| 20080262601 | Stent Device with Multiple Helix Construction - An improved stent design is disclosed that employs a series of helically oriented expansion elements encircling the stent. Each of the expansion elements includes a stepped pattern employing two distinct pitch angles. The expansion elements are oriented to cooperate with each other to form a series of virtual radially expandable rings that provide suitable outward force for proper stent function, but which are not connected together to form a continuous coherent ring if separated from the stent as a whole. In this manner, a distinctive stent design is provided that has numerous functional benefits over stents described in the prior art. | 10-23-2008 |
| 20080281393 | Bioabsorbable Self-Expanding Endolumenal Devices - The present invention is directed to bioabsorbable self-expanding medical devices for use inside or outside body conduits that self-expand at, or below, normal human body temperature without requisite for a polymeric thermal transition. | 11-13-2008 |
| 20090076587 | Stented Vascular Graft - A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent. | 03-19-2009 |
| 20090088790 | RETRIEVAL CATHETER - A retrieval catheter operable by a single clinician that will neither displace a deployed stent nor cause undue trauma to the vascular lumen or lesion. The retrieval catheter may be sized to accommodate both a guidewire and a balloon wire. The retrieval catheter is easy to navigate through tortuous passageways and will cross a previously deployed stent or stent-graft easily with minimal risk of snagging on the deployed stent or stent graft. The sheath and dilator are adapted to allow a guidewire or balloon wire to pass through the walls of both and to allow the sheath and dilator to move axially with respect to each other. | 04-02-2009 |
| 20090198219 | Catheter Assembly - Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions. | 08-06-2009 |
| 20090259294 | REMOVABLE STENT-GRAFT - A removable device such as a stent-graft, intended for applications where it may be desirable to remove the device at some time following implantation. The stent-graft of the present invention includes a helically-wound stent component provided with a covering of graft material. It is removable by gripping an end of the helically-wound stent component with a retrieval device and applying tension to the stent component in the direction in which it is intended to be withdrawn from the site of implantation. The use of such a retrieval device allows the stent-graft to be removed remotely, such as via a catheter inserted into the body at a different location from the implantation site. The design of the stent-graft is such that the stent component is extended axially while the adjacent portion of the graft separates between windings of the stent component. The axial extension of the stent component, with portions of the graft still joined to the stent component, allows the device to be “unraveled” (or “unwound”) and removed through a catheter of diameter adequately small to be inserted into the body cavity that contained the stent-graft. It is removed atraumatically, without incurring significant trauma to the body conduit in which it had been deployed. | 10-15-2009 |
| 20100011976 | Method of Producing Low Profile Stent and Graft Combination - Large diameter self-expanding endoprosthetic devices, such as stents and stent grafts for delivery to large diameter vessels, such as the aorta, are disclosed having very small compacted delivery dimensions. Devices with deployed dimensions of 26 to 40 mm or more are disclosed that are compacted to extremely small dimensions of 5 mm or less, enabling percutaneous delivery of said devices without the need for surgical intervention. Compaction efficiencies are achieved by combining unique material combinations with new forms of restraining devices, compaction techniques, and delivery techniques. These inventive devices permit consistent percutaneous delivery of large vessel treatment devices. Additionally, small endoprosthetic devices are disclosed that can be compacted to extremely small dimensions for delivery through catheter tubes of less than 1 mm diameter. | 01-21-2010 |
| 20100049293 | Controlled deployable medical device and method of making the same - Controlled deployable medical devices that are retained inside a body passage and in one particular application to vascular devices used in repairing arterial dilations, e.g., aneurysms. Such devices can be adjusted during deployment, thereby allowing at least one of a longitudinal or radial re-positioning, resulting in precise alignment of the device to an implant target site. | 02-25-2010 |

| 20100228262 | ATRAUMATIC LEAD REMOVAL SHEATH - The present invention is an implantable device for the atraumatic removal of chronically implanted medical devices. | 09-09-2010 |
| 20100331956 | ENDOLUMINAL EXPANSION SYSTEM - An endoprosthesis expansion system having, in combination, a delivery component such as a length of catheter tubing having at its distal end an intermediate sheath component, and an inner tube within the full length of the delivery catheter and intermediate sheath component. The inner tube has a protrusion affixed to its distal end, and an expandable endoprosthesis is fitted in a compacted state about the intermediate sheath, immediately proximal to the protrusion. If the endoprosthesis is a self-expanding endoprosthesis (as is preferred), an exterior constraining sheath is required around the outer surface of the endoprosthesis. Following insertion of the endoprosthesis and delivery system into a body conduit (such as a blood vessel) and transport of the endoprosthesis to the desired site within the body conduit, the endoprosthesis is deployed by axially moving the protrusion against the system, thereby applying a radially directed outward force and causing simultaneous dilatation of the intermediate sheath and disruption of the exterior constraining sheath. Disruption of the exterior constraining sheath, in the case of a self-expanding prosthesis, releases the stored energy in the formerly constrained prosthesis, allowing it to expand and accomplish full deployment against the luminal surface of the body conduit at the desired site. | 12-30-2010 |
