Puncture Catheter

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a puncture catheter designed for safely puncturing tubular structures such as blood vessels or ducts. It features at least two parallel channels (lumina) and an inflatable balloon at the tip, which can be expanded via one channel to fix the catheter securely in place and allow precise, sealed puncture of the structure using the second channel.

Use CasesContent extracted from patent full text and abstract with AI.

• Performing targeted drug delivery or interventions inside blood vessels, airways, esophagus, or other tubular organs
• Setting implants (e.g., clips, coils, radioactive seeds, or markers) with high precision inside tubular structures
• Removing fluids or thrombi (blood clots) from vessels or ducts
• Taking tissue samples (biopsies) from areas beyond tubular structures
• Providing safe vessel or duct closure after interventions (hemostasis)

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces the risk of accidental misplacement or leakage during puncture due to secure fixation with the inflatable balloon
• Enables highly targeted, lateral puncture of tubular structures, which is not possible with conventional catheters
• Allows for effective sealing of the puncture site, minimizing blood or fluid loss
• Facilitates a wide range of therapeutic and diagnostic procedures in various tubular organs
• Simplifies positioning through the use of imaging-visible markers and compatible connectors for guided interventions

Patent Abstract

The invention relates to a catheter (20) for puncturing tubular structures (9), comprising at least two lumina (1, 2) extending parallel to each other at least in sections, a balloon (3) which can be inflated by a first lumen (1) is arranged on a distal end of the lumina (1, 2).
