An ablation catheter including an elongate shaft, an inflatable balloon positioned at a distal region of the elongate shaft, a first ablation electrode disposed outside of and carried by an outer surface of the inflatable balloon, a first ultrasound transducer disposed outside of the inflatable balloon, and a flexible circuit. The flexible circuit includes a first conductor and a second conductor and is disposed outside of and carried by the outer surface of the inflatable balloon. The first conductor is in electrical communication with the first ablation electrode, and the second conductor in electrical communication with the first ultrasound transducer.

Cardiac ablation catheters and methods of use. Catheters that include an expandable membrane, an imaging member disposed within the expandable membrane, the imaging member having a field of view, a light source disposed within the expandable member adapted to deliver light towards the field of view of the imaging member, and an electrode comprising an outer conductive layer and inner light absorbing layer disposed between the electrode and the expandable membrane, the inner light absorbing layer adapted to absorb light from the light source and thereby reduce reflection of the light from the outer conductive electrode.

Surgical devices and methods of operation thereof are provided herein. The surgical devices include interior walls defining a cavity that extends along a first axis and having an aperture at a first end of the surgical devices. The surgical devices include a backstop spaced apart from the aperture and having a surface opposing the aperture. The surgical devices include an arm that extends from the surgical device. The surgical devices are configured to receive a fiber waveguide into the cavity at a second end. The surgical devices of some embodiments include a surface for reflecting laser light from the fiber waveguide.

A phototherapy shield for an infant includes a shield body that is sized and shaped to extend around at least a portion of a torso of an infant. The shield body includes a reflective foil layer that is sandwiched between an upper fabric layer and a lower fabric layer and that is configured to block phototherapy light. A fastener is attached to the shield body to secure the phototherapy shield around the infant's torso. The disclosed phototherapy shield and associated methods are useful for shielding an infant undergoing phototherapy, and more particularly, for shielding the chest of a premature infant undergoing phototherapy to treat jaundice. The shield body can be sized and shaped to cover the infant's chest over the second to fourth thoracic rib position to shield an area of skin above a patent ductus arteriosus (PDA).

Systems, devices, and methods for identifying a target in vivo are disclosed. A target identification system for use in electrosurgery includes a probe, an optical splitter, and a spectroscopy system. The probe includes an optical pathway to pass a first optical signal to an anatomical target and at least a portion of a second optical signal from the anatomical target. The optical splitter includes a first port to direct the first optical signal to the optical pathway and to receive the at least a portion of the second optical signal from the optical pathway, a second port to receive the first optical signal, and a parabolic reflector to redirect the portion of the second optical signal. The spectroscopy system can identify a characteristic of the anatomical target based on the redirected at least a portion of the second optical signal.

Visualization and ablation systems and catheters. The systems can capture a plurality of different 2D images of the patient's anatomy adjacent an expandable member, each of which visualizes at least one part of the patient that is in contact with the expandable membrane, tag each of the plurality of different 2D images with information indicative of the position and orientation of a locational element when each of the plurality of different 2D images was captured, create a patient map, wherein creating the patient map comprises placing each of the plurality of different 2D images at the corresponding tagged position and orientation into a 3D space, and display the patient map.

An imaging system includes an image generating device and two reflecting mirrors. The image generating device projects a light toward a gravity direction. The two reflecting mirrors are disposed with respect to each other and one of the two reflecting mirrors is disposed with respect to the image generating device. The light projected by the image generating device forms a virtual image through the two reflecting mirrors in sequence.

Described herein are loupes shields. The shields can be easily attached to the loupes. The loupes shield is composed of a single filter that blocks harmful light. Additionally, the loupes shield includes a connector that permits the loupes shield to be attached to the loupes lens or housing that holds the loupes lens. The loupes shields described are useful in applications where it is desirable to protect the user from being exposed to damaging light. The loupes shields are useful in dental applications such as, for example, dental restorations, where light cure is required to cure the resin applied to a tooth during a dental restoration.
