Abstract
Abstract A multi-shaft apparatus for incising a substrate of soft resilient material such as a body tissue. The incising apparatus includes two or more incision shafts each having a distal edge. The shafts are not affixed to each other and are allowed to slide against each other to drive the distal edges alternately against the substrate to incise the substrate. In the case of incising a body tissue, such alternate motion would result in less pain to the patient than a puncture resulting from a sharp jab by a sharp shaft of similar size to the shafts.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
83 words
A method for incising a soft resilient substrate, comprising: driving at least two or more parallel incision shafts so that the at least one shaft moves periodically relative to another of the incision shafts in translational position or rotational position, the incision shafts each having a distal end; urging the shafts in a direction parallel to the shafts toward the soft resilient substrate such that the distal ends of the shafts are driven into the soft resilient substrate to result in a hole.
Claim 2
Independent Claim
83 words
A method for incising a soft resilient substrate, comprising: driving at least two or more parallel incision shafts so that the at least one shaft moves periodically relative to another of the incision shafts in translational position or rotational position, the incision shafts each having a distal end; urging the shafts in a direction parallel to the shafts toward the soft resilient substrate such that the distal ends of the shafts are driven into the soft resilient substrate to result in a hole.
Claim 3
Dependent Claim
50 words
A method according to claim 1 wherein the shafts are associated with one another in an apparatus and the method comprises steadying the apparatus against the substrate with one shaft and driving at least one of the other shafts to move relative to the steadying shaft to incise the substrate.
Claim 4
Dependent Claim
24 words
A method according to claim 1 comprising sliding the shafts against each other and associating the shafts to include a channel for liquid flow.
Claim 5
Dependent Claim
16 words
A method according to claim 1 comprising moving each of the shafts intermittently in noncontinuous motion.
Claim 6
Dependent Claim
40 words
A method according to claim 1 wherein the edges of the shafts are beveled each to form a sharp edge with a bevel surface and comprising arranging the neighboring bevel surfaces of two shafts to face away from each other.
Claim 7
Dependent Claim
40 words
A method according to claim 1 wherein the edges are beveled to each form a sharp edge with a bevel surface and comprising aligning the shafts such that the the neighboring bevel surfaces of two shafts face the same direction.
Claim 8
Dependent Claim
25 words
A method according to claim 1 comprising moving at least one of the shafts in translational position relative to the other in reciprocating longitudinal action.
Claim 9
Dependent Claim
