Abstract

A biopsy device which is compatible for use with a magnetic resonance imaging machine. The device includes a non-metallic elongated substantially tubular needle having a distal end for insertion within tissue, a proximal end, and a longitudinal axis therebetween. The needle includes right and left members on either side of the longitudinal axis, where the right and left members each have upper and lower ends including a series of alternating male and female portions. The male portions of the right member mate with the female portions of the left member, and the male portions of the left member mate with the female portions of the right member to securely attach the two members together. The device further includes a port on the elongated needle for receiving a tissue sample.

Claims

1. A biopsy device which is compatible for use with a magnetic resonance imaging machine, said device comprising:

a. a non-metallic elongated substantially tubular needle having a distal end for insertion within tissue, a proximal end, and a longitudinal axis therebetween, said needle comprising right and left members on either side of said longitudinal axis, said right and left members each having upper and lower ends comprising a series of alternating male and female portions, wherein said male portions of said right member mate with said female portions of said left member and said male portions of said left member mate with said female portions of said right member to securely attach said two members together; and

b. a port on said elongated needle for receiving a tissue sample.

2. The device of claim 1 wherein said needle comprises a thermoplastic.

3. The device of claim 1 wherein said needle comprises a glass fiber reinforced polymer resin.

4. The device of claim 1 further including a sleeve disposed over said needle.

5. The device of claim 4 wherein said sleeve comprises high strength shrink fitted tubing.

6. The device of claim 1 wherein adhesive is disposed on said upper and lower ends of said needle for attachment of said right and left members.

7. The device of claim 1 wherein said needle has a longitudinal lumen extending therein, and said lumen having a liner extending therethrough.

8. A biopsy device which is compatible for use with a magnetic resonance imaging machine, said device comprising:

a. a handle and a non-metallic elongated substantially tubular needle having a proximal end attached to said handle, a sharp distal end for insertion within tissue, and a longitudinal axis therebetween;

b. said needle comprising right and left members on either side of said longitudinal axis, said right and left members each having upper and lower ends comprising a series of alternating male and female portions, wherein said male portions of said right member mate with said female portions of said left member and said male portions of said left member mate with said female portions of said right member to securely attach said two members together; and

c. a means for obtaining a tissue sample within said elongated needle.

9. The device of claim 8 wherein said needle comprises a thermoplastic.

10. The device of claim 8 wherein said needle comprises a glass fiber reinforced polymer resin.

11. The device of claim 8 further including a sleeve disposed over said needle.

12. The device of claim 11 wherein said sleeve comprises high strength shrink fitted tubing.

13. The device of claim 8 wherein adhesive is disposed on said upper and lower ends of said needle for attachment of said right and left members.

14. The device of claim 8 wherein said needle has a longitudinal lumen extending therein, and said lumen having a liner extending therethrough.

15. A biopsy device which is compatible for use with a magnetic resonance imaging machine, said device comprising:

a. a handle and a non-metallic elongated substantially tubular needle having a proximal end attached to said handle, a sharp distal end for insertion within tissue, and a longitudinal axis therebetween comprising a lumen, said needle further including a port for receiving a tissue sample;

b. said needle comprising right and left members on either side of said longitudinal axis, said right and left members each having upper and lower ends comprising a series of alternating male and female portions, wherein said male portions of said right member mate with said female portions of said left member and said male portions of said left member mate with said female portions of said right member to securely attach said two members together; and

c. a cutter for obtaining a sample of tissue which is disposed within said port.

16. The device of claim 15 wherein said needle comprises a thermoplastic.

17. The device of claim 15 wherein said needle comprises a glass fiber reinforced polymer resin.

18. The device of claim 15 further including a sleeve disposed over said needle.

19. The device of claim 18 wherein said sleeve comprises high strength shrink fitted tubing.

20. The device of claim 15 wherein adhesive is disposed on said upper and lower ends of said needle for attachment of said right and left members.
