Abstract: A single-piece patient interface device for coupling a patient's eye to an ophthalmic surgical laser system includes a cone substrate with a rigid frustoconical shaped shell for coupling to the laser system, and a flexible suction ring integrally joined to the lower end of the rigid shell for coupling to the patient's eye. The suction ring has a circular skirt extending downwardly from a base portion, a diaphragm extending from the base portion and disposed inside of the skirt, and a contact lens held by the diaphragm to cover a center opening. When the skirt contacts the eye's surface, the skirt, the diaphragm, the contact lens and the eye surface form a vacuum chamber, where a vacuum may be applied to secure the patient interface device to the eye. The parameters of the suction ring are optimized to fit a large range of eye sizes, including smaller eyes.

Abstract: A method used in a corneal lenticule procedure for finding the visual axis location before eye docking, to track the visual axis location displacement during docking, and to center the lenticule incision pattern at the visual axis location after docking, without ink-marking the visual axis location at the center of the cornea with ink or other substance. Two docking illumination beams are illuminated on the eye surface at oblique angles, and a first eye image is taken before docking while the eye looks at the fixation light of the laser system. A second eye image is taken after docking. The pre-docking cornea apex position is obtained based on the two reflected light spots of the docking illumination light. Pupil center is obtained in both images. The post-docking corneal apex is then calculated from the pre-docking cornea apex position and the pre- and post-docking pupil center positions.

Abstract: In an ophthalmic surgical laser system, a patient interface device for coupling a patient’s eye to the laser system includes a lens cone with a frustoconical shaped shell for coupling to the laser system and a suction ring for coupling to the patient’s eye, the lens cone and the suction ring being either joined together by clamping or formed integrally as one piece. A cap is provided for use with the lens cone as an installation aid. In the configuration supplied to the user, the lens cone is partially embedded in and snapped to the cap. The cap has a portion with a relatively large diameter and multiple ribs for easy handling. The user holds the cap to install the lens cone on the laser system, and pulls the cap to unsnap it from the lens cone. The lens cone is attached to the laser system with a bayonet mount.

Abstract: Imaging catheter assemblies as well as related methods of manufacturing and imaging are disclosed. The imaging catheter assembly can include an interior lumen containing an intravascular imaging device as well as an acoustic fluid medium comprising ethanol. Such an imaging catheter assembly can be contained within a package, such that when the imaging catheter assembly is removed from the package it can begin generating image data without needing to perform one or more preparation steps on the imaging catheter assembly. Related methods of manufacturing include applying a vacuum to an interior lumen of an imaging catheter assembly and filling the interior lumen with an acoustic fluid medium comprising ethanol. After filling the interior lumen, the imaging catheter assembly is packaged within a packaging container for later use.

Abstract: An ablation probe for treating and imaging body tissue includes an ablation electrode tip including an ablation electrode configured for delivering ablation energy to body tissue. A plurality of acoustic openings are disposed through the ablation electrode tip. A plurality of ultrasonic imaging sensors are positioned inside the ablation electrode tip. The ultrasonic imaging sensors are configured to transmit ultrasonic waves through the acoustic openings. A plurality of flex circuits are each electrically connected to one of the plurality of ultrasonic imaging sensors.
