Description

Segmented Balloon Catheter for Stentinq Bifurcation Lesions Background of the Invention

The present invention relates to a balloon catheter which may be used to deliver and deploy a stent in a blood vessel. More particularly, the invention relates to a segmented balloon catheter which may be used to deploy one or more stents in a bifurcation of the blood vessel in order to treat an occlusion or lesion occurring in or near the bifurcation.

Balloon catheters are commonly used to treat certain conditions of a blood vessel, such as a partial or total occlusion or lesion of the vessel which may be caused by, for example, atherosclerotic plagues or thrombosis. In an angioplasty procedure, the balloon portion of the catheter is advanced over a guide wire to the site of the occlusion and inflated to compress the occlusion and thereby restore normal blood flow through the vessel. In some instances, a stent may be implanted in the blood vessel to prevent the occlusion from recurring. A balloon catheter is commonly used to deliver and deploy the stent in such a stenting or stent implantation procedure. The stent is typically mounted in its unexpanded state on the balloon portion of the catheter, delivered to the site of the occlusion and then deployed or implanted in the vessel by inflating the balloon portion. Prior art stenting procedures often are unsuitable for treating a condition of a blood vessel occurring at or near a bifurcation of the blood vessel, that is, the intersection of a main vessel with a side branch vessel. One method for stenting an occlusion in a bifurcation involves implanting a first stent in the main vessel adjacent the bifurcation and then implanting a second stent in the side branch vessel adjacent the bifurcation (the so-called "T-stenting" procedure). However, this requires that the guide wire for the balloon catheter which is used to deliver the second stent be threaded through the struts of the first stent and into the side branch vessel. This process can be quite difficult and time consuming. Furthermore, the stenting of the main vessel may shift plagues and thereby close off the side branch vessel, making it extremely difficult to insert the guide wire into the side branch vessel.

Also, prior to stenting, the occlusion is commonly pre-dilated using a balloon angioplasty procedure. In preparation for a balloon angioplasty procedure in a bifurcation, a first guide wire is inserted into the main vessel and a second guide wire is inserted into the side branch vessel. Thus, even if shifting plagues should close off the side branch vessel during dilation of the main vessel, the side branch vessel can still be approached via the second guide wire. However, in prior art stenting procedures for occlusions in bifurcations, the second guide wire must usually be withdrawn from the side branch vessel prior to stenting the main vessel so that it will not interfere with the deployment of the stent in the main vessel. Consequently, difficulty may be experienced in inserting the second guide wire back into the side branch vessel prior to stenting or otherwise re-treating the side branch vessel. Summary of the Invention

In accordance with the present invention, these and other disadvantages in the prior art are addressed by providing a segmented balloon catheter for use in treating a condition of a vessel occurring near a bifurcation that is defined by the intersection of a main vessel with a side branch vessel. The segmented balloon catheter comprises a shaft which includes a proximal end, a distal end and a longitudinal passageway that extends therethrough from the proximal end to the distal end; a first balloon portion which is mounted on the shaft adjacent the distal end; and a second balloon portion which is mounted on the shaft adjacent the first balloon portion. The shaft also comprises a transverse port which extends between the longitudinal passageway and the exterior of the segmented balloon catheter from between the first and second balloon portions. A proximal end of a first guide wire which is pre-positioned in the main vessel may be inserted into the distal end of the shaft and threaded through the longitudinal passageway and out the proximal end of the shaft. In addition, a proximal end of a second guide wire which is pre-positioned in the side branch vessel may be inserted into the transverse port and threaded through the longitudinal passageway and out the proximal end of the shaft. In this manner, the first and second balloon portions may be guided to the bifurcation on the first and second guide wires. In accordance with one embodiment of the invention, the segmented balloon catheter also comprises a stent which is mounted on the first and second balloon portions. In addition, the stent may comprise a window which is aligned with the transverse port in the shaft and through which the second guide wire extends. In this manner, the segmented balloon catheter may be used to deliver and deploy the stent in the main vessel adjacent the bifurcation. Furthermore, a second balloon catheter may then be threaded onto the second guide wire and used to deliver a second stent through the window and into the side branch vessel adjacent the bifurcation. Thus, the segmented balloon catheter of the present invention provides a simple and efficient means for treating a condition of a blood vessel occurring at or near a bifurcation of the blood vessel. Since the segmented balloon catheter requires the pre-positioning of the first and second guide wires in the main and side branch vessels, respectively, the second guide wire can remain in place in the side branch vessel after a pre-dilation procedure, thereby eliminating the need to withdraw the second guide wire prior to stenting the main vessel. Also, since the second guide wire is threaded through the lateral port between the first and second balloon portions, the second guide wire will guide the placement of the first and second balloon portions across the opening to the side branch vessel. In addition, because the second guide wire is threaded through the stent before it is introduced into the vessel, the second guide wire may remain in position while the stent is deployed in the main vessel, thereby eliminating the need to thread the second guide wire through the stent after the stent is deployed in the main vessel. Furthermore, since a second stent may be deployed in the side branch vessel on the second guide wire, the first guide wire may remain in the main vessel during the stenting of the side branch vessel in the event the main vessel requires a subsequent treatment.

These and other objects and advantages of the present invention will be made apparent from the following detailed description, with reference to the accompanying drawings. In the drawings, the same reference numbers are used to denote similar elements in the various embodiments. Brief Description of the Drawings

Detailed Description of the Preferred Embodiments

The present invention is directed to a balloon catheter which is particularly useful in delivering and deploying a stent at or adjacent a bifurcation in a blood vessel. The invention may be used with any conventional balloon catheter delivery system, including the over-the-wire balloon system or the rapid exchange balloon system. In addition, the invention may be used to deploy any conventional balloon-deployable stent. Therefore, the scope of the present invention should not be limited to the exemplary delivery system and stents discussed below.

Referring to Figure 1 , the segmented balloon catheter of the present invention, which is indicated generally by reference number 10, is shown to comprise an elongated shaft 12 which includes a distal end 14 and a proximal end (not shown), a first cylindrical balloon portion 16 which is mounted on the distal end, and a second cylindrical balloon portion 18 which is mounted on the distal end adjacent the first balloon portion. Each balloon portion 16, 18 is made of a conventional material, such as a polyolefin copolymer, and is secured and sealed to the shaft 12 by suitable means, such as via heat bonding or an appropriate adhesive. More preferably, the first and second balloon portions 16, 18 comprise separate portions of a single balloon head 20 which comprises a proximal end 22, a distal end 24 and a midpoint 26 which lies between the first and second balloon portions. Moreover, the balloon head 20 is ideally secured and sealed to the shaft 12 at its proximal and distal ends 22, 24, and preferably also at its midpoint 26.

The shaft 12 comprises a longitudinal passageway 28 that extends axially therethrough between the distal end 14 and the proximal end. The shaft 12 also includes a transverse port 30 that extends between the longitudinal passageway 28 and a corresponding hole 32 which is formed in the balloon head 20 between the first and second balloon portions 16, 18. The shaft 12 may be made of any suitable material, such as polyethylene.

In the embodiment of the invention shown in Figure 1 , the shaft 12 comprises an inner tube 34 which has a distal end 36 and an outer tube 38 which, has a distal end 40, and the inner and outer tubes are secured and sealed together at their distal ends to define an inflation passageway 42 between the inner and outer tubes that is separated from the longitudinal passageway 28. Furthermore, the inflation passageway 42 communicates with the interior of each of the first and second balloon portions 16, 18 via respective first and second inflation holes 44, 46 which extend transversely through the outer tube 38. In this manner, an inflation fluid from an inflation device (not shown) may be communicated through the inflation passageway 42 to inflate the first and second balloon portions 16, 18. As shown in Figure 1 , the balloon head 20 is ideally sealed to the outer tube 38 around the hole 32, and the outer tube is sealed to the inner tube 34 around the transverse port 30, so that the inflation fluid will not exit the inflation passageway 42 through either the hole or the port.

In an alternative embodiment of the invention which is shown in Figure 2, the segmented balloon catheter, which is indicated generally by reference number 10', is shown to comprise a balloon head 20 that is secured to the distal end 14 of a modified shaft 12'. As in the previous embodiment, the balloon head 20 includes a first balloon portion 16, a second balloon portion 18, a proximal end 22, a distal end 24 and a midpoint 26 which lies between the first and second balloon portions. In addition, the shaft 12' includes an inner tube 34 having a distal end 36 and an outer tube 38 having a distal end 40. However, in this embodiment the distal end 36 of the inner tube 34 is spaced axially from the distal end 40 of the outer tube 38. Furthermore, the proximal end 22 of the balloon head 20 is secured and sealed to the distal end 40 of the outer tube 38, and the distal end 24 of the balloon head is secured and sealed to the distal end 36 of the inner tube 34. In addition, the midpoint 26 of the balloon head 20 ideally comprises an inner diameter which is greater than the outer diameter of the inner tube 34. In this manner, fluid from the inflation device (not shown) may be communicated to the first and second balloon portions 16, 18 directly via the inflation passageway 42 that is formed between the inner and outer tubes 34, 38 of the shaft 12'. In addition, the balloon head 20 is ideally sealed to the inner tube 34 around the hole 32 to prevent the inflation fluid from exiting the balloon head through the hole.

In an alternative to the present invention which is not illustrated in the drawings, the segmented balloon catheter 10, 10' could comprise a separate inflation lumen which is connected between the inflation device and each of the first and second balloon portions 16, 18. Such an inflation lumen could be positioned within or radially outside of the shaft 12, 12'. The construction and operation of such an alternative will be readily apparent to the person of ordinary skill in the art.

Referring now to Figure 3, the segmented balloon catheter 10, 10' of the present invention may be used to deliver and deploy a stent 48 in a blood vessel (not shown). The stent 48 may be any conventional balloon expandable stent which is used to treat a condition of a blood vessel, such as an occlusion or lesion that is caused by, for example, a stenosis or restenosis of the vessel. In one embodiment of the invention, the stent 48 is ideally a drug eluting or drug coated stent, which will help prevent restenosis following implantation of the stent. An example of a drug eluting stent and a method for making the same is disclosed in U.S. Patent No. 6,206,915, which is hereby incorporated herein by reference.

The stent 48 is removably mounted on the balloon head 20 of the segmented balloon catheter 10, 10'. Furthermore, for reasons which will be made apparent below, the stent 48 preferably comprises an enlarged cell or window 50 which is aligned with the hole 32 in the balloon head 20. In its unexpanded condition shown in Figure 3, the stent 48 comprises a diameter which is approximately the same as or slightly larger than the diameter of the uninflated first and second balloon portions 16, 18. When the first and second balloon portions 16, 18 are inflated, the stent 48 will expand into its expanded or deployed condition shown in Figure 4. The segmented balloon catheter 10, 10' of the present invention is particularly useful in treating an occlusion occurring at or near a bifurcation of a blood vessel. As shown in Figure 4, a bifurcation 52 is the site where a main vessel 54 is intersected by a side branch vessel 56. The occlusion, which may be caused by a stenosis or restenosis in the blood vessel, may be located in the main vessel 54 upstream of the side branch vessel 56, in the main vessel downstream of the side branch vessel, at the intersection of the main vessel and the side branch vessel, in the side branch vessel downstream of the main vessel, or in a combination of any of these locations. As will be made apparent below, the segmented balloon catheter 10, 10' may be used to deploy the stent 48 to treat an occlusion occurring in any of these locations.

Prior to commencing the stenting procedure of the present invention, the main vessel 54 and the side branch vessel 56 may be pre-dilated in a conventional balloon angioplasty procedure. In preparation for such a pre- dilation procedure, a first conventional guide wire 58 is positioned in the main vessel 54 and a second conventional guide wire 60 is positioned in the side branch 56, as shown in Figure 5. After the pre-dilation procedure is completed, the balloon catheter which is used in such a procedure is removed and the segmented balloon catheter 10, 10' with the stent 48 mounted thereon is threaded onto both of the guide wires 58, 60 as follows. The proximal end of the first guide wire 58 (that is, the end closest to the doctor) is inserted into the distal end 36 of the inner tube 34 and threaded through the longitudinal passageway 28 until it exits the proximal end of the shaft 12, 12'. The proximal end of the second guide wire 60 is then inserted through the window 50 in the stent 48, the hole 32 in the balloon head 20 and the transverse port 30 in the shaft 12, 12'. The second guide wire 60 is then threaded through the longitudinal passageway 28 until it exits the proximal end of the shaft 12, 12'. The balloon head 20 and stent 48 are then advanced through the main vessel 54 to the bifurcation 52, as shown in Figure 6. Since the second guide wire 60 is threaded through the lateral port 30 between the first and second balloon portions 16, 18, the second guide wire will help position the first and second balloon portions in the main vessel 54 across the opening to the side branch vessel 56.

Once the stent 48 is in position at the bifurcation 52, the first and second balloon portions 16, 18 are inflated to expand the stent 48 into its deployed condition, as shown in Figure 7. The first and second balloon portions 16, 18 are then deflated to allow the segmented balloon catheter 10, 10' to be withdrawn from the bifurcation 52 and removed from the first guide wire 58. When the stent 48 is deployed as just described, the second guide wire 60 will automatically be positioned through the window 50, as shown in Figure 8. If necessary, the segmented balloon catheter 10, 10', or any conventional balloon catheter, can then be threaded onto the second guide wire 60, advanced partially into the side branch 56 and inflated to align the window 50 with the side branch.

If necessary, a second stent may be implanted in the side branch 56 to treat an occlusion located at or near the bifurcation 52. Referring to Figure 9, this may be accomplished by first threading a second balloon catheter 62 having a second stent 64 mounted thereon onto the second guide wire 60. The second balloon catheter 62 may be similar to the segmented balloon catheter 10, 10', or it may simply be any conventional balloon catheter. Similarly, the second stent 64 may be similar to the stent 48, or it may by any standard balloon expandable stent. The second balloon catheter 62 is advanced through the window 50 in the stent 48 and into the side branch 56. The second balloon catheter 62 is then inflated to expand the second stent 64 into its deployed condition in the side branch 56. The second balloon catheter 62 may then deflated and removed. As shown in Figure 10, the second stent 64 is preferably positioned such that a portion of the stent is located at the intersection of the main and side branch vessels 54, 56. This will ensure that any occlusion which may exist at the intersection will be suitably engaged by the stents 48, 64. It should be recognized that, while the present invention has been described in relation to the preferred embodiments thereof, those skilled in the art may develop a wide variation of structural and operational details without departing from the principles of the invention. For example, the various elements shown in the different embodiments may be combined in a manner not illustrated above. Therefore, the appended claims are to be construed to cover all equivalents falling within the true scope and spirit of the invention.
