7 results about "False Aneurysms" patented technology

A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.

Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A treatment system for such treatment can include an electrolytically corrodible core wire having a proximal portion, a distal portion, and a detachment zone between the proximal portion and the distal portion. An occlusive member having a proximal hub is coupled to the core wire distal portion. A conduit extends along at least a portion of the core wire. The conduit has a lumen configured to pass an embolic element therethrough.

The invention relates to the technical field of medical instruments, and discloses a pseudoaneurysm treatment device which comprises a trocar system and an injection needle. The trocar system comprises a cannula, a puncture needle, a plugging needle and a blunt needle, and the puncture needle, the plugging needle and the blunt needle can move in the cannula; the front end of the puncture needle is a sharp head; a balloon is arranged at the front end of the plugging needle body; the front end of the blunt needle is blunt and is used for smearing thrombin; the injection needle is used for injecting thrombin into the pseudoaneurysm. The trocar system is used for achieving puncture and blocking and blood coagulation of the joint of the pseudoaneurysm and the artery, thrombin is injected into the pseudoaneurysm through the injection needle, the blood coagulation area can be limited in the pseudoaneurysm, and the reliability of pseudoaneurysm treatment is improved.

Liquid compositions comprising nimodipine having improved nimodipine concentrations are provided herein. Methods of improving neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured intracranial berry aneurysms with the liquid compositions of the present invention are also detailed herein.

A virtual angiogram can be performed by simulating transport of contrast agent through a model of a portion of a vasculature of a patient. The simulation can be based on a patient-specific pulsatile flow velocity field of the vasculature portion. At least one contrast retention metric for an aneurysm in the vasculature portion can be determined based on the virtual angiogram. The contrast retention metric can be indicative of flow stagnation in the aneurysm. In some aspects, the aneurysm can be identified as unstable based at least in part on the at least one contrast retention metric. Responsive to the identification, a treatment can be administered for the aneurysm even though it has not yet ruptured. Alternatively or additionally, the aneurysm can be identified as ruptured, for example, to discriminate between multiple potentially-ruptured aneurysms in the patient for treatment.

A method for manufacturing a tray 44 for storing aneurysm clips is disclosed, in which a metal plate 2 is first provided, which is then provided with perforations 4. The perforations 4 are produced by laser cutting, and the plate 2 provided with the perforations 4 is formed by bending into a corrugated or trapezoidal sheet 24, which has at least one trough-shaped recess 22 for storing aneurysm clips. Furthermore, a tray 44 for storing aneurysm clips is disclosed, which has a corrugated or trapezoidal sheet 24 provided with laser-cut perforations 4, wherein the corrugated or trapezoidal sheet 24 has at least one trough-shaped recess 22.
