Abstract

The present invention relates to surgical devices and related methods of use. In particular, the present invention relates to surgical devices used for contacting and treating deeply seated areas of the brain.

Claims

1. A probe device comprising:

a) a tubular central stem, wherein said tubular central stem comprises a proximal portion, a distal portion, and a distal end, wherein a plurality of suction and cutting openings are formed in said distal portion of said tubular central stem, wherein said tubular central stem is configured to allow cutting of tissue with said plurality of cutting openings, and allow aspiration of said tissue through said plurality of suction openings;

b) a probe sleeve, wherein said probe sleeve comprises a proximal portion, and a distal portion, wherein said proximal portion encloses most or all of said proximal portion of said tubular central stem;

c) at least one wire loop, wherein said at least one wire loop is operably attached to said distal end of said tubular central stem and extends beyond said distal portion of said probe sleeve, and wherein said at least one wire loop is;

i) configured for cutting tissue,

ii) configured for rotating around said distal portion of said tubular central stem, and

iii) configured to outwardly expand and contract; and

d) a loop expander and rotation motor mechanism which is operably linked to said at least one wire loop and configured to cause rotation and outward expansion of said at least one wire loop, wherein said loop expander and rotation mechanism is located in said probe sleeve

2. The probe of claim 1, wherein said at least one wire loop has a proximal portion and a distal portion, and wherein downward thrust on said proximal portion of said at least one wire by said loop expander and rotation motor mechanism causes outward expansion of said at least one wire loop.

3. The probe of claim 1, further comprising an energy generator connection, wherein said energy generator connection is attached to said probe sleeve.

4. The probe of claim 1, further comprising an irrigation fluid input port, wherein said irrigation fluid input port is attached to said probe sleeve.

5. The probe of claim 1, further comprising a vacuum port connection, wherein said vacuum port connection is attached to said probe sleeve.

6. The probe of claim 1, further comprising a cutting motor mechanism, wherein said cutting motor mechanism is attached to said tubular central stem.

7. The probe of claim 1, further comprising a loop swivel attachment, wherein said at least one wire loop is operably attached to said distal end of said tubular central stem via said loop swivel attachment.

8. The probe of claim 1, wherein said at least one wire loop expands out in a half-circle or egg-beater shape.

9. The probe of claim 1, wherein said at least one wire loop comprises two, three, four, five, or six wire loops.

10. A system comprising:

a) a probe device comprising;

i) a tubular central stem, wherein said tubular central stem comprises a proximal portion, a distal portion, and a distal end, wherein a plurality of suction and cutting openings are formed in said distal portion of said tubular central stem, wherein said tubular central stem is configured to allow cutting of tissue with said plurality of cutting openings, and allow aspiration of said tissue through said plurality of suction openings;

ii) a probe sleeve, wherein said probe sleeve comprises a proximal portion, and a distal portion, wherein said proximal portion encloses most or all of said proximal portion of said tubular central stem;

iii) at least one wire loop, wherein said at least one wire loop is operably attached to said distal end of said tubular central stem and extends beyond said distal portion of said probe sleeve, and wherein said at least one wire loop is;

A) configured for cutting tissue,

B) configured for rotating around said distal portion of said tubular central stem, and

C) configured to outwardly expand and contract; and

iv) a loop expander and rotation motor mechanism which is operably linked to said at least one wire loop and configured to cause rotation and outward expansion of said at least one wire loop, wherein said loop expander and rotation mechanism is located in said probe sleeve; and

b) at least one additional component selected from the group consisting of;

i) an energy generating component,

ii) an irrigation supply component;

iii) a system controller component;

iv) a cannula, wherein said probe is configured to fit through said cannula; and

v) a mounting mechanism.

11. The system of claim 10, wherein said energy generating component comprises an RF generating component.

12. The system of claim 10, wherein said probe is inserted through said cannula.

13. The system of claim 10, wherein said at least one wire loop has a proximal portion and a distal portion, and wherein downward thrust on said proximal portion of said at least one wire by said loop expander and rotation motor mechanism causes outward expansion of said at least one wire loop.

14. The system of claim 10, further comprising an energy generator connection, wherein said energy generator connection is attached to said probe sleeve.

15. The system of claim 10, further comprising an irrigation fluid input port, wherein said irrigation fluid input port is attached to said probe sleeve.

16. The system of claim 10, further comprising a vacuum port connection, wherein said vacuum port connection is attached to said probe sleeve.

17. The system of claim 10, further comprising a cutting motor mechanism, wherein said cutting motor mechanism is attached to said tubular central stem.

18. The system of claim 10, further comprising a loop swivel attachment, wherein said at least one wire loop is operably attached to said distal end of said tubular central stem via said loop swivel attachment.

19. The system of claim 10, wherein said at least one wire loop expands out in a half-circle or egg-beater shape.

20. The system of claim 10, wherein said at least one wire loop comprises two, three, four, five, or six wire loops.
