摘要： A balloon catheter includes an elongate shaft, a balloon, and one or more biasing members. The elongate shaft has a proximal end and a distal end. The balloon is attached to the elongate shaft at the distal end of the elongate shaft. The balloon includes a balloon chamber for receiving inflation fluid. The one or more biasing members are connected to the balloon. The one or more biasing members move to a non-biased state when the balloon is inflated and move to a biased state when the balloon is deflated such that the one or more biasing members cause the balloon to return to an original shape of the balloon.

摘要： A catheter insertable into a patient for monitoring pressure having an expandable outer balloon. An expandable inner balloon is positioned within the lumen of the catheter and has having a second outer wall and forms a gas chamber to monitor pressure within the patient. In response to pressure exerted on the outer wall of the outer balloon, fluid within the outer balloon enters an opening in the wall of the catheter lumen to exert a pressure on the outer wall of the expanded inner balloon to deform the inner balloon and compress the gas within the inner balloon. A pressure sensor communicates with the gas containing chamber for measuring pressure based on compression of gas caused by deformation of the expanded inner balloon resulting from deformation of the expanded outer balloon.

摘要： A comprehensive multi-functional device platform that can be variably configured by clinician operators for patient-specific anatomies and clinical situations for treating complex and total occlusions is provided. This device platform enables physicians of any skill level to effectively treat the most challenging and complex lesions/occlusions more conveniently in less time. The Functionally Integratable Catheter System (“FICS System”) represents a system of “functional units” that can be configured together to operate synergistically, and comprises at least five main “functional units,” including: (a) FICS Support Catheter; (b) FICS Dilator; (c) FICS PTA Catheter; (d) FICS Lock-Grip Handle; and (e) FICS Steering Hub. Each “functional unit” can be provided in a pre-assembled form by the manufacturer, intended to be configured into variable combinations by clinician operators.

摘要： A system for assessing an intervertebral disc space comprises an elongated catheter with proximal and distal ends and an expandable body carried at the distal end of the elongated catheter. The expandable body includes a distal cap portion. The system further includes a mandrel extending through the elongated catheter and the expandable body and attached to the distal cap portion. The mandrel is movable within the elongated catheter and the expandable body to reposition the distal cap portion relative to the distal end of the elongated catheter while the expandable body is positioned within the intervertebral disc space.

摘要： Devices and methods are provided for controlling and indicating the deployed length of an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. Devices for controlling the length of the interventional element include gear driven actuators, motors, and other mechanisms. Devices for indicating length of an interventional element to the user include sensors, detents, visual displays and other mechanisms providing visual, audible, and tangible indications of length to the user. The control and indication devices preferably work in tandem to enable highly precise adjustment of interventional element length.

摘要： Flexible high-pressure angioplasty balloons are disclosed herein which utilize an inflatable balloon positioned upon the catheter and a supporting structure secured over or along the catheter at a first location proximal to the balloon and at a second location distal to the balloon. Inflation of the balloon reconfigures the supporting structure to urge the first location and the second location towards one another thereby inhibiting longitudinal elongation of the balloon relative to the catheter. The supporting structure may surround, support, or otherwise extend over the entire length of the balloon and allows for the balloon to retain increased flexibility which enables the balloon to bend or curve even at relatively high inflation pressures.

摘要： An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending there between, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.
