    Abstract: In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field.

  • Patent number: 10244927
    Abstract: Methods and apparatuses for space-optimized visualization catheters are provided. Some embodiments utilize complimentary metal-oxide-semi-conductor (“CMOS”) technology integrated into a CMOS camera train holder system that may be a stand-alone component for use with a visualization catheter, such as a baby endoscope, or may be fabricated/extruded as a part of the catheter itself. Some embodiments of apparatuses, methods, and equivalents thereto provide better direct visual feedback to the medical personnel performing the procedure while providing a similarly-sized outer diameter visualization catheter device having an increased space therein for additional lumens and equipment or by reducing the overall outer diameter of the visualization catheter.

  • Patent number: 10231782
    Abstract: A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue.

  • Patent number: 10226169
    Abstract: An endoscope with a flexible endoscope shaft has an endoscope head arranged at its distal end. The endoscope head is a sleeve, open at both end faces. Functional units, such as an optical system, a working channel, an illumination and a cooling system for the illumination are accommodated in the endoscope head. The cooling system has a heat exchanger integrally formed with the sleeve in the latter which forms a closed cooling chamber for generating a coolant flow. The illumination, which is in the form of an external conductor plate supporting an illumination means, is arranged adjacent to the distal end wall of the heat exchanger, to discharge thermal energy via the end wall of the heat exchanger to the coolant flow. The external conductor plate is mechanically supported on, or has only a minimum distance from, the heat exchanger end wall.

  • Patent number: 10206557
    Abstract: A power source apparatus and a system incorporating said power source for medical capsules are disclosed. Embodiments of the present invention allow the medical capsule to enable/disable electrical power supplied to a sub-system in the capsule device without special tools and/or skills after the medical capsule is manufactured. In one embodiment, the power source apparatus comprises a plunger responsive to a magnetic field, a spring to interact with the plunger, a battery and a control piece. The plunger is moved between first and second positions according to a magnetic field applied externally. Accordingly, the control piece enables or disables the power depending on the plunger positions. In another embodiment, a capsule system uses an electrical interconnect with pressure contacts between the power source and the capsule sub-system connecting the second circuit board to the power-output nodes.
