Claims
- 1. A method of preparing an anatomical vessel contained within a tissue bundle for ligation, comprising the steps of:
positioning a cannula adjacent to said tissue bundle, wherein said positioning is non-penetrating, said cannula including a first extendable member, a second extendable member, a Doppler wand, and a distal end; transmitting ultrasound signals toward said vessel through said tissue bundle with said Doppler wand; receiving ultrasound signals reflected by said vessel through said tissue bundle with said Doppler wand; invaginating said tissue bundle with said first extendable member on a first side of said tissue bundle; invaginating said tissue bundle with said second extendable member on a second side of said bundle opposite said first side; and interpenetrating a length of ligation material between said first and second extendable members on a side of said vessel opposite said cannula distal end.
- 2. The method as set forth to claim 1, wherein said first extendable member includes a detachable element to which said ligation material is attached, and further comprising grabbing said detachable element with portions of said second extendable member.
- 3. The method as set forth to claim 1, further comprising the steps of:
retracting said second extendable member in a proximal direction; and releasing said detachable element from said first extendable member.
- 4. The method as set forth to claim 1, wherein said first extendable member includes a tissue penetrating element to which said ligation material is attached, and further comprising piercing said tissue penetrating element into said tissue bundle.
- 5. The method as set forth to claim 4, wherein said tissue penetrating element includes a detachable element to which said ligation material is attached, and further comprising grabbing said detachable element with portions of said second extendable member.
- 6. The method as set forth to claim 4, further comprising the steps of:
retracting said second extendable member in a proximal direction; and releasing said detachable element from said first extendable member.
- 7. A ligation device for invaginating tissue adjacent to a vessel contained within the tissue bundle comprising:
means for noninvasively positioning a cannula about said tissue bundle, said cannula including a Doppler wand and a distal end; means for transmitting ultrasound signals toward said vessel through said tissue bundle with said Doppler wand; means for receiving ultrasound signals reflected by said vessel through said tissue bundle with said Doppler wand; first means for invaginating said tissue bundle on a first side of said tissue bundle; second means for invaginating said tissue bundle on a second side of said bundle opposite said first side; and means for interpenetrating a length of ligation material between said first and second invaginating means on a side of said vessel opposite said cannula distal end.
- 8. The device as set forth to claim 7, wherein said first invaginating means comprises a first extendable member having a detachable element to which said ligation material is attached, and further comprising means for grabbing said detachable element with portions of said second invaginating means.
- 9. The device as set forth to claim 8, wherein said second invaginating means includes a second extendable member, and further comprising:
means for retracting said second extendable member in a proximal direction; and means for releasing said detachable element from said first extendable member.
- 10. The device as set forth to claim 7, wherein said first extendable member includes a tissue penetrating element to which said ligation material is attached, and further comprising means for piercing said tissue penetrating element into said tissue bundle.
- 11. The device as set forth to claim 10, wherein said tissue penetrating element includes a detachable element to which said ligation material is attached, and further comprising means for grabbing said detachable element with portions of said second extendable member.
- 12. The device as set forth to claim 10, further comprising:
means for retracting said second invaginating means in a proximal direction; and means for releasing said detachable element from said first extendable member.
