Abstract

Abstract A method of cutting a suture at least partly disposed in tissue and bearing a knot formed in the suture, wherein the suture is introduced into the slot of a suture cutter having a slotted member of a predetermined depth and a cutting blade relatively moveable with respect to the slotted member, the cutter is moved along the suture until the member contacts the knot, and the cutting blade is relatively moved across the slot to shearingly contact the suture such that a stub substantially equal in length to the depth of the slotted member remains on the suture adjacent the knot.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 169 words
A method of cutting a suture at least partly disposed in tissue and bearing a knot formed in the suture, comprising the steps of: introducing the suture into the slot of an elongated suture cutter having a slotted member of a predetermined depth and a cutting blade relatively moveable with respect to the slotted member and substantially perpendicular to the elongation of the suture cutter, said introduction of the suture into the slot being performed by moving the suture cutter longitudinally parallel to its elongation so that the suture is thereby introduced into the slot which extends along the direction of elongation of the suture cutter; moving the suture cutter along the suture within the slot until the member contacts the knot; and moving the cutting blade across the slot and substantially perpendicular to the elongation of the suture cutter so as to cut the suture and automatically leave on the suture and adjacent the knot a stub substantially equal in length to the depth of the slotted member.
Claim 2
Independent Claim 169 words
A method of cutting a suture at least partly disposed in tissue and bearing a knot formed in the suture, comprising the steps of: introducing the suture into the slot of an elongated suture cutter having a slotted member of a predetermined depth and a cutting blade relatively moveable with respect to the slotted member and substantially perpendicular to the elongation of the suture cutter, said introduction of the suture into the slot being performed by moving the suture cutter longitudinally parallel to its elongation so that the suture is thereby introduced into the slot which extends along the direction of elongation of the suture cutter; moving the suture cutter along the suture within the slot until the member contacts the knot; and moving the cutting blade across the slot and substantially perpendicular to the elongation of the suture cutter so as to cut the suture and automatically leave on the suture and adjacent the knot a stub substantially equal in length to the depth of the slotted member.
Claim 3
Dependent Claim 112 words
A method of cutting a suture in accordance with claim 1 wherein relative movement of the cutting blade and slotted member causes the blade to bear against the member and close the slot in advance of suture shearing movement of the blade across the slot, said method further comprising: relatively moving the cutting blade into bearing relation against the member so as to close the slot after said introduction of the suture into the slot and prior to said moving of the suture cutter along the suture into contact with the knot, whereby the suture is prevented from slipping out of the slot as the suture cutter is moved along the suture.
