  • Patent number: 10925715
    Abstract: A method of providing support for an organ in the body of a patient comprises providing a support element with a first portion coupled to a first anchor and a second portion coupled to a second anchor through an aperture. The support element has a central portion between the first and second portions comprising a ribbon-like filamentary element. The first anchor is attached to a first tissue portion at a first location lateral to the organ. The second anchor is attached to a second tissue portion at a second location lateral to the organ. Tension of the central portion between the first and second anchors is adjusted by moving the second portion through the aperture in the second anchor so that the central portion of the support element provides a sling-like support for the organ.

  • Patent number: 10912549
    Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.

  • Patent number: 10893926
    Abstract: Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure attached to the filtering membrane which retains the filtering membrane in position across the ostium of the left atrial appendage by permanently engaging a portion of the interior wall of the left atrial appendage. The support structure may be radially expandable from a first configuration to a second configuration which engages the ostium or the interior wall of the left atrial appendage. The filtering membrane may define an opening therethrough that is configured to expand from a first size which inhibits the passage of thrombus therethrough to a second size which allows an interventional device, e.g.

  • Patent number: 10835378
    Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve/holder subassembly.

  • Patent number: 10813697
    Abstract: Methods of removing tissue from a patient during a surgical procedure, such as for preparing a spine of a patient to receive an implant during a fusion procedure. A working portion of an instrument is moved with actuators relative to a hand-held portion in at least three degrees of freedom including pivoting in pitch and yaw about a pivot. The working portion is translated while the hand-held portion is manually grasped and moved during the surgical procedure. The working portion is rotated with a drive mechanism to remove a volume of the tissue of the patient with a cutting accessory of the working portion. The actuators may move the working portion to substantially maintain the cutting accessory in a desired relationship to a virtual boundary defining the volume of the tissue to be removed. A position of the cutting accessory relative to the virtual boundary may be determined and tracked.

  • Patent number: 10729527
    Abstract: A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.

  • Patent number: 10709436
    Abstract: A method for securing soft tissue to bone which does not require the surgeon to tie suture knots to secure the tissue to the bone. Suture is passed through the graft at desired points. A cannulated plug or screw is pre-loaded onto the distal end of a driver provided with an eyelet implant at its distal end. Suture attached to the graft is passed through the eyelet of the implant located at the distal end of the driver. The distal end of the driver together with the eyelet implant is inserted into the bone. Tension is applied to the suture to position the graft at the desired location relative to the bone. The screw or plug is advanced into the pilot hole by turning the interference screw or tapping the plug until the cannulated screw or plug securely engages and locks in the eyelet implant, so that the cannulated plug or screw with the engaged eyelet implant is flush with the bone.

  • Patent number: 10702276
    Abstract: Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.
