Abstract: A replacement heart valve prosthesis is loaded onto a balloon mounted onto a balloon shaft of a catheter system. The balloon shaft is rotatably engaged with an actuator on the handle of the catheter system. Rotation of the actuator by a first amount in a first direction permits rotation of the heart valve prosthesis by a known amount during the procedure so that alignment of the commissures of the replacement valve with the commissures of the existing valve can be predictably achieved.

Abstract: A business method includes imaging documents with an imaging device placed at a location. Media usage is monitored over a cellular network. Upon the media reaching a predetermined level, workers provide additional media. Workers exist in the “gig” economy and have preplaced media. No longer do users change or swap media in media trays. Packaging materials bundle the media. For use, only a portion of the packaging materials is opened thereby revealing an end of the media. Both the packaging materials and the exposed media are inserted into a reusable media shell in a manner making the media available for picking by the imaging device. Other embodiments are envisioned.

Abstract: A medical device may include an elongated body, a balloon positioned at a distal portion of the elongated body, and one or more pressure-wave emitters positioned along a central longitudinal axis of the elongated body within the balloon. The one or more pressure-wave emitters may be configured to propagate pressure waves radially outward through the fluid to fragment a calcified lesion at the target treatment site. The at least one of the one or more pressure-wave emitters may comprise an electronic emitter including a first electrode and a second electrode. The first electrode and the second electrode may be arranged to define a spark gap between the first electrode and the second electrode, and the second electrode may comprise a portion of a hypotube.

Abstract: A multi-dimensional encoder (“MDE”) receives a file with different data points. Each data point is defined with uncompressed multi-dimensional data. The multi-dimensional data may include multiple elements for defining a data point position (e.g., a multi-dimensional position including x, y, and/or z coordinates), color values of the data point (e.g., red, green, and blue), and/or other data point attributes. The MDE assigns an index to each data point or each data point element, and maps the data points to a frequency domain based on a frequency with which values occur in two or more of the elements (e.g., multiple dimensions). The MDE generates a line that represents the frequency, and provides a compressed file format to a requesting device that includes the line and different sets of indices that are associated with different frequencies represented by the line.

Abstract: A medical device may include an elongated body having a distal elongated body portion and a central longitudinal axis. The medical device may include a balloon positioned along the distal elongated body portion. The balloon may be configured to receive a fluid to inflate the balloon such that an exterior balloon surface contacts a calcified lesion within a patient's vasculature. The medical device may include one or more pressure wave emitters positioned along the central longitudinal axis of the elongated body. The one or more pressure wave emitters may be configured to propagate at least one pressure wave through the fluid to fragment the calcified lesion. At least one pressure wave emitter may include an optical fiber configured to transmit laser energy into the balloon. The laser energy may be configured to create a cavitation bubble in the fluid.

Abstract: Disclosed is an encoding and decoding system and associated methods for producing a compressed waveform that encodes data points of a point cloud in a format and size that may be transmitted over a data network, decompressed, decoded, and rendered on a remote device without the buffering or lag associated with transmitting and rendering an uncompressed point cloud. The encoder receives a request from a remote device to access the point cloud, encodes a set of data points from the point cloud as one or more signals derived from values defined for the positional and non-positional elements of each data point from the set of data points, generates one or more compressed waveforms from compressing the one or more signals and transmits the one or more compressed waveforms to the remote device in response to the request for decompression, decoding, and image rendering.

Abstract: Disclosed is a system and associated methods for generating a mutable tree to efficiently access data within a three-dimensional (“3D”) environment. The system generates the mutable tree with a root node defined at a root node position, a first branch with nodes for each of a first set of subdivided regions that are a first distance from the root node position, and a second branch with nodes for each of a second set of subdivided regions that are a second distance from the root node position. The system sorts the mutable tree in response to a request to access data from a first position within the 3D environment so that the first node in the first branch is the first subtree node that is closest to the first position, and the first node in the second branch is the second subtree node that is closest to the first position.
