Abstract: A drive system including a bit with a bit end configured to provide targeted frictional engagement with a fastener. The bit end has an outer leading wall tapered with respect to the bit end longitudinal axis at a leading wall angle selected from leading wall angle values ranging within a leading wall angle tolerance band and the fastener has an inner recess wall tapered with respect to the fastener longitudinal axis at a recess wall angle selected from recess wall angle values ranging within a recess wall angle tolerance band, wherein the leading wall angle values within the leading wall angle tolerance band and the recess wall angles values within the recess wall angle tolerance band do not overlap when the outer leading wall contacts the inner pilot recess wall at a targeted focal area to achieve a desired level of frictional engagement between the pilot end and the fastener.

Abstract: A method and apparatus to generate a planar representation of a longitudinally extending 360 degree continuous view within a body cavity of a patient is disclosed comprising advancing a portion of an imaging device into the body cavity of the patient, the imaging device having an image capture mechanism disposed on a distal end thereof configured to capture at least a 360 degree view of the inside of the body cavity. Further comprising withdrawing the imaging device at a controlled rate from the patient while simultaneously coordinating and generating 360 degree view image data from the imaging device and transmitting the image data from the imaging device to an image processor. The method further comprising processing the image data to produce a planar longitudinally continuous 360 degree view of the body cavity.

Abstract: A serpentine device having a proximal end and a distal end comprising a series of discs arrayed in succession and on center along a common, neutral axis, wherein the discs comprise a first and second surface; and at least one flexible interconnect extending between and connecting each disc to any succeeding disc according to a pre-determined connection configuration, wherein the interconnects are indirectly connected to one another through the discs and configured to provide torsional and bending support to each of the discs connected thereto under an applied load, thus achieving a continuum of flexibility along an entire length of the serpentine device, as well as to facilitate the torquability of the serpentine device. The serpentine device may further comprise a bendable member and at least one transfer element configured to perform one or more transfer functions, namely the transfer of energy, work, fluid, electricity, light energy, sound energy, matter, etc.

Abstract: A miniaturized utility device having integrated optical capabilities for use on a high aspect ratio system, wherein the miniaturized utility device comprises: (a) a micro camera comprising a solid state micro imaging device including, as an integral structure, an imaging array electrically coupled to a conductive pad, wherein the solid state imaging device further includes at least one utility aperture passing therethrough, and a lens optically coupled to the imaging array; and (b) a micro utility instrument configured for coordinated operation with the imaging device at a common local site, wherein the micro utility instrument is configured to perform a designated function viewable, preferably in real-time, via a camera image generated by the micro camera.

Abstract: A miniaturized imaging device and method of viewing small luminal cavities are described. The imaging device can be used as part of a catheter, and can include a lens, an SSID including an imaging array optically coupled to the lens; an umbilical including a conductive line; and an adaptor configured to support the lens and provide electrical communication between the SSID and conductive line. Alternatively, the adaptor can be a rigid adaptor configured to provide electrical communication between the SSID and the conductive line through a conductive path. The conductive path can be configured along multiple contiguous surfaces of the adaptor such that the SSID is electrically coupled to the conductive path at a first surface, and the conductive line is electrically coupled to the conductive path at a second surface.
