The outer sheath may be positioned to ride over the proximal cone of the hot balloon catheter and abut the proximal end of the stent to facilitate proper alignment of the balloon for deployment. Upon deployment of the stent in an appropriate position, the sheath may be pulled away from the stent to expose the proximal cone of the balloon and thereby allow balloon and stent expansion. | 07-16-2009 |
| 20090187238 | SYSTEM AND METHOD FOR DEPLOYING SELF-EXPANDABLE MEDICAL DEVICE WITH COATING - A system and method for providing a coating on a self-expandable medical device such as a stent are disclosed.

| 20090216309 | CONFORMABLE VASCULAR PROSTHESIS DELIVERY SYSTEM - Novel approaches for a conformable vascular prosthesis delivery system are provided which overcome the limitations of existing high pressure balloons for delivering intravascular prostheses to the site of high-risk plaques. One embodiment involves a short balloon segment which is inflated at one end of the prosthesis and then pulled to traverse the length of the prosthesis, dilating the surrounding prosthesis and securing it to the vessel wall as it traverses the length of the prosthesis. The short balloon segment causes less local trauma to the vessel relative to a full length balloon. Another embodiment involves use of a self-expandable mesh to expand the surrounding prosthesis and secure it to the vessel wall. The self expandable mesh is less traumatic than a typical angioplasty balloon because of the lower radial forces applied and the relatively higher transverse flexibility of the mesh. | 08-27-2009 |

However, as the central low metal to vessel ratio zone is highly permeable, blood flows from the main vessel through the central low metal to vessel ratio zone and into branch vessels. | 10-03-2013 |
| 20130261728 | HIGH METAL TO VESSEL RATIO STENT AND METHOD - A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with a high metal to vessel ratio stent. A metal to vessel ratio of the high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the high metal to vessel ratio stent. The ingrowth of tissue provides secure fixation and sealing of the high metal to vessel ratio stent to the main vessel and remodels and essentially eliminates the aneurysm. Further, as the entire high metal to vessel ratio stent is permeably, the high metal to vessel ratio stent is deployed without having to rotationally position the high metal to vessel ratio stent. | 10-03-2013 |
