摘要： A medical guidewire having distal tip coil that includes a twisted ribbon wire construction. The distal tip coil is mounted to the distal end of the distal core section of the guidewire. The coil is made from a flat ribbon wire with a polygonal, preferably rectangular, cross-section that is twisted along the length of the wire. The twisted, flat ribbon wire creates a tip coil that has a roughened, undulating surface at the outer circumference that, whether coated or bare, is perceptible to the physician or cardiologist when pushing or torquing the guidewire in an interventional procedure.

摘要： A guidewire, consisting of a hollow tube, containing a longitudinal lumen and having a spiral channel cut into the tube, and having a distal end. The guidewire has an elongate flexible core positioned within the longitudinal lumen. The guidewire also has a conductive coil, wound around the core at a location within the lumen in proximity to the distal end, that is coupled to output a signal in response to a magnetic field applied to the guidewire.

摘要： Improved medical filaments for use with dilators to be inserted into a patient, for example into the vascular lumen, are provided, as well as combinations of filaments and dilators. Methods for use of such filaments and filament-dilator combinations are also described. The filament includes a proximal segment and a distal segment. The diameter of the distal segment is greater than the diameter of the proximal segment. The change in diameter is abrupt, providing a discrete step transition at a point along the filament which presents a proximally-facing surface on the distal segment. When the proximal segment of the filament is fully inserted into a dilator having a distal tip adapted for insertion into a patient, the dilator distal tip firmly abuts the proximally-facing end surface of the distal segment. The relative dimensions of the dilator tip and the discrete stepped transition of the filament provides full shielding or over shielding of the dilator tip, thereby facilitating passage of the dilator tip along the tissue track, through the puncture hole and into the orifice.

摘要： Guidewires are disclosed being configured to achieve variable rigidity to facilitate percutaneous exploration and the traversal of overlying elements such as catheters, for instance in performing the Seldinger technique. Embodiments of guidewires comprise sheaths and cores configured to be tightened together to achieve stiffness of the guidewire. Embodiments further include cores having an axial passage, along with one or more sections capable of independent activation to achieve variable rigidity. Embodiments also include guidewires comprising combinations of solid, wound metallic, polymeric coils, or woven meshes, with attached or detached polymer coatings. Cores may be configured to increase or decrease pressure, pass acoustic, ultrasonic or other mechanical energy, pass one or more metallic cores to interact with the distal mechanical elements, or as a channel to pass wires to activate the distal materials in the sections and distal tip.

摘要： A guide wire includes a core shaft and a coil body covering an outer surface of a distal portion of the core shaft. The coil body includes a straight section that extends in a straight state from a proximal end of the coil body toward a distal end of the coil body, and a bent section arranged at a distal end of the straight section. The coil body may be formed by winding at least one element wire into a helical coil structure, or by winding a plurality of stranded wires (obtained by stranding a plurality of element wires) into a helical coil structure. The element wires and/or the stranded wires of the coiled body are in contact with each other on a side of the bent section opposite to a side toward which the bent section is bent relative to an axial direction of the straight section.

摘要： The present invention relates to a system and a method of measuring a physiological variable in a body. A basic idea of the present invention is to measure a physiological variable in a body by means of employing a sensor which is arranged to be disposed in the body for measuring the physiological variable. The sensor must be provided with a supply voltage in order to be operable. Therefore, a control unit disposed outside the body provides this supply voltage to the sensor. The control unit also receives, from the sensor, via a wired connection, signals that represent the physiological variables that are measured. The control unit is arranged with a communication interface and a modulator for wireless spread spectrum communication of the measured physiological variables for presentation purposes.
