The Drivewire 24 Guidewire is intended for general intravascular use, including the neuro and peripheral vasculature. The Drivewire 24 Guidewire is intended to facilitate the selective placement of diagnostic catheters. This device is not intended for use in the coronary arteries.

The Drivewire 24 Guidewire is a 0.024" diameter steerable guidewire with a deflectable tip to aid in accessing vasculature. The guidewire is supplied sterile (ETO sterilization) and is for single use only. The Drivewire 24 Guidewire is comprised of a stainless steel hypotube that is cut along its length to provide flexibility and tip deflection ability through control of the handle, an inner Nitinol braided flexible coil, an inner core wire, and a handle. The inner core wire runs inside the hypotube from the distal end to the handle. The distal end of the inner core wire is flattened, looped around and joined to the tip of the distal section of the hypotube, forming a deflectable tip. The hypotube is marked with fluoro-safe markers to provide visual clues to the user to initiate fluoroscopy guided insertion. In order to actuate the tip deflection in two directions, the Drivewire 24 Guidewire handle contains a tube assembly section. The handle is assembled to the proximal end of the core wire and controls the movement of the distal tip by pulling/pushing the inner moveable core wire, allowing the bending of the distal tip in two directions. The handle assembly has neutral landmarks to identify the location where the tip is straight. The Drivewire 24 Guidewire has a hydrophilic coating on its distal segment in order to reduce the friction of the guidewire while navigating. The Drivewire 24 Guidewire is provided with a torque accessory to facilitate use of the guidewire and is not intended to have patient contact.

The Columbus Guidewire is intended for general intravascular use, including the neuro and peripheral vasculature. The Columbus Guidewire is intended to facilitate the selective placement of therapeutic catheters. This device is not intended for use in coronary arteries.

The Columbus guidewire is a 0.014" diameter steerable guidewire with a deflectable tip to aid in accessing vasculature. The guidewire is supplied sterile (ETO sterilization) and is for single use only. The Columbus guide wire is comprised of a Nitinol braided flexible distal cable, a proximal shaft, an inner core wire and a handle. The braided cable is attached to the proximal shaft via inner connector. The inner core wire runs inside the shaft and the cable from the distal end of the cable to the handle. The distal end of the inner core wire is flattened, looped around and joined to the tip of the distal cable, forming a deflectable tip. In order to actuate the tip deflection in two directions, the Columbus guidewire handle contains a tube assembly section which enables continuous stroke by a self-locking feature. The handle is assembled to the proximal end of the core wire and controls the movement of the distal tip by pulling/pushing the inner moveable core wire, allowing the bending of the distal tip in two directions. Two models are available, Columbus LR (large radius) PN: GWPP4464 which has radius curvature of 4mm and Columbus SR (small radius) PN: GWPP4463 which has radius curvature of 2mm. The Columbus guidewire is provided with a torque accessory to facilitate use of the guidewire and is not intended to contact the patient's body.

The Comaneci Embolization Assist Device is indicated for use in the neurovasculature as a temporary endovascular device used to assist in the coil embolization of wide-necked intracranial aneurysms with a neck width ≤ 10 mm. A wide-necked intracranial aneurysm defines the neck width as ≥ 4 mm or a dome-to-neck ratio < 2.

The Comaneci Embolization Assist Device consists of three device models: Comaneci, Comaneci Petit, and Comaneci 17 (see Table 1). The Comaneci Embolization Assist Device is intended for temporary use and is introduced through an endovascular approach to the neurovasculature to assist in the coil embolization of wide-necked intracranial aneurysms with a neck width < 10 mm. The device consists of a nitinol fine wire mesh region at the distal end mounted on a flexible shaft that expands and contracts when the physician pulls a core wire that is coated with polytetrafluoroethylene (PTFE) and connected to a handle with a control slider made of a styrene-butadiene copolymer (Figures 1 and 2). The fine wire mesh region on the Comaneci Embolization Assist Device is unique in that it is not self-expandable but is directly controlled by the physician to size this region of the device to the parent vessel. The wires of the mesh are radiopaque, which allows the physician to visualize the mesh under fluoroscopy. The Comaneci and Comaneci Petit models are delivered through a microcatheter with an internal diameter (ID) of 0.021 inches and the Comaneci 17 is delivered through a microcatheter with an ID of 0.017 inches. The devices are packaged in a sterile pouch and are intended for single use only.
