Abstract
A guidewire loading system includes a catheter having a catheter body having an internal lumen and a snare. The snare is positioned at least partially within the internal lumen of the catheter body. The snare includes a snare body and a first capture flare extending from a first end of the snare body and configured to receive the guidewire. The catheter body compresses the first capture flare to form a friction grip around the guidewire when the snare, including the first capture flare, and guidewire are pulled at least partially through the internal lumen of the catheter body.
Claims13
A guidewire loading system, comprising:
- a catheter comprising an elongate catheter body defining an internal lumen, wherein the catheter is sized to traverse through a subject's vasculature;
- and
- a snare at least partially positioned within the internal lumen of the catheter body, the snare comprising:
- a snare body;
- and
- a first capture flare extending from a first end of the snare body and a second capture flare extending from a second end of the snare body, wherein:
- the first capture flare and the second capture flare have frustoconical outer surfaces in an uncompressed configuration;
- the first capture flare is configured to receive a guidewire, wherein the catheter body compresses the first capture flare to form a friction grip around the guidewire when the snare, including the first capture flare, and the guidewire are pulled at least partially through the internal lumen of the catheter body;
- and
- the second capture flare is configured to receive the guidewire, wherein the catheter body compresses the second capture flare to form a friction grip around the guidewire when the snare, including the second capture flare, and the guidewire are pulled at least partially through the internal lumen of the catheter body.
A guidewire snare, comprising:
- a snare body;
- a first capture flare extending from a first end of the snare body and configured to receive a guidewire;
- and
- a second capture flare extending from a second end of the snare body and configured to receive the guidewire, wherein:
- the first capture flare and the second capture flare have frustoconical outer surfaces in an uncompressed configuration;
- the first capture flare is configured to form a friction fit around the guidewire when the first capture flare is pulled at least partially through an internal lumen of a catheter body;
- and
- the second capture flare is configured to form a friction fit around the guidewire when the second capture flare is pulled at least partially through the internal lumen of the catheter body.
