Abstract
Intraluminal devices and methods of fabricating intraluminal devices may be provided. In one implementation, an intraluminal device may be formed of a plurality of wires and may include a distal coil, a proximal coil, and an expandable mesh segment positioned between the distal and proximal coils. The proximal coil may include more wires of the plurality of wires than the distal coil and the expandable mesh segment. Due to the smaller number of wires forming the distal coil, the intraluminal device may be configured to have a soft and atraumatic distal tip and a more rigid proximal cable.
Claims15
An intraluminal device including an elongated body formed of a plurality of wires, the intraluminal device comprising:
- a first region wherein the plurality of wires are twisted to form a first cable;
- a second region, distal to the first region, in which the plurality of wires are woven to form an expandable mesh segment which is configured to capture a blood clot;
- and
- a third region distal to the second region and forming a distal tip of the elongated body, wherein the plurality of wires in the third region are twisted to form a second cable,
- wherein each of the wires extends continuously from the first region, through the second region to the third region providing a smooth device profile;
- wherein the second region includes one or more wire crossings where one or more extraneous wires of the plurality of wires, adjacent to a different wire of the plurality of wires, is embedded by following a weave pattern of the different wire;
- wherein the one or more wire crossings includes a crossing of a first grouping of wires and a second grouping of wires;
- wherein the first grouping of wires include at least three wires, including the one or more extraneous wires;
- wherein wires of the first grouping of wires excluding the one or more extraneous wires are twisted together to provide at least one twist at least one location away from the crossing.
A method of manufacturing an intraluminal device including an elongated body formed of a plurality of wires, the method comprising:
- twisting a plurality of wires upon a first segment of a mandrel so as to form a first cable of the elongated body;
- weaving each of the wires upon a second segment of the mandrel distal to the first segment,
- the weaving including forming one or more wire crossings with the plurality of wires, so as to form an expandable mesh segment of the elongated body which is configured to capture a blood clot,
- wherein the weaving comprises embedding one or more extraneous wires of the plurality of wires, adjacent to a different wire of the plurality of wires, by following a weave pattern of the different wire;
- wherein the forming one or more wire crossings comprises crossing a first grouping of wires and a second grouping of wires;
- wherein the first grouping of wires includes at least three wires, including the one or more extraneous wires;
- wherein the forming comprises twisting together wires of the first grouping of wires excluding the one or more extraneous wires to provide at least one twist at least one location away from the crossing;
- and
- twisting each of the plurality of wires upon a third segment of the mandrel so as to form a second cable of the elongated body, each wire of the plurality of wires extending continuously from the first cable, through the expandable mesh segment, to the second cable, providing a smooth device profile;
- wherein the second segment of the mandrel is positioned between the first segment of the mandrel and the third segment of the mandrel.
