ABSTRACT:
An improved distal end for a ligating band dispenser having a transverse groove or ridge profile that promotes rolling of the bands. In one embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is substantially the same as the pitch of the transverse grooves or ridges. In another embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is less than the pitch of the transverse grooves or ridges. Having the width of the bands when stretched on the support surface be substantially the same as or less than the pitch of the transverse grooves or ridges allows the bands to fit within the grooves, which helps insure that the bands are sufficiently held back by the ridge crests to induce a rolling action. In addition, the transverse grooves or ridges may also be dimensioned such that the height of the ridge crests is sufficiently high to insure that the bands are sufficiently held back by the ridge crests to induce a rolling action.
