- 75A, 75B extends in an insulation conduit 29A, 29B between its distal passage 39A, 39B and the control passage 27A, 27B of the corresponding control branch 25A, 25B.
- Each isolation duct 29A, 29B therefore receives a single control section 75A, 75B which is isolated from the duct 41.
- the duct 41 for circulating the guide 43 in the central passage 14 is devoid of retaining wire 53A, 53B. between the proximal end 21 of the stent and the proximal retaining opening 23A 1 which allows the passage of the guide 43 without mechanical interaction with the son 53A, 53B.
- a control end 77A, 77B of the control section 75A, 75B is engaged through the control passage 27A, 27B.
- a portion 79A, 79B of this portion protrudes out of the branch 25A, 25B through the plug 35A, 35B.
- the length of this projecting portion 79A, 79B is variable and controls the length of the clamping loop 73A, 73B.
- an increase in the length of the projecting portion 79A, 79B causes the control section 75A, 75B to move relative to the stent 13, towards the proximal end 21 of this stent, as well as a corresponding decrease in the active length of the clamping loop 73A, 73B, and hence the clamping of the stent 11 against the stent 13, at the clamping loop 73A, 73B.
- control section 75A, 75B is in a tensioned position.
- a decrease in the length of the projecting portion 79A, 79B causes the displacement of the control portion 75A, 75B with respect to the stent 13 towards the distal end 19 of the stent, as well as an increase in the active length of the stent.
- control section 75A, 75B When the stent 11 is in its expanded state, the control section 75A, 75B is in a relaxed position.
- Each plug 35A, 35B comprises a central lumen of adjustable diameter in which is engaged the projecting portion 79A, 79B.
- the projecting portion 79A, 79B of the control section 75A, 75B is selectively immobilized with respect to the guard 13 and the length of the protruding portion 79A, 79B and hence the active length of the clamping loop 73A, 73B.
- the control beam 54 comprises a handle 81 and releasable means 83A, 83B for fixing the ends of the control sections 75A, 75B located on either side of the handle.
- the handle 81 is located outside the passage 14 away from the guard 13.
- control sections 75A, 75B, at the projecting portions 79A, 79B are respectively fixed on either side of the handle 81 of the spreader bar 54.
- the spreader bar 54 allows the simultaneous actuation of the two control wires 53A, 53B with one hand, as will be seen below.
- the device is kept in a package (not shown), with the stent 11 in an expanded state similar to that shown in FIG.
- control rod 51 is in its retaining position.
- the distal and proximal retaining threads 53A and 53B are engaged in the stem 51 and in the mesh of the stent 11.
- This packaging retains the mechanical properties of the stent 11, particularly when the tubular lattice thereof is embedded in an extensible and waterproof film, such as an elastomer.
- the surgeon extracts the device from its packaging. He implanted the surgical guide 43 circulating in the blood vessel or vein from the point of external introduction to the area of the vein or artery into which the tubular stent is to be implanted.
- a third step for implantation of the stent 11 into the blood vessel or vein, the surgeon simultaneously actuates the retaining wires 53A and 53B by pulling the handle 81 away from the stent 13 to to increase the length of the projecting portion 79A, 79B of the control section 75A, 75B. It thus simultaneously moves the control sections 75A, 75B towards the proximal end 21 of the guard 13. The length active of each tightening loop 73A, 73B decreases so that the stent 11 is retracted against the guard 13 and fixed firmly relative to the guard 13.
- a sheath (not shown) is disposed around the stent 11 prior to this introduction and removed once the introduction has been made.
- the stent 11 is then in the retracted state illustrated in FIG. 1 in which the mesh is substantially in abutment against the stent 13. It is thus introduced to its place of implantation by displacement along the surgical guide 43.
- the guide 43 is introduced into the central passage 14 through the distal passage opening 22A.
- the introduction of the guide 43 into the passage 14 is facilitated by the beveled shape of the distal ends of the conduits 29A, 29B.
- the guide 43 is free to circulate in the duct 41, without encountering wires 53A, 53B.
- the guide 43 When the end of the guide 43 reaches the proximal end 21 of the guardian, the guide 43 enters the central channel 65 of the cap 59.
- the divergent shape of the sleeve 61 at the inlet 67 also allows easy guidance of the guide 43 The guardian carrying the stent is then moved along the guide 43.
- the operating surgeon gradually decreases the length of the protruding portion 79A of the control portion 75A by releasing it from the plug 35A. With the aid of the spreader 54, it moves the control section 75A towards the distal end 19 of the guard 13. As a result, the active length of the clamping loop 73A increases. The lattice of the stent 11 then spontaneously deforms from the compressed state shown in FIG. 1 in the expanded state shown in FIG. 4.
- control sections 75A, 75B of the retaining wires 53A, 53B are simultaneously released from their plugs 35A, 35B.
- the surgeon then simultaneously maneuvers the two control sections 75A, 75B using the handle 81 of the rudder bar.
- it can simultaneously deploy both ends 15, 85 of the stent 11 by moving the two ends 83A, 83B of the handle 81 to the plugs 35A, 35B.
- It can also deploy one end 15, 85 of the stent holding the other end of the retracted stent against the stent 13 by moving one end 83A, 83B of the handle 81 to the plug 35A, 35B associated.
- the spreader 54 thus facilitates the operation of the device and allows to select with one hand the deployment or retraction of one and / or the other end of the stent 11.
- the distal passage 39B is located at the distal end 33B of the insulation conduit 29B.
- the insulation duct 29B also has around the passage 39B at its distal end 33B a collar 87 for application to the wall 13A of the guardian.
- the duct 29B is bent in the vicinity of its distal end 33B, which is engaged through the retaining aperture 23B.
- the collar 85 rests on an outer surface 89 of the guard 13 around the opening 23B and fixes the conduit 29B to the guard 13.
- the guard 13 comprises a central duct 91 for circulating the guide formed by a tubular portion of axis XX 'disposed in the central passage 14 and extending to the proximal end 21 of the guardian.
- the central duct 91 is connected to the wall 13A of the guard 13 by plane axial walls 95.
- the axial walls 95 have a cross section extending radially away from the axis X-X '. They delimit between the central duct 91 and the wall 13A a plurality of insulation ducts 29A, 29B which receive the retaining son 53A, 53B.
- the duct 91, the wall 13A and the walls 95 are integral, the guard 13 can be made for example by extrusion.
- Each channel 37A, 37B thus has a truncated angular sector-shaped cross section which covers a portion of the annular surface extending between the duct 91 and the wall 13A of the tutor about the axis X-X '.
- the angle formed by two axial walls 95 adjacent is for example between 10 and 150 degrees.
- the plug 59 is formed so that the inner surface of the sleeve 61 is flush with the inner surface. duct 91, to facilitate the passage of the guide between the duct 91 and the plug 59.
- the releasable retaining son 53A, 53B of the stent 11 being disposed in insulating conduits 29A, 29B, the risk of mechanical interaction between these son 53A, 53B and the guide 43 is greatly reduced. Moreover, the maneuvering of the control sections 75A, 75B of these wires is rendered extremely reliable thanks to their arrangement in the internal insulation ducts 29A, 29B.
- the spreader 54 applies to other types of medical implant deployment devices comprising at least two control wires, in particular those having no insulation conduits 29 as described in the application FR 2 863 160.
- the presence of diverging surfaces at the ends 19, 21 of the guard 13 facilitates insertion of the guide 43 into the central passage 14, either from the distal end to the proximal end of the guard 13, or in the opposite direction.
