VASO-OCCLUSIVE DEVICES AND METHODS FOR MAKING AND USING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18667790 titled 'VASO-OCCLUSIVE DEVICES AND METHODS FOR MAKING AND USING SAME
Simplified Explanation: The vaso-occlusive device described in the patent application is a wire-based device that can change shape from a primary constrained configuration to a secondary relaxed configuration. The secondary configuration includes a pyramidal portion with distal coils arranged in a specific pattern.
- The wire in the device has a primary constrained configuration and a secondary relaxed configuration.
- The secondary configuration includes a pyramidal portion with distal coils wound in a specific way.
- Each distal coil is connected by a transition segment of the wire.
- The distal coils are arranged in a pyramidal shape, with each coil lying in a different lateral face of the pyramidal shape.
- The device may also include a body portion proximal to the pyramidal portion, formed from the wire.
Key Features and Innovation:
- Wire-based vaso-occlusive device
- Changeable shape from constrained to relaxed configuration
- Pyramidal portion with distal coils in a specific arrangement
- Transition segments connecting distal coils
- Body portion proximal to the pyramidal portion
Potential Applications: The vaso-occlusive device can be used in medical procedures such as embolization to block blood flow in specific vessels or areas of the body.
Problems Solved: This technology provides a more precise and controlled way to block blood flow in targeted areas, improving the effectiveness and safety of medical procedures.
Benefits:
- Enhanced precision in blocking blood flow
- Improved safety in medical procedures
- Controlled and targeted treatment
Commercial Applications: The vaso-occlusive device can be used in interventional radiology procedures, such as embolization for treating aneurysms or other vascular conditions. It has the potential to improve patient outcomes and reduce the risk of complications.
Questions about Vaso-Occlusive Devices: 1. How does the specific arrangement of distal coils in the pyramidal portion contribute to the effectiveness of the vaso-occlusive device? 2. What materials are typically used in the construction of wire-based vaso-occlusive devices?

Original Abstract Submitted
A vaso-occlusive device comprises a wire having a primary configuration in a constrained condition. The wire forms a secondary configuration in a relaxed, unconstrained condition. The secondary configuration comprises a pyramidal portion comprising a plurality of distal coils. Each distal coil is wound from the wire such that the winding has a perimeter which tapers outwardly from an interior of the pyramidal portion, and a transition segment of the wire between each distal coil and connecting each distal coil. The plurality of distal coils is arranged in a pyramidal shape such that each coil lies in a different lateral face of the pyramidal shape. The vaso-occlusive device may also include a body portion proximal of the pyramidal portion formed from the wire and extending proximally from the pyramidal portion.
