20080208311 | MULTIPLE INDEPENDENT NESTED STENT STRUCTURES AND METHODS FOR THEIR PREPARATION AND DEPLOYMENT - Blood vessels and other body lumens are stented using stent structures comprising a plurality of radially expansible rings where at least some of the rings comprise axially extending elements which interleave with axially extending elements on adjacent unconnected rings. The ring structures may be open cell structures or closed cell structures, and the axially extending elements will typically be formed as part of the open cell or closed cell structure. | 08-28-2008 |
20090149863 | FIXED STENT DELIVERY DEVICES AND METHODS - Stent delivery devices and methods include multiple stents or stent segments mounted at fixed positions on an expandable member of the stent delivery catheter. One or more of the fixed-position stents may be selectively deployed in a body lumen such as a blood vessel by positioning one or more sheaths to constrain some stents while exposing others for deployment. Some embodiments include two axially movable sheaths for serially deploying stents while containing a portion of the expandable balloon from which stents have been deployed. Other embodiments include inner and outer balloon shafts to allow the balloon to be retracted into the delivery catheter as stents are deployed. Devices and methods of the invention provide enhanced serial deployment of multiple stents or stent segments while reducing the risk of damage to an expandable deployment member. | 06-11-2009 |

20100292733 | KNOTLESS SUTURE ANCHOR AND METHODS OF USE - Various devices, systems and methods for knotless suturing of tissue are disclosed. These devices allow sutures to be anchored to bone, and more specifically provide a suture anchor which eliminates the need for knotting the suture. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts may be suited to being a single molded polymer construction. The anchors will find particular utility in hip and shoulder arthroscopy, e.g. labral re-attachment and similar procedures. | 11-18-2010 |
20120165930 | SYSTEM FOR MITRAL VALVE REPAIR AND REPLACEMENT - Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets. | 06-28-2012 |
