Abstract

A cryoprobe supports administration of an active agent to a location of cryogenic treatment. The cryoprobe may optionally be combined with a syringe to form a cryoprobe system; alternatively and optionally, the syringe may be external to the cryoprobe.

Claims

1. A cryosurgical probe for providing an active substance in the vicinity of a tissue, comprising:

a. an injection unit comprising a chamber for receiving the active substance, and a syringe needle in communication with said chamber for administering the active substance to the tissue; and

b. a cryoprobe unit for providing cryotherapy, said cryoprobe unit featuring a cryoneedle for insertion to the tissue.

2. The probe of claim 1, wherein said cryoprobe unit is combined with said injection unit in a single device.

3. The probe of claim 2, wherein said cryoneedle and said syringe needle are combined.

4. The probe of claim 3, wherein said injection unit comprises a syringe barrel connected to said chamber and a piston for providing the active agent to said chamber.

5. The probe of claim 4, wherein said cryoprobe unit further comprises an inner lumen for receiving cryogen and for cooling said cryoneedle, and an outer lumen for at least partially surrounding said injection unit.

6. The probe of claim 5, wherein said cryoprobe unit further comprises a longitudinal shaft for at least partially surrounding said inner lumen, said longitudinal shaft featuring at least one groove for receiving said needle.

7. The probe of claim 6, wherein said cryoprobe unit further comprises a cryotip for sealing said outer lumen, said outer lumen featuring an opening adjacent to said cryotip for said needle to emerge, said cryotip causing said needle to be splayed away from said cryotip.

8. The probe of claim 7, further comprising a plurality of injection units and a plurality of needles, wherein said plurality of needles and said plurality of injection units are controlled with a single handle.

9. The probe of claim 3, wherein said injection unit comprises a syringe barrel connected to said chamber and a piston for providing the active agent to said chamber, and wherein said cryoprobe unit further comprises an inner lumen for receiving cryogen and for cooling said cryoneedle, and an outer lumen for at least partially surrounding said chamber and said cryoneedle, such that said barrel and said piston are external to said outer lumen.

10. The probe of claim 9, wherein said cryoneedle is attached to said chamber, and said cryoneedle is displaced through movement of a handle for pushing on said chamber.

11. The probe of claim 9, wherein said cryoneedle is attached to said chamber, said cryoprobe unit further comprising a pneumatic bellows for pushing said chamber and for causing said cryoneedle to be displaced.

12. The probe of claim 9, wherein said cryoneedle is attached to said chamber, said cryoprobe unit further comprising a handle for pushing said chamber and for causing said cryoneedle to be displaced, and an extension spring attached to said chamber for pulling against displacement of said chamber.

13. A cryoprobe for treating an area of tissue with cryotherapy and an active agent, comprising at least one needle, which is substantially aligned with the axis of said cryoprobe, for being cooled with a cryogen and for administering the active agent.

14. A method of combined treatment comprising local delivery of at least one enzyme before, during or after cryotherapy at the site of said cryotherapy.

15. A method of combined treatment comprising local delivery of a vasoconstrictive agent to a site to be treated by cryosurgery before said cryosurgical treatment.

16. A method of a combined treatment comprising injection of an aqueous solution into the tissue prior to a cryosurgical treatment in order to enhance the cryo-damaging effect of said treatment.

17. A method of a combined treatment comprising the local injection of at least one radioactive element within the area of cryotreatment.
