摘要： The present disclosure discloses a guide tube assembly for transcatheter treatment system, a treatment system and a method. The guide tube assembly for transcatheter treatment system has opposing distal and proximal ends. The distal section of the guide tube assembly has a curved extension including a first curved section, which is configured to have a bend angle by pre-shaping and/or bending, and a second curved section, which is located at a distal end of the first curved section and configured to have a bend angle by bending. The first curved section and the second curved section are located in different planes and provided by one or two tubes respectively which are movably inserted one in the other. The guide tube assembly is more suitable for interventional operations in complex physiological structures.

摘要： The present disclosure discloses an interventional injection device and an interventional injection system. The interventional injection device includes an operating handle, a sheath and an injection member. The operating handle includes a housing and a driving assembly. The driving assembly includes a driving knob that is rotatably connected to the housing and a driving rod that is movably inserted into the housing and threaded to the driving knob. A proximal end of the sheath is fixedly connected to the housing. The injection member is movably inserted in the sheath. The injection member includes a first channel and an injection needle connected to a distal end of the first channel in a tight seal, and a proximal end of the injection member is fixedly connected to the driving rod. The driving rod is configured to move axially by rotation of the driving knob relative to the housing so as to drive the injection member to move and thus drive the injection needle to penetrate into a target tissue region. Since the driving rod and the driving knob are threaded to each other, the rotational motion is converted into a linear motion for advancing the injection needle. The driving knob is rotated so that the advance speed of the needle can be controlled more accurately and stably.

摘要： A sleeve (10), an injection device (200), an injection system (300), an ablation device (600), and an ablation system (700). The sleeve (10) includes a main body (11), the main body (11) defines a first channel (12) passing through the main body (11) in an axial direction, and a side wall of the main body (11) defines at least one second channel (13) which is communicated with the first channel (12). When the sleeve (10) abuts against the ventricular tissue wall, the fluid can only flow out from the second channel (13) in the side wall of the sleeve (10), which means that the needle can be advanced for treatment of the ventricular tissue.

摘要： The present disclosure discloses an adaptive guiding device and a transcatheter treatment system. The adaptive guiding device includes a hollow flexible catheter, which is pre-shaped and has a bend in a natural state. The distal part of the flexible catheter includes a distal section, the distal section includes a transition segment and a straight segment, the transition segment is bendable so as to change an orientation of the straight segment, and a bending force application point is adjacent to a connection of the transition segment with the straight segment. In the adaptive guiding device and the transcatheter treatment system provided by the present disclosure, the adaptability of the guiding device to blood vessels with complex anatomical shapes such as the aortic arch is improved, the structure of the guiding device is simplified, and the operation safety of the device is improved. There is no need for a large avoidance space in use of the guiding device, and the tissue can be prevented from extending into the avoidance area, so that the guiding device has a larger operation and adjustment space and a more convenient initial position for adjustment.
