Abstract
Abstract The disclosure relates to a method and device for the transvenous implantation of at least one pacemaker electrode in a heart, the electrode being connected to a body of permanently magnetized or permanently magnetizable material. A magnet is utilized for moving the electrode by means of its magnetic field of force to a selected region in the heart and for causing it to radicate at the selected region of the heart.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A method of transvenously implanting at least one pacemaker electrode in a heart with said electrode electrically connectible, by means of an electric line, to said pacemaker for transferring stimulation pulses to the heart, comprising the steps of inserting the electrode which is connected to a body of material actuable by a magnetic field of force in a selected vein, applying a magnetic field of force and guiding said electrode and connected body of material to a selected region of the heart, applying and holding a permanent magnet to the body of the patient to maintain said electode and connected body of material in contact with the selected region of the heart for the period of time required for growth of body tissue which will maintain electrode positioning.
Claim 2
Independent Claim
128 words
A method of transvenously implanting at least one pacemaker electrode in a heart with said electrode electrically connectible, by means of an electric line, to said pacemaker for transferring stimulation pulses to the heart, comprising the steps of inserting the electrode which is connected to a body of material actuable by a magnetic field of force in a selected vein, applying a magnetic field of force and guiding said electrode and connected body of material to a selected region of the heart, applying and holding a permanent magnet to the body of the patient to maintain said electode and connected body of material in contact with the selected region of the heart for the period of time required for growth of body tissue which will maintain electrode positioning.
Claim 3
Dependent Claim
30 words
The method of claim 1 further including the step of removing the permanent magnet from the outside of the body of the patient after implantation of the electrode body tissue.
Claim 4
Dependent Claim
50 words
The method of claim 2 further including the steps of applying a magnetic field of force of reverse polarity and guiding said electrode and connected body of material away from said first mentioned selected region of the heart and implanting body tissue to a different selected region of the heart.
Claim 5
Dependent Claim
17 words
The method as recited in claim 1, wherein said body of material is a permanently magnetized material.
Claim 6
Dependent Claim
17 words
The method as recited in claim 1, wherein said body of material is a permanently magnetizable material.
Claim 7
Dependent Claim
20 words
The method as recited in claim 1, wherein the magnetic field of force is variable and derives from an electromagnet.
