  • Patent number: 10220148
    Abstract: An automatic mixing device, an actuating device having integrated plunger and configured to be removably mounted to the automatic mixing device, and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that is rotatable to initiate spring decompression to drive depression of a mixing plunger seal of the automatic mixing device. Another seal located in an outer chamber of the mixing device is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

  • Patent number: 10213580
    Abstract: Apparatus and methods are described including inserting a catheter into a subject's body via a vein of the subject's groin. The catheter is advanced distally such that a distal end of the catheter is disposed inside the subject's renal vein. Respective stabilizing portions of the catheter stabilize the catheter by being in contact with inner walls of, respectively, an iliac vein of the subject, and a vena cava of the subject. Subsequently, a medical device is deployed inside the renal vein by retracting the distal end of the catheter, such that the distal end of the catheter is in a retracted state, in which the respective stabilizing portions of the catheter still stabilize the catheter by being in contact with the inner walls of, respectively, the subject's iliac vein and the subject's vena cava. Other applications are also described.
