Abstract:
An embolectomy cage having an elongate axis and a circumference comprises a plurality of paired, closely spaced, substantially parallel, elongate members collectively defining a plurality of open cells, wherein individual elongate members of the pairs are connected at nodes located between respective pairs of axially adjacent cells and circumferentially adjacent cells, and wherein at least one elongate member spans each node without forming a connection to another elongate member.
Abstract:
A solid embolic material that is capable of filling irregularly shaped and asymmetrical vascular defects in a controlled and predictable manner, without the difficulties associated with delivery of the embolic material through a microcatheter and containment of the embolic material in a defect. A detachable embolic balloon with optional check valve for maintaining liquid in the balloon prior to curing and optional multi-leaflet covering to prevent the balloon from expanding into the native vascular lumen.
Abstract:
Occlusion-removing devices (10) that include an inflatable balloon (15) for arresting blood flow and a occlusion-shearing element (14) are provided. The device includes a housing element (11) with lumens and an embolism collector (12) and cutting element (14). Also provided are methods for making and using these devices.
Abstract:
A stent delivery system (100) comprises a stent having a first connector (126) disposed on a stent proximal end, and a pusher wire (106) having a second connector (128) disposed on a pusher wire distal end, wherein the first and second connectors are configured to releasably attach to each other.
Abstract:
Vaso-occlusive devices (50(1)) for occlusion of a body cavity are provided. The vaso-occlusive devices (50(1)) include an elongate vaso-occlusive member (12) having one or more key-ways (54a, 54b) and one or more fold lines (15c). Methods of using the vaso-occlusive devices are also described.
Abstract:
This is a device for occluding a space within the body. In particular, the device comprises a plurality of strands (10) comprising a porous, non-biodegradable material having a pore size of less than about 20 microns, and a vaso-occlusive inner member, wherein the non-biodegradable material is attached to the inner member at one or more locations.
