摘要： Disclosed are apparatus and method for forming passage extending along a plane crossing an organ's volumetric region from an entry point to an opposing exit point at a surface of the organ, and for passing a tension member around the volumetric region by pulling the tension member from the exit point to the entry point through the passage. The apparatus can include a rigid outer tube with a tip for penetrating the organ and reach a penetration depth; an inner needle with elastic body configured to pass straightened through outer tube lumen and to partially protrude and voluntarily flex to a curved form greater than the diameter of the volumetric region; and a tension member passer with a pulling portion for engaging with portion of tension member and for pulling the tension member when withdrawn.

摘要： A surgical device comprising an elongated body, a tissue penetrating apparatus and a light projector. The elongated body can reach with distal end thereof a surface of an organ within a subject's body. The tissue penetrating apparatus can be extended from the elongated body distal end along a curved penetration path restricted to a chosen penetration plane. The light projector can generate a shaped illumination on the surface of the organ indicative of an intersection of the penetration plane with the surface of the organ.

摘要： An apparatus (500) for compressing a tumor in an organ of a body of a subject for increasing pressure within the tumor until causing ischemia and/or necrosis in the tumor. The apparatus includes an elongated body (501) for reaching surface of the organ via surgical access formed in the body. The apparatus includes a tightening mechanism (502) for tightening a tension member around a volumetric portion of organ and/or the tumor. The tightening mechanism includes a pulling member (504,505) and a force manipulator unit (513) for applying a tensioning force via the pulling member to force the tension member into a tightened state. The apparatus includes a securing mechanism (503) for securing first and second portions of the tension member for maintaining the tension member in the tightened state.

摘要： A method for treating a tumor at least partially within an organ in a subject's body. The method comprises volumetrically compressing the tumor to increase a pressure within the tumor above a threshold level to cause ischemia of the tumor; and maintaining the pressure above the threshold level for a period sufficient to cause necrosis in the tumor. The method may include passing a tension member within the organ around a predetermined volumetric region encompassing at least a portion of the tumor. The method may include tightening the tension member to cause compression of the volumetric region, thereby directly increasing a pressure within the tumor. The method may include maintaining the increased pressure such that most or all tissues of the tumor undergo ischemia and/or necrosis resulting directly from the compression caused by the tightened tension member.
