Abstract: Disclosed example robotic welding systems include: a robotic manipulator configured to manipulate a welding torch; a first input device attached to the robotic manipulator and configured to receive rotational and translational inputs; a second input device attached to the robotic manipulator and configured to receive a masking input; and a robot control system, comprising: a processor; and a machine readable storage medium comprising machine readable instructions which, when executed by the processor, cause the processor to: in response to activation of the masking input via the second input device, masking at least a portion of the inputs received via the first input device; and in response to inputs to the first input device, move the robotic manipulator according to the inputs and based on whether the inputs are masked.

Abstract: A retrieval device for removing filter devices from body cavities is provided. The retrieval device comprises at least an outer sheath, a first inner sheath, and a retrieval coil configured to coil around the outer surface of a filter device to initiate retraction. In a preferred embodiment, a second inner sheath is also provided. The two inner sheaths are configured to be slideable within the outer sheath. The second inner sheath contains a snaring wire. The snaring wire and the retrieval coil collaborate to dislodge a filter device from the vasculature, then the entire assembly is retracted and withdrawn. Particularly, the combined actions of the snaring wire and the retrieval coil facilitate the removal of filter devices that have become tilted or misaligned during deployment or treatment.
