摘要： Systems and methods for treating a tissue region employ an expandable structure projecting beyond the distal end of a catheter tube. A distal tail projects beyond the far end of the basket assembly. The distal tail includes a guidewire lumen that accommodates passage of a guidewire without threading the guidewire through the catheter tube.

摘要： An improved catheter assembly and method are provided for delivering guide wires to vessels. The catheter assembly of the present invention has the feature of containing two guide wire lumens in a single catheter to prevent wire wrapping and crossing of the wires. A torquing member is provided to assist in rotation of the catheter. The assembly allows for the delivery of a wire into a side branch vessel that is at a steep angle with respect to a main vessel. The assembly also provides for the delivery of two guide wires to a bifurcation.

摘要： A method and kit for accessing the pericardial space take advantage of the fact that the right auricle is a thin-walled, low-pressure structure which can be readily penetrated without damaging the pericardium or the epicardium. The method includes the step of passing a guide catheter through a selected peripheral vein to establish a transvenous route to the right auricle of the heart. An infusion guide wire and a leading guide wire are passed through the guide catheter and into the right auricle so that a distal end of the leading guide wire is positioned against a wall of the right auricle. The leading guide wire is located within a lumen of the infusion guide wire and protrudes outward, preferably about 2 mm, from a distal end of the infusion guide wire. The wall of the right auricle is then pierced with the distal end of the leading guide wire. After the wall of the right auricle is pierced, at least one of the infusion guide wire and the leading guide wire are advanced into the pericardial space. Once in position, the infusion guide wire and/or the leading guide wire can be used as a conduit over which a desired catheter may be introduced for performing a specific medical procedure. Alternatively, the infusion guide wire and/or the leading guide wire can be used to perform a specific medical procedure without the introduction of an additional device into the pericardial space.

摘要： Catheter for use in biliary procedures, including a shaft having a proximal end and a distal end. A guidewire lumen is carried by the shaft extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft. An opening is included for accessing the guidewire lumen from a location exterior the catheter shaft located distal the proximal end of the shaft. The guidewire lumen may be formed integral the catheter shaft. The catheter may be used in rapid exchange catheter procedures. The catheter may further include a port and channel design including a first opening into the guidewire lumen located proximal the distal end of the shaft, a second opening located proximal the first opening, and a channel extending longitudinally between the first opening and the second opening.

摘要： A catheter system for use during biliary procedures, including a first elongate member carrying a guidewire lumen, and a channel extending longitudinally along the member which provides access to the guidewire lumen and defines two edge surfaces. A second elongate member is also included which is disposed within the guidewire lumen and mates with the cross-sectional profile of the guidewire lumen of the first elongate member, thereby converting a guidewire lumen having a C-shaped design into one having an O-shaped design. The catheter may be used in rapid exchange catheter procedures requiring the use of small diameter guidewires which would otherwise slip out of the channel during use.

摘要： A handle includes a body portion and a handle portion which is slidably and rotatably mounted on the body portion. Shoulders on the body portion and the handle portion limit relative sliding movement of the body portion and handle portion. A catheter open at both ends has one end fixed to the handle portion for movement therewith, the opposite end of the catheter having a shape memory tip. A fitting is threadedly connected to an enlarged part of the body portion. A sheath is threadedly connected to the fitting and the catheter is slidable and rotatable within the sheath. An annular channel is provided between the sheath and the catheter, this channel being in fluid communication with a bore in the fitting. The outer end of the sheath has holes therethrough in fluid communication with the channel. An irrigation inflow and aspiration outflow tube is also in fluid communication with the bore in the fitting. A first lock is provided adjacent the fitting for controlling the amount of frictional resistance to lengthwise movement of the catheter relative to the sheath and to lock the catheter in position. A medical device such as an endoscope may be received within the catheter for movement relative thereto. A second lock is supported by the handle portion for locking a medical device in position relative to the catheter.

摘要： A catheter for use with a guidewire, the catheter having a distal tip that centers the guidewire even when the catheter is severely bent, thereby avoiding protrusion of the distal tip of the catheter at the outer meridian of the catheter bend and reducing the risk of the catheter tip catching on the luminal surface of the adjacent vasculature. The distal tip of the catheter incorporates at least one guidewire bearing, preferably multiple bearings in the form of longitudinally oriented ribs, which provide the centering characteristic with minimal friction between the inner surface of the catheter distal tip and the outer surface of the guidewire. Preferably, at least four guidewire bearings are provided.

摘要： A rapid exchange catheter comprises a guide wire lumen including a substantially sealed portion in which a lumen wall extends around an entire periphery thereof and a channel portion including a channel opening the lumen to an exterior of the catheter, wherein a width of the channel is less than a maximum width of the channel portion. A guide wire ramp extends into the channel portion, with the ramp extending further into the lumen of the channel portion as a distal end of the ramp is approached.
