  • Patent number: 10952837
    Abstract: A medical device including a mesh prosthesis having a first layer having an opening a second layer secured to the first layer and forming a pocket therebetween. A deployment device is positioned in the pocket and arranged to resiliently exert a deployment force on the mesh prosthesis to urge the mesh prosthesis into a deployment shape. The deployment device has a first shape when deployed that has at least one dimension larger than that of the opening to frustrate removal of the deployment device therethrough. Upon application of a suitable pulling force the deployment device is reconfigurable into a second shape that permits the deployment device to be removed from the pocket through the opening upon application of the suitable pulling force. A method of using a medical device is also included.

  • Patent number: 10946125
    Abstract: An apparatus, system, and method for treating an incisional wound having incisional walls. The apparatus includes a conduit having a first end for receiving reduced pressure and a second end. The apparatus further includes a scaffold. The scaffold has opposing surfaces for positioning adjacent the incisional walls and is fluidly coupled to the second end of the conduit for receiving the reduced pressure. The scaffold is generally elongated in shape and has a thickness between the opposing surfaces that is sufficiently thin for positioning within the incisional wound. The apparatus further includes an internal manifold that has a primary flow channel extending generally longitudinally within the scaffold and between the opposing surfaces of the scaffold. The internal manifold is fluidly coupled to the second end of the conduit. The application of the reduced pressure through the scaffold and the internal manifold induces tissue apposition between the incisional walls.

  • Patent number: 10925707
    Abstract: A blood filter device having occlusion-resistant characteristics. The occlusion-resistant characteristics decrease the likelihood of the filter being blocked by thrombi. The filter device includes at least one anchor portion for anchoring the filter device within one or more arteries, and a filter portion for filtering thrombi from the blood entering the artery. In some embodiments, an anchor portion is capped with a filter cap. In various embodiments, the filter cap is protrudes into the aorta to promote occlusion resistance. In one embodiment, the device can be modified in situ to re-establish normal blood flow through the artery in the unlikely case of thrombotic or other blockage of the filter. In some embodiments, a bypass opening or open channel defining an access port is provided to accommodate passage of surgical instruments into the artery and to enable blood flow to bypass the filter should the filter become heavily occluded.

  • Patent number: 10898328
    Abstract: Devices and methods provide enhanced treatment of a cardiac valve annulus. Methods generally involve contacting an anchor delivery device with the valve annulus and releasing a plurality of coupled anchors from the anchor delivery device to secure the anchors to the-annulus. Anchors, which in some embodiments are super-clastic or shape memory self-securing anchors, are then drawn together to tighten the annulus. Devices generally include an elongate catheter having a housing at or near the distal end for releasably housing a plurality of coupled anchors. The housing may be flexible, may conform to a valve annulus, and in some embodiments may be coupled with an expandable member to enhance contact of the housing with annular tissue. In one embodiment, self-securing anchors lie approximately flat with the delivery device housing, allowing anchors with relatively large deployed shapes to be housed in and deployed from a relatively narrow delivery device.

  • Patent number: 10881390
    Abstract: A cord that has been previously affixed around an annulus can be fastened using a sliding member that locks into a housing. Before those two parts are locked together, the cord is free to slide through a channel in the sliding member, and a shear pin prevents the sliding member from moving. After those two parts are locked together, portions of the cord are squeezed between the upper surface of the sliding member and one wall of the housing, and other portions of the cord are squeezed between the lower surface of the sliding member and another wall of the housing, so that the cord can no longer slide. After locking, a sliding cutting element can be actuated to cut off portions of the cord that are proximal with respect to the two locked parts.
