  • Publication number: 20210161665
    Abstract: An annuloplasty ring for attachment to an annulus of a tricuspid valve comprises an elongate tube of suturable material comprising a central segment and first and second end segments. An arcuate stiffener is received in the central segment of the tube and extends the length thereof. The arcuate stiffener is circumferentially confined within the central segment to prevent circumferential movement of the stiffener relative to the tube. The first and second end segments of the tube lack a stiffener and are axially deformable.

  • Patent number: 10226343
    Abstract: An annuloplasty ring holder including a head having an upper surface and an annuloplasty ring receiving surface facing opposite the upper surface. The annuloplasty ring holder also includes means for attaching an annuloplasty ring to the annuloplasty ring receiving surface. The means for attaching an annuloplasty ring to the annuloplasty ring receiving surface may include one or more suture guides operatively associated with the head and configured to position one or more sutures to removably associate an annuloplasty ring with the annuloplasty ring receiving surface. The head may include a central hub and more than one spoke radiating out from the central hub. If the head is thus configured, each spoke will include a portion of the annuloplasty ring receiving surface.

  • Patent number: 8361093
    Abstract: A band forming apparatus for banding an internal body part and method of using same. The band forming apparatus is initially supplied as a relatively straight structure so that it can be, for example, inserted through a catheter or narrow incision such as when using endoscopic or robotic surgery techniques. Alternatively, the band forming apparatus may be used or inserted using conventional surgical techniques. In use, the initially straight assembly can be formed into a loop or band around an internal body part. Embodiments of the band forming apparatus include a compressible tube having first and second tube ends and an orifice in the tube wall between the first and second tube ends. A string is received in the tube, the string having a first end extending out of the first end of the tube and a second end extending out of the orifice. Alternatively the second string end may extend out of the second tube end.

  • Patent number: 8048255
    Abstract: An implantable annuloplasty suture guide is intended to lie against at least a portion of an annulus surrounding a human heart. The implantable annuloplasty suture guide is made of an elongated ribbon of braided, heat setable material. The braided, heat-setable material is heat-set in a curved lengthwise configuration corresponding to at least a portion of the annulus of the human heart valve. A method of making an implantable annuloplasty suture guide configured to lie against at least a portion of an annulus defined by tissue surrounding a human heart. The method includes the steps of providing an elongate biocompatible ribbon comprising a braided, heat setable material. A fixture is provided, with the fixture comprising a heat conducting material defining an elongate cavity having a curved length-wise configuration corresponding to at least a portion of the annulus defined by the tissue surrounding the human heart.

  • Publication number: 20110071626
    Abstract: A device for the treatment of ischemic mitral regurgitation of a damaged left ventricle having an opposing papillary muscles displaced laterally or axially relative to the mitral annulus. The device includes a lateral limb configured to extend between opposing papillary muscles of a left ventricle and first and second axial limbs extending from spaced points on the lateral limb to form an essentially U-shaped configuration. The first and second axial limbs are configured to extend between the lateral limb and a mitral annulus. A method for the treatment of mitral regurgitation comprises extending a first segment of the lateral limb of the device across opposing sides of a ventricle near opposing papillary muscles. The segment of the first lateral limb is shortened as needed to put the first and second papillary muscles into a substantially normal lateral position relative to the mitral annulus and the length of the segment of the first lateral limbs is fixed.

  • Patent number: 7758491
    Abstract: An apparatus implantable in a heart ventricle includes a frame configured to engage an inner circumferential periphery of the ventricle and to expand and contract between an expanded state corresponding to a desired end diastolic diameter of the ventricle and a contracted state corresponding to a desired end systolic diameter of the ventricle. A bistable structure is operatively associated with the frame. The bistable structure mechanically assists movement of the ventricle toward both an end systolic diameter during systole and an end diastolic diameter during diastole. The bistable structure may be integrally formed of the frame. A method of implanting the apparatus in a heart ventricle includes surgically accessing a ventricle, inserting the apparatus in the ventricle and attaching the device to a portion of myocardium defining an inner circumferential periphery of the ventricle.
