Abstract
A device for performing a surgical procedure includes an elongated shaft extending between a proximal end and a distal end. The shaft includes an outer surface and an inner surface. An expandable member is disposed at the distal end of the shaft. The expandable member is configured to receive inflation material. At least one electrode is disposed with the inflatable member. Methods of use are disclosed.
Core Innovation
A surgical system is provided for performing a surgical procedure to ablate pathological tissue at a surgical site in a patient using an inflatable bone tamp. The inflatable bone tamp includes at least one electrode adapted to emit RF energy having a frequency sufficient for ablating the pathological tissue, and the electrode is disposed with the inflatable bone tamp. The system further includes an expandable cage incorporated into the inflatable bone tamp.
The surgical system includes a sensor to monitor the temperature of the pathological tissue effected by the RF energy. The inflatable bone tamp is connected to a liquid pumping system, which is configured to be connected to the inflatable bone tamp. A cutting instrument creates a surgical pathway for implantation of the inflatable bone tamp, and the system includes a cannula having a central longitudinal axis in the arrangement of claim coverage.
The expandable cage is configured with first, second, and third elongated members that are spaced entirely apart from one another by gaps, where each elongated member includes an outer surface, an inner surface, and two side surfaces between the outer and inner surfaces. The widths of the outer surfaces and inner surfaces are substantially greater than the widths of the side surfaces, and the widths have at least substantially a perpendicular orientation to the central longitudinal axis of the cannula.
Claims Coverage
The provided claim set contains two independent claims. Across these independent claims, the main inventive features include RF-emitting electrodes integrated with an inflatable bone tamp, an expandable cage geometry, temperature monitoring of pathological tissue affected by RF energy, and a liquid pumping system connected to the inflatable bone tamp, with a cutting instrument for creating a surgical pathway and a cannula arrangement in the first independent claim.
Rf-emitting inflatable bone tamp with expandable cage
An inflatable bone tamp comprising at least one electrode disposed with the inflatable bone tamp, the electrode adapted to emit RF energy having a frequency sufficient for ablating the pathological tissue at the surgical site, the inflatable bone tamp including an expandable cage having at least a first elongated member, a second elongated member, and a third elongated member, with defined spacing by a first gap and a second gap and defined outer, inner, and side surfaces with specified widths relative to the central longitudinal axis.
Temperature monitoring sensor for RF-affected pathological tissue
A sensor to monitor the temperature of the pathological tissue effected by the RF energy.
Surgical pathway creation for implantation
At least one cutting instrument to create a surgical pathway for implantation of the inflatable bone tamp.
Liquid pumping system connected to the inflatable bone tamp
A liquid pumping system configured to be connected to the inflatable bone tamp.
Cannula arrangement with central longitudinal axis
A cannula having a central longitudinal axis, where the inflatable bone tamp includes the expandable cage with surface width relationships at least substantially perpendicular to the central longitudinal axis of the cannula.
Across the independent claims, the inventive concept centers on a surgical system that ablates pathological tissue at a surgical site using an inflatable bone tamp with RF-emitting electrodes and an expandable cage defined by spaced elongated members and surface width relationships, combined with temperature monitoring of RF-affected tissue, a cutting instrument for a surgical pathway for implantation, and a liquid pumping system configured to connect to the inflatable bone tamp.
