Interventional deployment and imaging system
First Claim
Patent Images
1. A needle deployment and imaging system comprising:
- a sheath having a proximal end, a distal end, and a handle structure at the proximal end, wherein the sheath is open at its proximal end and at its distal end;
an imaging core removably coupled to the sheath and adapted to be inserted into the sheath through the open proximal end, removed from the sheath through the open proximal end, and reused, wherein an imaging transducer on the core extends through the open distal end of the sheath when the core is present therein and wherein the imaging transducer may be deflected when the transducer extends beyond the sheath, and wherein the imaging core further comprises a handle structure at a proximal end of the imaging core, the handle structure of the sheath being configured to mate with the handle structure of the imaging core; and
an interventional core disposed in the sheath.

Abstract
Needle deployment and imaging system includes a sheath, an imaging core, and interventional core. The imaging core and interventional core are received in first and second axial passages in the sheath and at least one of said cores will be removable and replaceable within the sheath. The imaging core may be extended from the sheath or be sealed within the first axial passage of the sheath. The interventional core will typically be advanced laterally or axially from a location near the distal end of the sheath.

14. A system for treating uterine fibroids, said system comprising:
-
a sheath having a proximal end, a distal end, and a handle structure at the proximal end, wherein the sheath is open at its proximal end and at its distal end and the sheath is adapted to be transvaginally introduced to locate the distal end in a uterus; an ultrasonic imaging core removably coupled to the sheath and having a field of view, said imaging core adapted to be inserted into the sheath through the open proximal end, removed from the sheath through the open proximal end, and sterilized for reuse, wherein an imaging transducer on the core extends through the open distal end of the sheath when the core is present therein and wherein the imaging transducer may be deflected when the transducer extends beyond the sheath, and wherein the imaging core further comprises a handle structure at a proximal end of the imaging core, the handle structure of the sheath being configured to mate with the handle structure of the imaging core; and a needle reciprocatably positioned in the sheath and having a distal end which is positionable in the field of view of the ultrasonic imaging core. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
