RETAINING MECHANISMS FOR PROSTHETIC VALVES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240016602 titled 'RETAINING MECHANISMS FOR PROSTHETIC VALVES

Simplified Explanation

The abstract describes a method for treating a deficient native mitral valve in a patient's heart using catheters. The method involves advancing a steerable first catheter through the patient's vasculature and positioning its distal end portion adjacent to the native mitral valve. The curvature of the distal end portion of the first catheter is adjusted to form a first curve. A second catheter with a pre-shaped distal end portion is then advanced from the first catheter, and a wire is deployed from the second catheter to extend around the native leaflets of the mitral valve.

  • The method involves using catheters to treat a deficient native mitral valve.
  • A steerable first catheter is advanced through the patient's vasculature to position it near the mitral valve.
  • The curvature of the first catheter's distal end portion is adjusted to form a curve.
  • A second catheter with a pre-shaped distal end portion is advanced from the first catheter.
  • A wire is deployed from the second catheter to extend around the native leaflets of the mitral valve.

Potential applications of this technology:

  • Treatment of patients with a deficient native mitral valve.
  • Minimally invasive alternative to open-heart surgery for mitral valve repair.

Problems solved by this technology:

  • Provides a less invasive method for treating a deficient native mitral valve.
  • Avoids the need for open-heart surgery in some cases.

Benefits of this technology:

  • Minimizes the risks and complications associated with open-heart surgery.
  • Potentially reduces the recovery time for patients.
  • Offers a less invasive option for patients who are not suitable candidates for surgery.


Original Abstract Submitted

a method of treating a deficient native mitral valve of a heart of a patient includes advancing a steerable, first catheter through the patient's vasculature, advancing the distal end portion of the first catheter into the heart to position the distal end portion of the first catheter adjacent the native mitral valve, adjusting the curvature of the distal end portion of the first catheter to form a first curve, advancing a distal end portion of a second catheter from a distal end of the first catheter, wherein the distal end portion of the second catheter is pre-shaped to form a second curve when advanced from the first catheter, and deploying a wire from the second catheter such that the wire extends around native leaflets of the native mitral valve.
