An annular mapping catheter includes a catheter body. The catheter body has a distal end and a proximal end. The distal end of the catheter body is provided with a distal end assembly, and the proximal end of the catheter body is provided with a handle. The distal end assembly is made of a head end catheter that has a shape memory function. The distal end assembly in a free state presents a predetermined bent shape including an annular part and a vertical part. The vertical part connects the annular part to the catheter body. The distal end assembly is provided with an electrode. The annular mapping catheter can detect an electrocardiogram activity near a pulmonary vein ostium and can better locate a cryoballoon in the heart.

A pericardium puncture needle assembly comprises a puncture needle () and a guide wire () capable of sliding in the puncture needle (); or comprises an outer sleeve () and a guide wire () capable of sliding in the outer sleeve (); or comprises an outer sleeve () and a puncture needle () and a guide wire () capable of sliding in the outer sleeve (), wherein after the puncture needle () is pulled out of the outer sleeve (), the guide wire () is capable of sliding in the outer sleeve (). The guide wire () is made of a highly elastic material and comprises a far-end bent segment (). The far-end bent segment () is formed by bending the guide wire () and has a preset bending shape, and is suitable for being recovered from a stretching state to the preset bending shape. The tip of the far-end bent segment has a pointed structure. The pointed structure has a far end and a near end, the far-end has a pointed end for puncturing, and the pointed end rotates by an angle of at least 90 degrees relative to the near end of the pointed structure on a length not more than 3 mm of the pointed structure. The puncturing direction of the guide wire () falls in a plane defined by a normal direction of a needle point plane of the puncture needle () or the outer sleeve () and an axial line of the puncture needle () or the outer sleeve (). When the pericardium puncture needle assembly is used for puncturing pericardium, the degree of twisting freedom of the guide wire () can be limited to some extent.

Disclosed is a pericardiocentesis needle component (), comprising a guide wire () and a puncture needle (). The guide wire () extends into and through the puncture needle (), and the guide wire () comprises a bent section () at the distal end and a straight section at the proximal end. The bent section () at the distal end is formed by bending the guide wire (), and the end of the bent section is a pointed-shape structure. The guide wire () is made of a highly elastic material. The pointed end rotates at least 90 degrees within a range of no more than 3 mm starting from the pointed end at the bent section () of the guide wire. The pericardiocentesis needle component () of the present invention is less likely to damage a heart during a pericardiocentesis procedure.

It is provided a renewable energy base station, which is used in a wireless cellular system, including: an adjustment request determining part for determining whether an adjustment to a coverage area is required; an adjustment request transceiver in case where it is determined that the adjustment to the coverage area is required, sending a coverage area adjustment request to neighboring base stations in the wireless cellular system, and receiving an adjustment request response from the neighboring base stations; an adjustment request responding part for determining whether the coverage area adjustment request from the one of the neighboring base stations is allowed in case where receiving the coverage area adjustment request from one of the neighboring base stations; and a response transmitter for sending the adjustment request response to the neighboring base stations based on a result of the determination made by the adjustment request responding part.

Renewable energy base station and coverage adjustment method therefor, and wireless cellular system

Disclosed are a communication control device, a communication control method and the system thereof, which provide efficient multi-base station joint services in a mobile communication system using dynamic clustering. Optimal base station clustering is chosen according to the communication state between a terminal and each base station. The communication control device connects with multiple base stations through a network, and clusters the multiple base stations dynamically so that the clustered multiple base stations can provide services for the mobile terminal in union. The communication control device comprises: an interface, connecting with multiple base stations, receiving channel state information related to the mobile terminal from each base station; a memory unit, storing the channel state information of the mobile terminal received from the interface; a control unit, clustering each base station dynamically according to the channel state information of the mobile terminal stored in the memory unit.
