Title:
ドップラー効果によって案内される縫合結紮デバイスおよび方法
Document Type and Number:
Japanese Patent JP4094947
Kind Code:
B2
Abstract:
A ligation device includes a cannula having first and second extendable members and a Doppler wand. The Doppler wand permits an anatomical vessel, such as a blood vessel, to be located in close proximity to the distal end of the cannula. The extendable members are extendable on two opposite sides of the vessel. A length of ligation material, such as suture material, extends through the first extendable member, and is attached to a detachable element mounted to the distalmost end of the extendable member. The second extendable member includes a snare. The first extendable member includes curved portions which, when the member is extended distally, extend the detachable element into position for the snare so that the snare can grab the loop. Once ensnared, the detachable element is released from the first extendable member, which pulls the ligation material around the vessel. The ligation device does not require prior visualization or dissection of the area around the vessel.
