| 20090018502 | Adjustably Stiffenable Convertible Catheter Assembly - A stiffenable balloon catheter assembly capable of being converted from an “over-the-wire” mode with respect to a guidewire extending therethrough to a “rapid-exchange” mode with respect to a guidewire extending therethrough, and vice versa. The catheter has a plurality of lumens, one lumen however, having a side opening with an obstructable galp, the orientation of which, determines the utilization “mode” of the catheter assembly. Stiffening stylets may be adjustably locked into the lumens, depending upon the “mode”, to control the stiffness of the catheter assembly during its utilization within a patient. | 01-15-2009 |
| 20090149808 | Rapid Exchange Balloon Catheter and Method for Making Same - A rapid exchange balloon catheter having a proximal end and a distal end, said catheter comprising: a tubular metal shaft body extending from the proximal end along a majority of the total length and having an inflation lumen arranged therein, a plastics distal end portion bonded to the metal body in extension thereof, said distal end portion being provided with an inflation lumen in communication with a balloon, and a guide wire lumen, said guide wire lumen extending from a proximal side port to a distal end opening.

| 20100094211 | Balloon Catheter with Improved Pushability - Rapid exchange angioplasty catheters and methods of constructing rapid exchange angioplasty catheters including features that provide good pushability and kink resistance. In an illustrative embodiment, a catheter is provided, the illustrative catheter including a proximal hypotube section, which connects to a more distal braided catheter section. The braided catheter section connects to a midshaft portion that includes a guidewire entry port. Distal of the midshaft portion is a distal section having a balloon disposed thereon. An inflation lumen extends the length of the catheter, while a guidewire lumen extends only from the guidewire entry port to the distal end of the catheter. Optionally, a core wire may extend across the joint from the hypotube, to the braided catheter section, and past the guidewire entry port. | 04-15-2010 |
| 20120004606 | REINFORCED RAPID EXCHANGE CATHETER - A medical balloon catheter including a shaft comprised of a cross-wound coil tube and a sleeve surrounding the cross-wound coil tube. The cross-wound coil tube includes a monofilament inner coil disposed within a monofilament outer coil. The inner and outer coils are wound in opposite pitch directions. In at least one embodiment, at least one of the inner and outer coils includes a tapered distal section having a tapered diameter. In at least another embodiment, the inner coil extends distally beyond the distal end of the outer coil, providing increased flexibility in a distal portion of the shaft. An inflation balloon is attached to the distal end of the shaft. The shaft includes an inflation lumen formed through the inner coil and a wire guide lumen formed through the distal portion of the shaft and extending through the chamber of the balloon. | 01-05-2012 |

| 20130041316 | CATHETER WITH DISRUPTABLE GUIDEWIRE CHANNEL - The present invention is a catheter device that includes a disruptable guidewire channel. The guidewire channel is configured to provide necessary trackability of the catheter along the guidewire during introduction of the catheter to a treatment site.
