| 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 |
| 20100286756 | Catheter Device - A catheter device having a shaft that extends from a proximal end to a distal end to carry on its distal end a self-expanding implant for intraluminal advance on a guidewire and delivery of the implant to an implant site by proximal withdrawal of a sheath that lies radially outside the implant in the catheter, the catheter including a first shaft element to pull the sheath proximally and a second shaft element to push the implant distally to prevent the implant moving proximally with the sheath when the sheath is pulled proximally, wherein the second shaft element carries a stopper for abutting the implant, the stopper comprising proximal and distal portions having different radiopacities. | 11-11-2010 |
| 20110060397 | METHOD OF LOADING A STENT INTO A SHEATH - There is disclosed herein a method of loading a self-expanding stent ( | 03-10-2011 |
| 20110137396 | STENT DEVICE DELIVERY SYSTEM WITH INWARDLY TAPERING STENT BED - A stent device delivery system and method of making. The stent device delivery system includes a stent device, an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, and an inner catheter extending axially and radially within a lumen of the stent device. The inner catheter provides a stent bed upon which the stent device is located so that a radially inner surface of the stent device engages a radially outer surface of the stent bed. The stent bed may define an inwardly tapering profile, narrowing in radius from a distal portion of the stent device to a proximal portion of the stent device. | 06-09-2011 |
| 20110137400 | STENT DEVICE DELIVERY SYSTEM WITH A VARYING RADIAL PROFILE PULL MEMBER - A stent device delivery system and method of making. The stent device delivery system includes a stent device, an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, and a pull member. The outer sheath may include a first layer and a reinforcement layer that are laminated together, a portion of the pull member captured radially between the first layer and the reinforcement layer. At least a partial length of the captured portion of the pull member may be formed with a varying radial profile. | 06-09-2011 |
| 20110137401 | STENT DEVICE DELIVERY SYSTEM WITH AN OUTER SHEATH POLYMERIC REINFORCEMENT LAYER - A stent device delivery system and method of making. The stent device delivery system includes a stent device and an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device.
