Abstract
Abstract An apparatus for thermal treatment of tissue, includes an outer member having a frame dimensioned for engagement with the hand of a surgeon and an elongated portion connected to the frame and extending distally therefrom. The elongated portion defines a longitudinal axis and has an axial opening. An electromagnetic probe assembly is releasably mounted to the outer member. The electromagnetic probe assembly includes a handle and an electromagnetic probe connected to the handle. The electromagnetic probe is at least partially positionable within the axial opening of the elongated portion and is adapted for reciprocal longitudinal movement therewithin between a non-deployed position and a deployed positions. A manually operable release member releasably mounts the electromagnetic probe assembly to the outer member. The release member is dimensioned and positioned for manual manipulation to move between a first position engaging the electromagnetic probe assembly and preventing release thereof from the outer member, and a second position releasing the electromagnetic probe assembly to thereby facilitate assembly and disassembly of the electromagnetic probe assembly with respect to the outer member.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
174 words
An apparatus for thermal treatment of tissue, which comprises: an outer member including a frame dimensioned for engagement with the hand of a surgeon and an elongated portion connected to the frame and extending distally therefrom, the elongated portion defining a longitudinal axis and having an axial opening; an electromagnetic probe assembly releasably mounted to the outer member, the electromagnetic probe assembly including a handle and an electromagnetic probe connected to the handle, the electromagnetic probe at least partially positionable within the axial opening of the elongated portion and adapted for reciprocal longitudinal movement therewithin between a non-deployed position and a deployed position; and a manually operable release member for releasably mounting the electromagnetic probe assembly to the outer member, the release member dimensioned and positioned for manual manipulation to move between a first position engaging the electromagnetic probe assembly and preventing release thereof from the outer member, and a second position releasing the electromagnetic probe assembly to thereby facilitate assembly and disassembly of the electromagnetic probe assembly with respect to the outer member.
Claim 2
Independent Claim
174 words
An apparatus for thermal treatment of tissue, which comprises: an outer member including a frame dimensioned for engagement with the hand of a surgeon and an elongated portion connected to the frame and extending distally therefrom, the elongated portion defining a longitudinal axis and having an axial opening; an electromagnetic probe assembly releasably mounted to the outer member, the electromagnetic probe assembly including a handle and an electromagnetic probe connected to the handle, the electromagnetic probe at least partially positionable within the axial opening of the elongated portion and adapted for reciprocal longitudinal movement therewithin between a non-deployed position and a deployed position; and a manually operable release member for releasably mounting the electromagnetic probe assembly to the outer member, the release member dimensioned and positioned for manual manipulation to move between a first position engaging the electromagnetic probe assembly and preventing release thereof from the outer member, and a second position releasing the electromagnetic probe assembly to thereby facilitate assembly and disassembly of the electromagnetic probe assembly with respect to the outer member.
Claim 3
Dependent Claim
19 words
The apparatus according to claim 1 wherein the release member is mounted to the frame of the outer member.
Claim 4
Dependent Claim
25 words
The apparatus according to claim 2 wherein the release member is rotatable about the longitudinal axis to move between the first and second positions thereof.
Claim 5
Dependent Claim
40 words
The apparatus according to claim 3 wherein the release member defines a central opening for reception of a portion of the handle of the electromagnetic probe assembly, the portion of the handle dimensioned for reciprocal longitudinal movement through the opening.
Claim 6
Dependent Claim
30 words
The apparatus according to claim 4 wherein the handle of the electromagnetic probe assembly includes a handle extension, the handle extension received within the central opening of the release member.
Claim 7
Dependent Claim
18 words
The apparatus according to claim 5 wherein the release member is normally biased to the first position thereof.
Claim 8
Dependent Claim
62 words
The apparatus according to claim 6 wherein the release member defines an inner cam surface adjacent the opening and wherein the handle extension of the handle defines a corresponding outer cam surface, the outer cam surface cooperating with the inner cam surface upon advancement of the handle extension within the release member to move the release member to the second position thereof.
Claim 9
Dependent Claim
82 words
The apparatus according to claim 7 wherein the handle extension defines an outer rail, the outer rail having the outer cam surface at a distal end thereof and defining an abutment surface at a proximal end thereof, the abutment surface dimensioned and configured to engage the release member to prevent removal of the electromagnetic probe assembly from the outer member when the release member is in the first position thereof and the electromagnetic probe is assembled with respect to the outer member.
Claim 10
Dependent Claim
30 words
The apparatus according to claim 8 wherein the handle extension includes first and second diametrically opposed outer rails and wherein the release member includes first and second inner cam surfaces.
Claim 11
Dependent Claim
41 words
The apparatus according to claim 8 wherein the frame of the outer member includes at least one longitudinal recess dimensioned for reception of the one outer rail to prevent rotational movement of the electromagnetic probe assembly relative to the outer member.
Claim 12
Dependent Claim
39 words
The apparatus according to claim 1 including a ratchet and associated pawl mechanism for permitting controlled incremental movement of the electromagnetic probe assembly toward the deployed position while preventing movement of the electromagnetic probe assembly toward its non-deployed position.
Claim 13
Dependent Claim
39 words
The apparatus according to claim 11 including a manually engageable release trigger depending from the frame, the release trigger movable to disengage the ratchet and associated pawl mechanism thereby permitting movement of the electromagnetic probe toward the non-deployed position.
Claim 14
Dependent Claim
17 words
The apparatus according to claim 12 wherein the electromagnetic probe is normally biased to the non-deployed position.
Claim 15
Dependent Claim
15 words
The apparatus according to claim 1 wherein the electromagnetic probe includes a radio frequency electrode.
Claim 16
Dependent Claim
45 words
The apparatus according to claim 14 wherein the electromagnetic probe defines an axial channel for passage of fluids, and at least one opening extending through an outer wall of the probe in fluid communication with the axial channel to permit exit of the fluids therefrom.
Claim 17
Dependent Claim
20 words
The apparatus according to claim 15 including a source of fluid communication with the axial channel of the electromagnetic probe.
Claim 18
Dependent Claim
21 words
