Abstract
An assembly for placement of a cardiac, aortic or arterial implant. The assembly includes an insertion sheath of an introducer or of a delivery catheter, which is of a size smaller than that of an introducer, intended to be introduced into an artery of a human body. The metal support of an electrode of the external cardiac stimulator being integrated into the insertion sheath of a peripheral venous or arterial accessory catheter, or a sleeve around the accessory catheter, which is introduced into the peripheral vein or artery of a patient. The sheath of the accessory catheter or the sleeve is therefore directly in contact with a peripheral vein or artery of the patient.
Claims12
An assembly for placement of a cardiac, aortic or arterial implant, comprising:
- a device forming an introducer or a valve delivery catheter comprising at least one tubular insertion sheath, intended to be introduced into an artery of a human body;
- an accessory catheter intended to be introduced into a peripheral vein or artery of the human body;
- a sleeve adapted to be engaged around the accessory catheter, the sleeve being made of electrically conductive material over at least part of its outer periphery, such that, when the accessory catheter is introduced into the peripheral vein or artery of the human body, the conductive periphery of the sleeve is in contact with the subcutaneous tissue of the body or with the wall of the artery or of the vein, the sleeve additionally comprising an electrical connection to an electrode of a cardiac stimulator outside the body;
- a guidewire intended to be introduced into the tubular sheath of the introducer or of the delivery catheter for advancing the implant, the guidewire comprising a metal part additionally serving as a connection to the other electrode of the external cardiac stimulator.

- a device forming an introducer or a valve delivery catheter comprising at least one tubular insertion sheath, intended to be introduced into an artery of a human body;
- an accessory catheter, intended to be introduced into a peripheral vein or artery of the human body, the accessory catheter comprising at least one tubular insertion sheath and at least one electrically conductive element, of which a distal portion is exposed on at least one part of the outer periphery of the sheath in such a way as to be in contact with the subcutaneous tissue of the body or with the peripheral vein or artery, and of which a proximal portion, accessible from the outside of the body, comprises an electrical connection so as to serve as a connection to an electrode of a cardiac stimulator outside the body;
- a guidewire intended to be introduced into the tubular sheath of the introducer or of the delivery catheter for advancing the implant, the guidewire comprising a metal part additionally serving as a connection to the other electrode of the external cardiac stimulator.
