the convexity formed the orifice 5 of the length minimally double of the diameter of the complete tube and which width is minimally one quarter of the circumference of the tube, while from the rear end of the said orifce 5 grows up under the angle 20 to 45 degrees counter to the course of blood flow gradually tapered tongue-like structure 10 at a foot wide minimally one quarter the circumference of the tube, gradually transgressing by the foot 11 into the margin 8 of the orifice 5, so the whole transition does not exceed one third of the length of the orifice 5 and the whole said tongue - like structure 10 is in the longitudinal axis moderately bow-like curved externally as well as is the margin 8 of the orifice 5, which is also moderately curved externally and when all mergins are blunt and the whole internal surface is highly polished.

Claim 4

The device for the internal shielding of a vascular anastomosis end to side characterized by the fact, that is created from a stiff, eventually moderatelly elastic, biologically inert, unmoistenable, non-resorbable,sterilizable single or combined multielemental material, having the form of the uncomplete two-third tube 4 , which length is minimally five times value of the diameter of the complete tube and in which third and fourth fifth counter to the course of blood flow is on the convexity formed the orifice 5 of the length minimally double of the diameter of the complete tube and which width is minimally one quarter of the circumference of the tube, while from the rear end of the said orifce 5 grows up under the angle 20 to 45 degrees counter to the course of blood flow gradually tapered tongue-like structure 10 at a foot wide minimally one quarter the circumference of the tube, gradually transgressing by the foot 11 into the margin 8 of the orifice 5, so the whole transition does not exceed one third of the length of the orifice 5 and the whole said tongue - like structure 10 is in the longitudinal axis moderately bow-like curved externally as well as is the margin 8 of the orifice 5, which is also moderately curved externally and when all mergins are blunt and the whole internal surface is highly polished.

Claim 5

The device for the internal shielding of a vascular anastomosis end to side characterized by the fact, that is created from a stiff, eventually moderately elastic, biologically inert, unmoistenable, non-resorbable, sterilizable, single or combined multielemental material, having the form of the uncomplete two-third tube 4 , which length is minimally five times value of the diameter of the complete tube and in which third and fourth fifth counter to the course of blood flows on the convexity formed the orifice 5 of the length minimally double of the diameter of the complete tube and which width is minimally one quarter of the circumference of the tube, while from the apex of the orifice 5 grows up under the angle 20 to 45 degrees counter to the course of the blood flow gradually tapered tongue-like structure 6 at foot minimally one quarter of the circumference of the tube, gradually transgressing by the foot 7 into margin 8 of the orifice 5 , so the whole transition does not exceed one third of the length of the orifice 5 and simultaneously from the rear end of the orifice 5 grows up under the angle 20 to 45 degrees gradually tapered tongue-like structure 10 at foot wide minimally one quarter of the circumference of the tube, gradually transgressing by the foot 11 into the margin 8 of the orifice 5 so the whole,transition does not exceed on third of the length of the orifice 5 , while the tongue-like structure 6 growing up from the apex of the orifice 5 as well as the tongue-like structure 10 , growing up from the rear end of the orifice 5 are both moderately bow-like curved externally, as well as-the margin 8 of the orifice 5 , which is also moderately curved externally, while all margins are blunt and the whole internal surface is highly polished.

Claim 6

The device for the internal shielding of a vascular anastomosis end to side characterized by the fact, that is created from a stiff, eventually moderately elastic, biologically inert, unmoistenable, non-resorbable, sterilizable, single or combined multielemental material, having the form of the uncomplete two-third tube 4 , which length is minimally five times value of the diameter of the complete tube and in which third and fourth fifth counter to the course of blood flows on the convexity formed the orifice 5 of the length minimally double of the diameter of the complete tube and which width is minimally one quarter of the circumference of the tube, while from the apex of the orifice 5 grows up under the angle 20 to 45 degrees counter to the course of the blood flow gradually tapered tongue-like structure 6 at foot minimally one quarter of the circumference of the tube, gradually transgressing by the foot 7 into margin 8 of the orifice 5 , so the whole transition does not exceed one third of the length of the orifice 5 and simultaneously from the rear end of the orifice 5 grows up under the angle 20 to 45 degrees gradually tapered tongue-like structure 10 at foot wide minimally one quarter of the circumference of the tube, gradually transgressing by the foot 11 into the margin 8 of the orifice 5 so the whole,transition does not exceed on third of the length of the orifice 5 , while the tongue-like structure 6 growing up from the apex of the orifice 5 as well as the tongue-like structure 10 , growing up from the rear end of the orifice 5 are both moderately bow-like curved externally, as well as-the margin 8 of the orifice 5 , which is also moderately curved externally, while all margins are blunt and the whole internal surface is highly polished.

Claim 9
