Innovative Flow Blocking Electrode for Vascular Care

Introduction

This flow blocking electrode technology is designed to provide precise control over blood flow during vascular and interventional procedures, offering medical professionals a safer and more effective tool for managing blood flow in critical interventions. The electrode is engineered to temporarily block flow in a specific region, allowing for enhanced precision and reducing risks during procedures such as catheter insertions, stent placements, and vascular surgeries. For companies in the medical device and healthcare industries, this technology provides an innovative solution to improve patient outcomes and enhance procedural safety.

The Challenge: Managing Blood Flow in Critical Interventions

Controlling blood flow during vascular and interventional procedures is critical for minimizing complications, preventing blood loss, and ensuring accurate device placements. However, traditional methods for blocking or managing blood flow during these procedures can be invasive, time-consuming, and prone to risks such as clot formation or vessel damage. Physicians and surgeons need more reliable tools that allow them to temporarily and effectively block blood flow in specific areas, giving them greater control over the procedure while reducing the risk of complications.

Flow Blocking Electrode for Precise Vascular Control

This flow blocking electrode technology addresses these challenges by providing a highly effective and minimally invasive method for controlling blood flow in a specific area during medical procedures. The electrode works by generating an electrical signal that temporarily blocks flow in targeted blood vessels, giving medical professionals the control they need to perform delicate interventions safely and efficiently. This device offers improved precision, reducing the likelihood of complications such as excessive bleeding or unintended vessel damage. Additionally, the electrode’s design makes it easy to integrate into existing vascular tools and devices, streamlining the overall procedure.

Key Benefits for Medical Device Manufacturers and Healthcare Providers

For medical device manufacturers, this flow blocking electrode represents a significant advancement in vascular care, offering a new tool that enhances safety and effectiveness in critical procedures. Healthcare providers, including vascular surgeons and interventional cardiologists, can benefit from the electrode’s ability to improve procedural control, reduce complications, and shorten recovery times for patients. This technology also offers potential applications in diagnostics, where precise control of blood flow can improve imaging and treatment accuracy.

Abstract
Claims

An electrosurgical wand is disclosed. The electrosurgical wand includes a handle that defines a proximal end of the electrosurgical wand. The electrosurgical wand includes an elongate shaft coupled to the handle; the elongate shaft defines a suction lumen therein. The electrosurgical wand also includes an electrically insulative spacer (404) coupled to the distal end of the elongate shaft, whereby the spacer defines a suction channel (412) fluidly coupled to the suction lumen. The electrosurgical wand includes a first means for blocking defined by the spacer, an active electrode (402) coupled on the distal end of the spacer and a second means for blocking associated with the active electrode and in operational relationship to the first means for blocking. In the electrosurgical wand, the first means for blocking includes an annular trough (416) that fully encircles the suction channel of the spacer and the second means for blocking includes an annular wall (414).

What is claimed is:

1. An electrosurgical wand comprising:

a handle that defines a proximal end of the electrosurgical wand;

an elongate shaft coupled to the handle, the elongate shaft defines a suction lumen therein;

a spacer coupled on a distal end of the elongate shaft, and the spacer is electrically insulative;

a distal surface defined by the spacer, the distal surface is flat and defines an outer edge of the spacer;

a suction channel through the spacer and fluidly coupled to the suction lumen, the suction channel defines an aperture at the distal surface;

an annular trough defined in the spacer, the annular trough comprises a closed bottom and an open top, the open top intersects the distal surface that is flat, and the annular trough fully encircles the suction channel;

an active electrode coupled to the distal surface of the spacer, wherein an outer edge of the active electrode aligns with the outer edge of the spacer; and

an annular wall that extends from the active electrode into the annular trough, and the annular wall encircles the suction channel of the spacer.

2. The electrosurgical wand of claim 1, wherein the annular wall fully encircles the suction channel of the spacer.

3. The electrosurgical wand of claim 1 further comprising an adhesive in the annular trough.

4. The electrosurgical wand of claim 1, wherein a height of the annular wall is nonzero and less than or equal to half of a width of the active electrode.

5. The electrosurgical wand of claim 1 further comprising no adhesive in the annular trough.

6. The electrosurgical wand of claim 1 wherein the outer edge of the active electrode is set back from the outer edge of the spacer by between 1 and 15 thousandths of an inch.

7. The electrosurgical wand of claim 1 wherein the outer edge of the active electrode does not overhang the outer edge of the spacer.

8. The electrosurgical wand of claim 1 wherein the active electrode further comprises an aperture aligned with the suction channel of the spacer.
