Abstract

A method includes percutaneously accessing a patient via a cannula, such that a distal end of the cannula is disposed substantially adjacent a tumor associated with a bone of the patient. A composition of the tumor is modified via a medical device movably disposed within the cannula. At least a portion of the tumor is removed through the cannula. The modifying is performed during a first time period and the removing is performed during a second time period. At least a portion of the first time period overlaps with at least a portion of the second time period.

Claims

1. A method, comprising:

percutaneously accessing a patient via a cannula such that a distal end of the cannula is disposed substantially adjacent a tumor associated with a bone of the patient;

modifying a composition of the tumor via a medical device movably disposed within the cannula; and

removing at least a portion of the tumor through the cannula,

the modifying being performed during a first time period,

the removing being performed during a second time period, at least a portion of the first time period overlaps with at least a portion of the second time period.

2. The method of claim 1, wherein the percutaneously accessing includes percutaneously accessing an interior of the bone, the modifying and the removing being performed on the tumor disposed within the interior of the bone.

3. The method of claim 1, wherein the removing includes suctioning the portion of the tumor through the cannula.

4. The method of claim 1, wherein the removing includes inserting into the cannula a second medical device configured to provide a suctioning force to remove the portion of the tumor.

5. The method of claim 1, wherein:

the modifying includes dissolving at least a portion of the tumor with an agent.

6. The method of claim 1, wherein:

the modifying includes dissolving at least a portion of the tumor with an agent, the agent being at least one from the group of an ethanol and a chymopapain.

7. The method of claim 1, wherein the modifying includes injecting the tumor with a marker via the medical device, the method further comprising:

determining a location of the tumor within the body of the patient based on a position of the marker, the determining being performed externally from the patient and before the removing.

8. The method of claim 1, wherein:

the modifying being performed through a first channel of the cannula; and

the removing being performed through a second channel of the cannula different from the first channel of the cannula.

9. An apparatus, comprising:

a cannula including a proximal end portion and a distal end portion, the cannula configured to percutaneously access a body of a patient such that the distal end portion of the cannula is disposed substantially adjacent a bone; and

a first medical device configured to be received within the cannula, the first medical device configured to modify a composition of a tumor associated with the bone,

the cannula being further configured such that at least a portion of the tumor can be communicated from the distal end portion of the cannula to the proximal end portion of the cannula after the composition of the tumor has been modified by the first medical device.

10. The apparatus of claim 9, wherein:

the first medical device is configured to modify the composition of the tumor during a first time period,

the cannula is configured such that at least the portion of the tumor is communicated during a second time period, and

at least a portion of the first time period overlaps with at least a portion of the second time period.

11. The apparatus of claim 9, wherein:

the first medical device includes a scoop portion, the scoop portion configured to dislodge the portion of the tumor from the bone.

12. The apparatus of claim 9, wherein:

the first medical device includes a probe, the probe configured to inject into the tumor a marker configured to identify a location of the tumor within the body of the patient.

13. The apparatus of claim 9, wherein:

the first medical device including a needle, the needle configured to inject into the tumor an agent configured to dissolve the portion of the tumor.

14. The apparatus of claim 9, further comprising:

a second medical device configured to be received within the cannula, the second medical device configured to provide a suctioning force such that at least a portion of the tumor is removed from the body of the patient.

15. An apparatus, comprising:

an elongate body, the elongate body including a proximal end portion and a distal end portion, the elongate body configured to percutaneously access a body of a patient such that the distal end portion of the elongate body is disposed adjacent to a tumor associated with the bone, the elongate body including a first channel and a second channel, the first channel configured to receive a medical device, the second channel configured to communicate at least a portion of the tumor from within the body of the patient to a location outside of the body of the patient.

16. The apparatus of claim 15, wherein:

the first channel configured to receive the medical during a first time period,

the second channel configured to communicate at least the portion of the tumor from within the body of the patient to the location outside of the body of the patient during a second time period,

at least a portion of the first time period overlapping with at least a portion of the second time period.

17. The apparatus of claim 15, further comprising:

the medical device, the medical device including a scoop portion, the scoop portion configured to dislodge at least the portion of the tumor from the bone, the second channel configured to communicate the dislodged portion of the tumor from within the body of the patient to a location outside of the body of the patient.

18. The apparatus of claim 15, further comprising:

the medical device, the medical device including a needle, the needle configured to inject into the tumor an agent configured to dissolve at least the portion of the tumor, the second channel configured to communicate the dissolved portion of the tumor from within the body of the patient to a location outside of the body of the patient.

19. The apparatus of claim 15, further comprising:

the medical device, the medical device being a probe, the probe configured to inject into the tumor a marker configured to identify a location of the tumor within the body of the patient.

20. The apparatus of claim 15, further comprising:

the medical device, the medical device being a first medical device; and

a second medical device different from the first medical device, the first channel configured to receive the first medical device, the second channel configured to receive the second medical device, the second medical device configured to remove at least the portion of the tumor from within the body of the patient to a location outside of the body of the patient.

21. The apparatus of claim 15, further comprising:

the medical device, the medical device being a first medical device; and

a second medical device different from the first medical device, the first channel configured to receive the first medical device, the second channel configured to receive the second medical device, the second medical device configured to remove at least the portion of the tumor from within the body of the patient to a location outside of the body of the patient, the second medical device configured to provide a suctioning force.
