The techniques of this disclosure generally relate to an assembly including a single branch stent device and a modular stent device configured to be coupled to the single branch stent device. The single branch stent device includes a main body and a branch coupling extending radially from the main body. The modular stent device includes a main body configured to be coupled inside of the main body of the single branch stent device, a bypass gate extending distally from a distal end of the main body of the modular stent device, and an artery leg extending distally from the distal end of the main body of the modular stent device.

The invention generally relates to co-axial stent and catheter systems and medical procedures utilizing these systems. The co-axial stent system is characterized by two-coaxial stents, including an outer resorbable stent and an inner metal stent used to effect deployment of the resorbable stent. The stents may use for treatment of unstable plaque and/or thrombus at the carotid bifurcation and particularly those that are not causing any significant stenosis. The stents may also be used for treatment of cerebral aneurysms. The invention further describes related, equipment, uses and kits for the treatment of unstable plaque and/or thrombus and/or aneurysms.

A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

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.

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.

A primary stent-graft is deployed into a primary vessel to exclude an aneurysm. To maintain perfusion to a branch vessel covered by the primary stent-graft, a gutter filling stent-graft is deployed in parallel to the primary stent-graft. The gutter filling stent-graft includes a balloon that is pressurized and inflated by the patient's own blood thereby sealing any gutters formed around the gutter filling stent-graft. By sealing the gutters, the chance of type I endoleaks, migrations, and overall failure to exclude the aneurysm is minimized.

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.

A medical implant (20) includes first and second ring members (22, 24), each including a resilient framework (26) having a generally cylindrical form. A tubular sleeve (28) is fixed to the first and second ring members so as to hold the ring members in mutual longitudinal alignment, thereby defining a lumen (32) passing through the ring members. A constricting element (30) is fit around the sleeve at a location intermediate the first and second ring members so as to reduce a diameter of the lumen at the location.

An implantable device includes an outer tubular member defining a longitudinal axis and a lumen. The outer tubular member includes: an outer wall portion having a plurality of first strands defining a plurality of first openings therebetween, the outer wall portion having a first porosity; and an inner baffle portion disposed within the lumen, the inner baffle portion including a plurality of second strands defining a plurality of second openings therebetween, the inner baffle portion having a second porosity that is lower than the first porosity of the outer wall portion.

An apparatus includes a first stent graft that is at least partially insertable into a first blood vessel. The first stent graft has a first end, a second end, an inside surface, and an outside surface. The apparatus also includes an inflatable fill structure fixed to a portion of the outside surface of the first stent graft. The inflatable fill structure includes an outer membrane that is configured to extend beyond the first end of the first stent graft when the inflatable fill structure is in a filled state.
