  • Patent number: 11737898
    Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

  • Publication number: 20220354645
    Abstract: The disclosure relates to transcatheter stented prosthesis delivery devices including a handle assembly connected to a shaft assembly on which a stented prosthesis is loaded and compressively retained with a plurality of elongate tension members. The delivery devices include a cutting assembly that can sever the elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient. Certain embodiments position the cutting assembly at least within the shaft assembly and others position the cutting assembly over the shaft assembly. Various disclosed cutting assemblies are actuated with the handle assembly or the like, which draw the tension members across the blade or vice versa.

  • Publication number: 20200375770

The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

  • Publication number: 20050136931
    Abstract: A method and system for management of radio frequency coverage over a wide geographic area. A database is created specifying a geographic location for each of a large number of possible communication locations within a wide geographic area. Selected physical parameters are then associated with each communication location including: addresses; site plans; structural drawings; and, actual measured signal strength for multiple entities authorized to transmit at selected frequencies within that geographic area. Thereafter, communication locations may be automatically accessed by specifying either a physical location or by accessing those locations where measured signal strengths fall below a selected level. Once accessed, all stored physical parameters associated with a selected communication location may be displayed, including: photographs of the location, site plans, structural drawings and readiness data.
