Definitions
- the present invention relates to a method and apparatus for use in dilating occluded blood vessels.
- the invention is particularly concerned with such a method and apparatus wherein dilatation is achieved through means of a balloon element of large diameter which is inflated to com ⁇ press the occlusion being treated and wherein the transverse dimension of the non-inflated balloon element may be reduced to a minimal condition to enable placement of the catheter properly within the lumen of an occluded artery or vein.
- the catheter is provided with a balloonable wall portion which, both in its non-inflated and inflated conditions, has a diameter several times that of the balance of the catheter.
- This poses the problem as to how to pass the balloonable , portion of the catheter conveniently and properly within the lumen of an occluded artery or vein.
- This problem is solved by axially twisting the balloonable portion so as to decrease its large non-inflated diameter to a reduced diameter of comparable size to that of the balance of the catheter for emplacement of the catheter. The balloonable portion is then untwisted in place to enable it to be blown up.
- a principal object of the invention is to provide an inflatable dilatation catheter with a large diameter expansible portion and means to reduce the diameter thereof in the non-inflated condition to a size ' which may be conveni ⁇ ently and efficiently moved into place within an occluded blood vessel.
- Another object of the invention is to provide such a catheter with fluid sealing means which is in sealed condi ⁇ tion when the diameter of the non-inflated inflatable portion
- SPREAD- OMPI is large and which is in unsealed condition when the diameter of the on-inflated inflatable portion is small.
- Fig. 1 is a view partly in perspective and partly in section of the subject catheter and an occluded artery.
- Fig. 2 is an enlarged view in section of the sub- ject catheter. '
- Fig. 3 is a view partly in elevation and partly in section showing the subject catheter emplaced in an occluded artery and ready for inflation of the dilatation element.
- Fig. 4 is a view similar to that of Fig. 3 but showing the dilatation element in inflated condition.
- Fig. 5 is a similar view showing the catheter in condition for removal from the artery.
- Fig. 1 illustrates a blood vessel 10 which is partially occluded by an extended occlusion 12.
- the vessel takes the form of an artery and the occlusion is what is commonly known as an arteriosclerotic plague or atheroma. This is the type of adhering occlusion with which the subject apparatus and method is expected to find primary application.
- the in ⁇ ventions are applicable in treating other types of occluded vessels where dilatation is desired.
- the in ⁇ ventions may be used in treating occlusions resulting from fibromuscular displasia in veins.
- the catheter 14 comprises a flexible plastic tube
- Tube 16 is fixedly attached to an internally threaded coupling member 28 which is attached to the externally threaded end of a T-shaped fitting 30.
- the proximal end of fitting 30 is provided with internal threads 32 with which the externally threaded stem portion 34 of control knob 36 is threadably engageable.
- Control knob 36 is fixedly attached to wire 18.
- the knob stem 34 is normally fully threadably engaged with fitting 30 to thereby position the sealing disc 38 carried . by knob 36 in sealing engagement with the proximal end 40 of fitting 30.
- a syringe 42 is connected to the proximal end of the catheter 14 through the fitting 30.
- the syringe is to be filled with an incompressible fluid, and a plunger 44 forming part of the syringe and a control valve 46 constitute means whereby this fluid may be selectively charged into or released from the dilatation bag or balloon 22 through the tube 16.
- the catheter is used in the following manner.
- the knob 36 is rotated to back it off from the fitting 30 to approximately the position shown in Figs. 1 and 2.
- the wire 18 and tip 20 are thereby rotated to wind up or twist the bag 22 to thereby materially reduce the non-inflated diameter of the bag to a value .of that of tube 16 or less.
- the tip 20 moves closer to the distal end of tube 16 and the bag 22 becomes shortened in corresponding relation to the degree of twist imparted thereto.
- the more and tighter the balloon is twisted the lesser becomes its diameter and the greater is the stiff ⁇ ness imparted to the balloonable section of the catheter by the twisted condition of the balloon.
- the twisted condition of the balloon due to the greatly reduced non-inflated dia ⁇ meter thereof and to the proportionately increased stiffness thereof, contributes substantially to the efficient feeding of the catheter along the blood vessel and to its desired
- the catheter is introduced into vessel 10 through an incision, not shown.
- the control knob 36 is once again backed off from the fitting 30, as illustrated in Fig. 5, to move the sealing disc 38 away from the fitting and wind up or twist the bag 22
- the twisting of the bag and consequent reduction of its diameter forces the fluid out of the bag and causes it to, drain out of the catheter through the now unsealed end 40 of fitting 30.
- the catheter may then be moved to a new section of atheroma to be treated or be withdrawn from the vessel, as the case may be.
- the catheter may be provided with a quick-connect connection between knob 36 and fitting 30 such that in a turn or less of the knob the latter is either fully connected or fully disconnected relative to fitting 30. In such an embodiment substantially all of the twisting and untwisting of the balloon element takes place while the knob is fully disconnected from fitting 30.
- the apparatus and method the present invention are ideally suited for the dilatation of elongate arterial occlusions by progressive and incremental dilatation, and in particular where it is important that the inflated dia ⁇ meter of the balloon element be several times the diameter of the catheter tube. Due to the mechanical contraction technique employed, the balloon element (bag 22) may provide for such inflation while being of a highly flexible thin- walled generally inelastic construction. It is to be understood, however, that this invention is not intended to be limited to the specific details described above but is rather to be defined by the terms of the appendant claims.

Abstract
Un catheter (14) a dilatation est pourvu d'une section (22) gonflable qui, dans sa position non gonflee, peut avoir un diametre egal a plusieurs fois le diametre de la partie restante du catheter. Des moyens sont prevus pour tordre axialement la partie gonflable du catheter de maniere a reduire son diametre dans sa condition non gonflee a une taille comparable a celle de la partie non gonflable du catheter, de facon a pouvoir introduire et positionner le catheter a l'interieur d'un vaisseau sanguin (10).
