| 20080208329 | HANDLE MECHANISM TO ADJUST A MEDICAL DEVICE - An apparatus for adjusting the position and orientation of a medical device within a patient's body includes a distal portion, a body portion and a proximal portion. The distal portion has a lumen for receiving at least three control tubes. Each control tube houses a control wire that is attached to the medical device. The body portion is connected to the distal portion by a ball-and-socket joint and configured to receive at least one control wire. The proximal portion is rotatably and slidably attached to the body portion and configured to receive at least one control wire. | 08-28-2008 |
| 20100274187 | Centering for a TAA - A stent graft is deployed by a steerable catheter delivery system having a integral tip capture release mechanism. The steering mechanism provides for a locked interference with a distal lock at the distal end of the delivery catheter. The configuration allows for selective circumferentially distributed release of one half or less of the number of crowns of a proximal spring which are captured by a tip capture mechanism so that new positioning of the stent graft can be verified and assured before full release of all proximal spring crowns is done. In this way, one or more steering elements of a catheter can be maintained in tension until catheter position is verified and acceptable stent graft position is achieved. This apparatus and method is particularly useful for deploying stent graft in curved passages such a thoracic aorta. | 10-28-2010 |
| 20110251665 | Delivery System Ejection Component and Method - A stent or stent-graft delivery system includes a stent ejection component. The stent ejection component includes a body and an ejection collar. The ejection collar extends from the body in the proximal direction. The ejection collar assists in automatically ejecting a proximal end of a stent when the tapered tip is moved in the distal direction to deploy the stent. A stent or stent-graft delivery system may also include a retain-sleeve landing component. The retaining-sleeve landing component includes a body and a landing collar. The landing collar extends from the body in a distal direction. The landing collar automatically captures a tapered tip of the delivery system when the tapered tip is moved in a distal direction to deploy a stent contained in the delivery system. Upon capture of the tapered tip, the stent ejection component with the tapered tip attached has an atraumatic profile. | 10-13-2011 |

| 20110251667 | Anchor Pin Stent-Graft Delivery System - A stent-graft delivery system includes a stent-graft including a proximal anchor stent ring. The proximal anchor stent ring includes proximal apexes and anchor pin structures extending proximally from each of the proximal apexes. The anchor pin structures include anchor pin connecting arms and anchor pins. The anchor pin structures are tucked together to accommodate small catheter sizes. Further, the anchor pins reduce or eliminate migration of the stent-graft. Further still, the anchor pin connecting arms are long and flexible thus distributing stresses in a way that improves the load carrying capacity of the anchor pins and allows flowering of the graft material of the stent-graft prior to release of the anchor pins structures. | 10-13-2011 |
| 20110257718 | Retraction Mechanism and Method for Graft Cover Retraction - A stent or stent-graft delivery system includes a handle having a graft cover retractor having a screw gear and a drive and quick release assembly. The drive and quick release assembly includes a proximal portion and a distal portion that are separable. The proximal portion of the drive and quick release assembly rotates in a first rotational direction about the screw gear to retract the graft cover using the screw gear. The drive and quick release assembly transitions from retraction using the engagement with the screw gear to retraction by sliding by the user grasping the distal portion instead of the proximal portion, and sliding the proximal portion only along the screw gear. In transitioning from using the screw gear to sliding along screw gear, it unnecessary to push any button and unnecessary for the user to remove her/his hand from the assembly. | 10-20-2011 |
| 20110257719 | Retraction Mechanism and Method for Graft Cover Retraction - A stent or stent-graft delivery system includes a handle having a graft cover retractor having a screw gear and a drive and quick release assembly. The drive and quick release assembly allows a user to retract a graft cover by rotating the assembly in a first rotational direction about the screw gear. When the assembly is being rotated in a particular rotational direction, a partial revolution in the opposite rotational direction disengages the assembly from the screw gear, which is sensed by a change in the force required to rotate the assembly. With the assembly disengaged from the screw gear, the assembly can be slid along the screw so that the graft cover can be positioned more quickly. In transitioning from using the screw gear to sliding along screw gear, it unnecessary to push any button and unnecessary for the user to remove her/his hand from the assembly. | 10-20-2011 |
| 20110257725 | Blood Inflating Prosthesis - A prosthesis comprises a tubular member that defines an inner lumen and has an inner surface and an outer surface, an outer member secured to the tubular member and covering at least a portion of the tubular member outer surface and forming an outer chamber therewith, and at least one valve in the tubular member to regulate or control fluid flow between the tubular member lumen and the chamber. | 10-20-2011 |
