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.

1. A medical device for obtaining a tissue sample, the device comprising:an elongated piercing element having a lumen extending at least partially through the elongated piercing element, wherein said elongated piercing element comprises a proximal end, a distal end having a tip for piercing tissue, and a lateral tissue receiving port communicating with the lumen; an elongated cutter having a proximal end, a distal end for cutting tissue, and a body connecting the distal and proximal ends, wherein said distal end is disposed coaxially within the said lumen of said piercing element, wherein at least a portion of said body comprises a flexible member, and wherein at least a portion of said flexible member and said proximal end of the cutter are disposed outside of said lumen of said piercing element; a cutter driver for providing powered rotation of said cutter; and a frame, said frame having a proximal end removably mounted to said cutter driver, said frame having a distal end associated with said proximal end of said elongated piercing element, and said frame having a passageway extending at least partly therethrough for receiving said cutter. 2. The medical device of claim 1 wherein said frame passageway is generally arcuate.3. The medical device of claim 2 wherein said passageway forms an arc of about ninety degrees between said frame proximal end and said frame distal end.4. The medical device of claim 1 wherein said body of said cutter comprises a wound construction.5. The medical device of claim 4 wherein said body of said cutter comprises a wound wire.6. The medical device of claim 1 wherein said body of said cutter comprises a flexible polymer.7. The medical device of claim 1 further comprising an elongated tissue remover disposed slidably within said cutter to remove a tissue sample therefrom.8. The medical device of claim 7 wherein said elongated tissue remover comprises a flexible portion for sliding within a portion of said cutter disposed in said frame passageway.9. A medical device for obtaining a tissue sample, the device comprising:an elongated piercing element having a proximal end, a closed distal end with a piercing tip for piercing tissue, a lumen extending at least partially through the elongated piercing element, and a lateral tissue receiving port spaced proximally of the closed distal end and communicating with the lumen; an elongated cutter having a proximal end, a distal end for cutting tissue, and a body connecting the distal and proximal ends, wherein said distal end is disposed coaxially within the lumen of said piercing element, wherein the cutter extends proximally from the lumen of the elongated piercing element, and wherein at least a portion of the cutter extending proximally from the lumen is flexible and capable of taking on a curved shape; a cutter driver for providing powered rotation of said cutter; and a frame, said frame having a proximal end removably mounted to said cutter driver, said frame having a distal end associated with a proximal end of said elongated piercing element, and said frame having a curved passageway extending at least partly therethrough for receiving said cutter. 10. A medical device for obtaining a tissue sample, the device comprising:a generally straight, elongated piercing element having a proximal end, a closed distal end with a piercing tip for piercing tissue, a generally straight lumen, and a lateral tissue receiving port spaced proximally of the closed distal end and communicating with the lumen; an elongated cutter having a proximal end, a distal end for cutting tissue, and a body connecting the distal and proximal ends, wherein the distal end of the cutter is positionable with the lumen of the piercing element, wherein the cutter extends proximally from the lumen of the piercing element, and wherein at least a portion of the cutter extending proximally from the lumen of the piercing element is flexible and capable of taking on a curved shape; and a member disposed proximally of the proximal end of the elongated piercing element, the member having a curved passageway therein for receiving a flexible portion of the cutter.
