    摘要: The apparatus for deployment of a therapeutic device such as a micro-coil detachably mounts the therapeutic device to a distal portion of a pusher member. In one embodiment, the therapeutic device is detachably mounted to the distal portion of the pusher member by a tubular collar that can be heated by a heater such as an electrical resistance coil to expand the collar and release and deploy the therapeutic device. The apparatus for deployment of a therapeutic device such as a micro-coil may also provide for a pusher member and a connector fiber for securing the therapeutic device to the pusher member. The connector fiber passes through a heater within the distal portion of the pusher member, for heating and breaking the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.

    摘要: Detection and characterization of laser-induced heat affected zones on polymer based devices, such as polymeric stents, are described where Nano Thermal Analysis may be used with atomic force microscopy to obtain the thermal behavior of materials with a spatial resolution of under, e.g., 100 nm. Heat may be applied locally to the measured polymeric stem via a probe tip and the resulting thermal-mechanical response can be measured.

    摘要: A medical system is a medical device, such as a catheter, that includes an inner core and an imager that is extendable from within an elongated tubular member and configured to penetrate a body tissue within a living body. The elongated tubular member has a distal end and is configured to slideably receive the inner core. The distal end is further configured to allow the inner core to advance outside the elongated member. The inner core has a distal end and is configured to rotate radially around a longitudinal axis of the elongated member. The device can further include an imager located at the distal end of the inner core, 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 such that the imager penetrates the body tissue.

    摘要: An assembly for occluding a vascular site (e.g., an aneurysm) of a human or veterinary patient includes a vaso-occlusive member, a pusher member having a distal end and a severable junction located proximal to the distal end, and a pivotable coupling that couples the pusher member to the occlusive member. A delivery catheter can be used to deliver the vaso-occlusive member to the vascular site. A method of using the assembly to occlude an aneurysm having an aneurysmal sac and an aneurysmal neck, includes locating the catheter within the aneurysmal neck, and manipulating the pusher member to place the vaso-occlusive member within the aneurysmal sac. The method further includes severing the severable junction to detach the vaso-occlusive member from the pusher member. As a result, an axial force is applied by the vaso-occlusive member in a proximal direction, which buckles the pivotable coupling to laterally deflect the axial force. The lateral deflection of the axial force caused by the buckling of the pivotable coupling prevents the catheter from being displaced from the aneurysmal neck by the axial force.
