Abstract
Abstract An excisional biopsy device includes a tubular member having a window near a distal tip thereof; a cutting tool, a distal end of the cutting tool being attached near the distal tip of the tubular member, at least a distal portion of the cutting tool being configured to selectively bow out of the window and to retract within the window; and a tissue collection device externally attached at least to the tubular member, the tissue collection device collecting tissue excised by the cutting tool as the biopsy device is rotated and the cutting tool is bowed. An excisional biopsy method for soft tissue includes the steps of inserting a generally tubular member into the tissue, the tubular member including a cutting tool adapted to selectively bow away from the tubular member and an external tissue collection device near a distal tip of the tubular member; rotating the tubular member; selectively varying a degree of bowing of the cutting tool; collecting tissue severed by the cutting tool in the tissue collection device; and retracting the tubular member from the soft tissue. The tubular member may include an imaging transducer and the method may include the step of displaying information received from the transducer on a display device and the step of varying the degree of bowing of the cutting tool based upon the displayed information from the imaging transducer. Alternatively, the imaging transducer may be disposed within a removable transducer core adapted to fit within the tubular member.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
84 words
An excisional biopsy method for soft tissue, comprising the steps of: inserting a generally tubular member into the tissue, the tubular member including a cutting tool adapted to selectively bow away from the tubular member and an external tissue collection device near a distal tip of the tubular member; rotating the tubular member; selectively varying a degree of bowing of the cutting tool; collecting tissue severed by the cutting tool in the tissue collection device; and retracting the tubular member from the soft tissue.
Claim 2
Dependent Claim
84 words
An excisional biopsy method for soft tissue, comprising the steps of: inserting a generally tubular member into the tissue, the tubular member including a cutting tool adapted to selectively bow away from the tubular member and an external tissue collection device near a distal tip of the tubular member; rotating the tubular member; selectively varying a degree of bowing of the cutting tool; collecting tissue severed by the cutting tool in the tissue collection device; and retracting the tubular member from the soft tissue.
Claim 3
Dependent Claim
19 words
The method of claim 1 , wherein the rotating step is carried out by manually rotating the tubular member.
Claim 4
Dependent Claim
53 words
The method of claim 1 , wherein the tubular member further includes an imaging transducer and wherein the method further comprises the steps of: displaying information received from the transducer on a display device; and varying the degree of bowing of the cutting tool based upon the displayed information from the imaging transducer.
Claim 5
Dependent Claim
