Abstract
Abstract An optical fiber device for forming channels within a wall of a patient's heart, and particularly the epicardium, which has an elongated optical fiber, a probe tip secured to the distal end of the optical fiber and an outer support tube secured to the proximal portion of the probe tip and a distal portion of the optical fiber proximal to the probe tip. A handle is described for a flexible optical fiber device which greatly facilitates delivery of the distal end of the optical fiber device to a desired location on the exterior of a patient's heart.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
An intraoperative device for forming a channel within a wall of a patient's heart comprising: a) an elongated member having a distal extremity with a channel forming means thereon and having a longitudinal axis extending therethrough; and b) a handle which is secured to the distal extremity of the elongated member at a substantial angle with respect to a longitudinal axis extending through the distal extremity of the elongated member to facilitate advancement of the channel forming means against the wall of the patient's heart and which has an intermediate shapable section.
Claim 2
Dependent Claim
92 words
An intraoperative device for forming a channel within a wall of a patient's heart comprising: a) an elongated member having a distal extremity with a channel forming means thereon and having a longitudinal axis extending therethrough; and b) a handle which is secured to the distal extremity of the elongated member at a substantial angle with respect to a longitudinal axis extending through the distal extremity of the elongated member to facilitate advancement of the channel forming means against the wall of the patient's heart and which has an intermediate shapable section.
Claim 3
Dependent Claim
28 words
The intraoperative device of claim 1 wherein the handle has a proximal section and a distal section with the shapable intermediate section between the proximal and distal sections.
Claim 4
Dependent Claim
24 words
The intraoperative device of claim 2 wherein the proximal section of the handle is provided with a gripping means to facilitate manual movement thereof.
Claim 5
Dependent Claim
25 words
The intraoperative device of claim 2 wherein the handle is provided with an aperture in the distal end thereof to receive the channel forming means.
Claim 6
Dependent Claim
23 words
The intraoperative device of claim 4 wherein a gasket is disposed within the aperture to firmly but softly grip the channel forming means.
Claim 7
Dependent Claim
16 words
The intraoperative device of claim 5 wherein the gasket is formed of rubber or elastomeric material.
Claim 8
Dependent Claim
17 words
The intraoperative device of claim 1 wherein the shapable intermediate section is formed of a malleable metal.
Claim 9
Dependent Claim
23 words
The intraoperative device of claim 7 wherein the malleable metal is selected from the group consisting of aluminum, copper and malleable alloys thereof.
Claim 10
Dependent Claim
18 words
The intraoperative device of claim 7 wherein the malleable metal is in the form of rod or cable.
