Abstract
Abstract An electrosurgery device according to an embodiment of the invention captures a lymph nodule and resects it. The lymph node is captured with a vacuum and resected it with an electrode, which minimizes bleeding and limits the potentially malignant node from coming into contact with surround tissue as it is resected and removed. This limits the potential for inadvertent cancer spread. An electrosurgery device according to an embodiment of the invention also allows several lymph nodes to be resected in a single procedure, each lymph node being easily indexed according to its nodal station and stored in a manner that limits the potential for cross-contamination. An electrosurgery device according to an embodiment of the invention further provides a collector for individually receiving resected lymph nodes. The collector may be easily detached and sent to pathology without interrupting resection of other lymph nodes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
103 words
A device for resecting selected body tissue from other body tissue at a site inside a patient and removing the selected body tissue, comprising: an electrosurgery device having an electrode that cuts through tissue to resect the selected body tissue from the other body tissue; a tubular member having a vacuum lumen that draws the selected body tissue into proximity with the electrode to permit the electrode to resect the selected body tissue from the other body tissue; and a collector having a plurality of collection chambers, each collection chamber being selectively communicable with the vacuum lumen to receive the resected body tissue.
Claim 2
Independent Claim
103 words
A device for resecting selected body tissue from other body tissue at a site inside a patient and removing the selected body tissue, comprising: an electrosurgery device having an electrode that cuts through tissue to resect the selected body tissue from the other body tissue; a tubular member having a vacuum lumen that draws the selected body tissue into proximity with the electrode to permit the electrode to resect the selected body tissue from the other body tissue; and a collector having a plurality of collection chambers, each collection chamber being selectively communicable with the vacuum lumen to receive the resected body tissue.
Claim 3
Independent Claim
130 words
A method of resecting a selected body tissue sample from other body tissue at a site inside a patient and removing the selected body tissue sample, comprising the steps of: positioning a tubular member having a lumen adjacent to the selected body tissue; creating a vacuum inside the lumen to draw the selected body tissue sample inside the lumen; drawing the selected body tissue sample inside the lumen with a vacuum; cutting through body tissue to resect the selected body tissue sample from the other body tissue with an electrosurgery device; collecting the resected body tissue sample in a collection chamber of a collector; indexing the collector to place a second collection chamber in communication with the lumen; and collecting a second body tissue sample in the second collection chamber.
Claim 4
Independent Claim
130 words
A method of resecting a selected body tissue sample from other body tissue at a site inside a patient and removing the selected body tissue sample, comprising the steps of: positioning a tubular member having a lumen adjacent to the selected body tissue; creating a vacuum inside the lumen to draw the selected body tissue sample inside the lumen; drawing the selected body tissue sample inside the lumen with a vacuum; cutting through body tissue to resect the selected body tissue sample from the other body tissue with an electrosurgery device; collecting the resected body tissue sample in a collection chamber of a collector; indexing the collector to place a second collection chamber in communication with the lumen; and collecting a second body tissue sample in the second collection chamber.
Claim 5
Dependent Claim
26 words
The method of claim 2 , including the further step of aspirating the selected body tissue from the patient out of another end of the lumen.
Claim 6
Dependent Claim
32 words
The method of claim 2 , including the further step of drawing the selected body tissue with the vacuum through a compliant port that maintains a seal with the selected body tissue.
Claim 7
Dependent Claim
23 words
The method of claim 2 , wherein the step of collecting the resected body tissue includes the further step of collecting resection byproducts.
Claim 8
Independent Claim
116 words
A device for resecting a selected body tissue sample from other body tissue at a site inside a patient and removing the selected body tissue sample, comprising: electrosurgery means for resecting the selected body tissue sample from the other body tissue; vacuum directing means for drawing the selected body tissue sample into proximity with the electrosurgery means to permit the electrosurgery means to resect the selected body tissue sample from the other body tissue; and collection means for receiving the resected body tissue, the collection means configured with a plurality of collection storage means each configured to be in selective communication with the vacuum directing means and further configured to each store a body tissue sample.
Claim 9
Independent Claim
116 words
A device for resecting a selected body tissue sample from other body tissue at a site inside a patient and removing the selected body tissue sample, comprising: electrosurgery means for resecting the selected body tissue sample from the other body tissue; vacuum directing means for drawing the selected body tissue sample into proximity with the electrosurgery means to permit the electrosurgery means to resect the selected body tissue sample from the other body tissue; and collection means for receiving the resected body tissue, the collection means configured with a plurality of collection storage means each configured to be in selective communication with the vacuum directing means and further configured to each store a body tissue sample.
Claim 10
Dependent Claim
30 words
The device of claim 1 , further comprising a compliant port disposed on the tubular member at its distal end configured to maintain a seal with the selected body tissue.
Claim 11
Dependent Claim
16 words
The device of claim 7 , wherein the compliant port is configured with an adjustable aperture.
Claim 12
Dependent Claim
23 words
The device of claim 8 , wherein the adjustable aperture is resiliently adjustable in response to the size of the selected body tissue.
Claim 13
Dependent Claim
28 words
The device of claim 1 , wherein the electrode has a distal end and wherein the electrode distal end is disposed within the lumen while resecting body tissue.
Claim 14
