  • Publication number: 20220323216
    Abstract: The present invention provides a delivery device for medical implants. The delivery device has a detachable structure and includes a handle (3) and a catheter assembly (1) that are separated from each other. The handle (3) and the catheter assembly (1) are connected by a transmission shaft (2). By configuring the handle (3) and the catheter assembly (1) to be separated from each other, the catheter assembly (1) has less weight than that of a traditional delivery assembly, so that the operator can position the medical implant and adjust the position of the medical implant by moving only the catheter assembly (1). The catheter assembly (1) is lighter in weight and smaller in size, which improves the stability, precision and accuracy of the operation. Moreover, the impact of vibration and/or movement of the handle (3) on the catheter assembly (1) are avoided, which further improves the stability and thus the quality of the operation.

  • Publication number: 20220054265
    Abstract: A prosthetic valve delivery catheter and device. The delivery catheter includes an outer sheath assembly and an inner sheath assembly. The outer sheath assembly includes a capsule in which a prosthetic valve can be received and an outer sheath fixedly connected at one end to the capsule. The inner sheath assembly includes an inner sheath and an anchor fixedly connected to the inner sheath. The inner sheath assembly is arranged within a lumen of the outer sheath assembly, and the capsule and the anchor form a circumferentially indexed fit therebetween. With this design, the anchor and the capsule can be driven to rotate under the action of circumferential rotation of the inner sheath, thus the matching between the prosthetic valve and a native valve annulus can be adjusted. Moreover, the capsule can be driven to move axially under actuation of the outer sheath to allow release of the prosthetic valve.

  • Publication number: 20210154007
    Abstract: A delivery device (1, 1?) for loading, delivering and deploying an implant (2) includes a handle (18), an inner tubular core (11), a sheath tube (13) and a guide tip (12). The inner tubular core (11) is coupled, at a proximal end thereof, to an inner tubular core actuation member arranged in the handle (18), and the guide tip (12) is disposed at a distal end of the inner tubular core (11) and fixedly connected to a distal end of the sheath tube (13). The sheath tube is (13) sleeved over the inner tubular core (11). Here, the proximal end of each component refers to the end thereof closer to the handle (18), while the distal end thereof is the end farther away from the handle (18). As the sheath tube (13) is fixedly connected, at the distal end thereof, to the guide tip (12), the implant (2) is loaded at the proximal end of the sheath tube (13) in the delivery device (1, 1?).

  • Patent number: 10666329
    Abstract: A method and a network system capable of enhanced transmission of data signals in a multiple-input multiple-output (MIMO) communication system using a double-layer coordinated beamforming are disclosed. A first layer precoding matrix is obtained from long-term channel state information between user equipment and network equipment, and a second layer precoding matrix obtained from the first layer precoding matrix and from real-time channel state information between the user equipment and the network equipment. The real-time channel state information for the second layer precoding matrix determination includes a predetermined signal-to-interference-plus-noise ratio (SINR), and/or a predetermined power value associated with a single antenna of the user equipment, which are used as optimization parameters. The first and second layer precoding matrices are combined for the double-layer coordinated beamforming.

  • Publication number: 20170180021
    Abstract: Some embodiments relate to a method for transmitting a signal carrying data in a multiple-input multiple-output communication system. The method comprises applying a double-layer coordinated beamforming. The method also comprises receiving a first layer precoding matrix obtained at least from long-term channel state information between user equipment and network equipment, determining a second layer precoding matrix obtained from the first layer precoding matrix and from real-time channel state information between the user equipment and the network equipment, and obtaining the double-layer coordinated beamforming by combining the first layer precoding matrix and the second layer precoding matrix. Determination of the second layer precoding matrix is optimized by using a predetermined signal-to-interference-plus-noise ratio of the signal, and/or a predetermined power value associated with a single antenna of the user equipment, as optimization parameters.
