摘要： A catheter device that is useable to penetrate from a blood vessel in which the catheter device is positioned to a target location comprises a flexible catheter advanceable into the first blood vessel, a tissue penetrator lumen adapted to receive an operative tissue penetrator which is usable to penetrate from the blood vessel to the target location when properly aimed. Further said catheter including an imaging transducer fixedly mounted on or within the catheter body to provide an imaging signal from which an image of the target location can be obtained. The catheter device may include an imageable marker on the catheter to form on the image obtainable from the imaging signal a penetrator path indication that indicates the path that will be followed by the tissue penetrator when the tissue penetrator exits from the catheter. Alternatively, or addition thereto, the imaging transducer may comprise a plurality of imaging elements which are located so that the penetrator path indication can be obtained. A method of utilizing such a catheter device to bypass an arterial obstruction is also disclosed.

摘要： Devices and methods for visually confirming the positioning of a distal end portion of an illuminating device placed within a patient include inserting a distal end portion of an illuminating device internally into a patient, emitting light from the distal end portion of the illuminating device, observing transillumination resulting from the light emitted from the distal end portion of the illuminating device that occurs on an external surface of the patient, and correlating the location of the observed transillumination on the external surface of the patient with an internal location of the patient that underlies the location of observed transillumination, to confirm positioning of the distal end portion of the illuminating device.

摘要： Devices, systems and methods useable for dilating the ostia of paranasal sinuses and/or other passageways within the ear, nose or throat. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, an optional handle may be used to facilitate grasping or supporting a device of the present invention as well as another device (e.g., an endoscope) with a single hand.

摘要： A method for dilating a stenotic region in an airway of a patient may include advancing a balloon catheter through the airway of the patient to position an inflatable balloon of the catheter within at least a portion of the stenotic region, maintaining a position of the catheter relative to the patient, and inflating the balloon of the catheter to dilate the stenotic region of the airway. A system for dilating a stenotic region in an airway of a patient may include a catheter shaft having an overall length of less than 70 cm, an inflatable balloon disposed along a distal portion of the catheter shaft, and a stylet.

摘要： A dilation catheter device and system for dilating an opening in a paranasal sinus and/or other passageways within the ear, nose or throat is disclosed. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, shaft markers are disposed on a shaft of the dilation catheter and have a light color to contrast with a dark color of the dilation catheter shaft. The high contrast between the markers and catheter shaft allows for easy viewing of the markers in low light and operation conditions.
