Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
99 words
The method of positioning instruments within the eye comprising the steps of: Positioning a supporting means having a passage therethrough adjacent a selected area of the outer wall of the eye, Moving a cutting means into the wall of the eye within said selected area to pierce said wall and form an opening therein, Moving said supporting means with said cutting means into said opening so that a portion of said supporting means extends through the wall of the eye to provide access for an instrument into the interior of the eye through the passageway of said supporting means.
Claim 2
Independent Claim
99 words
The method of positioning instruments within the eye comprising the steps of: Positioning a supporting means having a passage therethrough adjacent a selected area of the outer wall of the eye, Moving a cutting means into the wall of the eye within said selected area to pierce said wall and form an opening therein, Moving said supporting means with said cutting means into said opening so that a portion of said supporting means extends through the wall of the eye to provide access for an instrument into the interior of the eye through the passageway of said supporting means.
Claim 3
Dependent Claim
72 words
The method of claim 1 further comprising the step assembling the cutting means to the supporting means to move therewith prior to moving said cutting means into the wall of the eye so that said cutting means and supporting means can be moved together, and moving said cutting means and said supporting means so that said cutting means first forms the opening and the supporting means is thereafter moved through said opening.
Claim 4
Dependent Claim
21 words
The method of claim 2 wherein said assembling step comprises placing said cutting means through the passageway of said supporting means.
Claim 5
Dependent Claim
31 words
The method of claim 3 further comprising the steps of withdrawing said cutting means through said passageway of said supporting means and inserting an instrument into the eye through said passageway.
Claim 6
Dependent Claim
20 words
The method of claim 1 further comprising the step of mounting said supporting means to the wall of the eye.
Claim 7
Dependent Claim
92 words
The method according to claim 3 further comprising the steps of releasably locking said cutting means to said supporting means with said cutting means positioned within said passageway of said cutting means and having a cutting surface extending beyond the front of said supporting means, and moving said assembled cutting means and supporting means to first force the cutting surface of said cutting means into the wall of the eye to penetrate the wall to form the opening for receiving said supporting means and then move the supporting means into the opening.
Claim 8
Dependent Claim
38 words
The method according to claim 6 further comprising the steps of: unlocking said cutting means from said supporting means, removing said cutting means from said passageway, and inserting instrumentation through said passageway into the interior of the eye.
Claim 9
Dependent Claim
26 words
The method accordIng to claim 1 further comprising the step of retaining said supporting means in fixed axial position relative to the wall of said eye.
Claim 10
Dependent Claim
43 words
The method according to claim 1 further comprising the step of forming a seal between the opening formed by said cutting means and the supporting means extending therethrough to prevent the escape of the vitreous material contained within the eye through said opening.
Claim 11
Dependent Claim
32 words
The method according to claim 9 wherein the step of forming said seal includes applying at least one suture through the wall of the eye in surrounding relation to said supporting means.
Claim 12
Dependent Claim
41 words
The method according to claim 1 further comprising the steps of: a. inserting an instrument through said passageway, and b. sealing said instrument within said passageway to prevent the escape of the vitreous material contained within the eye through said passageway.
Claim 13
Dependent Claim
51 words
The method according to claim 11 further comprising the steps of: a. removing said instrument from within said passageway, b. inserting in said passageway means for removing said supporting means, and c. moving said removing means outwardly from the eye for disengaging said supporting means from the wall of the eye.
Claim 14
Independent Claim
130 words
The method of positioning instrumentation within the eye utilizing cutting means having a cutting surface, and supporting means having a passageway extending therethrough, comprising the steps of: A. releasably assembling said cutting means with said supporting means such that said cutting means extends within said passageway and said cutting surface extends beyond the front end of said supporting means, B. forcing said assembled supporting means and cutting means through the wall of the eye with said cutting surface first penetrating the wall of the eye to form an opening therein, and continuing said force until said supporting means extends through the wall of the eye, C. disassembling said cutting means from said supporting means, D. removing said cutting means from said passageway, and E. inserting through said passageway the instrumentation.
Claim 15
Independent Claim
130 words
The method of positioning instrumentation within the eye utilizing cutting means having a cutting surface, and supporting means having a passageway extending therethrough, comprising the steps of: A. releasably assembling said cutting means with said supporting means such that said cutting means extends within said passageway and said cutting surface extends beyond the front end of said supporting means, B. forcing said assembled supporting means and cutting means through the wall of the eye with said cutting surface first penetrating the wall of the eye to form an opening therein, and continuing said force until said supporting means extends through the wall of the eye, C. disassembling said cutting means from said supporting means, D. removing said cutting means from said passageway, and E. inserting through said passageway the instrumentation.
Claim 16
Dependent Claim
32 words
The method according to claim 13, and including the step of sealing said instrumentation within said passageway to prevent the escape of the vitreous material contained within the eye through said passageway.
Claim 17
Dependent Claim
42 words
The method according to claim 13, and including the steps of: a. removing said instrumentation from within said passageway, b. inserting in said passageway removing means in sealing engagement therewith, and c. disengaging said supporting means from the wall of the eye.
Claim 18
Dependent Claim
38 words
The method according to claim 13, and including the step of forming a seal between the opening and the supporting means extending therethrough to prevent the escape of the vitreous material contained within the eye through said opening.
