CATHETER WITH DEFORMABLE DISTAL ELECTRODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240016541 titled 'CATHETER WITH DEFORMABLE DISTAL ELECTRODE

Simplified Explanation

The abstract describes a catheter probe with a deformable electrode that can provide a larger tissue contact area without increasing the size of the catheter. The electrode is made of a hollow porous tube with a closed distal end and an opening at the proximal portion. The distal tip end is received in the tube through the opening, and the proximal portion is affixed to the outer surface of the distal section. The closed distal end is shaped with a bulbous portion that can spread and widen to increase the surface contact area.

  • The catheter probe has a deformable electrode that can adopt a neutral configuration and a tissue contact configuration.
  • The electrode is made of a hollow porous tube with a closed distal end and an opening at the proximal portion.
  • The distal tip end is received in the tube through the opening, and the proximal portion is affixed to the outer surface of the distal section.
  • The closed distal end is shaped with a bulbous portion that can spread and widen to provide a larger surface contact area.

Potential Applications:

  • Medical procedures requiring catheter probes for tissue contact, such as ablation or biopsy.
  • Treatment of larger and deeper lesions or tumors without increasing the size of the catheter.

Problems Solved:

  • Limited tissue contact area of traditional catheter probes for larger or deeper lesions.
  • Need for larger catheter size to accommodate a larger tissue contact area.

Benefits:

  • Increased tissue contact area without increasing the size of the catheter.
  • Improved ability to treat larger and deeper lesions or tumors.
  • Potentially reduces the invasiveness of medical procedures.


Original Abstract Submitted

a catheter probe configured with a capability to present a larger tissue contact area or “footprint” for larger, deeper lesions, without increasing the french size of the catheter, especially its distal section, includes an elastically deformable electrode configured to adopt a neutral configuration and a tissue contact configuration. the deformable electrode comprising a hollow porous tube with a distal portion having a closed distal end, and a proximal portion defining an opening to an interior of the tube, where the distal tip end is received in the tube through the opening and the distal section is generally surrounded by tube, with the proximal portion being affixed to an outer surface of the distal section. in some embodiments, the closed distal end is shaped with a bulbous portion that can spread and widen to provide a larger surface contact area.
