International Classification:

US Classification:

623/001530, 623/001150, 623/903000

Abstract:

An intraluminal device implantable in a blood vessel having an aneurysm therein in the vicinity of a perforating vessel and/or of a bifurcation leading to a branch vessel. The intraluminal device includes a mesh-like tube of bio-compatible material having an expanded condition in which the tube diameter is slightly larger than the diameter of the blood vessel in which it is to be implanted, and the tube length is sufficient to straddle the aneurysm and to be anchored to the blood vessel on the opposite sides of the aneurysm. The mesh-like tube also has a contracted condition wherein it is sufficiently flexible so as to be easily manipulatable through the blood vessel to straddle the aneurysm. In its expanded condition, the mesh-like tube has a porosity index of 55%-80% such as to reduce the flow of blood through its wall to the aneurysm sufficiently to decrease the possibility of rupture of the aneurysm but not to unduly reduce the blood flow to a perforating or branch vessel to the degree likely to cause significant damage to tissues supplied with blood by such perforating or branch vessel.

International Classification:

A61M 29/00

US Classification:

606191

Abstract:

A method and device for occluding an aneurysm. The device may include a wire having a shape memory. The wire may define a coil. The wire may further define a first substantially spherical helix and a second substantially spherical helix nested within the first substantially spherical helix. A catheter may be included, being releaseably engageable to the wire, the wire being at least partially disposed within the catheter.

International Classification:

G06G 7/48

US Classification:

703 6

Abstract:

A system, method, computer-readable medium, apparatus, and device for simulating placement of an expandable device in a cavity is provided. For example, a three or more dimensional image of a cavity, e.g., a tubular cavity, geometry is acquired. A centerline of the cavity, and a perimeter of the cavity based on the centerline of the cavity and the three-dimensional image of the cavity geometry, are determined. The length of a wire of the expandable device as the wire rotates along the perimeter of the cavity in a deployment direction is determined. A pitch of the rotation of the wire based on a local diameter at the centerline site of rotation and in-air parameters of the expandable device is determined. A deployed device length of the expandable device along the centerline of the cavity is determined. A processor is usable to determine and/or calculate each of the above.

International Classification:

US Classification:

434265, 434268

Abstract:

The present invention describes a device and system for simulating normal and disease state cardiac functioning, including an anatomically accurate left cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart. Through the use of a remote handheld electronic controller and manual adjustments from a main control panel, the air pressure level, fluidic pressure, and heart rate is controlled to induce contractions that simulate a wide variety of heart conditions ranging from normal heart function to severely diseased or injured heart conditions.
