The present invention provides for a sutureless clip with an electrode releasably attached to a spring clip electrode holder for use in placement of electrodes for heart pacemakers, the crimping tool for attaching the clips to the heart and the method of attachment. The preferred electrode holder is in the form of a spring clip formed by bending around one end of the clip to contact either the inside or outside surface of the clip. An electrode lead wire is releaseably held against the sutureless clip by the spring clip and can be removed by pulling on the wire, leaving the sutureless clip in place. A specialized crimping tool and it's method of use is disclosed for attaching the clip to the heart.

A device and method for male impotence correction and female anorgasmy. An electronic stimulator with at least one pulse generator is implanted inside the body. At least one electrode is installed in the epidural space in the sacrum section of the spinal column and a conductor running under the user's skin electrically connects the electrode to the pulse generator. The stimulator is programmable and may be controlled from outside the body. Upon command initiated by the user or the user's lover the stimulator produces very short low-voltage electrical pulses in the sacrum section that are picked up by the nerves leading to the sex organs of the user, which stimulates arousal in the user's reproductive systems. The pulses are similar to the pulses generated by heart pacemakers. In other preferred embodiments the stimulator includes one or two drug chambers and a tube extending from each chamber to a nerve for producing stimulation of a sex organ. The present invention works on both males and females. In a preferred embodiment, the programmable electronic stimulator is implanted under the skin in the patient's back. Stimulation of the nerves coming out from the parasympathetic part of the spinal cord causes dilatation of the penile arteries in the male and in the clitoris arteries of the female, which results in an erection in the male and pre-orgasmic sensation in the female. In female, the stimulation of the sacral part of the spinal cord increases sexual desire and escalation to the level of orgasm. A preferred embodiment provides for emission stimulation. Emission is stimulated by electrical excitation of the sacral part of the spinal cord by increasing the voltage of the previous impulses. The device may be preprogrammed to set in motion the emission and ejaculation process at a predetermined time interval after the start of the erection process.

The process is carried out by oriented differentiation inducing for heart pacemaker cell by embryo source multifunctional dry cell, bone marrow adhering to obtain primary culture cell, clone culturing to obtain purifying system by diluting, applying paracrine factor endothelin-1 or nervous adjusting protein-1, extracellular matrix laminated adherent protein and fiber connecting protein etc. substrate glue, trans-dyeing pacemaker gene HCN4, and in-vitro inducing embryo source multifunctional dry cell. It is various and non-immunogenicity. It can be used to treat sick sinus syndrome.

An electric stimulator for brain, heart, skin and internal organs in animals and plants where the electrodes are distributed on a supporting structure. The supporting structure may be adapted for brain, heart, skin or other internal organs, as for DBS, heart pacemaker, TENS, etc. The invention discloses a plurality of electrodes at the surface of the supporting structure, from which electrically stimulating currents can be injected into the organism. Turning off an electrode while turning on another electrode has the effect of moving the stimulation within the body of the organism from one point to another point, with the same effect but with less spent energy than physically moving the whole electrode support. We call this electrode shifting. Rotational and translational electrode shifting are possible. The invention also discloses random changes of the electrode shifting, and random changes of the stimulation time and of the stimulation duration.

The invention discloses a wireless charging and body temperature monitoring system for an implantable heart pacemaker, which realizes wireless charging of the implantable heart pacemaker through a magnetic coupling resonance wireless power transmission technology. The system carries out energy transmission by adopting the coupling of two coils, wherein the transmitting coil adopts a rounded-cornerrectangular coil structure and is placed outside the body, and the coil is wound by adopting a copper stranded wire and provided with a ferrite strip; the coil in the body is implemented by adoptinga flexible printed circuit board; and the impedance matching of the transmitting coil adopts LCC compensation topology including an inductor and two capacitors, and the receiving coil is only connected with one capacitor in series to achieve the same resonant frequency. The heart pacemaker is internally provided with an SAW (Surface Acoustic Wave) temperature detection module, and transmits temperature information outside the body by means of wireless transmission. The receiving coil of the wireless charging and body temperature monitoring system is fixed on a housing of the heart pacemaker, the thickness is thin, the number of used electronic components is small, the occupied space is small, the temperature can be checked in real time during the charging period so as to ensure the safety,and the system is applicable to implantable medical electronic equipment.

Animal models of heart failure are established, which are often used for preclinical drug efficacy evaluation and mechanism research of heart failure therapeutic drugs. The present invention provides a simple and reliable minimally invasive intervention method for establishing an animal heart failure model. By implementing the minimally invasive intervention method, the animal is installed with a cardiac pacemaker, which avoids excessive trauma to the experimental animal during the thoracotomy operation, and reduces the The complexity of pacemaker installation and postoperative care costs have greatly improved the survival rate of animals after pacemaker installation, thereby ensuring the success rate of establishing animal models of heart failure.

The invention relates to a method and a medical imaging system for acquisition of image data of the heart using a medical imaging procedure during an intervention on the heart, while the heart is stimulated by a pacing signal from an external heart pacemaker, the acquisition and/or reconstruction of the image data being controlled, in particular triggered, by the pacing signal.

A catheter, in particular for insertion of heart-pacemaker- or ICD-electrodes into a patient's body, comprises a catheter wall and a reinforcement therein for stabilization of the catheter. The reinforcement is a profile element which is adjusted to the desired mechanical properties of the catheter in the axial and peripheral direction thereof.

The invention discloses a self-synchronizing wireless heart pacemaker and a stimulating method thereof. The system is provided with a mechanical sensing detecting module, a pacemaker module, a processing module and a power supplying module, the primary function of the pacemaker is to sense and make pace of the heart of a patient, the contraction force of cardiac muscle cells of the heart can be sensed through the mechanical sensor, so that the purpose of the synchronous sensing of the beat of atrium cordis and ventricle using a pacemaker without a guiding wire is achieved to determine the cardiac cycle, the transmitting of a pace-making impulse is regulated by a pace-making regulating system according to sensed signals, and therefore the problem of the failure of making atrioventricular synchronous pace caused by atrioventricular block can be prevented.
