    摘要： Implantable therapeutic devices and methods for endovascular placement of devices at a target site, such an opening at a neck of an aneurysm, are disclosed. Selected embodiments of the present technology have closures (102) that at least partially occlude the neck of an aneurysm to stabilize embolic or coagulative treatment of the aneurysm. In one embodiment, for example, an aneurysm closure device comprises a closure structure (102) and a supplemental stabilizer (103). The closure structure can have a curved portion configured to extend along a first vessel, such as a side branch of a bifurcated vessel that extends along a lateral axis (T). The supplemental stabilizer extends from the closure structure along a longitudinal axis (L) transverse to the lateral axis of the first vessel. The supplemental stabilizer is configured to exert an outward force against a second vessel, such as a parent vessel, that extends transversely to the first vessel.

    摘要： A method of treating a neurological disorder in a patient is provided. The method comprises intravascularly delivering a stimulation lead within the head of the patient, and placing the stimulation lead adjacent brain tissue (e.g., cortical brain tissue or deep brain tissue), the stimulation of which will treat the neurological disorder. The stimulation lead can be placed into indirect contact with the brain tissue (e.g., through a blood vessel) or indirect contact with the brain tissue (e.g., when placed within the ventricular cavity or by being introduced through an exit point within a vessel wall). Optionally, the method comprises implanting a source of stimulation within the patient's body, and then electrically coupling the proximal end of the stimulation lead, which conveniently extends from the access point within the circulatory system, to the implanted stimulation source. Using the stimulation lead, the brain tissue can then be stimulated in order to treat the neurological disorder.

    摘要： An improved guiding member for use within a body lumen having a unique combination of superelastic characteristics. The superelastic alloy material has a composition consisting of about 30% to about 52% (atomic) titanium, and about 38% to 52% nickel and may have one or more elements selected from the group consisting of iron, cobalt, platinum, palladium, vanadium, copper, zirconium, hafnium and niobium. The alloy material is subjected to thermomechanical processing which includes a final cold working of about 10 to about 75% and then a: heat treatment at a temperature between about 450° and about 600° C. and preferably about 475° to about 550° C. Before the heat treatment the cold worked alloy material is preferably subjected to mechanical straightening. The alloy material is preferably subjected to stresses equal to about 5 to about 50% of the room temperature ultimate yield stress of the material during the thermal treatment. The guiding member using such improved material exhibits a stress-induced austenite-to-martensite phase transformation at an exceptionally high constant yield strength of over 90 ksi for solid members and over 70 ksi for tubular members with a broad recoverable strain of at least about 4% during the phase transformation. An essentially whip free product is obtained.
