Bicuspid valve intervention replacement and aortic valve replacement between left atrium and the left ventricle are known.Traditional therapy is to sew on the artificial valve again after the Bicuspid valve of own pathological changes and the aortic valve excision (surgery is opened breast).
In addition, Chinese utility application CN1961845A discloses a kind of artificial heart stent valve.This stent valve comprises pipe-shaped net rack, valve leaflet, diaphragm seal, radiopaque marker and flexibly jointed chain ring.The stage casing of network wherein can be tubular or cydariform, or is provided with radial protrusion structure, or is provided with outer circulus, or is provided with outer free tongue, or is provided with radial protrusion structure and adds outer free tongue.This stent valve shape, 26S Proteasome Structure and Function are more optimized; But radial compression is accurately carried under intervention device helps and is put in place, expansion then, and the man-made support valve after expansion discharges can not produce perivalvular leakage in the radial and axial blood vessel wall shape that meets; Can bring into normal play after the implantation effect of valve can prevent that when the blood reflux valve is closed blood causes the artificial valve to slide in the other direction.
Above-mentioned stent valve can not reclaim and change the position after implantation.Will bring danger to patient in case placement is improper when implanting.
The utility model content
The purpose of this utility model provides a kind of band lobe device, and this band lobe device has support force, can reclaim before discharging fully, so that adjusting position.
This utility model provides a kind of band lobe device, and it comprises: support; Be positioned at the valve of support; The connecting device that is connected separably with a conveyer device that is positioned at mount proximal end or far-end.
The far-end of described band lobe device is the corolla shape under the natural expansion state, is attached on the heart wall so that help.
Comparatively speaking, the far-end elasticity of described support is moderate, and the elasticity of the holder part at support valve place is soft, and the resilient beam of near-end.
This support is netted.
This band lobe device can be made into the shape of tubulose or body internal channel, and this band lobe device has support force and adhesion, can directly be connected with the body internal channel or adhere to.
The support of this band lobe device part is made by the metal or the synthetic material that design according to body internal channel characteristics and function.Support can be designed to self-expanding or expanded device according to anatomical structure.
This support epicoles fabric texture or synthetic material fabric.This tissue or synthetic material fabric are connected by stitching, braiding or adhesion with support, can increase adhesion and applying power with the body interior conduit simultaneously.
Mount proximal end can be designed to the supporting construction that support force is strong, the interval is big according to anatomical structure; Far-end can be designed to density height, structure that pliability is good.
Described valve is made by biological tissue or synthetic material or metal, sews up or is woven in the support.
Support, outer attached tissue or fabric are designed to avoid the composition structure of the blood supply opening of tremulous pulse, opening for example coronarius jointly.
The connecting device with a conveyer device is connected separably that is positioned at mount proximal end or far-end is a mechanical connecting device, and for example screw connection perhaps is the junction point of a plurality of fusible.
The utility model has the advantages that owing to used the connecting device that is connected separably with a conveyer device that is positioned at mount proximal end or far-end, before this band lobe device is discharged fully, can adjust its position, after adjust fully the position, again connecting device is separated with conveyer device, thereby can guarantee good location with the lobe device.

The specific embodiment
As Figure 1-3, band lobe device 1 of the present utility model is a kind of band lobe device that support and adhesive capacity are arranged of implanting health by Wicresoft or interventional method.This band lobe device can implant by surgery Wicresoft or interventional method.Its principle is insertion of valve prosthesis in a collapsible metal rack in conduit.Arrive predetermined position for example Bicuspid valve or aorta by blood vessel, utilize balloon expandable to be fixed in annulus of mitral valve or aortic valvular ring place.Need not to operate on, wound is little.
This band lobe device 1 can comprise: support 2, and this support can be made by metal or synthetic material, can form netted; Valve 7, its adhere to described support 2 in, can make by biological tissue or synthetic or metal.
This band lobe device can be shrunk to the shape of tubulose or body internal channel, can send in the body by the conveyer device of prior art.For example shown in Figure 3, band lobe device is punctured into elongated shape, be transported to the intravital use of people position, for example Bicuspid valve between left atrium and the left ventricle and aortic valve position by conduit 6.Be with the lobe device to stretch out then, extend, fix position at needs from conduit 6.
For the ease of regulating its position when the charge releasing belt lobe device 1, at the connecting device that the proximal location of support 2 end of the propelling movement parts of conveyer device (promptly near) is provided with and the propelling movement parts of conveyer device are connected separably.For example shown in Figure 2, the part 5 that the propelling movement parts of conveyer device are connected with support 2 also is net form, and it combines with the part 3 of support 2 by easily fusing.
In the time will being with lobe device 1 to be discharged into application site gradually, can be by pushing the position of parts accommodation zone lobe device 1, feasible band lobe device 1 is fix in position well.By electrical heating,, thereby make band lobe device 1 separate then with pusher with part 3 fusing of easily fusing.
In addition, this connecting device also can be mechanical connecting device, for example screw connection.
The far-end of described band lobe device 1 is preferably corolla shape 4 under the natural expansion state, be attached on the heart wall so that help.
In addition, the far-end elasticity of described support is moderate, and the elasticity of the holder part at support valve place is soft, and the resilient beam of near-end.Have, the near-end of support can be designed to the supporting construction that support force is strong, the interval is big according to anatomical structure; Far-end can be designed to density height, structure that pliability is good.
This support epicoles fabric texture or synthetic material fabric (not shown).This tissue or synthetic material fabric are connected by stitching, braiding or adhesion with support, can increase adhesion and applying power with the body interior conduit simultaneously.Thereby this band lobe device has support force and adhesion, can directly be connected with the body internal channel or adhere to.
The support 2 of this band lobe device 1 is made by the metal or the synthetic material that design according to body internal channel characteristics and function, is for example made by memory alloy material, and support can be designed to self-expanding or expanded device according to anatomical structure.
Described valve 7 can be made by biological tissue or synthetic material or metal, sews up or is woven in the support.
Support, outer attached tissue or fabric are designed to avoid the composition structure of the blood supply opening of tremulous pulse, opening for example coronarius jointly.
The connecting device that is connected separably with conveyer device that band lobe device of the present utility model owing to used is positioned at mount proximal end, before this band lobe device is discharged fully, can adjust its position, after adjust fully the position, again connecting device is separated with conveyer device, thereby can guarantee good location with the lobe device.
Although at length illustrate and described this utility model with reference to exemplary embodiment of the present utility model; yet it should be appreciated by those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can carry out the various changes on form and the details, all belong to the scope of this utility model protection.
