Abstract: An excisional device for either handheld or stereotactic table use may comprise an outer sheath that may comprise a distal trough shape configured to penetrate and/or cut tissue independently or in concert with work element(s). The articulable work element(s) may comprise articulable beak(s) and may be configured to translate and/or rotate at a first rate and to cut tissue in a direction implied by placement of the trough shaped outer sheath. A first helical element or equivalent assembly may be configured to transport tissue cut by the work element(s) and/or trough, may be co-axially disposed relative to the work element(s) and may be operative to rotate at a second rotation rate that is different than the first rate. A proximal sheath may be co-axially disposed relative to the work element(s) and the first helical element, and may be configured to rotate and actuate the work element(s).

Abstract: Minimally invasive, multi-functional robotic surgical tool devices for use as lavaging, material aspiration or delivery surgical forceps, scissors or clamp or other device, consisting of a monolithic work element and open central lumen with various functional tips. Such devices may in use follow a central lumen of another device or over a wire in a longitudinal direction upon introduction to a body. Flush and vacuum transport mechanisms, imaging mechanisms or energy source mechanisms may be incorporated. Inner and outer sheaths which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks and provisions for simultaneous beak closing under rotation may be incorporated.

Abstract: A platform device for material excision or removal from vascular structures for either handheld or stereotactic table or robotics platform use may comprise a work element or elements configured to selectively open and close at least one articulable beak or scoopula configured to penetrate and remove intra-vascular materials or obstructions or follow a central lumen of another device or over a wire in a longitudinal direction. Flush and vacuum tissue transport mechanisms may be incorporated as well as single or multiple arrays of image guidance elements, directional elements, ablation elements and other interventional assistance elements. A single tube or an inner sheath and an outer sheath which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks or scoopulas and provisions for simultaneous or differential beak or scoopula closing under their differential rotation may be incorporated.

Abstract: A universal, self-contained, self-powered, compact, external vacuum source and cytology or cytology and histology collection, storage, preservation and transport system device may be configured to couple to any suitable generic biopsy or interventional device.

Abstract: An excisional biopsy and delivery device may comprise one or more rotating, penetrating and cutting rod elements. The rod elements may be configured to advance from a stored and confined first position and rotate about an axis, while being simultaneously revolved about a central axis. The rod elements may then assume a second released and expanded configuration that is operative to cut around and surround target tissue. In this manner, the rod elements are operative to move through the surrounding tissue to create a volume of revolution and to sever and capture the target tissue contained within the volume of revolution from the surrounding tissue. The severed and captured volume of revolution containing the target issue may then be removed.
