20090157160 | APPARATUS AND METHODS FOR PROTECTED ANGIOPLASTY AND STENTING AT A CAROTID BIFURCATION - Apparatus and methods are described for performing protected angioplasty and stenting of a patient's carotid bifurcation. An integrated catheter system can be configured in a rapid-exchange version or in an over-the-wire version. The catheter system includes a self-expanding stent, a stent delivery sheath, a combination angioplasty balloon catheter and stent pusher catheter, an embolic protection device and, in the rapid-exchange version, an auto-releasing sheath. The method includes: inserting a guiding catheter to the carotid bifurcation; inserting the catheter system through the guiding catheter; advancing the embolic protection device beyond the lesion; positioning the stent and balloon segment of the catheter system at the lesion; releasing the self-expanding stent; pulling the stent delivery sheath back into the guiding catheter; positioning and deploying the protection member; advancing the combination angioplasty balloon catheter and stent pusher catheter and inflating the angioplasty balloon within the lesion; deflating the angioplasty balloon and withdrawing the combination angioplasty balloon catheter and stent pusher catheter and stent delivery sheath together; and aspirating potential emboli through the guiding catheter. | 06-18-2009 |

20100174352 | Catheter system for angioplasty and stenting with embolic protection - Apparatus and methods are described for performing angioplasty and stenting with embolic protection. A catheter system includes an angioplasty balloon catheter, a balloon-expandable stent, an embolic protection device and a linking device. The catheter system has an undeployed configuration in which the balloon-expandable stent is mounted on the inflatable angioplasty balloon in an uninflated condition, the embolic protection member is positioned distally to the balloon-expandable stent and the angioplasty balloon, and the linking device is mounted on the catheter shaft of the angioplasty balloon catheter and the device shaft of the embolic protection device. The linking device prevents any relative longitudinal motion of the angioplasty balloon catheter and the embolic protection device, which might lead to accidental dislodgement of the balloon-expandable stent. | 07-08-2010 |
20110112626 | BIORESORBABLE VASCULAR IMPLANT HAVING HOMOGENOUSLY DISTRIBUTED STRESSES UNDER A RADIAL LOAD - A bioresorbable vascular implant for implantation in a bodily lumen has a tubular framework and includes one or more annular support members. Each of the one or more annular support members includes a plurality of struts interconnected by a hinge region. Each of the plurality of struts also includes a mid-section. The vascular implant also includes at least one viscoelastic material that enables transition of the vascular implant between a collapsed configuration and an expanded configuration. Each of the plurality of struts and the hinge region defines a cross-section. The moment of inertia increases from the mid-section towards the hinge region to accommodate the transition and resist a radial load applied to the vascular implant in the expanded configuration. | 05-12-2011 |
