Description

A kind of aortic blood pipe holder

Technical field:

The present invention relates to a kind of intravascular stent of inserting in the ascending aorta.

Background technology

Ascending aorta blastoma or dissecting aneurysm are the common aortic distensibility diseases of aortic root.Along with the progressively expansion of tumor body, finally can break causes death; Perhaps cause aortic incompetence, and then cause heart failure.Now, can only carry out traditional surgical intervention to this pathological changes, modal modus operandi is " aortic valve replacement+coronary reconstruction+ascending aorta displacement ", sometimes even need carry out the reconstruction operations of aortic arch displacement and brachiocephalic artery.This operation usually need be at profound hypothermia, stop circulating, carry out under the condition of extracorporeal circulation.Therefore, operating time is long, wound is huge, complication is many, mortality rate is high, and this surgical technic is difficult to be popularized.And because the outlet of tumor body near-end next-door neighbour left ventricle, technology in the lumen of vessels does not have the pathological changes of good proximal landing zone must not carry out intracavitary therapy.

Summary of the invention

The invention provides a kind of aortic blood pipe holder, can realize intracavity reconstruction coronary artery and ascending aorta.

The technical solution used in the present invention is: be provided with circular open on the sidewall of trunk support, by above-mentioned opening tubular branch be placed in the coronary artery.The end that sub-stent is communicated with the trunk support is a horn shape, and horn mouth place diameter is greater than the circular open diameter of trunk support.

Sub-stent can be two, respectively with the sidewall of trunk support on two symmetric open communication.Also can establish biological know-how's arterial valve film at the trunk support near heart one end.Trunk support and sub-stent appearance also can cover artificial blood vessel.Sub-stent also can expand cribbing type blood vessel for ball.

The present invention is with the split compound mode, trunk support in the ascending aorta is connected with sub-stent in the coronary artery, formed good proximal landing zone, the aortic root dilatancy disease of the aortic incompetence that can effectively treat ascending aorta blastoma, dissecting aneurysm, causes because of aortic aneurysm.Reduce the corrective surgery wound simultaneously.

The specific embodiment

The present invention is further described below in conjunction with accompanying drawing:

Be illustrated in figure 1 as the sketch map of first embodiment of the invention, shown in the aortic blood pipe holder, comprisetrunk support 1 andsub-stent 6,8, twoopenings 3,4 are arranged ontrunk support 1 sidewall, opening 3,4 positions are according to patient's coronary ostiumset positions.Sub-stent 6,8 has two, is communicated withtrunk support 1 at two openings, 3,4 places of above-mentionedtrunk support 1 sidewall respectively;Trunk support 1,sub-stent 6,8 are to cover artificial blood vessel 2,7 on the bare bracket to constitute, andsub-stent 6,8 expands cribbing type blood vessel for ball.

The installation process of present embodiment is as follows:trunk support 1 and twosub-stents 6,8 with the aortic blood pipe holder are compressed in the suitable induction system earlier, the trunk support drives in the wrong direction through femoral artery,common along induction system and strides aortic arch, be released to the aortic root correct position, locatingaperture 3,4 is in the position of left and right sidescoronary artery 10,11 opening correspondences.Then,sub-stent 6,8 is under the effect of induction system seal wire, and theopening 3,4 that passestrunk support 1 enters left and right sidescoronary artery 10,11 respectively, and at the expansion compacted under of induction system sacculus.

As Fig. 2,sub-stent 6,8 forms trumpet type neartrunk support 1 one ends, is installed in thetrunk support 1 by opening 3,4, thereby realizes intracavity reconstruction coronary artery and ascendingaorta 9.

Fig. 3 is another embodiment of the present invention sketch map, is biological know-how'sarterial valve film 5 at close heart one end of trunk support 1.Trunk support 1,sub-stent 6,8 are to cover artificial blood vessel 2,7 on the bare bracket to constitute, andsub-stent 6,8 expands cribbing type blood vessel for ball.Adopt biologicalaortic valve 5, can realize intracavity displacement aortic valve.

Be illustrated in figure 4 as the scheme of installation of second embodiment of the invention.Earlier thetrunk support 1 of aortic blood pipe holder and twosub-stents 6,8 being compressed in the suitable inductionsystem trunk support 1 drives in the wrong direction through femoral artery,common along induction system and strides aortic arch, be implanted in the proper site of aortic annulus, lobe and ascendingaorta 9, the biologicalaortic valve 5 of close heart one end in location is adjustedopening 3,4 in the position of left and right sidescoronary artery 10,11 opening correspondences simultaneously in from the aortic valve place of body incompetence; Then,sub-stent 6,8 is under the effect of induction system seal wire, and theopening 3,4 that passestrunk support 1 enters left and right sidescoronary artery 10,11 respectively, and at the expansion compacted under of induction system sacculus.

Biological know-how'sarterial valve 5 thattrunk support 1 is installed near the heart end has been replaced the aortic valve from the body incompetence, by twoopenings 3 on thetrunk support 1,4, guaranteed that trunk support 1 inserting a process cardiac left side, rightcoronary artery 10,11 have lasting supply of blood flow, aftertrunk support 1 is inserted and is finished, again with twosub-stents 6,8 pass above-mentioned twoopenings 3 respectively, 4, be presented in the coronary artery, by induction system balloonexpandable sub-stent 6,8 ends neartrunk support 1,sub-stent 6,8 with an end oftrunk support 1 UNICOM be horn shape, horn mouth place diameter is greater than the circular open diameter of trunk support,sub-stent 6,8 are installed ontrunk support 1 inwall, under the effect of blood pressure, closely be connected withtrunk support 1, twosub-stents 6,8 provide biological know-how'sarterial valve 5 and artificial blood vessel 2,7 are anchored on the support force on aortic annulus and ascendingaorta 9 walls, use the artificial blood vessel 2 that covers support, 7 have completely cut off the impact of blood flow to aortic aneurysm.Like this, the aortic disease of treatment ascending aorta tumor interlayer and aortic incompetence only needs the little otch of inguinal region just can finish, and does not also need profound hypothermia, stops circulating, the surgical condition of extracorporeal circulation, has avoided the open chest surgery of huge wound.
