Abstract: Techniques for three-dimensional product reconstruction using multiple images collected at checkout lanes are disclosed herein. An example method includes capturing, by a barcode reader associated with a point of sale (POS) workstation, first image data associated with each of a plurality of products passing through a product scanning region of the POS workstation; analyzing barcode data from the first image data captured by the barcode reader to identify each product of the plurality of products passing through the product scanning region of the POS workstation; capturing, by one or more color cameras associated with the POS workstation, second image data associated with the identified product, of the plurality of products passing through the product scanning region of the POS workstation; and generating, by a processor, a textured three-dimensional mesh reconstruction for the identified product based on the second image data associated with the identified product.

Abstract: Techniques related to validating an image based 3D model of a scene are discussed. Such techniques include detecting an object within a captured image used to generate the scene, projecting the 3D model to a view corresponding to the captured image to generate a reconstructed image, and comparing image regions of the captured and reconstructed images corresponding to the object to validate the 3D model.

Abstract: A thrombectomy system includes a frame having plurality of struts joined at an apex, a netting coupled to the plurality of struts, a pestle moveable relative to the frame and configured and arranged to macerate a clot within a vessel, adherent to its walls and against a portion of the apex of the frame.

Abstract: A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.

Abstract: A three-dimensional representation of a scene captured in an action shot base video may be determined. The three-dimensional representation may identify a camera pose. A representation of an object may be determined from a multi-view representation of the object that includes images of the object and that is navigable in one or more dimensions. An action shot video of the scene that includes a rendering of the object determined based on the representation and the camera pose may be generated.

Abstract: The present invention relates to a device for endoscopy or endosonography-guided transluminal interventions whereby two luminal structures in the body may be drawn toward each other and a fluid conduit formed in between. The device may have a hollow central member to which is coupled a distal retention member and in one embodiment a proximal retention member. The retention members may each be positioned inside one of the luminal structures and expanded from a first condition to an expanded second condition having an increased radius. The length of the central member may be shortened and its diameter expanded to approximate the two retention members and thereby the luminal structures.

Abstract: Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, engaging an interventional device of a catheter system with clot material in a blood vessel and withdrawing the interventional device and the portion of the clot material through a guide catheter. In some embodiments, the catheter system can include an attachment/valve member coupled to a proximal portion of the guide catheter, and the method can include unsealing the attachment/valve member to facilitate withdrawing the interventional device through the attachment/valve member without significant retention of clot material within the attachment/valve member. The method can further include resealing and aspirating the guide catheter before advancing another interventional device to the clot material to again engage and remove clot material from the blood vessel.

Abstract: Devices and methods for performing a transseptal puncture procedure using a device which includes either an untapered or tapered blunt end cannula disposed in an introducer carrying a sharp guidewire disposed longitudinally through the lumen of the blunt cannula, and a blunt end dilator wherein the guidewire is flexible and has an atraumatic shape at its tip. The cannula gives the more flexible introducer a defined shape and steerabilty allowing an ordinarily skilled physician to easily access a selected location on the septal wall of the heart for transseptal puncture and introducer placement thereacross without employing an exposed sharp end needle during the procedure.

Abstract: A method is disclosed for removing a vascular occlusion, such as a clot, from a blood vessel. A tubular sheath is inserted into the vessel and a self-expanding Nitinol mesh filter is deployed from a distal end of the tubular sheath at a location proximal to a clot. An inner catheter is advanced through the tubular sheath and through the mesh filter for contacting the clot. An expandable agitation element is provided along a distal end portion of the inner catheter for cutting or chopping the clot, thereby facilitating removal of the clot and improving blood flow through the vessel. Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs.

Abstract: A magnet-assisted suture grasper for grasping a magnetic suture is provided. The magnet-assisted suture grasper includes a suture retrieval needle, a retriever body, a grasper wire, a grasper arm, and a grasper magnet. Translation of the retriever body within a needle lumen of the suture retrieval needle in a first direction causes the grasper arm to move from a first position to a second position, thereby exposing the grasper magnet from the needle lumen and allowing contact between the grasper magnet and a magnetic suture attracted thereto. Translation of the retriever body within the needle lumen in a second direction opposite the first direction causes the grasper arm to move from the second position to the first position, thereby sequestering the grasper magnet and grasping the magnetic suture within the needle lumen.
