Abstract
Surgical systems and methods for administering an ablation treatment and other therapeutic or diagnostic protocols to a patient tissue involve a flexible stabilizer mechanism having an inner recess and an ablation mechanism coupled with the stabilizer mechanism.
Core Innovation
The invention relates to a surgical system for administering a lesion forming treatment to patient tissue. The system includes a housing with an outer membrane and an inner ribcage surrounding an inner recess, and one or more ablation elements disposed on the inner ribcage.
A vacuum supply is configured to deliver suction through the inner recess to draw a portion of the patient tissue into the inner recess. The inner ribcage permits movement of a first wall and a second wall upon application of a vacuum, and the one or more ablation elements are adjustable in response to movement of the first wall and the second wall to accommodate a variety of tissue thicknesses.
In a further embodiment, the housing further includes a web assembly, and when tissue is drawn into the inner recess upon application of a vacuum, the web assembly is drawn into the inner recess. The vacuum supply draws the tissue into the inner recess and into proximity with the one or more ablation elements, and the described system further includes temperature sensing, cooling and irrigation lumens, and a power source assembly configured to deliver energy to the ablation element.
Claims Coverage
The provided independent claims cover 2 inventive features. The inventive scope centers on vacuum-driven tissue capture in an inner recess, movement of an inner ribcage, and adjustable ablation elements to accommodate tissue thickness, with an additional web assembly feature that draws tissue into proximity with the ablation elements.
Vacuum suction tissue capture with movable inner ribcage for thickness accommodation
A surgical system including a housing having an outer membrane, an inner ribcage, one or more ablation elements, and an inner recess, with suction through the inner recess to draw tissue into the inner recess; the inner ribcage permits movement of parallel first and second walls upon application of a vacuum; the one or more ablation elements are adjustable in response to movement of the first wall and the second wall to accommodate a variety of tissue thicknesses.
Web assembly drawn into the inner recess to position tissue in proximity to ablation elements under vacuum
A surgical system including a housing having an outer membrane, an inner ribcage, one or more ablation elements, an inner recess, and a web assembly; suction through the inner recess to draw tissue into the inner recess; the inner ribcage permits movement of parallel first and second walls upon application of a vacuum; when tissue is drawn into the inner recess upon application of a vacuum, the web assembly is drawn into the inner recess, and the vacuum supply draws tissue into proximity with the one or more ablation elements.
Across the independent claims, the central claimed inventive concept is vacuum suction to draw tissue into an inner recess, combined with an inner ribcage having parallel walls that move under vacuum to adjust the one or more ablation elements so the system accommodates a variety of tissue thicknesses, with an additional web assembly feature that is drawn into the inner recess to position tissue in proximity to the ablation elements.
Stated Advantages
Accommodate a variety of tissue thicknesses by adjusting the one or more ablation elements in response to movement of the inner ribcage walls.
Draw tissue into proximity with the one or more ablation elements for administering a lesion forming treatment.
Documented Applications
Lesion forming treatment to patient tissue using vacuum suction and ablation elements configured for proximity to captured tissue.
Administering a lesion forming treatment to patient tissue using a surgical system with vacuum suction and ablation elements.
