Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
85 words
A surgical drain comprising a series of rods lying on two horizontal planes, the rods of one plane staggered in relation to the rods on the other plane, the rods on the same plane in spaced relation to each other and the rods on the plane connected to adjacent rods on the other plane by a web the drain adapted to be torn along a web on a line substantially parallel to a rod and adjacent rods are in acute angular relation to each other.
Claim 2
Dependent Claim
85 words
A surgical drain comprising a series of rods lying on two horizontal planes, the rods of one plane staggered in relation to the rods on the other plane, the rods on the same plane in spaced relation to each other and the rods on the plane connected to adjacent rods on the other plane by a web the drain adapted to be torn along a web on a line substantially parallel to a rod and adjacent rods are in acute angular relation to each other.
Claim 3
Dependent Claim
80 words
A surgical drain formed of elastomeric material having a series of spaced channels substantially wedge shaped in cross section defined by walls, each of the walls comprising a first rod portion and a second rod portion connected by a web portion wherein the first rod portion lies on the first plane and the second rod portion lies on a second plane spaced from the first plane and the first rod portion is in staggered relation to the second rod portion.
Claim 4
Dependent Claim
80 words
A surgical drain formed of elastomeric material having a series of spaced channels substantially wedge shaped in cross section defined by walls, each of the walls comprising a first rod portion and a second rod portion connected by a web portion wherein the first rod portion lies on the first plane and the second rod portion lies on a second plane spaced from the first plane and the first rod portion is in staggered relation to the second rod portion.
Claim 5
Dependent Claim
45 words
A drain as set forth in claim 2 wherein the distance between the surface of the first rod portion of the one wall and the surface of the rod portion of the other wall is less than the distance between the webs of the walls.
