| 20080255447 | DIAGNOSTIC CATHETER - A diagnostic catheter having both a guidewire lumen and at least one contrast lumen is disclosed. In one embodiment, the contrast lumens allow the user to deliver contrast to a target area within the patient without removing the guidewire. Preferably, a plurality of contrast exit ports are included along the length of the catheter body to evenly and consistently distribute contrast into the blood stream, thereby providing improved visualization during radioscopy. | 10-16-2008 |

| 20080255581 | SHORT SLEEVE STENT DELIVERY CATHETER AND METHODS - A stent delivery catheter comprises a catheter body having a proximal end, a distal end, and a guidewire lumen extending from the distal end to at least part way between the proximal end and the distal end. A balloon is disposed over the catheter body near the distal end, and a stent is positioned over the balloon. The stent has a proximal end, a distal end, and a side opening between the proximal end and the distal end. A side sheath is coupled to the catheter body and has a proximal end, a distal end, and a guidewire lumen extending between the proximal end and the distal end. The proximal end of the side sheath is located between the proximal end of the catheter body and the balloon, and the side sheath exits out of the side opening of the stent. | 10-16-2008 |

| 20110282427 | PARTIALLY CRIMPED STENT - A crimping method that crimps a stent over multiple catheters. The method includes differentially crimping a stent on certain portions of a balloon catheter so that a second catheter can be threaded through the uncrimped portion of the stent and exit through the links of a conventional stent design or through a specific hole in the stent designed for a branched vessel. | 11-17-2011 |
