  • Patent number: 10874426
    Abstract: A seal assembly for use with an access apparatus includes an integral filter and evacuation port for filtering of fluids, e.g., smoke, from an operating site and removing contaminants and/or odor from the fluids for release of the filtered fluids into the ambient atmosphere. The seal assembly may be a separate subassembly or component which is releasably couplable to the access apparatus or may be integral with the access apparatus. The seal assembly defines its own flow path independent of the insufflation mechanism of the cannula assembly, and is capable of filtering fluids even in the presence of a surgical object positioned within the cannula assembly.

  • Patent number: 10814106
    Abstract: An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.

  • Patent number: 10736635
    Abstract: A device for creating a fistula between blood vessels operates in conjunction with a guidewire to locate and position itself so that it straddles both vessels and is able to draw them together. A fixing agent is released either from within the device or from an external needle, or both, into the procedural site. The fixing agent functions to hold the relative position of the two vessels, to seal the surrounding tissue so that any leaks that do occur don't spread into the tissue to create a hematoma, and to limit expansion of the fistula. After the vessels are in close proximity to each other and the fixing agent is applied, the device of the invention employs a cutting mechanism which opens a portal between the two vessels.

Initially, a retrograde entry is made into the arterial system of a patient at an entry point with a curved needle, which then exits at an exit point proximal to the entry point, with a first wire then passed through the lumen of the curved needle. From the skin exit point, a Dual-Lumen Access Director (DAD) device is advanced in the antegrade direction down the first wire in a first lumen and enters the CFA 1 lumen. A second wire is passed down a second lumen in the DAD device and follows the SFA lumen in the antegrade direction. The DAD device is removed, and a standard dilator and sheath is inserted over the second wire and the endovascular treatment begins.

  • Patent number: 10322275
    Abstract: Adaptors, cannulas, caps, tube couplers, and systems thereof provide endovascular access through an established ECLS system. Adaptors having curved or angled shafts navigate right angle side ports of standard bypass cannulas and permit hemostatic introduction and direction of an intervention device to the axial flow path of the cannula lumen and bypass system. A modified cannula having an angled side port is also provided for use as an arterial cannula. A cap having an occluding surface may be inserted into the angled side port to prevent blood from stagnating in the angled side port. A tube coupler is also provided having an access port, such as an angled access port, and may be spliced into an established bypass system for vascular access point. Multiple couplers can be used to provide multiple access points. The adaptors and occlusive cap are interchangeable with each other and with secondary circuits.

  • Patent number: 10314564
    Abstract: A system for enhanced surgical navigation including a computing device and an imaging device. The computing device is configured to import a navigation path to a target using a first data set of computed tomography images previously acquired, display the navigation path on a graphical user interface for navigation to the target and placement of a plurality of markers in tissue proximate the target, and acquire a second data set of computed tomography images including the plurality of markers. The imaging device is configured to capture fluoroscopic data of tissue proximate the plurality of markers. The computing device is further configured to register the fluoroscopic data to the second data set of computed tomography images based on marker position and marker orientation within the fluoroscopic data and marker position and orientation within the second data set of computed tomography images.

  • Patent number: 10279100
    Abstract: A seal member and outer cylinder needle (OCN) tip part for blocking, in a fluid-tight state, both external peripheral space (EPS) end parts formed between the external-peripheral-surface of an inner needle (IN) and internal peripheral surface of an OCN, for slidably holding the IN in close contact; an opening part formed on the OCN external-peripheral-surface and for intravascular communication with the EPS; an OCN connection part for communicating between the EPS and blood circuit end; an IN connection part for communicating between the IN internal space and other blood circuit end. The movable IN positioned between the projecting position where the tip part protrudes from the OCN tip and the housed position housing the tip inside the OCN. The IN punctures the blood vessel interior while holding the projecting position, and moved to the housed position after puncture allowing blood to extracorporeally circulate via the OCN and IN connection part.

  • Patent number: 10258369
    Abstract: Provided is an endoscopic surgical device and an overtube with which a surgeon can easily obtain a desired image and in which operability is high. The overtube includes a slider within an overtube body, which guides an endoscope and a treatment tool into a body cavity. An endoscope-coupled part and a treatment tool-coupled part are provided inside the slider, and the slider has a dead zone where the forward and backward movement of either the endoscope or the treatment tool does not interlock with the movement of the other and a sensing zone where the forward and backward movement of either the endoscope or the treatment tool interlocks with the movement of the other. The overtube body is configured to allow the treatment tool to rotate around an axis thereof without changing the positional relationship of the endoscope and the treatment tool with respect to the overtube body.

  • Patent number: 10244947
    Abstract: An introducer having a dilator positioned in a sheath is inserted into a first blood vessel and, thereafter, only the dilator tube is drawn out of the first blood vessel and the sheath while the sheath remains in the first blood vessel. A diagnostic instrument having an outer diameter smaller than a maximum outer diameter permitting insertion into the sheath tube is inserted into the second blood vessel, and a stenosis of the second blood vessel is diagnosed. While keeping the sheath indwelling in the first blood vessel, a therapeutic instrument or a catheter permitting the therapeutic instrument to be inserted therein, which therapeutic instrument or catheter has a maximum outer diameter permitting insertion into the sheath tube, is inserted into the second blood vessel, and the second blood vessel is treated.
