  "title": "A Medical Guidewire That Bends to Protect Tissue",
  "original_title": "Medical guidewire assembly having predetermined spatial geometry",
  "summary": "This patent describes a medical guidewire assembly designed to safely puncture a body wall, featuring a flexible tip that automatically forms a protective shape once it exits a guiding tube, preventing the sharp piercing tool from accidentally harming nearby healthy tissue.",
  "what_it_does": "This medical guidewire assembly helps doctors safely puncture a biological wall inside a patient's body. It uses a 'guidewire introducer,' which is like a guiding tube, placed near the wall. The assembly has a 'flexible distal shaft section' (the tip) that extends through this tube. Once this flexible tip leaves the introducer, it automatically takes on a 'predetermined spatial geometry' (a specific, pre-set shape). This shape is designed to keep the 'piercing stylet device' (a sharp tool within the guidewire) from touching any healthy tissue nearby after it punctures the wall. For example, if a doctor needs to puncture a blood vessel wall, this guidewire would ensure the sharp tip is immediately shielded by the guidewire's bent shape once it's through, protecting surrounding organs.",
  "what_it_does_not_cover": [
    "Does not cover guidewires that do not form a specific, predetermined shape after exiting the introducer.",
    "Does not cover guidewires where the formed shape fails to prevent contact between the piercing stylet and adjacent tissue.",
    "Does not cover guidewire assemblies that do not include a separate piercing stylet device for puncturing.",
    "Does not cover guidewires where the flexible distal shaft section does not move through a guidewire introducer.",
    "Does not cover guidewires used for purposes other than puncturing a biological wall within a patient's body."

  "abstract": "Medical guidewire assembly is movable through guidewire introducer positionable proximate to a biological wall located within the body of a patient. Medical guidewire assembly has flexible distal shaft section configured to extend along the guidewire introducer. Medical guidewire assembly has a predetermined spatial geometry once the flexible distal shaft section is removed from guidewire introducer. Medical guidewire assembly also has a piercing stylet device configured to puncture the biological wall in response to placement of guidewire introducer (in use) proximate to the biological wall, and movement of the flexible distal shaft section through the guidewire introducer. The predetermined spatial geometry is configured to prevent physical contact between the piercing stylet device and adjacently positioned tissue of the patient in response to formation of the predetermined spatial geometry.",
