1. A surgical clip comprising a single, continuous, resilient member formed along a clip axis without machining operations which remove material or joining operations which add material and including:
- a coil spring positioned on the axis and at one end of said clip;
a first arm having(i) a first flex section extending from said spring away from said clip axis to a point farthest from said clip axis then toward said clip axis so that said first flex section is disposed lengthwise along said clip axis, resiliently deformable from its position with respect to said clip axis, and forming a first forceps-gripping elbow at the point in said first arm farthest from said clip axis,(ii) a first clamping jaw positioned at one free end of said resilient member, and(iii) a guided element which makes a simple turn of less than 180 degrees between said first forceps-gripping elbow and said first clamping jaw; and
a second arm having(i) a second flex section extending from said spring away from said clip axis to a point farthest from said clip axis then toward said clip axis so that said first flex section is disposed lengthwise along said clip axis on the opposite side of said clip axis from said first flex section, resiliently deformable from its position with respect to said clip axis, and forming a second forceps-gripping elbow at the point in said second arm farthest from said clip axis,(ii) a second clamping jaw positioned at the second free end of said resilient member, and(iii) a bent guide section positioned between said second forceps-gripping elbow and said second clamping jaw confining movement of said guided element at three points, with two of said points positioned in an essentially common plane on one side of said guided element and the third point positioned on the opposite side of said guided element, said movement of said guided element within said bent guide section confined to two degrees of freedom;

Abstract
A surgical clip formed from a continuous, resilient member and having a coil spring and two arms supporting clamping jaws. The coil spring forces the clamping jaws together. One arm has a guide section, through which the guided element of the second arm extends, to guide and restrict movement of the second arm, thereby correctly engaging the clamping jaws.

36. A surgical clip comprising a single, continuous, resilient member formed along a clip axis without machining operations which remove material or joining operations which add material and including:
-
a coil spring positioned on the axis and at one end of said clip; a first arm having (i) a first flex section extending from said spring away from said clip axis to a point farthest from said clip axis then toward said clip axis so that said first flex section is disposed lengthwise along said clip axis, resiliently deformable from its position with respect to said clip axis, and forming a first forceps-gripping elbow at the point in said first arm farthest from said clip axis, (ii) a first clamping jaw positioned at one free end of said resilient member, and (iii) a guided element which makes a simple turn of less than 180 degrees between said first forceps-gripping elbow and said first clamping jaw; and a second arm having (i) a second flex section extending from said spring away from said clip axis to a point farthest from said clip axis then toward said clip axis so that said first flex section is disposed lengthwise along said clip axis on the opposite side of said clip axis from said first flex section, resiliently deformable from its position with respect to said clip axis, and forming a second forceps-gripping elbow at the point in said second arm farthest from said clip axis, (ii) a second clamping jaw positioned at the second free end of said resilient member, and (iii) a bent guide section positioned between said second forceps-gripping elbow and said second clamping jaw confining movement of said guided element at three points, with two of said points positioned in an essentially common plane on one side of said guided element and the third point positioned on the opposite side of said guided element, wherein said bent guide section is open and makes a substantially perpendicular, L-shaped pivot between the two movement-confining points positioned in an essentially common plane on one side of said guided element; whereby said coil spring is located between said first and second flex sections urging said first and second clamping jaws against each other.
