Abstract:
A thermal insulation product includes infrared radiation absorbing and scattering material dispersed on a loose fill. The infrared absorbing material can include borates, carbonates, nitrates and nitrites of alkali metals and alkaline earth metals.
Abstract:
A system for aiding implantation of a stented valve includes a delivery device and an outer balloon carried upon the delivery device. Additionally, the system includes a first inner balloon positioned within the outer balloon, a second inner balloon positioned within the outer balloon and adjoining the first inner balloon, and at least a first controller operable to introduce and remove fluid from each of the first inner balloon and second inner balloon.
Abstract:
A rotational drilling guidewire includes an elongate body portion and a drilling portion. The drilling portion has multiple cutting elements and is sized to bore an opening having a diameter substantially the same as that of the elongate body portion. A system for treating a vascular condition includes a rotational drilling guidewire and a rotator. The rotator is capable of rotating the guidewire at speeds greater than can be achieved by manual rotation of the guidewire. A method of treating an occluded vessel comprises delivering a guide catheter adjacent to an occlusion, passing a drilling guidewire through the guide catheter to a position abutting the occlusion, rotating the guidewire to bore an opening the same diameter as the guidewire through the occlusion.
Abstract:
A system for treating a vascular condition, including a hollow guidewire, a core wire inserted through the hollow guidewire, and an embolic containment device. The core wire includes a tapered undulating section carried within the hollow guidewire. The embolic containment device is coupled between a distal end of the hollow guidewire and a distal end of the core wire. The tapered undulating section of the core wire provides frictional control of the embolic containment device based on a direction of core wire translation within the hollow guidewire. A method of treating a vascular condition and a guidewire-based embolic filter system are also disclosed.
Abstract:
A guiding catheter for providing proximal occlusion while intubating a branch vessel lumen in a patient. The catheter comprises an elongate hollow shaft having open proximal and distal ends and a resiliently compressible occluder fixed about the shaft adjacent the distal end, the occluder having a relaxed shape that tapers distally from a major diameter greater than a diameter of the vessel lumen. The occluder may comprise elastic foam material or an impermeable flexible cover clingingly enclosing a resilient support member.
Abstract:
A medical device for use in conjunction with magnetic resonance imaging includes a frame which is selectively coupleable to a surface for supporting a patient, and a receiving member for receiving a body member of the patient, usually a hand or a foot of the patient. The receiving member is coupled to the frame such that the it may move relative to the frame along an axis. A moveable member is also coupled to the frame such that it may move relative to the frame along the axis and a spring member is coupled between the moveable member and the receiving member so that the displacement of the moveable member relative to the receiving member is proportional to a component of a force exerted against the receiving member in a direction parallel to the axis. An indicator for indicates the force applied to the receiving member and, consequently, to the joint. All of the elements of the device are comprised of nonmagnetic materials.
