Abstract
The invention features intravascular devices, in particular devices for deflecting emboli (100), and elements for connecting such devices to wires. Such connecting elements are configured to limit within a range the relative rotation between device and wire.
Claims30
An intravascular device comprising a first wire, a second wire, and a connecting element;
- wherein:
- a. said connecting element comprises a hollow cylindrical body defining an internal channel along a longitudinal axis;
- b. said connecting element joins said first wire and said second wire;
- c. said connecting element comprises a first stop element;
- d. said second wire comprises a second stop element;
- and
- e. said first stop element is configured to reversibly engage said second stop element such that said second wire is only able to freely rotate relative to said connecting element over a distance of between 10 and 360 degrees.
4 more elements
A device for deflecting emboli, the device comprising:
- a lateral structure to support an emboli filter, a length of said lateral structure being between 80 mm and 90 mm and a width of said lateral structure being from 20 mm to 35 mm, having the filter attached to and extending the length of said lateral structure;
- a lower member extending downward from said lateral structure in a direction of an ascending aorta, wherein upon installation of said device, said lower member exerts lift on a middle area of said lateral structure;
- and
- an upper member extending upwards from said lateral structure, wherein a support portion of said upper member being proximate to said lateral structure is angled towards the ascending aorta, and an anchor portion of said upper member being distal to said lateral structure is angled towards the descending aorta,
- wherein upon said installation, said upper member limits said lift;
- wherein said device comprises three or more radiopaque elements;
- and
- wherein said three or more radiopaque elements are positioned asymmetrically.
