Abstract
Abstract In a method for removing a myoma, a distal end portion of a tubular member is inserted through laparoscopic trocar sleeve disposed in the patient's abdomen. The distal end portion of the tubular member is inserted into the myoma tissues to form a core thereof inside the tubular member. The myoma core is fragmented via an energizable laparoscopic instrument and the fragments are aspirated from the tubular coring member. The tubular member may be provided along a distal edge with a cauterizing element for facilitating the insertion of the distal end portion of the tubular member into the myoma.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
157 words
A method for removing a myoma, comprising the steps of: providing a laparoscopic trocar sleeve and a tubular member provided along a distal edge with a cauterizing element; lifting a woman's abdominal wall; disposing said trocar sleeve in the lifted abdominal wall; inserting said tubular member through said trocar sleeve so that said distal end contacts a myoma in the woman's uterus; upon contact of said distal edge with said myoma, moving said tubular member further in a distal direction and into said myoma, thereby forming a core of myoma tissues inside said tubular member; during said step of moving, energizing said cauterizing element to enable said cauterizing element to cut through said myoma; upon attaining a predetermined depth in said myoma, terminating said steps of moving and energizing; and upon termination of distal movement of said tubular member, removing said core of myoma tissues in a proximal direction through said tubular member and said trocar sleeve.
Claim 2
Independent Claim
157 words
A method for removing a myoma, comprising the steps of: providing a laparoscopic trocar sleeve and a tubular member provided along a distal edge with a cauterizing element; lifting a woman's abdominal wall; disposing said trocar sleeve in the lifted abdominal wall; inserting said tubular member through said trocar sleeve so that said distal end contacts a myoma in the woman's uterus; upon contact of said distal edge with said myoma, moving said tubular member further in a distal direction and into said myoma, thereby forming a core of myoma tissues inside said tubular member; during said step of moving, energizing said cauterizing element to enable said cauterizing element to cut through said myoma; upon attaining a predetermined depth in said myoma, terminating said steps of moving and energizing; and upon termination of distal movement of said tubular member, removing said core of myoma tissues in a proximal direction through said tubular member and said trocar sleeve.
Claim 3
Dependent Claim
69 words
The method defined in claim 1 wherein said step of removing includes the steps of: providing a laparoscopic morselating instrument and a laparoscopic suction device; inserting said morselating instrument through said tubular member to the myoma core inside said tubular member; actuating said morselating instrument to fragment said core; and activating said suction device in said tubular member to aspirate myoma core fragments produced by said step of actuating.
Claim 4
Dependent Claim
34 words
The method defined in claim 2 wherein said morselating instrument is a rotary device having a cutting edge at a distal end, said step of actuating including the step of rotating said rotary device.
Claim 5
Dependent Claim
30 words
The method defined in claim 2 wherein said morselating instrument includes an optical fiber, said step of actuating including the step of transmitting a laser beam through said optical fiber.
Claim 6
Dependent Claim
33 words
The method defined in claim 2 wherein said suction device is inserted simultaneously with said morselating instrument into said tubular member, said step of activating taking place substantially during said step of actuating.
Claim 7
Dependent Claim
41 words
The method defined in claim 1 wherein said tubular member is provided along an outer surface with a distance scale, further comprising the step of visually monitoring said scale during said step of moving to ascertain attainment of said predetermined depth.
Claim 8
Dependent Claim
32 words
The method defined in claim 1 wherein said cauterizing element is a Bovie type element, said step of energizing including the step of transmitting electromagnetic radiation through organic tissues of the woman.
Claim 9
Dependent Claim
53 words
The method defined in claim 1, further comprising the steps, executed upon termination of distal movement of said tubular member, of shifting said cauterizing element in a direction substantially transverse to said tubular member and energizing said cauterizing element during said step of shifting, thereby serving to sever said core from the uterus.
