Abstract: A system for moving an elongate medical device has at least one drive element for engaging and moving an elongate medical device. Various embodiments provide for moving the separate inner and outer elements of a telescoping medical device. Some systems also provide for the rotation of a rotatable distal element on a rotatable medical device or the rotation of extension element in a telescoping medical device.

Abstract: Embodiments of the invention include an aneurysm filler, comprising a main body having a transport shape and three-dimensional shape which is manifest when the main body is deployed in an aneurysm.

Abstract: Inventive subject matter described herein includes an induction coil resistance tester, comprising: a base effective for absorbing vibration; a mechanism for moving a sample in x, y, and z directions; a scale for measuring weight of the sample; and an ohmmeter for measuring resistance of the sample.

Abstract: Embodiments of the invention include a catheter, comprising: a lumen having a distal end and a proximal end; one or more marker bands circumferentially arranged around the lumen; a support structure extending from the proximal end of the lumen to the most distal marker band; and a top jacket positioned annularly with respect to the lumen, comprising five durometers of material, wherein the support structure and top jacket alternate along the length of the catheter.

Abstract: An advancer system is described for moving an elongate medical device within a body. The system includes a drive unit having a motor. The drive unit is configured to translate movement of the motor to the device so as to alternately advance and retract the device relative to the body. The advancer system also includes a user-operable control system configured to control the drive unit. The control system can interface with a magnetic navigation system. The above-described system allows an operating physician to control catheter advancement and retraction while remaining outside an x-ray imaging field. Thus the physician is freed from repeated x-ray exposure.

Abstract: A method of navigating the distal end of a medical device through an operating region in a subject's body includes displaying an x-ray image of the operating region, including the distal end of the medical device; determining the location of the distal end of the medical device in a reference frame translatable to the displayed x-ray image; and displaying an enhanced indication of the distal end of the medical device on the x-ray image to facilitate the navigation of the distal end of the device in the operating region.

Abstract: A magnetically navigable medical guidewire, comprising an elongate wire having a proximal end, and a distal end; a hollow cylinder secured on the distal end of the wire forming the tip of the guidewire. A magnetically responsive element is disposed inside said hollow cylinder. The distal tip has a rounded, dome-shaped configuration.

Abstract: A design and method of manufacture is disclosed for an insulated electrode used during surgical procedures. The electrode includes a durable electrical insulation element that can withstand the range of temperatures generated during an electrosurgical procedure. Such insulation characteristics include resistance to meltback and manufacturability to ensure the device is biocompatible and non-toxic so as to prevent adverse reactions in both patients and users of the device. The insulated electrode further includes properties that reduce the incidence of scope damage caused by the intensity of heat generated during the cutting and coagulation cycles.
