Abstract

Delivery systems, and methods using the same, having an ultrasound viewing window for improved imaging and a needle for ablation treatment of target tissues. In an embodiment, the target tissue is a fibroid within a female'"'"'s uterus. In an embodiment, the delivery system includes a rigid shaft having a proximal end, a distal end, and an axial passage extending through the rigid shaft. In an embodiment, the axial passage is configured for removably receiving the ultrasound imaging insert having an ultrasound array disposed a distal portion.

Claims

1. A system comprising:

a shaft having a proximal end, a distal end, a longitudinal axis, and an alignment feature disposed on the shaft at the distal end of the shaft; and

an ultrasound imaging insert removably disposed on the shaft and having an ultrasound array, wherein the ultrasound imaging insert is configured to engage the alignment feature on the shaft to axially and rotationally align with the shaft when the insert is being placed on the shaft, wherein the ultrasound array has a field of view with a center line which is tilted relative to the longitudinal axis and where the imaging insert may be removed and reused.

2. A system as in claim 1, further comprising a handle on the shaft and a handle on the ultrasound imaging insert, wherein the two handles join together when the insert is disposed on the shaft.

3. A system as in claim 1, further comprising a needle which is deployed from the shaft.

4. A system as in claim 3, wherein the needle is deployable within the field of the ultrasound array.

5. A system as in claim 4, wherein the needle is straight and deploys in a straight configuration.

6. A system as in claim 3, wherein the needle comprises an electrode.

7. A system as in claim 6, wherein the needle is configured to deliver radiofrequency energy.

8. A system as in claim 1, wherein the shaft is rigid.

9. A system as in claim 1, wherein the needle is hollow.

10. A system as in claim 9, wherein the hollow needle is configured for biopsy.

11. A system as in claim 9, wherein the hollow needle is configured for sampling.
