Abstract: The present disclosure is directed to a branched endoprosthesis comprising a graft component and at least one support component. In various embodiments, the branched endoprosthesis comprises a body portion and a plurality of leg portions, wherein the legs are in an aligned configuration for ease of cannulation. In various embodiments, at least one leg is in an open configuration for ease of cannulation. Cannulation methods are also taught.

Abstract: An in-line wire connector has a connector body with two insert ends on opposing ends for receiving a first and a second wire into apertures. A truncated tapered coil is configured within the connector body to secure the first and second wires to the in-line wire connector. The in-line twist on wire connector connects wires in line and may be low profile to allow the wires and the wire connector to slide through apertures and tight spaces as it often required in construction and remodeling projects. An in-line wire connector may have two truncated tapered coils that taper toward the opposing ends. A first and second wire conductor extend past each other toward opposing insert ends to produce an overlap portion to create electrical contact between wires. When the connector body is rotated, the wires rotate about each other and are retained by the tapered coil.

Abstract: 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.

Abstract: An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that slides over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. The sheath may include a window that is aligned with the inlet port when the sheath is moved to open the valve. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.

Abstract: A conduit, such as an introducer sheath, catheter, or guide catheter, incorporating two or more separate lumens to prevent the entanglement of guidewires located at least partially within the conduit. The lumens are separated by at least one disruptable barrier that allows multiple lumens to be converted into fewer lumens prior to or as a device is advanced through the introducer sheath.

Abstract: A radially compliant pressure indicating stent graft is radially compliant from a free stent graft diameter to an expanded stent graft diameter. A radially compliant slant is attached to a graft having stored circumferential length between attachment points. A slant may be expanded and affixed to the graft or the graft may be constricted radially and the stent attached to the constricted graft. The radially compliant stent graft may expand radially to a free graft diameter and the graft may be non-elastic and/or no compliant. As the stent graft approaches the free graft diameter, the force to expand further may increase rapidly.

Abstract: The present disclosure includes an endoprosthesis comprising a descending stent-graft, an ascending stent-graft, and/or a side-branch stent-graft. In various embodiments, an ascending stent-graft is capable of being coupled to a descending stent-graft, and/or a descending stent-graft can comprise a fenestration capable of being coupled to a side-branch stent-graft. In addition, in various embodiments, a descending and/or ascending stent-graft can comprise a reduced diameter portion that, when implanted within an aortic arch, recedes from a luminal surface of the aortic arch to allow a side-branch stent-graft to be maneuvered within the aortic arch.

Abstract: The present disclosure describes a system and method for forming a stent or stent-graft for use in the vasculature of a human patient. The system comprises a mandrel and a collar configured to slide and rotate in relation to the mandrel. The mandrel includes at least one groove that corresponds to the desired shape of a stent or stent-graft. The stent or stent-graft is formed by sliding and rotating the collar along the surface of the mandrel, which forces a wire to conform to the shape of the groove.

Abstract: The present disclosure is directed to an endoprosthesis comprising a graft component and at least one support component with varying compressibility along the length of the endoprosthesis. In various embodiments, the endoprosthesis comprises at least a first segment and a second segment, wherein the first segment is more compressible than the second. In another embodiment having a second segment between the first and third segments, the third segment can also be more compressible than the second segment. Alternatively, in an embodiment, a second segment can have greater rigidity than a first segment, as well as a third segment, if present.
