20100217234 | Catheter With Skived Tubular Member - An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint. | 08-26-2010 |
20110009942 | BALLOON CATHETER - Balloon catheters and stent delivery systems including bifurcated stent delivery systems are disclosed. An example bifurcated stent delivery system may include an elongate shaft including a proximal section, a midshaft section, and a distal section. The proximal section may include a tubular member having a plurality of slots formed therein. The slots may be arranged in one or more sections having differing slot densities. The midshaft section may include a guidewire port in fluid communication with a guidewire lumen formed in the shaft. A main branch balloon may be coupled to the shaft. A side branch balloon may be disposed adjacent to the main branch balloon. A stent may be disposed on the main branch balloon and on the side branch balloon. | 01-13-2011 |

The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint. | 03-08-2012 |
20120239003 | Multiple Guidewire System - Multiple guidewire systems and methods of using are disclosed. In one illustrative embodiment, a guidewire system may include a first guidewire releasably coupled to a second guidewire such that when the guidewire system is advanced through a vessel, the first guidewire may be coupled to the second guidewire. After the guidewire system has been advanced through a vessel, the first guidewire and the second guidewire may be separated. In some instances, the first guidewire may be chemically, mechanically, electrically, and/or mechanically releasably coupled to the second guidewire. | 09-20-2012 |
20120296366 | BALLOON CATHETER WITH IMPROVED PUSHABILITY - Balloon catheter and methods for making and using balloon catheters are disclosed. An example balloon catheter may include a proximal shaft. A midshaft may be attached to the proximal shaft. The midshaft may have an outer wall. A distal shaft may be attached to the midshaft. A balloon may be coupled to the distal shaft. An inflation lumen may be defined that extends from the proximal shaft, through the midshaft, and into the distal shaft. The inflation lumen may be in fluid communication with the balloon. A core wire may be disposed within the inflation lumen and may be attached to the midshaft. | 11-22-2012 |
20120296367 | BALLOON CATHETER WITH IMPROVED PUSHABILITY - Balloon catheter and methods for making and using balloon catheters are disclosed. An example balloon catheter may include a proximal shaft. A midshaft may be attached to the proximal shaft. A distal shaft may be attached to the midshaft. A balloon may be coupled to the distal shaft. An inflation lumen may be defined that extends from the proximal shaft, through the midshaft, and into the distal shaft. The inflation lumen may be in fluid communication with the balloon. A core wire may extend through a portion of the inflation lumen. The midshaft may define an interior ridge along a portion of the inflation lumen. The core wire may have a shoulder that abuts the interior ridge of the midshaft. | 11-22-2012 |
