    摘要: An ablation catheter comprises: an elongated catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis; a distal member disposed adjacent the distal end, the distal member including an ablation element to ablate a biological member; one or more acoustic transducers disposed in the distal member and each configured to direct an acoustic signal toward a respective target ablation region and receive reflection echoes therefrom; and an acoustic redirection member disposed in the distal member to at least partially redirect the acoustic signal from at least one of the acoustic transducers toward a tissue target. The distal member includes a most-distal portion, a proximal portion, and a deflectable portion between the most-distal portion and proximal portion to permit deflection between the most-distal portion and proximal portion of the distal member. The transducers and redirection member are mounted on opposite sides of the deflectable portion.

    摘要: A mandrel (5) for molding polymer valve leaflets for heart valve prostheses is disclosed, including a body portion (52) including an outer surface with ridges (60) and contoured surfaces (64) corresponding to the leaflets, the upper edge of the contoured surfaces corresponding to the free upper edge of the leaflets, and the mandrel including a mandrel extension (54) above the body portion, and a gap (68) extending around the mandrel between the upper edge of the contoured surface and the mandrel extension. A process for producing these polymer valve leaflets is also disclosed by dip coating with this mandrel and removing the polymer film created at the gap, preferably by applying suction or blowing thereto.

    摘要: A delivery device for a collapsible prosthetic heart valve includes a support shaft around which a compartment for the valve is defined, a distal sheath adapted to selectively cover and uncover the compartment and the valve, and a marker cage having a collapsed condition when the distal sheath covers the compartment and an expanded condition when the compartment is uncovered. The marker cage includes at least one rib having a radiopaque marker for determining the positioning of the valve as it is deployed. The valve may be assembled around the marker cage so that the marker cage does not interfere with the radial expansion of the valve during deployment.

    摘要: Embodiments of the invention provide multi-channel OCT (Optical Coherence Tomography) for imaging biological tissue or the like, and for temperature and/or force sensing, preferably in real time. In one embodiment, an optical signal processing system (200) comprises: a processor (202); a memory (204); a receiving module (210) to receive in real time input from multiple channels of OCT producing interfering optical signals representing multiple measured distances for a target imaging object; a Fast Fourier Transform (FFT) module (212) to apply FFT on the interfering optical signals in real time to produce Fourier frequencies corresponding to the multiple measured distances; and a calculation module (214) to calculate in real time multiple force components of a force applied on the target imaging object to cause at least some of the multiple measured distances for the target imaging object based on the Fourier frequencies from the FFT module.
