Abstract: The present invention relates to a magnetic navigation-guided tear-away sheath for cardiac conduction bundle pacing, including a sheath body and a joint fixedly connected to a rear end of the sheath body. The sheath body includes a front flexible section and a rear fixed section, and the front flexible section is freely bendable. An outer surface near a head end of the front flexible section is provided with a plurality of pairs of half-ring magnets, two half-ring magnets in each pair of half-ring magnets are symmetrically disposed and form a ring, and a gap is kept between the two half-ring magnets. The head end of the front flexible section is provided with three electrodes uniformly disposed in a circumferential direction, and the three electrodes can be freely combined two by two, to form three electrode pairs used to record and position an intracardiac potential.

Abstract: Provided is a wire fixing device for a cardiac pacemaker electrodes, including: an electrode fixator having an electrode clamping component, first hooks and second hooks; the electrode clamping component includes a first clamping piece and a second clamping piece that are semicircular cylindrical, the first clamping piece and the second clamping piece are connected by a clamp hinge connector, and a circular tube is formed when the electrode clamping component is closed; first hooks are provided on the back of the first clamping piece, second hooks are provided on the back of the second clamping piece, and hook tips of the first and second hooks are all bent towards a rotation direction of the electrode clamping component during closing; and the first and second hooks can be interlaced with each other when the electrode clamping component is closed, and can be separated when the electrode clamping component is open.

Abstract: A deformable high-density and precision balloon cardiac mapping catheter includes a catheter, an electrode head mounted at one end of the catheter, and a handle mounted at the other end of the catheter. A head electrode pair, a middle expansion body and a rear expansion body are sequentially disposed on the electrode head from left to right. A liquid storage apparatus is disposed on a surface of the handle. The liquid storage apparatus includes a reservoir tube. A liquid outlet is disposed at one end of the reservoir tube.
