摘要： A dual braided catheter shaft includes an inner helical braid and outer helical braid than encapsulate an axially extending steering wire there between. In one embodiment, the shaft includes an inner polymer jacket, an inner braid formed on the inner jacket, a steering wire disposed along an outside surface of the inner braid, an outer braid formed over the inner braid and steering wire assembly and an outer jacket formed on the outer braid. The braiding parameters of the inner and outer braids can be varied along the length of the catheter to provide varying mechanical properties.

摘要： The invention comprises self-lubricating polymer compositions that are especially useful in medical devices and valves and gaskets of medical devices. In a preferred embodiment, the polymer compositions comprise a thermosetting or thermoplastic silicone elastomer in combination with a lubricity enhancing polyfluoropolyether fluid or hydrocarbon-based synthetic oil. In other preferred embodiments, the polymer compositions contain only biocompatible components. The improved anti-friction properties of the self-lubricating polymers can be demonstrated over a course of insertion and withdrawal cycles, where conventional polymers have changing and mostly increasing force required for each insertion and withdrawal, while the polymer compositions of the invention remain stable.

摘要： An irrigated ablation electrode assembly comprises a distal member, a first manifold, and a second manifold. The distal member includes an outer surface; an inner surface; and at least one radially extending passageway that extends from the inner surface of the distal member to the outer surface of the distal member. The first manifold includes an outer surface, an inner cavity, and at least one radially extending passageway that extends from the inner cavity to the outer surface of the first manifold. The second manifold includes an outer surface, an inner surface, and at least one radially extending passageway that extends from the inner surface of the second manifold to the outer surface of the second manifold. Other irrigated ablation electrode assemblies are also presented.

摘要： The present invention is an electrophysiology, RF ablation, or similar catheter (i.e., catheter or sheath) that includes an actuator that significantly increases the length of travel (i.e., steering travel) of the actuation wires, as compared to the length of travel provided by prior art actuators. The catheter includes a hollow flexible tubular body, a pair of actuation wires disposed in a side-by-side relationship in the body, a handle attached to a proximal end of the body, an actuator pivotally mounted to the handle, an arcuate internal gear rack disposed on the actuator, one or more pulleys pivotally mounted on the handle and coaxially coupled to a pinion gear engaged with the gear rack, and a guide block mounted within the handle. The one or more pulleys include a first channel in which the first actuation wire resides and a second channel in which the second actuation wire resides. The actuation wires pass through holes in the guide block, which aligns the wires into their respective channels. The actuation wires enter into their respective channels on opposite sides of the axis of the one or more pulleys. As the actuator is pivoted relative to the handle, the gear rack rotates the pinion gear and the one or more pulleys. This causes one of the actuation wires to be in-hauled (i.e., wound about the one or more pulleys) and the other actuation wire to be paid-out (i.e., unwound from the one or more pulleys).

摘要： A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis and comprising a distal end and a proximal end; and a plurality of lumens extending along the longitudinal axis of the elongated body, wherein at least one of the lumens is abutting at least another one of the lumens. A catheter comprising the deflectable catheter shaft section and a method of manufacturing the deflectable catheter shaft section are also disclosed. A catheter incorporating a deflectable catheter shaft section can further comprise first and second compression coils disposed over pull wires located within the catheter, wherein the compression coils are unattached to the catheter or components thereof, but can be constrained by a shaft coupler at a distal end of each of the compression coils and by at least a portion of a handle assembly at a proximal end of each of the compression coils.

摘要： An apparatus for detecting deformation of an elongate body may comprise a light source configured to sequentially provide light of multiple frequencies, an optical receiver configured to receive light from the light source, and a filter disposed between the light source and the optical detector. The filter may comprise multiple segments, each of the segments configured to filter light at one of the frequencies so as to alter the amount of light incident on said optical receiver. A total amount of light detected by the optical receiver may change during the sequence so as to be indicative of deformation of the elongate body.

摘要： A method of manufacturing a catheter shaft includes the steps of forming an inner layer of a first polymeric material, forming a plait matrix layer including a second polymeric material about the inner layer, and forming an outer layer of a third polymeric material about the plait matrix layer. The plait matrix layer includes a braided wire mesh partially or fully embedded within the second polymeric material, which is different from at least one of the first polymeric material forming the inner layer and the third polymeric material forming the outer layer. The second polymeric material has a higher yield strain and/or a lower hardness than at least the first polymeric material, and preferably both the first and the third polymeric materials. The first polymeric material and the third polymeric material may be different or the same. The catheter shaft may be formed by stepwise extrusion, co-extrusion, and/or reflow processes.

摘要： An irrigated catheter with uniform cooling and/or uniform fluid distribution in longitudinally spaced apart elution holes by varying the diameter of a fluid delivery lumen. A number of elution holes are provided in a tip region of a catheter body, and these elution holes are in fluid communication with the lumen through ducts. The fluid delivery lumen may be provided with a flow constrictor to restrict flow of fluid towards the distal region.
