  • Publication number: 20250204915
    Abstract: A process for adding compliance to a blood vessel preferably includes forming a first puncture through a first wall segment of the blood vessel, forming a second puncture through a second wall segment of the blood vessel at a diametrically opposed location, deploying a first tissue anchor on an outside of the blood vessel in an area of the first puncture, deploying a second tissue anchor on the outside of the blood vessel in an area of the second puncture, and tensioning an elastic band coupled to the first tissue anchor and the second tissue anchor, thereby causing the elastic band to reshape the target segment of the blood vessel to a non-circular cross-sectional shape. The elastic band elongates and contracts during cardiac cycles for adding compliance to the blood vessel.

  • Publication number: 20220039954
    Abstract: A heart valve repair system includes an implantable device and a connector. The implantable device is configured to attach to at least two leaflets of a native heart valve of a patient and hold the at least two leaflets in a relatively fixed position. The connector is separate from the implantable device and includes first and second tissue anchors. The connector is configured to be attached to the at least two leaflets of the native valve when the at least two leaflets are held by the implantable device in the relatively fixed position. The implantable device is configured to be detached from the at least two leaflets and removed from the patient with the connector remaining attached to the at least two leaflets.

  • Publication number: 20220008233
    Abstract: Described herein are artificial valves that have a frame and leaflets that grow or expand with a patient. Upon placing the valve inside the patient, the valve expands as the annulus of the patient expands. The frame of the valve is configured to expand which in turn causes the leaflets to expand (e.g., to grow). The valve includes a thin undulating wire embedded inside the leaflets. As the annulus of the patient grows, the frame expands, and as the frame expands, the leaflets grow. The growth or expansion of the leaflets is configured so that the valve continues to operate properly (e.g., the leaflets continue to coapt) with expansion of the annulus. The change in size of the valve can be configured to accommodate changes in size of the annulus from an infant or child to an adult.

  • Patent number: 11188986
    Abstract: Rooms, structures, vehicles, and other objects can be accurately diagrammed, often without performing a physical on-site inspection. Photographs of a room, structure, vehicle, or other object are uploaded to a computer having a processor. A base calibration measure is determined for a room, structure, vehicle, object, or component thereof, depicted in the photographs using at least one known dimension for items observable in the photographs. The base calibration measure is then used to determine dimensions of other areas, items, or objects depicted in such photographs, and to create at least one scale diagram of the subject matter of the photographs. Damages areas of the structure/vehicle/object can be assessed from the scale diagram. The scale diagram can then be used to calculate appropriate insurance payment amounts for damage claims.
