A multilayer board includes: a front-side layer; an intermediate layer; a back-side layer; the front-side layer; a first ground terminal and a second ground terminal for connecting ground lines of a plurality of shield lines to be connected to the multilayer board; a plurality of signal line connecting terminal arrays each including a plurality of signal line connecting terminals for connecting respective signal lines of the shield lines; and a wire having a thermal conductivity, the wire extending to the second end on the intermediate layer.

Disclosed is an intraluminal imaging system that includes an intraluminal imaging catheter or guidewire configured to obtain imaging data associated with a lumen of a patient while positioned within the lumen, and a processor in communication with the intraluminal imaging catheter or guidewire. The processor is configured to generate aplurality of image frames using on the imaging data, automatically measure an anatomical feature in the image frames, identify a target frame representative of a region of interest, identify a proximal reference frame located proximal of the target frame, and identify a distal reference frame located distal of the target frame. The processor is also configured to output a single screen display including the proximal reference frame, target frame, distal reference frame, and a longitudinal representation of the lumen showing the respective positions of the proximal refernce frame, the target frame, and the distal refernce frame.

An intraluminal imaging device includes a flexible elongate member configured to be positioned within a body lumen of a patient. The flexible elongate member includes a plurality of coaxial cables. Each of the plurality of coaxial cables includes a conductive shield layer. The intraluminal imaging device also includes an ultrasound imaging assembly positioned at a distal portion of the flexible elongate member and in communication with the plurality of coaxial cables. The ultrasound imaging assembly includes a transducer array configured to obtain ultrasound data and a conductive pad. The conductive shield layer of each of the plurality of coaxial cables is mechanically and electrically coupled to the conductive pad. Associated devices, systems, and methods are also provided.

A vapor delivery system is provided that may include any of a number of features. One feature of the vapor delivery system is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, or denature the prostate. In some embodiments, the vapor delivery system can include safety features including prostate capsule detection, needle tracking, and treatment tracking. Methods for safe and effective treatment of prostate tissues are presented.

For intraluminal ultrasound probes, two long-thin arrays (e.g., 1D arrays) are provided in the intraluminal ultrasound probe for bi-plane imaging. The arrays are rotatable relative to each other so that during insertion the arrays align to be long and thin, allowing the shaft of the probe to be narrow. For bi-plane imaging after insertion, one array is rotated relative to the other array, defining two non-parallel imaging planes.

Systems and methods for cardiac pacing are provided, where a pacing lead is placed at or near the bundle of His. A method for pacing a heart of a patient comprises: introducing a sheath to vasculature of the patient; steering the sheath within a coronary sinus in the heart to lodge a distal end of the sheath to a target location proximal to the bundle of His above a septum separating a left ventricle and a right ventricle of the heart; advancing a pacing lead through a lumen of the sheath to the target location; coupling the pacing lead to cardiac tissue at the target location; removing the sheath; and electrically pacing the bundle of His using the pacing lead.
