Abstract
The present application relates to an assembly for replacing a heart valve or coronary angioplasty assembly, including an insertion sheath (13) of an introducer (1) or a delivery catheter (1′), which is smaller in size than an introducer, intended for being inserted into an artery of a human body. The application involves integrating the metal substrate of an electrode of the cardiac stimulator directly into the sheath for insertion into the artery of a patient.
Claims19
A method for replacing a heart valve of a patient's heart by a percutaneous route, the method comprising:
- introducing a tubular insertion sheath into an artery of the patient;
- contacting a subcutaneous tissue of the body or of the artery with an electrically conductive element provided at an outer periphery of a distal portion of the insertion sheath;
- introducing a guide wire into the insertion sheath for advancing an artificial valve intended to replace the heart valve of the patient's heart;
- positioning the distal portion of the insertion sheath having the electrically conductive element proximal to the distal end of the guide wire;
- contacting a wall of the left ventricle of the patient's heart with a distal end of the guidewire;
- introducing a surgical intervention device over the guide wire and into the insertion sheath including the artificial valve;
- connecting an electrode of a cardiac stimulator to a proximal end of the guide wire;
- and
- connecting another electrode of the cardiac stimulator external to the body so as to be connected only to the electrically conductive element and not to the guide wire.
A method for replacing a heart valve of a patient's heart by a percutaneous route, the method comprising:
- providing a catheter device having a distal electrically conductive portion exposed at an external periphery of a distal portion of the catheter device spaced from a distal-most end face of the catheter device, and also having a proximal electrically conductive portion exposed at an external periphery of a proximal portion of the catheter device opposite the distal portion of the catheter device and in electrical communication with the distal electrically conductive portion;
- providing a guide wire having a distal non-insulated end, a proximal non-insulated end, and an insulated section disposed therebetween;
- inserting the catheter device into the patient and inserting the guide wire into the catheter device;
- positioning the distal end of the guide wire spaced from the distal portion of the catheter device and in a different chamber or vessel of the patient's heart than the distal electrically conductive member;
- and
- electrically stimulating the patient's heart by connecting each of the proximal end of the guide wire and the proximal electrically conductive portion to a cardiac stimulator.
A method for replacing a heart valve of a patient's heart by a percutaneous route, the method comprising:
- inserting a distal end of a catheter device into the left ventricle of the patient's heart such that a discrete electrically conductive aspect located along the distal end of the catheter device is in contact with internal tissue of the left ventricle;
- inserting a distal end of a guide wire into the catheter device such that the distal end of the guide wire is in electrical communication with a chamber or vessel of the patient's heart;
- arranging the distal end of the guide wire and the electrically conductive aspect such that they are in electrical communication with one another only through tissue of the patient's heart and through a cardiac stimulator, thereby completing an electrical circuit including the patient's heart;
- inserting a replacement heart valve through the catheter device;
- and
- directing an electrical current through the electrical circuit when the replacement heart valve is disposed within the catheter device and insulated from the electrical circuit.
