摘要:
Disclosed is a treatment device for occluding a body lumen, including: an elongated body which can be inserted into the body lumen; a flat portion forming section which is supported by the elongated body, is expandable widthwise on a more distal side than the elongated body, and forms the body lumen with a flat portion at a distal portion of the flat portion forming section attendant on the expansion of the flat portion forming section within the body lumen; and a giving section which gives, toward the flat portion formed by the flat portion forming section, that which acts to occlude the flat portion.

Disclosed herein are medical devices comprising a single-lobed, thin-walled, expandable body ("ballstent" or "blockstent") and a flexible, elongated delivery device ("delivery catheter") and systems and methods of use for treating saccular vascular aneurysms and methods of use for occluding segments of blood vessels and other biological conduits. Expandable bodies comprising gold, platinum, or silver that can be compressed, positioned in the lumen of an aneurysm or blood vessel, and expanded to conform to the shape of the aneurysm or segment of blood vessel or biological conduit are disclosed.

Provided are catheters useful for penetrating the vascular wall and delivering medicament as necessary to tissue proximate the vasculature. Such catheters are particularly useful in delivering site specific medicaments to the tissue which can be damaged by hemorrhagic stroke, ischemia, and the like. Methods of using such catheters are also disclosed.

This patent application describes a rechargeable, resterilizable, portable, and easy-handling mixer (1) to create foam with microbubbles using physiological gases currently used in sclerotherapeutic treatments of varicose veins. It may be used to create foam for other therapeutic purposes by endovascular means. This reservoir has anatomical and compact dimensions and is built with material resistant to sterilization and pressure, designed to be used in treatments provided in regular medical appointments at clinical or hospital centers.
摘要:
A microcatheter comprising an elongate flexible tubular body, a tip body and a coupling is disclosed. The elongate flexible tubular body has a proximal end, a distal end and at least one lumen extending axially therethrough. The tip body has a proximal end and a distal end and a lumen extending axially therethrough. The coupling covers a portion of both the tubular body and tip body and is made from a first material and a second material, where the first material is different from the second material. The first material is compatible with an outermost layer of the tubular body and an outermost layer of the tip body, and the second material is configured to form a detachable bond with at least one of the tubular body and the tip body.
摘要:
A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.
