Abstract
The present invention relates to an assembly for replacing a heart valve or to a coronary angioplasty assembly, comprising an introduction sheath (13) for an introducer (1) or for a delivery catheter (1′), which is smaller compared to an introducer, intended to be introduced into an artery of a human body. The invention basically comprises: either integrating the metal support of an electrode of the cardiac stimulator into a part to be fitted around the introduction sheath that is introduced into the artery of a patient or into a guide wire that becomes a bipolar electrode support; or connecting the cathode of an external cardiac stimulator to the guide wire of an artificial valve and the anode to a transcutaneous electrode in contact with the skin of the patient.
Claims18
An assembly for replacing a heart valve by the percutaneous route, comprising:
- a device forming an introducer comprising at least one tubular introduction sheath, intended to be introduced into an artery of a human body (C) and to allow through a surgical intervention device;
- a sleeve adapted to be fitted around the introduction sheath, the sleeve being made of electrically conductive material on at least one part of the outer periphery thereof so that, when the sheath is introduced into the artery of a human body with the sleeve fitted around the sheath, the conductive periphery of the sleeve is in contact with the subcutaneous tissue of the body or with the artery, the sleeve further comprising an electrical connection to an electrode of a cardiac stimulator outside the body;
- at least one guide wire intended to be introduced into the tubular sheath of the introducer in order to advance an artificial valve intended to replace the heart valve, the guide wire comprising a metal part also acting as a connection to the other electrode of the external cardiac stimulator.
An assembly for replacing a heart valve by the percutaneous route, comprising:
- a device forming a valve delivery catheter comprising at least one tubular introduction sheath, intended to be introduced into an artery of a human body;
- a sleeve adapted to be fitted around the introduction sheath, the sleeve being made of electrically conductive material on at least one part of the outer periphery thereof so that, when the sheath is introduced into the artery of a human body with the sleeve fitted around the sheath, the conductive periphery of the sleeve is in contact with the subcutaneous tissue of the body or with the artery, the sleeve further comprising an electrical connection to an electrode of a cardiac stimulator outside the body;
- at least one guide wire intended to be introduced into the tubular sheath of the delivery catheter in order to advance an artificial valve intended to replace the heart valve, the guide wire comprising at least one metal part also acting as a connection to the other electrode of the external cardiac stimulator.
An assembly for replacing a heart valve by the percutaneous route, comprising:
- a device forming an introducer comprising at least one tubular introduction sheath, intended to be introduced into an artery of a human body (C) and to allow through a surgical intervention device;
- a transcutaneous electrode comprising an adhesive part intended to be adhered to the skin of the human body into which the sheath is introduced, and a part made of electrically conductive material so that, when the adhesive part is adhered to the skin, the conductive part can deliver a current transcutaneously, the conductive part further comprising an electrical connection to an electrode of a cardiac stimulator outside the body;
- at least one guide wire intended to be introduced into the tubular sheath of the introducer in order to advance an artificial valve intended to replace the heart valve, the guide wire comprising a metal part also acting as a connection to the other electrode of the external cardiac stimulator.

- a transcutaneous electrode comprising an adhesive part intended to be adhered to the skin of the human body into which the sheath is introduced, and a part made of electrically conductive material so that, when the adhesive part is adhered to the skin, the conductive part can deliver a current transcutaneously, the conductive part further comprising an electrical connection to an electrode of a cardiac stimulator outside the body;
- at least one guide wire intended to be introduced into the tubular sheath of the delivery catheter in order to advance an artificial valve intended to replace the heart valve, the guide wire comprising at least one metal part also acting as a connection to the other electrode of the external cardiac stimulator.
An assembly for replacing a heart valve by the percutaneous route, comprising:
- a device forming an introducer comprising at least one tubular introduction sheath intended to be introduced into an artery of a human body (C) and to allow through a surgical intervention device;
- at least one guide wire, called bipolar guide wire, intended to be introduced into the tubular sheath in order to advance an artificial valve intended to replace the heart valve, the guide wire comprising a metal core coated with an electrically isolating sheath on a central portion between the proximal end and the distal end of the guide wire, the metal core being non-electrically isolated on the remainder of the length of the guide wire, the electrically isolating sheath integrating an electrically conductive element, for which a distal portion is apparent on at least one part of the outer periphery of the isolating sheath so as to be in contact with the subcutaneous tissue of the body or with the artery and for which a proximal portion is apparent on at least one part of the outer periphery of the isolating sheath so as to be accessible from outside the body (C) when the guide wire is introduced into the introduction sheath, with the proximal portion acting as a connection to an electrode of a cardiac stimulator outside the body, whereas the metal core of the bipolar guide wire acts as a connection to the other electrode of the external cardiac stimulator.
