| 20090281617 | Sleeves for Positioning a Stent on a Delivery Balloon Catheter System - The present invention provides one or more sleeves for positioning a stent on a stent delivery system, such as a balloon catheter. The sleeve wraps around the catheter. One or two sleeves are positioned adjacent to one or both ends of the stent without overlapping with the stent. One end of the sleeve may be attached to the catheter or the balloon. The outer diameter of the end of the sleeve adjacent to the stent may be no greater than the outer diameter of the unexpanded stent. As a result, the profile of the stent delivery system is not increased by the sleeves of the present invention. If the stent dislodges during delivery to the target site, the stent can come to rest on the wall of the sleeve. Because the sleeves are positioned adjacent to the stent without overlapping with the stent, the stent is able to expand without being restrained by the sleeves. In addition, except for the stent, no other component of the stent delivery system, including the sleeves, comes into contact with the vessel wall when the balloon is expanded. This minimizes damages caused by the stent delivery system to the vessel. | 11-12-2009 |

| 20100280596 | IMPLANT DELIVERY DEVICE - Disclosed is a system for delivering self-expanding stents to stenting sites within the body, which minimizes trauma to the affected tissue of the patient yet, at the same time, offers the medical practitioner a robust and simple system for stent placement. These technical effects are achieved by providing a catheter which receives the stent at its proximal end and guides it to the stenting site. The catheter serves as a guide catheter and has a tapered distal tip from which the stent emerges at the site of stenting. A stent pusher can be used which abuts the proximal end of the stent inside the guide catheter. The tapered tip can be molded and can be integral with the catheter shaft or bonded to it. The guide catheter can include a figurated portion towards its distal tip. The system has particular application to stenting the carotid artery. | 11-04-2010 |
| 20100286761 | Translucent Outer Sheath - A transparent outer covering used in a co-axial metallic ureteric stent for deployment of the lower tip of the metallic ureteric stent in relation to the ureteric orifice. Exact positioning of the stent is critical to avoid complications and ensure proper functioning of the stent. Stent is deployed from within outer sheath in a coaxial system. The function of the coaxial outer sheath is to provide a straight channel for deployment and positioning of the curl-tipped metal stent (double-J stent). Without the outer sheath it would simply not be possible to advance the flexible, curl-tipped metal stent into the kidney. Surgeon controls a ureteric catheter ‘pusher’ whose tip is advanced against the lower tip of the metal stent within the OPAQUE sheath, Deployment is achieved by withdrawing the OPAQUE outer sheath, while holding stent/ureteric catheter in static position. The lower tip of the metal stent must be deployed between the bladder neck and the ureteric orifice which are soft tissue structures and therefore not visible on flouroscopy. The surgeon absolutely requires direct visualization of the lower tip of the stent to see its relation to these landmarks. The existing outer deployment sheath is opaque. Converting outer deployment sheath to translucent would thereby substantively improve deployment accuracy of stent and avoid complications of deployment above ureteric orifice or below bladder neck. | 11-11-2010 |
