Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0026] refer to figure 1 and figure 2 , according to an embodiment of the present invention, a wireless communication system based on a vascular stent includes an in-vivo communication device 1001 and an in-vitro communication device 1002 , both of which communicate wirelessly through the vascular stent as an antenna of the in-vivo communication device 1001 .

[0027] The in-body communication device 1001 includes a trigger circuit 2001 and a vascular stent 2004. Those skilled in the art will understand that the vascular stent 2004 is used as a metal structural material (such as figure 2 The cylindrical mesh structure shown) can be used to transmit and receive wireless signals of a certain frequency band that match its shape and size. The frequency...

Abstract

The invention discloses an in-vivo wireless communication device based on a vascular stent and a wireless communication system. The in-vivo wireless communication device comprises the vascular stent and a trigger circuit mounted on the vascular stent, the trigger circuit is used for acquiring health condition data related to vascular diseases and / or providing in-vivo therapy related to the vascular diseases, an output of the trigger circuit is fed to the vascular stent, the vascular stent serves as an antenna to transmit wireless signals outwards, and the vascular stent further serves as the antenna to receive wireless signals in vitro and transmit the wireless signals to the trigger circuit. A special antenna structure does not need to be arranged in a blood vessel, the in-vivo wireless communication device is small in size, and the blood vessel can be monitored and treated in real time at low cost.

Description

technical field [0001] The invention relates to an in vivo wireless communication device and a wireless communication system based on a blood vessel stent. Background technique [0002] Vascular stent refers to the stent that is implanted at the lesion position on the basis of lumen balloon expansion to achieve the purpose of supporting the stenotic occlusion segment of the vessel, reducing the elastic retraction and remodeling of the vessel, and maintaining the smooth blood flow in the lumen. Structure, mainly divided into coronary artery stents, cerebrovascular stents, renal artery stents, aortic stents, etc. Materials commonly used to make stents include metal tantalum, medical stainless steel, nickel-titanium alloy, etc. [0003] As of 2013, the number of patients with cardiovascular disease in my country has reached 250 million, and the number of patients who die of cardiovascular disease every year reaches 3 million. Among cardiovascular diseases, the morbidity and m...
