ILIAC BRANCH DEVICE AND METHOD
20170296324 · 2017-10-19 ·

An iliac branch device includes an iliac septum limb configured to be deployed in the common iliac artery. The iliac septum limb includes a graft material, a proximal end, and a septum. The graft material defines a common iliac lumen extending between the proximal end and the septum, the graft material and the septum defining an internal iliac lumen and an external iliac lumen. The iliac branch device including the iliac septum limb has several modes of adjustability. In addition, the iliac branch device has a relatively small cross-sectional area allowing the iliac branch device to treat relatively small iliac aneurysms in short common iliac arteries. This allows the iliac aneurysms to be treated at very early stages of the disease.

Advanced endovascular graft

This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

Methods and systems for establishing retrograde carotid arterial blood flow

Interventional procedures on the carotid arteries are performed through a transcervical access while retrograde blood flow is established from the internal carotid artery to a venous or external location. A system for use in accessing and treating a carotid artery includes an arterial access device, a shunt fluidly connected to the arterial access device, and a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. The flow control assembly includes one or more components that interact with the blood flow through the shunt.

Medical device delivery system and deployment method

An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D−24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.

Methods and devices for intracorporeal bonding of implants with thermal energy

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

ROTATIONAL SPUN MATERIAL COVERED MEDICAL APPLIANCES AND METHODS OF MANUFACTURE

A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.

ENDOLUMINAL PROSTHETIC DEVICES HAVING FLUID-ABSORBABLE COMPOSITIONS FOR REPAIR OF A VASCULAR TISSUE DEFECT

Endoluminal prosthetic devices having fluid-absorbable compositions for repair of vascular tissue defects, such as an aneurysm or dissection, are disclosed herein. A prosthesis for repairing an opening or cavity within a target vessel region configured in accordance herewith includes a tubular body sized to substantially cover the opening or cavity, and having channels formed in a wall thereof. The channels can include a fluid-absorbable composition deposited therein and which is configured to absorb fluid (e.g., blood) and swell within the channels, thereby providing radial expansion of the tubular body in situ.

STENT GRAFT SYSTEMS AND METHODS WITH INFLATABLE FILL STRUCTURE AND FILLABLE CUFF

A stent graft system includes a stent graft an inflatable fill structure, and a cuff. The inflatable fill structure at least partially surrounds the stent graft. In various arrangements, the inflatable fill structure has a cavity that is bifurcated. A portion of the cavity is configured to receive a branch stent graft for connection to the stent graft. The cuff is fillable and is located outside of the inflatable fill structure, and allows for providing a seal with a wall of a blood vessel. The cuff and the inflatable fill structure are separately fillable from each other to different pressures with fill medium. In various arrangements, the cuff has a tapered shape such that it is wider at one end than at an opposite end when filled with a fill medium. A method includes filling the cuff to a higher pressure than a pressure of the inflatable fill structure.

Lumen Stent and Implant

A lumen stent (100) and an implant are provided. The lumen stent includes a tubular body (11), an inner branch (12) and an outer branch (13) which are respectively communicated with the tubular body (11). The tubular body (11) includes a first body segment (111), a tapered segment (112) and a second body segment (113) which are connected in sequence. The tapered segment (112) is provided with an outer branch window (110b) and an inner branch window (110a). The proximal end of the outer branch (13) is connected to the outer branch window (110b). The distal end of the inner branch (12) is connected to the inner branch window (110a). The area of the inner branch window (110a) is larger than that of the outer branch window (110b). The beneficial effects are as follows: since the area of the inner branch window (110a) is larger than that of the outer branch window (110b), most of blood flow can rapidly pass through the inner branch (12), so that the blood flow pressure of the outer branch (13) is reduced, and the distal end of the outer branch (13) is prevented from tilting and touching an inner wall of a tumor cavity.

Stent with a crush-resistant zone

An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft with coupling portion disposed in the fenestration of the fenestrated stent graft.
