Snare
An intravascular snare device for use in capturing debris found in blood vessels. The snare device is fabricated from a tube and includes longitudinally and circumferentially extending members. The snare device specifically embodies structure that provides enhanced radial opening and angular resistance to collapse.
1. A method involving a snare device for use within vasculature comprising,
configuring the snare device to capture material found within vasculature by providing the snare device with a body portion manufactured from a tube, the body portion attached to an elongate member;
placing the snare device within vasculature so that a portion of the elongate member extends exterior vasculature; and
capturing material in the body portion of the snare device.
2. The method of claim 1 , wherein said configuring step further includes positioning the snare device within vasculature of a patient.
3. The method of claim 2 , further comprising the step of providing a guide catheter and allowing a moment of bleed back from the vasculature and through the guide catheter to flush any loose undesirable material.
4. The method of claim 3 , wherein the guide catheter includes a detachable adaptor and further comprising the step of attaching a supplemental adapter to the guide catheter.
5. The method of claim 4 , further comprising the step of flushing the guide catheter with saline.
6. The method of claim 1 , wherein said configuring step further includes positioning the snare device within intracranial vasculature of a patient.
7. The method of claim 1 , wherein said configuring step further includes positioning the snare device distal of a blood clot within intracranial vasculature of a patient.
8. The method of claim 1 , further comprising configuring the snare device in an expanded condition.
9. The method of claim 1 , further comprising enclosing material within the body portion.
10. The method of claim 1 , further comprising:
configuring the snare device to be slideably received within a guide catheter that includes a detachable adaptor;
withdrawing the snare device to a position adjacent an opening to the guide catheter;
aspirating the guide catheter while withdrawing the snare device into the guide catheter;
maintaining aspirations until the snare device is positioned within the adaptor; and
detaching the adaptor, with the snare device contained therein, from the guide catheter.
