5 results about "Aneurysm embolization" patented technology

This invention provides an aneurysm embolization auxiliary device, belonging to the field of medical device technology. The device includes a delivery catheter, an operating handle, a balloon, and a filling unit. The delivery catheter delivers a treatment device to the aneurysm location. The operating handle is located at the proximal end of the delivery catheter. The balloon, after inflation, supports the blood vessel. The filling unit fills the aneurysm with an injectable gel for treating the aneurysm from the operating handle location along the delivery catheter. The injectable gel solidifies within the aneurysm. During operation, the delivery catheter delivers the balloon to the aneurysm location. After inflation, the balloon supports and positions the blood vessel. The filling unit fills the aneurysm with the injectable gel, which solidifies upon entering the aneurysm to treat it. This invention primarily addresses technical problems in existing interventional aneurysm treatment methods, such as easy displacement of coils and the increased risk of bleeding due to the need for long-term medication after stent implantation.

This invention provides an auxiliary stent for intracranial aneurysm embolization, belonging to the field of medical device technology. The stent includes a stent body, which extends axially and includes a first anchoring section, a support section, a second anchoring section, and a third anchoring section integrally arranged sequentially. The first anchoring section has a semi-open loop structure and forms a funnel-shaped structure. The support section has a closed loop structure and is positioned at least directly opposite the neck of the aneurysm to provide the main radial support force to resist the outward pressure of the spring coil. The second anchoring section has a semi-open loop structure and a funnel-shaped structure. The third anchoring section has an open loop structure and forms a continuous funnel-shaped structure with the second anchoring section. Through its segmented structural design, this invention significantly improves the apposition and positional stability within the blood vessel, thereby effectively reducing the risk of complications related to stent displacement and poor apposition.

An aneurysm embolization device can include a body having a single, continuous piece of material that is shape set into a plurality of distinct structural components. For example, the device can have an expandable component and an atraumatic tip portion extending therefrom. Further, the tip portion can be configured to enable the device to be implanted within the aneurysm while tending to mitigate risk of puncturing the aneurysm dome or otherwise assist in framing the aneurysm in advance of placement of additional embolic material.

The application discloses a spring ring mechanical release device and an aneurysm embolization system, relates to the technical field of aneurysm embolization devices, and comprises a push rod and a release mechanism. The distal end of the push rod is provided with a mechanical locking mechanism. The mechanical locking mechanism has a locking state and a loosening state. The mechanical locking mechanism is used for detachable connection with the proximal end of a spring ring. The distal end of the release mechanism is connected with the mechanical locking mechanism. The proximal end of the release mechanism is a force applying end. The locking state and the loosening state of the mechanical locking mechanism can be switched by controlling the force applying end. The application can realize controllability of a spring ring release time, and avoids the problems of spring ring misrelease and poor controllability.

The present invention relates to a method for preparing a filling material for cerebral aneurysm embolization, and use thereof. The filling material for cerebral aneurysm embolization, prepared according to the preparation method of the present invention, and thus can contribute to increasing the success rate of embolization and improving the safety of surgery, thereby being suitable for use in actual cerebral aneurysm embolization procedures.
