  • Publication number: 20190343632
    Abstract: An apparatus for augmenting the length of native chordae tendineae to restore physiological leaflet coaptation. The apparatus includes a delivery device having a lumen therein which at least partially houses a prosthetic cord. The prosthetic cord has a first end with a first clasp configured to attach to a native chordae tendineae and a second end with a second clasp configured to attach to the native chordae tendineae. The native chordae tendineae is severed between the first clasp and the second clasp, and the length of the prosthetic cord between the first clasp and the second clasp is adjusted until physiological leaflet coaptation is restored.

  • Publication number: 20190343633
    Abstract: Disclosed herein are various embodiments of suture adjustment mechanisms for anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.

  • Publication number: 20190343634
    Abstract: Disclosed herein are various embodiments of anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Each of the disclosed anchor embodiments transitions from a first position for delivery of the anchor to the heart wall to a second position for insertion of the anchor into the heart wall. In some embodiments, it is the transition to the second position that provides the necessary insertion force for inserting the anchor into the heart muscle sufficient to retain the anchor from accidental withdrawal from the heart wall during normal valve operation (e.g., when a valve leaflet pulls on the suture attached to the anchor during systole). Such anchors are particularly suitable for use in intravascular, transcatheter procedures as described above given the inherent difficulties in providing sufficient force for insertion of an anchor into the heart wall with a flexible catheter.

  • Publication number: 20190343635
    Abstract: A method of making an intraluminal device having an implanted configuration and a modified configuration following the implanted configuration. The method includes preparing the implanted configuration of the intraluminal device by forming a support scaffold, creating a patch, and coupling the patch to the support scaffold. The support scaffold can include a lumen defined by a luminal surface. The patch can be coupled to the support scaffold along a length of the luminal surface such that the patch covers less than a full circumference of the luminal surface along the length. The patch is designed to be removed from the support scaffold following implantation of the intraluminal device to transition the intraluminal device from the implanted configuration to the modified configuration.

    Abstract: A multi-component implant insertion system for insertion of an intervertebral implant cage and methods of use thereof are described herein. Preferably, the proximal end of a hollow jaw is inserted into the distal end of an inserter. Once inside the inserter, a thread on the jaw engages a corresponding thread inside the inserter, allowing axial advancement of the jaw along the inserter. A ram is inserted through the proximal end of the jaw until the distal end of the ram protrudes at the distal end of the inserter assembly. Optionally, an adjustable stop introduced onto the superior portion of the inserter allows for control over the depth of insertion of the implant. An implant of appropriate size is introduced to the jaw of the inserter assembly and the implant/inserter assembly can be impacted into the vertebral body until the adjustable stop contacts the anterior edge of the vertebral body.

    Abstract: A core muscle strengthening suit for scoliosis is described. The suit uses pieces of material constructed and assembled to transfer force generated by the wearer while walking to rotate the wearer's trunk in the direction of an existing axial twist to exercise and strengthen countervailing muscles in an attempt to maintain a normal gait. The resulting stronger rotational muscles persist in pulling the wearer's spine into alignment when the suit is removed.

    Abstract: A noninvasive, brain cooling method and device for cerebral cooling via a patient's nasopharyngeal cavity, is described. Thermal conductive nasal prongs are inserted into a nasal cavity and are cooled by thermoelectric cooling elements. An outward air driving fan inside the device drives a cold air current through the nasal and oral cavities. Heat transfer between the cold air and the surface of the nasal cavity cools the nasal cavity, which in turn, cools a patient's brain. Real-time temperature sensing data provides feedback for closed-loop cooling control.
