MEDICAL INTRODUCER SHEATH WITH MEASURE AGAINST AIR INTRUSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024636 titled 'MEDICAL INTRODUCER SHEATH WITH MEASURE AGAINST AIR INTRUSION

Simplified Explanation

The patent application describes a medical introducer sheath that includes an inner sheath and an outer sheath. The inner sheath has a main lumen in fluid communication with a side port, while the outer sheath covers the inner sheath and defines one or more sub-lumens. The outer sheath is in gas-tightly contact with or formed in a unitary body with the inner sheath.

  • The medical introducer sheath has a steerable distal end portion and a proximal end portion fixed with a hub having a side port.
  • The inner sheath is elongated from the distal end portion to the proximal end portion and is opened on both ends.
  • The inner sheath defines a main lumen that is in fluid communication with the side port.
  • The outer sheath runs along the outer face of the inner sheath and defines one or more sub-lumens.
  • Each sub-lumen is elongated from the distal end portion and terminates at any position anterior to a proximal end of the inner sheath.
  • The outer sheath covers the inner sheath throughout its length and is in gas-tightly contact with or formed in a unitary body with the inner sheath at least at the proximal end portion.

Potential Applications:

  • Minimally invasive medical procedures requiring access to blood vessels or other body cavities.
  • Catheterization procedures.
  • Endoscopic surgeries.
  • Interventional radiology procedures.

Problems Solved:

  • Provides a sheath with a steerable distal end portion for easier navigation through the body.
  • Allows for multiple sub-lumens for the introduction of various medical devices or fluids.
  • Ensures gas-tight contact between the inner and outer sheaths for improved performance and safety.

Benefits:

  • Improved maneuverability and control during medical procedures.
  • Enhanced versatility with multiple sub-lumens for various applications.
  • Reduced risk of gas leakage during procedures.
  • Simplified design for ease of use and manufacturing.


Original Abstract Submitted

a medical introducer sheath having a steerable distal end portion and a proximal end portion fixed with a hub having a side port is provided with: an inner sheath elongated from the distal end portion to the proximal end portion and opened on the distal end portion and the proximal end portion, the inner sheath defining a main lumen in fluid communication with the side port; and an outer sheath running along an outer face of the inner sheath and defining one or more sub-lumens, each sub-lumen being elongated from the distal end portion and terminating at any position anterior to a proximal end of the inner sheath, the outer sheath covering the inner sheath throughout from the distal end portion to the proximal end portion and, at least at the proximal end portion, being in gas-tightly contact with or being formed in a unitary body with the inner sheath.
