A suturing apparatus comprises an elongated body, at least one arms movable relative to the elongated body and at least one needle movable relative to the elongated body. The arm releasably holds an end portion of a length of suture. The arm has a sharp end portion adapted to pierce an inner surface of a wall of a biological structure and pass an end portion of the suture through the inner surface. The needle is adapted to pierce the inner surface of such biological structure at a location proximal to the location where the end portion of the suture was inserted. The needle captures an end portion of the suture from the arm and draws the end portion of the suture back through the inner surface. The end of the suture is then drawn out of the biological structure by removing the elongated body.

InactiveUS7004952B2Many of complicationMany of costSuture equipmentsSurgical needlesDistal portionVia incision
A suturing device allows a physician to remotely seal an incision in a blood vessel or other biological tissue. The device comprises an elongated tubular body having a distal portion which is adapted to be inserted percutaneously through the incision and into the blood vessel. The distal portion has first and second retractable arms which extend from the distal portion of the body and releasably hold a suture within the blood vessel. First and second retractable needles, each of which is configured to catch the suture from a respective arm, are provided along the body proximal to the retractable arms. The arms and the needles are remotely movable by the physician using a handle or other control mechanism provided at a distal portion of the device. In operation, the arms are initially deployed within the blood vessel to hold the ends of the suture beyond the circumference of the tubular body. The needles are then deployed from and then retracted into the body, during which time the needles pierce the vessel wall on opposite sides of the incision, release the suture ends from the retractable arms, and pull the suture through the vessel wall. The device is particularly useful for closing an incision in an artery following a catheterization procedure. In one embodiment, the catheter sheath introducer (CSI) used to perform the catheterization procedure is left in place during the suturing procedure.

Method and apparatus for visualization of biological structures with use of 3D position information from segmentation results
A data processing methodology and corresponding apparatus for visualizing the characteristics of a particular object volume in an overall medical / biological environment receives a source image data set pertaining to the overall environment. First and second contour surfaces within the environment are established which collectively define a target object volume. By way of segmenting, all information pertaining to structures outside the target object volume are excluded from the image data. A visual representation of the target object based on nonexcluded information is displayed. In particular, the method establishes i) the second contour surface through combining both voxel intensities and relative positions among voxel subsets, and ii) a target volume by excluding all data outside the outer surface and inside the inner surface (which allows non-uniform spacing between the first and second contour surfaces). The second contour surface is used as a discriminative for the segmenting.

Virtual endoscopy
InactiveUS20080118117A1Full effectImproved angular separationSurgeryEndoscopesData setVirtual camera
A method of orienting a virtual camera for rendering a virtual endoscopy image of a lumen in a biological structure represented by a medical image data set, e.g., a colon. The method comprises selecting a location from which to render an image, determining an initial orientation for the virtual camera relative to the data set for the selected location based on the geometry of the lumen, determining an offset angle between the initial orientation and a bias direction; and orienting the virtual camera in accordance with a rotation from the initial orientation towards the bias direction by a fractional amount of the offset angle which varies according to the initial orientation. The fractional amount may vary according to the offset angle and / or a separation between a predetermined direction in the data set and a view direction of the virtual camera for the initial orientation. Thus the camera orientation can be configured to tend towards a preferred direction in the data set, while maintaining a good view of the lumen and avoiding barrel rolling effects.

Method for multi-scale meshing of branching biological structures
InactiveUS20110093243A1Good specificationIncrease computing speedMedical simulationImage enhancementLocal pressureGrid partition
A structural and functional model for a lung or similar organ is virtually defined by encoding aspects of branching passageways. Larger passageways that are visible in medical images are surface mesh fitted to the anatomical surface geometry. Smaller distal passageways, beyond a given number of branch generations, are modeled by inference as linear passages with nominal diameters and branching characteristics, virtually filling the space within the outer envelope of the organ. The model encodes finite volumetric elements for elasticity and compliance in passageway walls, and for local pressure and flow conditions in passageway lumens during respiration. The modeling can assess organ performance, help to plan surgery or therapy, determine likely particle deposition, assess respiratory pharmaceutical dosing, and otherwise represent structural and functional organ parameters.
