Definitions
- Catheter for transvascular stimulation and denervation of a part of an autonomic nervous system of a human body in particular transvascular renal nerve stimulation or stimulation of the carotid glomus.
- the present invention relates to a catheter for transvascular stimulation and denervation of a portion of an autonomic nervous system of a human body.
- the line and the branches are hollow with at least part of the free end of the latter being pointed to form a plurality of alcohol injection needles.
- denervation can be achieved by injection of alcohol.
- a guide catheter 1 is introduced into a femoral artery.
- An elongated deployment element 4 is slidably mounted in the tubular deployment sheath 3.
- the proximal end 41 of the electrical conduction line is electrically connected to an external electrical pulse generator 5.
- the structure 42 is deployed with, in this deployed position, at least part of the contact points 420 and, where appropriate, piezoelectric actuators and, where appropriate, needles in contact with at least one peripheral zone of the blood vessel to electrically stimulate the part of the autonomic nervous system around the peripheral zone by sending an electric current.
- Figure 3 shows, as structure 42, an assembly of curved and mutually independent metal branches 422, connected at their base to the electrical conduction line, which delimit an axisymmetric umbrella-type shape.
- This method is applied when a practitioner wishes to make a diagnosis of the renal artery followed by denervation and preferably a verification or completeness of one or more denervated areas.
- Step i/ a practitioner then introduces the guide catheter 1 into a femoral artery of a human body C.
- Step ii/ the practitioner then introduces the catheter 2 into the introduction sheath of the guide catheter 1, until ensuring that the distal end 42 is well positioned in the renal artery AR to be diagnosed and denervated.
- Step iii/ The practitioner iii/ slides the elongated element 4 in the tubular deployment sheath 3 from a folded position to a deployed position.
- the structure 42 is then deployed with at least part of the contact points and, if applicable, piezoelectric actuators and, if applicable, needles in contact with at least one peripheral zone Z1, Z2 or Z3 of the blood vessel (figure 2 or 3).
- the current delivered by the generator 5 can be of the order of 15mA to 25mA with a pulse frequency between 200 and 2000/min (10 to 20 Hz) for 1 min.
- the response to this stimulation is then measured for each area of the nervous system S with respect to the area in contact with the different contact points 420. This is how the mapping of the peripheral areas is carried out.
- electrical denervation is then carried out or, where appropriate, denervation by ultrasound produced by the piezoelectric actuators or by injection of alcohol into the needles, in said deployed position.
- Step v/ electrical stimulation of one or more peripheral areas denervated according to step iv/ is carried out by sending an electric current using the generator 5 so as to carry out a check of the denervation carried out.
- the introduction of the guide catheter or introducer is done via the femoral route, that is to say in the femoral artery at the level of the groin, it can also be done via the radial route, that is to say in the radial artery at the level of the patient's wrist.
- an introducer can be used.
