Abstract: A medical device for blood vessel detection and occlusion includes an elongated member, a sensor, and an occluder. The elongated member includes a distal portion configured and dimensioned for accessing anatomical regions. The distal portion includes a recessed area. The sensor of the device can sense a blood vessel disposed in or near the recessed area. The occluder is operatively associated with the distal portion, and it is configured for at least partially stopping the flow of blood through the blood vessel disposed within the recessed area.

Abstract: A method for necrosing target tissue within a hollow organ, comprises looping a cinching device around an outer surface of the hollow organ and coupling ends of the cinching device to one another in combination with tightening the cinching device to compress tissue of the hollow organ to occlude at least one artery supplying blood to the hollow organ and maintaining the cinching device around the hollow organ until a period of time selected to necrose the target tissue has elapsed.

Abstract: A medical device can be used to entrain biological or foreign material during a medical procedure for the fragmentation of the material. The device also can be used to remove the material safely from the body. The device has a core element with a first portion extending substantially longitudinally and a second portion wound to form at least a helical coil in the shape of cone. A flat wire can substantially wrap the first and second portions of the core element, or a wire can substantially wrap the first portion and a sheath can substantially cover the second portion.

Abstract: A device for occluding a blood vessel, comprises a blunt dissection needle and a first occlusion clip releasably mounted to a distal end of the blunt dissection needle, the first occlusion clip being biased to assume a clamped configuration in combination with a retaining element which, in a first configuration, retains the first occlusion clip in an insertion position against an outer surface of the blunt dissection needle and, in a second configuration, releases the first occlusion clip to assume the clamped configuration.

Abstract: A device for accessing a hollow organ comprises an elongated body sized for insertion into an opening into a hollow organ, the elongated body including a working channel extending therethrough from a proximal opening which, when the seal is in an operative position, is located proximally of the opening to a distal opening which, when the seal is in the operative position, opens into the hollow organ and a seal extending around a portion of the elongated body between the proximal and distal openings, the seal expanding from an insertion configuration to a sealing configuration.

Abstract: An embodiment of the invention includes providing a medical device including an elongate portion and a distal portion, the distal portion including a plurality of substantially flat crystals configured to emit energy to a common focal point. The medical device may be advanced into a body lumen, energy may be provided to a body tissue via the substantially flat crystals, and the medical device may be removed from the body lumen.

Abstract: A tissue ablation system comprises a first electrode assembly adapted for insertion into a target tissue mass within a body, the first electrode assembly including a first electrode coupled to a source of RF energy in combination with an ultrasound imaging probe movably coupled to the first electrode assembly for insertion with the first electrode assembly to a desired location relative to the target tissue mass, the probe being movable relative to the first electrode assembly between an insertion configuration in which a distal end of the probe covers a distal end of the first electrode assembly and a deployed configuration in which the distal end of the first electrode assembly is uncovered.
