Abstract
Ligation bands are provided having improved compression and anti-slip properties. For example, a ligation band can be provide with a substantially ring-shaped elastic body that has a first tissue-contacting surface, a second tissue-contacting surface opposite the first tissue-contacting surface, and an aperture that extends therethrough. At least one of the tissue-contacting surfaces can have a plurality of protrusions that define an interlinking web-pattern with a plurality of recesses.
Claims20
A ligation band, comprising:
- a substantially ring-shaped elastic body having a first tissue-contacting surface, a second tissue-contacting surface opposite the first tissue-contacting surface, and an aperture extending therethrough, wherein at least one of the tissue-contacting surfaces has a plurality of protrusions formed thereon that define an interlinking web-pattern with a plurality of recesses therebetween.
A ligation band, comprising:
- a substantially ring-shaped elastic body having first and second tissue-contacting surfaces thereon and a central opening extending therethrough, each of the first and second tissue-contacting surfaces having four delta-shaped protrusions projecting therefrom and spaced around the central opening, each delta-shaped protrusion defining a substantially delta-shaped recess therein and each delta-shaped protrusion being configured to grip tissue.
A method of ligating tissue, comprising:
- drawing tissue into an inner lumen of an elongate shaft;
- advancing a ligation band distally along the elongate shaft and distally off of a distal end of the elongate shaft to position the ligation band around the tissue drawn into the inner lumen of the elongate shaft, the ligation band having a plurality of protrusions formed on first and second opposed tissue-contacting surfaces thereof that grip the enclosed tissue to resist slipping, the plurality of protrusions defining an interlinking web-pattern having a plurality of recesses therebetween that receive the tissue therein.
