Abstract:
1. A surgical clip for ligating a tubular vessel in vivo, the clip consisting essentially of: a first clip portion comprising: a second clip portion coupled to the first clip portion, comprising; a hinge portion coupling the first and second clip portions positioned at a first end of the first and second clip portions, comprising: a lock for locking the clip portions together when in use such that the tubular vessel placed between the first and second clip portions is ligated, comprising: wherein the first lock portion and the second lock portion are positioned to cooperate to lock the clip portions together during use; wherein at least one of the clamping surfaces comprises surface undulation and at least a portion of the surface undulation contacts the tubular vessel during use; wherein the clamping surfaces and hinge portion are positioned such that the clamping surfaces are substantially parallel to one another when the tubular vessel is ligated during use; means providing a stand-off gap between the clamping surfaces of at least 0.1 mm across the length of clamping surfaces in the absence of the tubular vessel when the clip is in the closed position; wherein a first maximum dimension of the clip in a first direction is between about 0.25 and about 1.0 times a second maximum dimension of the clip in a second direction and wherein the first and second directions are orthogonal to each other and the first and second directions are parallel with the clamping surfaces when the clip is in the closed condition; wherein in use the tubular vessel is accommodated when positioned between the first clamping surface and the second clamping surface; wherein in use the clip has a substantially smooth substantially spherical or substantially ovoid external 3-dimensional shape that is substantially free of:
