An embolic protection system for delivering, deploying, and retrieving a filter configured to capture particles that may become dislodged during a medical procedure. The embolic protection system may include an embolic protection device that captures the particles, a delivery catheter assembly for delivering the embolic protection device to a target location within the vasculature, and a retrieval catheter assembly for retrieving the embolic protection device, along with the captured particles, from the target location after use. The embolic protection device includes a filter movably connected to a guidewire, such that after deployment, the filter can move both axially and rotationally relative to the guidewire, thereby reducing the risk of vasospasm or vascular dissection.

The present invention provides a vasospasm inhibitor and an oral composition for inhibiting vasospasm that can suppress abnormal vasoconstriction (vasospasm). [Solution] A vasospasm inhibitor and an oral composition for inhibiting vasospasm, containing as an active ingredient at least one compound selected from the group consisting of 2,5-dihydroxybenzoic acid, trans-3-caffeoylquinic acid, trans-4-caffeoylquinic acid, trans-5-caffeoylquinic acid, and 2-hydroxybenzoic acid, or a salt thereof.

The utility model discloses a kind of venous hot compress sleeve, including the rectangular block of the sleeve main body made of skin-friendly material, sleeve main body is equipped with heating area, the left side of sleeve main body is equipped with first connecting belt, the right side of sleeve main body is equipped with second connecting belt, corresponding position of first connecting belt and second connecting belt is equipped with detachable connecting piece respectively, the position of first connecting belt close to sleeve main body is equipped with infusion leather strip connecting piece, the position of second connecting belt close to sleeve main body is equipped with elastic tightness area.The utility model can realize temperature controllable and heat preservation to a certain extent, improve hot compress operation convenience and security, not only can help patient expand venous vessel, promote drug absorption, also can relieve pain caused by vasospasm, reduce swelling or induration.

The utility model discloses a medical baking lamp capable of shading, which comprises a support, a lampshade assembly, a shading assembly and a baking lamp assembly, the shading assembly is composed of a mounting ring and shading cloth, the mounting ring is composed of an upper circular ring and a lower circular ring, the shading cloth is sleeved on the lower circular ring, and meanwhile, the upper circular ring is mounted on the side part of a sealing plate; the shading assembly of the device is provided with shading cloth, the shading cloth shields light of the whole bulb, light scattering of the lamp is avoided, sleep and mood of a patient and a patient in the same room are prevented from being affected, meanwhile, a zipper can be unzipped, an opening of the shading cloth can be pushed aside, light can be concentrated on the patient, the treatment efficiency can be improved, and the device is very convenient to use; the height of the telescopic rod can be adjusted, different use scenes are met, meanwhile, the distance between the bulb and a patient can be controlled through the folding rod, and the situations that vasospasm is caused and nerves which are not recovered yet are burnt are avoided.

The invention discloses a cerebral vasospasm cell image recognition method and system, relates to the technical field of image recognition, and is used for solving the problem that in cerebral vasospasm cell image recognition, image quality reduction, cell morphology change and pathological feature confusion are caused by blood pollution, and consequently a traditional recognition method fails. The method comprises the following steps: acquiring an original cerebral vasospasm cell image, and converting the original cerebral vasospasm cell image into a basic information flow image; fourier transform is carried out on a local area in the basic information flow image to generate a phase enhancement image; performing color space conversion on the basic information flow image to generate color and texture features; performing morphological operation and connected domain analysis on the basic information flow image to generate morphological topological features; and obtaining edge texture features of the phase enhancement image, performing comprehensive judgment according to a preset rule in combination with the color and texture features and the morphological topological features, and outputting a cerebral vasospasm cell recognition judgment result.

Microcatheters having enlarged distal ends with distally decreasing tapered portions are disclosed. These microcatheters can be used for various treatments within a vessel, such as treatment of a vasospasm and delivery of a liquid embolic material.
