Abstract

The invention discloses a wireless atrial pacing device implanted through a catheter. The device comprises a waist part provided with a left disk, a right disk and two disks on the two sides, wherein the disks are in bowl shapes, the waist part is cylindrical, the diameter of each disk is larger than that of the waist part, and a wireless pacemaker host is implanted in the waist part; the left disk, the right disk and the cylindrical support waist part are braided and connected into a whole through nitinol. Through the device, physiological atrial pacing on the basis of the wireless technology is realized, the disks enable the pacemaker to be fixed to the interatrial septum of the atrium more firmly, and an electrode is more closely attached to the interatrial septum tissue; the net-shaped cylindrical support waist part is formed by braiding nitinol wires, the two sides of the support are provided with the left disk and the right disk, the wireless pacemaker host is implanted in the cylindrical support waist part, and containing space and supporting are provided for the pacemaker host; the electrode at the head end of the wireless pacemaker host stretches towards the two side disks, the tail end of the electrode is connected with four metal electrodes located on the inner sides of the disks, and the electrode is in contact with the interatrial septum tissue, so that atrial pacing is realized.

Description

technical field

[0001] The invention belongs to the technical field of pacemakers, in particular to a wireless atrial pacemaker implanted through a catheter. Background technique

[0002] At present, the most ideal treatment method for patients with sick sinus syndrome is to implant a cardiac pacemaker. Reflux, infection of the pocket where the pulse generator is placed, hematoma, etc. The existing pacemaker system comprises two major parts, a pulse generator and a pacing electrode lead. The main complications of pacemakers come from these two parts, including pocket infection and pocket hematoma at the implanted pulse generator site, surgical scars that affect the appearance, lead dislocation, lead breakage, and venous thrombosis in the lead path. , tricuspid regurgitation; pneumothorax may also occur during implantation.

[0003] At present, the existing wireless pacemaker refers to a ventricular pacing device implanted in the ventricle of the heart. Ventricular pacing ...
