Abstract: A scraping device has a scissor-like construction with two blades. Each blade can extend in a same plane as handle of the device. One of the blades is more dull than the other, the dull blade adapted to abut a part of the human body without causing any permanent physical change thereto, and the other being sharper than the dull blade which is designed to cut or remove part of the body. In some embodiments, one or both blades are rotatable in a plane which is normal to the direction of rotation of the handles relative to each other. In other embodiments, the blades are fixed at an angle relative to the handles and/or direction of movement of the handles. The dull blade may be inline with the handles while the sharp blade and/or cutting edge of the sharp blade is out of line therewith.

Abstract: A radially expandable trocar, port or cannula system is provided for use in minimally invasive surgeries. The cannula creates a port access with an initial small internal diameter. The passage of the cannula devices is defined by a plurality of elongate rigid members. A number of mechanisms are provided for expanding the passage of the cannula devices, by moving the plurality of elongate rigid members towards a larger radial location, thereby creating a larger internal diameter for the port. The elongate rigid members can be prevented from unintended movement when the system is at the un-expanded state, during expansion and when it is expanded to the desired larger diameter. Exemplary embodiments include methods of preventing gas loss from the tissue that would occur through the gaps created during expansion.

Abstract: The device disclosed herein is used to the remove a thrombus from the vasculature. It includes an aspiration catheter and a thrombus retrieval device that extends through the lumen of the aspiration catheter. An expandable braided assembly extends over a distal region of the retrieval device, and an activation wire extends through the lumen of the retrieval device to attach to and control the expansion of the braided assembly. Applying tension to the activation wire causes the braided assembly to expand to a diameter of the practitioner's choosing. For example, the practitioner may apply a first level of tension to the activation wire to deploy the braided assembly to a first diameter and then later change the diameter by applying a different level of tension. The expanded braided assembly contacts the thrombus and is pulled proximally toward the aspiration catheter to assist in thrombus removal.

Abstract: 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.
