Catheter Guide Means Patents (Class 600/434)
  • Patent number: 11998284
    Abstract: A guide sheath includes ports at a handle portion through which flexible endoscopic tools may be advanced until they emerge from corresponding ports at a distal tip of the guide sheath. The guide sheath includes a position sensor at its distal tip that is compatible with an image guided surgery (IGS) system, such that a virtual view of the distal tip's position relative to a surgical site may be presented by the IGS system. The virtual view may assist a surgeon in precisely positioning the distal tip at the surgical site, and then one or more flexible endoscopic tools may be advanced the length of the guide sheath for use at the surgical site. The guide sheath may also include an articulating portion at the distal tip that may be deflected in one or more directions in order to provide additional control over placement within the surgical site.

    Abstract: A rapid exchange type medical elongated body is disclosed in which an outer diameter of a distal portion of a tubular member is set smaller than an outer diameter of a proximal portion of the tubular member, which prevents an occurrence of a kink in a physical property change region of the medical elongated body which has a relatively large change in physical property. A tubular member forming a second region of a distal member of a medical elongated body is integrally formed with a shaft portion. The distal member has a reinforcement layer containing a metallic material and formed between an inner layer and an outer layer from a first region to the second region. The reinforcement layer is disposed inside the tubular member in the second region. An outer diameter of the first region is set smaller than an outer diameter of the second region.

  • Patent number: 11024525
    Abstract: A temperature shock monitor includes a solvent material and a diffusion material. An energy barrier between the solvent material and the diffusion material is selected to be lower than is would conventionally be used in semiconductor devices such that the diffusion material diffuses into the solvent material when exposed to a temperature above a designated temperature threshold. At a later time, electrical parameters of the temperature shock monitor that change based on the amount of diffusion of the diffusion material into the solvent material allows one to determine whether the temperature shock monitor was exposed to a temperature above the temperature threshold.
