Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
A macular indenter for positioning over a macular area of an eye, the indenter comprising a generally J-shaped tubular strip of biocompatible material having a pair of opposed ends and a diameter, the strip having a raised portion at one end of the J-shaped strip for indenting the macular area of the eye, the raised portion closes the one end of the tubular strip and has a diameter which is not greater than the diameter of the J-shaped strip.
Claim 2
Dependent Claim
79 words
A macular indenter for positioning over a macular area of an eye, the indenter comprising a generally J-shaped tubular strip of biocompatible material having a pair of opposed ends and a diameter, the strip having a raised portion at one end of the J-shaped strip for indenting the macular area of the eye, the raised portion closes the one end of the tubular strip and has a diameter which is not greater than the diameter of the J-shaped strip.
Claim 3
Dependent Claim
21 words
The macular indentor of claim 1 wherein the raised portion has a domed shape which applies pressure on the macular area.
Claim 4
Dependent Claim
21 words
The macular indentor of claim 1 wherein the raised portion has a flat surface which applies pressure on the macular area.
Claim 5
Dependent Claim
21 words
The macular indentor of claim 1 wherein the raised portion has a serrated surface which applies pressure on the macular area.
Claim 6
Dependent Claim
25 words
The macular indentor of claim 1 wherein the strip is hollow and the raised portion is inflatable to selectively apply pressure to the macular area.
Claim 7
Dependent Claim
24 words
The macular indentor of claim 1 wherein the eye includes a sclera and the end opposite the raised portion is sutured to the sclera.
Claim 8
Independent Claim
108 words
A method of treating a disorder of an eye, the eye having a macular area and a sclera, the method comprising the steps of positioning over the macular area a macular indentor comprising a generally J-shaped tubular strip of biocompatible material having a pair of opposed ends and a diameter, the strip having a raised portion at one end of the J-shaped strip for indenting the macular area of the eye, the raised portion closes the one end of the tubular strip and has a diameter which is not greater than the diameter of the J-shaped strip, and suturing at least one of the ends to the sclera.
Claim 9
Independent Claim
108 words
A method of treating a disorder of an eye, the eye having a macular area and a sclera, the method comprising the steps of positioning over the macular area a macular indentor comprising a generally J-shaped tubular strip of biocompatible material having a pair of opposed ends and a diameter, the strip having a raised portion at one end of the J-shaped strip for indenting the macular area of the eye, the raised portion closes the one end of the tubular strip and has a diameter which is not greater than the diameter of the J-shaped strip, and suturing at least one of the ends to the sclera.
Claim 10
Dependent Claim
36 words
The method of claim 7 wherein the strip further comprises a raised portion and the method further comprises the step of positioning the raised portion over the macular area to apply pressure to the macular area.
Claim 11
Dependent Claim
33 words
The method of claim 8 wherein the raised portion is inflatable and the method further comprises the step of inflating the raised portion once the raised portion is positioned over the macular area.
