Abstract
Abstract A laser delivery system for ophthalmic surgery and the like includes a handpiece terminating distally in a probe, a laser connector, and an optical fiber for transmitting laser light from a laser source to an eye to be treated. The optical fiber extends substantially through the handpiece probe. The probe also includes a fluid path from the distal end thereof to the interior of the handpiece body. The probe has a soft tip to reduce the possibility of injury to the interior of the eye by contact with the metal portion of the probe.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A laser delivery system for ophthalmic surgery and the like comprising: a handpiece having a handpiece body and a hollow probe of a size suitable for insertion into a human eye, said hollow probe extending distally from the handpiece body and including a metal tube forming the proximal portion of the probe; a laser connector for connection to a laser source; an optical fiber terminating at one end in the laser connector and terminating at another end in the handpiece for transmitting laser light from a laser course to an eye to be treated; and a soft tip forming the distal end of said probe.
Claim 2
Dependent Claim
105 words
A laser delivery system for ophthalmic surgery and the like comprising: a handpiece having a handpiece body and a hollow probe of a size suitable for insertion into a human eye, said hollow probe extending distally from the handpiece body and including a metal tube forming the proximal portion of the probe; a laser connector for connection to a laser source; an optical fiber terminating at one end in the laser connector and terminating at another end in the handpiece for transmitting laser light from a laser course to an eye to be treated; and a soft tip forming the distal end of said probe.
Claim 3
Dependent Claim
37 words
The laser delivery system of claim 1 wherein said soft tip comprises a tube made of a soft pliable material which is received at least partly in said metal tube and extends distally beyond said metal tube.
Claim 4
Dependent Claim
18 words
The laser delivery system of claim 2 wherein said soft pliable tube is frictionally held in said probe.
Claim 5
Dependent Claim
38 words
A handpiece for an ophthalmic laser delivery system including a handpiece body and a probe of a size suitable for insertion in a human eye extending from an end of said handpiece, said probe having a soft tip.
Claim 6
Dependent Claim
38 words
A handpiece for an ophthalmic laser delivery system including a handpiece body and a probe of a size suitable for insertion in a human eye extending from an end of said handpiece, said probe having a soft tip.
Claim 7
Dependent Claim
57 words
The handpiece of claim 4 wherein the proximal end of said probe is composed of a relatively hard material and said soft tip comprises a tube made of a soft pliable material which is received at least partly in said hard proximal portion of said probe and extends distally beyond said hard proximal portion of said probe.
Claim 8
Dependent Claim
21 words
The handpiece of claim 5 wherein said soft pliable tube is frictionally held in said hard proximal portion of said probe.
Claim 9
Dependent Claim
10 words
The handpiece of claim 4 wherein the probe is curved.
Claim 10
Dependent Claim
15 words
The handpiece of claim 7 wherein the probe is curved proximally of the soft tip.
