摘要： A catheter tip for attachment with an intravascular balloon catheter that is used within a body lumen is disclosed. The catheter tip includes a body portion having a base that is attached to the balloon catheter. The base defines a proximal end of the catheter tip. A head that is attached to the body portion defines a distal end of the catheter tip. An axial cavity, cooperatively defined by the body portion and the head, extends longitudinally from the proximal to the distal end of the catheter tip. The axial cavity receives a first guidewire along which the catheter is moved within the body lumen. An outer surface of the head is shaped in a predetermined manner to control the magnitude of deflection of a second guidewire that is often twisted about the first guidewire in the lumen so as to prevent catheter obstruction by the guidewires during catheter procedures.

摘要： A contoured intraluminal stent for deployment proximate a bifurcated vessel is disclosed. The contoured stent is configured to seat within a side branch of the bifurcated vessel so as to acceptably cover a curvilinear ostium defined at the intersection of the side branch with a main branch of the vessel. A stent deployment system includes a first guidewire positioned in the vessel main branch and a second guidewire that extends through the main branch and into the vessel side branch, wherein the intersection of the branches defines an ostium having a three-dimensionally curvilinear shape. A balloon catheter is tracked along the second guidewire to a position in the side branch proximate the ostium. A contoured stent disposed about the balloon includes a proximal end that defines a curvilinear profile that at least approximately matches the curvilinear shape of the ostium when the stent is deployed in the side branch.

摘要： A stent delivery catheter system for accurately positioning a stent in a bifurcated vessel is disclosed. The system includes a catheter having a terminal portion and distal tip that is placed in a main branch of the vessel proximate the bifurcation. A fixed guidewire is attached to distal tip. A port is defined in the terminal portion of the catheter. The port is aligned with an ostium of a side branch of the bifurcated vessel to allow the passage of a stent delivery device, such as a balloon catheter having a stent crimped thereon, into the side branch. Radiopaque bands are positioned on opposite ends of the port. A positioning balloon is included on a surface of the catheter opposite the port and is selectively inflatable to position the radiopaque bands adjacent the side branch ostium. The radiopaque bands are referenced to place the stent proximate the side branch ostium.

摘要： A bifurcation stent delivery catheter includes a first branch balloon, a second branch balloon adjacent the first branch. A centering balloon is optionally disposed distal of the second branch balloon. The balloons are coupled by a coupling device to a main shaft of a catheter. The coupling device allows axial forces to be transmitted from the main shaft to the balloons while allowing the balloons to rotate axially relative to the main shaft with ease. The coupling device functions as an axial rotational joint. The coupling device can have a flexible tubular member that connects the balloons to the main shaft, the tubular member having a torsional flexibility greater than that of the main shaft. The coupling device can have a tubular wall having a cut extending circumferentially around the tubular wall and protective boot covering the cut. The coupling device can have a wound member that allows the axial rotation.

摘要： A catheter arrangement is described that is arranged to permit a guide wire or other structure to be fed laterally from the region of an expandable working element. The catheter includes an elongate flexible tubular member and an inflatable structure carried by a distal portion of the flexible tubular member. The flexible tubular member has a guide wire lumen and at least one fluid supply lumen that is in fluid communication with the inflatable structure. The inflatable structure includes at least one, and preferably two, inflatable members (which may take the form of balloons). In the case of two inflatable members, the first and second inflatable members are radially spaced about the guide wire lumen such that at least one gap is formed between the inflatable members. With this arrangement, the distal end of a guide wire may be advanced through the guide lumen and out of a side opening such that the guide wire passes laterally between the first and second inflatable members. With such an arrangement, a guide wire passing out of the side opening in the region between the inflatable members can readily be directed into a second branch of a vessel bifurcation while the device is positioned in a first branch.

摘要： A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.
