Abstract
Abstract An occluder supporter (1) is installed to the valve of a mammalian heart for preventing valve reflux by stitching attachments (5) to the edges of the occluder. At least one bridging piece (7) spaces the attachments (5) to maintain the edges of the occluder in a mutually close position. The bridging piece(s) are provided between the attachments in such a way as to traverse the valve aperture. A pair of end bridging pieces (7 as shown) or a central bridging piece (7 Figure 4) may be provided. In further embodiments three bridging pieces (27 Figure 3) radiate from a central point to respective attachments (25) or form a triangular structure (32 Figure 9) with attachments (25) at the apices. <IMAGE>

Claim 3
Dependent Claim
104 words
An occluder supporter which is provided to the atrial side of the ventricle valve of a mammalian heart in order to prevent the occurrence of valve reflux, the characterising feature of said occluder supporter being the provision of a pair of stitched attachments which are sewn onto the contralateral sides of the occluder and with a support which is provided between the said stitched attachments in such a way as to traverse the valve aperture, said support supporting and maintaining said contralateral edges in a mutually close position, and said support bending in such a way as to protrude out on the atrial side.
Claim 4
Dependent Claim
104 words
An occluder supporter which is provided to the atrial side of the ventricle valve of a mammalian heart in order to prevent the occurrence of valve reflux, the characterising feature of said occluder supporter being the provision of a pair of stitched attachments which are sewn onto the contralateral sides of the occluder and with a support which is provided between the said stitched attachments in such a way as to traverse the valve aperture, said support supporting and maintaining said contralateral edges in a mutually close position, and said support bending in such a way as to protrude out on the atrial side.
Claim 5
Dependent Claim
88 words
An occluder supporter which is provided to the aortic side of the aortic valve of a mammalian heart in order to prevent the occurrence of valve reflux, the characterising feature of said occluder supporter being the provision of at least 3 stitched attachments which are sewn onto each connecting portion of the occluder, and with a support which is provided between the said stitched attachments in such a way as to traverse the valve aperture, said support supporting and maintaining each connecting portion in a mutually close position.
Claim 6
Dependent Claim
88 words
An occluder supporter which is provided to the aortic side of the aortic valve of a mammalian heart in order to prevent the occurrence of valve reflux, the characterising feature of said occluder supporter being the provision of at least 3 stitched attachments which are sewn onto each connecting portion of the occluder, and with a support which is provided between the said stitched attachments in such a way as to traverse the valve aperture, said support supporting and maintaining each connecting portion in a mutually close position.
