Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
124 words
A medical device for transmitting light energy to a patient's tissue, said device comprising: an elongated light transmitting conduit comprising an optical fiber, said conduit having a proximal end adapted for connection to a light energy source and a distal end formed by a portion of said optical fiber; an enlarged orb portion integrally formed on said distal end by material forming a portion of said optical fiber; an elongated cylindrical portion extending distally from said enlarged portion from material forming a portion of said optical fiber, said cylindrical portion being smaller in diameter than said orb portion; and aperture means on said elongated portion for allowing at least a portion of light to pass therethrough when the light is transmitted through said conduit.
Claim 2
Dependent Claim
124 words

Claim 3
Dependent Claim
19 words
The device of claim 1 wherein said aperture means is characterized by a polished tip of said elongated portion.
Claim 4
Dependent Claim
18 words
The device of claim 1 wherein an outer surface of said enlarged portion is at least partially frosted.
Claim 5
Dependent Claim
21 words
The device of claim 1 wherein outer surfaces of said enlarged portion and said elongated portion are at least partially frosted.
Claim 6
Dependent Claim
42 words
The device of claim 1 wherein said enlarged portion is sized for positioning adjacent a patient's tubal ostia such that light energy transmitted through said conduit may be used to close a fallopian tube of the patient and thereby sterilize the patient.
Claim 7
Dependent Claim
121 words
A medical device for transmitting light energy to tissue adjacent a patient's tubal ostia in order to close the patient's fallopian tubes and sterilize the patient, said medical device comprising: an elongated light transmitting conduct comprising an optical fiber, said conduct having a proximal end adapted for connection to a light energy source and a distal end formed from a portion of said optical fiber; an orb portion integrally formed on said distal end from material forming a portion of said optical fiber; and an elongated cylindrical portion integrally formed on said distal end from material forming a portion of said optical fiber and extending distally form said orb portion, said cylindrical portion having a diameter smaller than said orb portion.
Claim 8
Dependent Claim
121 words
A medical device for transmitting light energy to tissue adjacent a patient's tubal ostia in order to close the patient's fallopian tubes and sterilize the patient, said medical device comprising: an elongated light transmitting conduct comprising an optical fiber, said conduct having a proximal end adapted for connection to a light energy source and a distal end formed from a portion of said optical fiber; an orb portion integrally formed on said distal end from material forming a portion of said optical fiber; and an elongated cylindrical portion integrally formed on said distal end from material forming a portion of said optical fiber and extending distally form said orb portion, said cylindrical portion having a diameter smaller than said orb portion.
Claim 9
Dependent Claim
64 words
The device of claim 6 wherein said optical fiber comprises: a core; a cladding disposed around said core; and a jacket disposed around said cladding; wherein: a bare portion of said core extends from said cladding and jacket; and said orb portion and said elongated portion are integrally formed with said bare core portion from material forming a portion of said bare core portion.
Claim 10
Dependent Claim
