Abstract
Abstract A biopsy probe for the collection of at least one soft tissue sample from a surgical patient. The biopsy probe has a frame and an elongated piercing element having a proximal end attached to the distal end of the frame and a sharpened distal end for piercing tissue. The piercing element has a lumen extending at least partially therethrough. The probe also includes an elongated cutter disposed coaxially and slidably within the lumen of the piercing element. The cutter has a distal end for cutting a tissue sample, a proximal end and a body connecting the distal and proximal ends, wherein at least a portion of the body comprises a flexible member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
118 words
1 . A biopsy probe for the collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element having a proximal end attached to said distal end of said frame and a sharpened distal end for piercing tissue, and a lumen extending at least partially therethrough; and c. an elongated cutter disposed coaxially and slidably within said lumen of said piercing element, said cutter having a distal end for cutting a tissue sample, a proximal end and a body connecting said distal and proximal ends, wherein at least a portion of said body comprises a flexible member.
Claim 2
Dependent Claim
118 words
1 . A biopsy probe for the collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element having a proximal end attached to said distal end of said frame and a sharpened distal end for piercing tissue, and a lumen extending at least partially therethrough; and c. an elongated cutter disposed coaxially and slidably within said lumen of said piercing element, said cutter having a distal end for cutting a tissue sample, a proximal end and a body connecting said distal and proximal ends, wherein at least a portion of said body comprises a flexible member.
Claim 3
Dependent Claim
24 words
2 . A biopsy probe as recited in claim 1 wherein said frame is generally acurate between said distal end and said proximal end.
Claim 4
Dependent Claim
28 words
3 . A biopsy probe as recited in claim 3 wherein said frame forms an arc of about ninety degrees between said proximal end and said distal end.
Claim 5
Dependent Claim
22 words
4 . A biopsy probe as recited in claim 1 wherein said body of said cutter is constructed of wound steel wire.
Claim 6
Dependent Claim
22 words

Claim 7
Dependent Claim
223 words
6 . A biopsy probe for the collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element attached to the distal end of said frame, said piercing element having distal end, a proximal end and a lumen extending therethrough, said piercing element comprising a sharpened distal end for piercing tissue and a port, proximal thereto, for receiving a tissue sample; c. an elongated cutter disposed coaxially and slidably within said lumen of said piercing element, said cutter having an open distal end comprising a cutting blade, a proximal end, and a body connecting said distal and proximal ends, said body having a cutter lumen extending therethrough wherein when a tissue mass is disposed within said port of said piercing element said cutter blade slides through said port and deposits a portion of the tissue mass within said cutter lumen, at least a portion of said body of said cutter being flexible; and d. an elongated tissue remover disposed slidably within said cutter lumen, said tissue remover having a proximal end, a distal end, and a flexible remover body therebetween, whereby said distal end of said remover slides distal to said distal end of said cutter to remove a tissue sample therefrom.
Claim 8
Dependent Claim
223 words
6 . A biopsy probe for the collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element attached to the distal end of said frame, said piercing element having distal end, a proximal end and a lumen extending therethrough, said piercing element comprising a sharpened distal end for piercing tissue and a port, proximal thereto, for receiving a tissue sample; c. an elongated cutter disposed coaxially and slidably within said lumen of said piercing element, said cutter having an open distal end comprising a cutting blade, a proximal end, and a body connecting said distal and proximal ends, said body having a cutter lumen extending therethrough wherein when a tissue mass is disposed within said port of said piercing element said cutter blade slides through said port and deposits a portion of the tissue mass within said cutter lumen, at least a portion of said body of said cutter being flexible; and d. an elongated tissue remover disposed slidably within said cutter lumen, said tissue remover having a proximal end, a distal end, and a flexible remover body therebetween, whereby said distal end of said remover slides distal to said distal end of said cutter to remove a tissue sample therefrom.
