Abstract: A medical scope device may have a handle located at a proximal end of the medical scope device. The medical device may have a first steerable device extending from the handle to a distal end of the medical scope device and a second steerable device extending from the handle to the distal end of the medical scope device. The medical device may have a first control assembly disposed at a first location on the handle and a second control assembly disposed at a second location on the handle, offset from the first control assembly. The first control assembly may control a movement of a distal end of the first steerable device, and the second control assembly may control a movement of a distal end of the second steerable device.

Abstract: A device including a needle configured to measure portal pressure in a vein of a mammal and provide an indication of a measurement a diagnostic biomarker in a sample drawn from the vein before removing the needle is provided. Methods of providing medical data about a patient by use of a device are further provided.

Abstract: A system suitable for delivering a therapeutic agent to a target site may include a container for holding a therapeutic agent; a pressure source having pressurized fluid, the pressure source in selective fluid communication with at least a portion of the container; a catheter in selective fluid communication with the container and configured for delivery of the therapeutic agent or the pressurized fluid to a target site; and a housing configured to securely retain the container and movably support a switch, where the switch is movable between a first position and a second position, where when the switch is in the first position, delivery of the therapeutic agent is prevented while delivery of the pressurized fluid is permitted, and where when the switch is in the second position, delivery of the therapeutic agent is permitted.
