摘要:
A method for administering a liquid medical substance in a vein. The method comprises inserting a plurality of tubular ducts into a target venous lumen, conducting a liquid medical substance via at least one of the plurality of tubular ducts (106, 215, 419, 602) for the administering thereof toward a venous wall (110, 410) at the target venous lumen in an ejection pressure, quantity and direction, and withdrawing a residue of the liquid medical substance from the target venous lumen, in a suction pressure, quantity and direction, for the conducting thereof via at least one different of the plurality of tubular ducts (130, 240, 400). A relation between the ejection pressure, quantity and direction and the suction pressure, quantity and direction limits the extent of the administering within the venous lumen to a predefined space.

There is provided herein a system, device and methods for performing minimally invasive spider vein treatments. In some embodiments an apparatus for eliminating spider veins comprises a dual syringe mechanism that includes a pusher for pushing sclerosant materials into a target vein, and an extractor for extracting debris from a target vein; a needle for application into a target vein; and a Y-connector connecting each exit of the dual syringe mechanism to the needle. In some implementations the apparatus's dual syringe mechanism includes a locking mechanism to enable controlled advancing of the syringe pusher.

A medical implant for occluding a blood vessel. The medical implant comprises a cup shaped elastic blood impermeable membrane sized and shaped for substantially occluding a lumen of a blood vessel, at least one scaffolding element mounted, sized and shaped for being attached at least one blood clot forming in front of the elastic blood impermeable membrane, and at least one anchoring element having a tip directed outward from the center of the cup shaped elastic blood impermeable membrane.

A caulking gun having a push rod-formed by two interlocking chains. The caulking gun comprises a barrel having an open framework for receiving and cradling a caulk cartridge. A self-contained drive mechanism is provided to forwardly advance a chain arrangement comprising two separately coiled chains, each composed of a series of individual links connected in pivotable fashion one to another. The shape of the individual links of the two chains enables them to be interlocked as one parallel chain, forming a push-rod to compress the caulk cartridge, for extrusion of material contained therein. The coiled chains enable the chain arrangement to bend 180 degrees, so that the overall caulking gun length is reduced. The caulking gun is preferably made entirely from plastic. A caulk cartridge is retained within the barrel of the device by a pair of locking clips which may be closed by a sliding ring mechanism.
摘要:
A coupling device, set to be linked to an interventional delivery system, for coupling and releasing a medical implant. The coupling device comprises a generally tubular channel sized and shaped to be conducted in an intravascular catheter and a pivot extended in and along the generally tubular channel having a distal end comprising a lower surface for applying pushing force a medical implant and an upper surface, mounted above the lower generally tubular surface and having at least one niche for receiving at least one anchoring element of the medical element so that a tip of each the anchoring element is placed between the lower and upper surfaces.
摘要:
A tool holder unit for attachment to a user's belt comprising an ergonomically-shaped base; an ergonomically-shaped front section attached at its top end to the ergonomically-shaped base, the ergonomically-shaped front section having means for insertion of at least one of a tool and tool accessories; and means for securing a user's belt between the ergonomically-shaped base and the ergonomically-shaped front section, such that the tool holder unit does not become displaced from the user's belt due to body motion by the user.

摘要:
An aortic protection device including a mesh lumen shaped and sized to extend along the aorta, from a heart-side of a brachiocephalic artery exit from the aorta to distal of a left subclavian artery exit from the aorta, wherein the mesh lumen is arranged to change a porosity of mesh pores in response to external control. Related apparatus and methods are also described.
摘要:
A device and method for treating bodily diseases and/or conditions, for example, varicose veins, tumors and aneutisms including for example insertion of a blocking device toward a target destination using a catheter and delivery of sclerosing or other agents to the vessel while maintaining minimal, for example zero pressure in the treatment area, The blocking device may prevent treatment materials, embolisms, debris etc., from entering the upstream section of vessel. The blocking device may include, for example, a cap or other concave shape and may be expandable or extendible towards the vessel walls.
