  • Publication number: 20220211500
    Abstract: Systems and methods for remodeling of tissue, such as heart tissue. In some configurations, the systems and methods are directed toward remodeling of the mitral valve of a patient. The systems and methods can include a first tissue anchor, a second tissue anchor, a suture that extends between the tissue anchors, and a suture lock that secures the suture relative to at least one of the tissue anchors or fixes a length of the suture. The systems and methods can also include a suture trimmer that can trim an excess portion of the suture. In some configurations, the suture lock is reversible to allow for iterative adjustments of the remodeling. In some configurations, the tissue anchors include a feature or features, such as one or more barbs, to inhibit removal of the tissue anchor from an implanted position within tissue.

  • Patent number: 11369384
    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.

  • Patent number: 10149700
    Abstract: Systems and methods for non-serial, substantially simultaneous or simultaneous tissue sampling and placement of multiple markers/fiducials in a non-linear, distributed or three dimensional configuration. The systems and methods can be applicable to other forms and combinations of distributed/3 dimensional/spherical localization which may include a single procedure or combination of procedures that may include 3D biopsy, fiducial placement, brachytherapy seed placement, injection/infusion of bioactive materials (e.g., chemotherapy, small molecules, cellular materials, cells, caustic materials, proteolytics, embolic material, glue, etc.), thermally or electrically derived ablation.

  • Patent number: 9617055
    Abstract: A consumer package is disclosed that can be opened with one hand. The packaging can have a finger or thumb loop attached to a panel that allows a user to use a finger of the same hand holding the package to open the package. The finger or thumb loop can be designed to have strength and structural integrity to open the package rather than just to hold the package. The package can have a finger or thumb grip portion attached to the panel to open the package. The package can have a finger or thumb hold attached to the panel to open the package.
