Balloon dilation patch electrode system

Abstract

The invention relates to the technical field of medical instruments, in particular to a balloon dilation patch electrode system. The balloon dilation patch electrode system comprises a dilation cannula, localizing electrodes, a signal conversion adapter, a balloon and a catheter, wherein the dilation cannula is made of an elastic material, and a catch groove axially penetrating through the whole dilation cannula is formed in the side wall of the dilation cannula; the number of the localizing electrodes is at least two, and all the localizing electrodes are attached to the outer wall of the dilation cannula at intervals in the axial direction of the dilation cannula, are insulated from each other and are connected with the signal conversion adapter through electrode connecting wires; the balloon is arranged at the front end of the catheter, the balloon is inserted into the dilation cannula, and the tail end of the catheter is connected with a catheter adapter. The balloon dilation patch electrode system of the patent can be implanted into a body together with a pacing electrode, the position of the pacing electrode is displayed through a three-dimensional electroanatomical mapping system, and when the pacing electrode reaches a specified pacing target spot, the balloon dilation patch electrode system can be easily separated from the pacing electrode and is withdrawn from the body, and accordingly, X-ray development can be replaced, the success rate and safety are improved, and radiation damage of rays is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon expansion patch electrode system. Background technique [0002] Pacemaker electrode implantation requires the implantation and fixation of pacing electrodes (such as atrial electrodes, ventricular electrodes) at designated pacing targets under the guidance of medical imaging equipment. At present, the implantation of pacing electrodes is carried out under X-ray irradiation. Pacing electrodes are implanted according to the anatomical parts shown by X-rays. Most of them are implanted in the apex and outflow tract. Traditional pacing has many disadvantages, including remote The incidence of heart failure and atrial fibrillation increases in the early stage, and left bundle branch pacing and HIS pacing are currently the best pacing sites. Most look for HIS and left bundle branch based on anatomical location. Therefore, left bundle branch pacing and HIS pacing also...

AI Technical Summary

Problems solved by technology

Therefore, left bundle branch pacing and HIS pacing also need to be operated under X-ray fluoroscopy, and the exposure time is longer than traditional surgery

Three-dimensional electroanatomical mapping can accurately determine the anatomical position of HIS, but the pacing electrode cannot be visualized in the three-dimensional electroanatomical mapping system
