    摘要: A stiffenable balloon catheter assembly capable of being converted from an “over-the-wire” mode with respect to a guidewire extending therethrough to a “rapid-exchange” mode with respect to a guidewire extending therethrough, and vice versa. The catheter has a plurality of lumens, one lumen however, having a side opening with an obstructable galp, the orientation of which, determines the utilization “mode” of the catheter assembly. Stiffening stylets may be adjustably locked into the lumens, depending upon the “mode”, to control the stiffness of the catheter assembly during its utilization within a patient.

    摘要: An elongated image-carrying member that enables microendoscopy to be practiced using normal-sized catheters, includes a drawn, fused, central multi-fiber micro-unit of about 0.5 mm diameter, having about 2,000 glass fibers in coherent array, with a polymeric coating bonded to its pristine as-drawn outer surface. This combination achieves sufficient flexibility and optical qualities to enable effective use to provide vision for inspection of small passages and ducts. Flexible image-carrying members having diameter of 0.5 millimeter or less and catheters of diameter of 3 mm or less incorporating such members and effective working channels are achievable. For vision in remote areas, the micro-unit is employed with a substantially spherical lens with an ocular system for providing a focus range from less than about 2 mm to infinity and having resolution of detail down to the order of about 0.001 inch. The micro-optical member may be employed with a handpiece in a vision system, the micro-optical member being joined to the handpiece by a detachable connector having a stepped structure for precise alignment between the handle and the micro-optical member. By application of a relatively thin coating containing an opaque constituent to the as drawn micro-unit, degradation of the image and avoidance of artifacts caused by wave guiding effect are avoided. Devices with varying bend radiuses are also shown.

    摘要: An expansible balloon catheter has at least a first exterior surface with a given coefficient of friction and a second exterior surface with a greater coefficient of friction. In a compact form only the first exterior surface is exposed to produce a low coefficient of friction during transfer of the collapsed or uninflated balloon to and across a lesion. When inflated, the second surface dominates the first surface and produces an increased coefficient of friction overall thereby to stabilize the balloon in the lesion.

    摘要: A catheter device and method for heating tissue, the device having a catheter shaft constructed for insertion into a patient's body, and at least one chamber mounted on the catheter shaft. The catheter shaft has at least one lumen for fluid flow through the shaft. The chambers are defined by walls that are at least in part expandable. Fluid flows, through the lumens, between the chambers and a fluid source outside the body. The chambers can be filled with the fluid after they have been placed within the body. A heating device heats liquid within at least one of the chambers, so that heat is transmitted from the liquid to surrounding tissue by thermal conduction through the wall of the chamber. Means are provided for selectively directing heat transmission toward a selected portion of surrounding tissue. The chambers are fillable with fluid separately from each other, so that the chambers can occupy any of a plurality of possible total volumes. By selecting the total volume of chambers, compression of the tissue can be controlled, and hence the effectiveness of transfer of heat to the tissue can be controlled. According to the method, the catheter device is used to heat tissue from within a duct in a patient's body. The chambers are inserted into the duct and filled with fluid. Liquid is heated within at least one of the chambers, and heat is selectively directed toward a selected portion of surrounding tissue.
