  • Publication number: 20240006815
    Abstract: An electrical connector includes a plug portion and a receptacle portion. The plug portion includes a plurality of conductive pins, with a portion of each conductive pin surrounded by a non-conductive post. The receptacle portion includes a plurality of conductive pins recessed into a corresponding plurality of recesses within the receptacle portion. When the plug portion is mated to the receptacle portion, the conductive pins of the plug portion are received within the recesses of the receptacle portion and electrically connected to the conductive pins of the receptacle portion. To advantageously increase creepage and clearance between pins, it is desirable for each recess to have a depth sufficient to receive both a conductive pin and a corresponding surrounding non-conductive post when the plug portion is mated to the receptacle portion.

  • Publication number: 20170020563
    Abstract: A subintimal recanalization catheter, including an elongate shaft including a first tubular member and a penetration member slidably disposed in a lumen of the first tubular member. The penetration member includes a distal tip positioned proximal of a distal nose of the first tubular member. The distal nose of the first tubular member includes a ramp and a guide wire lumen extending through the distal nose of the first tubular member. Longitudinal movement of the penetration member relative to the first tubular member causes the penetration member to contact the ramp to direct the distal tip of the penetration member away from the first tubular member.
