Abstract: A vaso-occlusive device is disclosed. The device includes a vaso-occlusive member having a coating disposed thereon. In accordance with one embodiment, the coating comprises a polyacrylic material. In accordance with another embodiment, the coating comprises a polyvinyl alcohol-based material. In accordance with other embodiments, various other materials and coatings are applied to at least a portion of a vaso-occlusive device.

Abstract: An embodiment is a catheter comprising a first elongate shaft having a proximal end, a distal end and a first lumen therethrough, a wire having a proximal end and a distal end at least partially disposed in the first elongate shaft, the distal end extending distally from the first elongate shaft, and a motion control apparatus connected to the proximal end of the wire, further comprising a device attached to the distal end of the wire for changing the shape of an embolus, wherein the device is configured to change the shape of the embolus to unclog a distal catheter lumen.

Abstract: A medical device includes a rotational marker. A marker may be viewable under an imaging device, such as a fluoroscope or an MRI system. A rotational marker allows the rotational orientation of a medical device to be determined with respect to the surrounding environment. A medical device including a rotational marker may comprise an implantable medical device, a delivery system for delivery of an implantable medical device, and the like.

Abstract: Vaso-occlusive devices are provided for occluding an aneurysm within the human vasculature. The vaso-occlusive device also includes a stretch-resisting member that extends through at least a portion of a lumen of the primary coil and is directly or indirectly attached to the primary coil at two locations axially separated from each other to prevent or minimize axial stretching of the primary coil. At one location, the stretch-resisting member is coupled to the primary coil via a flexible anchor assembly disposed within the lumen. In one embodiment, the anchor assembly may comprise an anchor coil and a link directly or indirectly coupled between the anchor coil and the stretch-resisting member. Alternatively, the anchor assembly may comprise a chain of twisted links.

Abstract: A medical system includes an inner core and an imager located at the distal end of the inner core, wherein the imager is extendable from within an elongated tubular member and configured to penetrate a body tissue within a living body. The elongated tubular member is configured to slideably receive the inner core. The inner core is configured to rotate radially around a longitudinal axis of the elongated member, and the imager can be configured to image a body tissue and output an image signal to an imaging system communicatively coupled with the imager. The imaging system is configured to generate an image of the body tissue from the image signal of the imager when the imager is rotated and placed into contact with the body tissue.

Abstract: Disclosed herein are vaso-occlusive devices for forming occluding the vasculature of a patient. More particularly, disclosed herein are vaso-occlusive devices comprising at least one polymer structure and methods of making and using these devices.

Abstract: A device for removing blood clots and methods of making and using the same. The clot pulling device may include a first spine, a second spine disposed parallel to the first spine, and a basket disposed between and coupled to the spines. In addition, a pushing member may be coupled to the first spine and extend proximally therefrom.

Abstract: A thin film device, such as an intravascular stent, is disclosed. The device is formed of a seamless expanse of thin-film (i) formed of a sputtered nitinol shape memory alloy, defining, in an austenitic state, an open, interior volume, having a thickness between 0 5-50 microns, having an austenite finish temperature Af below 37° C.; and demonstrating a stress/strain recovery greater than 3% at 37° C. The expanse can be deformed into a substantially compacted configuration in a martensitic state, and assumes, in its austenitic state, a shape defining such open, interior volume. Also disclosed is a sputtering method for forming the device.

Abstract: Methods and devices provide for temporary partial aortic occlusion to achieve diversion of blood flow to the brain in patients suffering from cerebral ischemia. The device can include an expandable frame with a membrane mounted on a first portion of the frame. The membrane can have at least one opening. In some embodiments, the membrane has an outer region and an inner region, and an opening in the inner region. In use, the frame can expand to conform to the inner walls of the aorta and the membrane can at least partially occlude the aorta thereby increasing cerebral perfusion. The frame can include one or more anchors to aid in maintaining the device in position against the arterial blood flow pressure.

Abstract: Methods and devices for blocking orifices and occluding cavities within a patient are provided. The device in one variation comprises first and second tubular members attached to a collapsible sealing element. The device can be placed through an orifice and the collapsible sealing element can be collapsed to seal the orifice. An embolic may be introduced distal to the sealing element to occlude a cavity. The device may incorporate a locking mechanism which can be engaged to lock the sealing element into the collapsed position. The device may incorporate a valve to prevent flow through the tubular members, for example to prevent egress of the embolic from a cavity. The device can be detached to provide a permanent seal of the orifice, and can retain the embolic within the cavity. The device may be used in conjunction with a stent or other retention device to assist the sealing element in maintaining the seal.

Abstract: A composition including 2-hexyl cyanoacrylate and gold is useful in treating arteriovenous malformations (AVMs) and other body lumens to be blocked.
