A method and system for determining changes between a planning image and a treatment image of a subject is described. The method comprising the steps of: defining one of more clinical volumes on the planning image of a subject and defining a planning envelope volume around the clinical volume for the planning image; acquiring a treatment image from the subject for a location corresponding to the location of the planning image; wherein the treatment image will have the same planning envelope volume as the planning image; determining the location of the one or more clinical volumes on the treatment image relative to the planning envelope volume; determining an encapsulation metric for one or more of the clinical volumes defining the extent of encapsulation of the clinical volume on the treatment image within the planning envelope volume on the treatment image.

A medical device for occluding the left atrial appendage is disclosed. The medical device for occluding the left atrial appendage includes an expandable member having a first end region, a second end region and an inner cavity. The medical device also includes a plurality of spine members coupled to the expandable member, the plurality of spine members spaced circumferentially around an outer surface of the expandable member. Additionally, the medical device includes a valve member extending at least partially into the inner cavity, wherein the plurality of spine members are configured to position the medical device within an opening of the left atrial appendage and wherein the expandable member is configured to expand and seal the opening of the left atrial appendage.

A device comprising an image sensor for capturing a stream of asynchronous data representing per-pixel changes in radiance within a scene over an acquisition cycle and processing circuitry communicatively coupled to at least one light source positioned to illuminate at least an area of the scene, the processing circuitry configured to modulate output of the at least one light source over the acquisition cycle.

The electric compressor (120) is arranged in the compressor housing section (112). The heater (130) comprises a heating element (132) and a coolant channel (134) including coolant ports (136). The control electronics (140) comprises a circuit board (142). The electric connectors (150) are electrically connected to the control electronics (140). The heater (130) and the control electronics (140) are arranged within the control housing section (114). The control housing section (114) is arranged axially adjacent to the compressor housing section (112). The coolant ports (136) and the electric connectors (150) are arranged at the control housing section (114) and are oriented in the same direction.

An electric machine includes a machine housing, a stator including a stator core defining a stator core interior and a plurality of windings including first and second end windings, and an internal core including first and second upper portions and first and second lower portions. The electric machine additionally includes a first outer insert engaged with the first upper portion, a second outer insert engaged with the second upper portion, a first inner insert engaged with the first lower portion, and a second inner insert engaged with the first lower portion. The first outer insert, the first inner insert, the first upper portion, and the first lower portion collectively define a first cooling channel for encapsulating the first end windings, and the second outer insert, the second inner insert, the second upper portion, and the second lower portion collectively define a second cooling channel for encapsulating the second end windings.

An electric machine includes a machine housing, and a stator including a stator core defining a stator core interior and a plurality of windings disposed in the stator core interior. The plurality of windings has first and second end windings. The electric machine further includes an internal core surrounding the plurality of windings within the stator core interior. The internal core includes a first upper portion, a second upper portion, a first lower portion, and a second lower portion. The electric machine includes a first insert surrounding the first plurality of windings. The first insert is engaged with the internal core to define a first cooling channel for encapsulating the first end windings. The electric machine also includes a second insert surrounding the second plurality of windings. The second insert is engaged with the internal core to define a second cooling channel for encapsulating the second end windings.

An electric machine includes a first cooling channel encapsulating first end windings, a second cooling channel encapsulating second end windings, a first supply path, and a second supply path. The electric machine includes a first outlet path configured to receive fluid from a first outlet fluidly coupled to the first cooling channel and a first outlet path, and a second outlet path configured to receive fluid from a second outlet fluidly coupled to the second cooling channel and a second outlet path. The first supply path is fluidly separate from the second supply path. The first cooling channel is configured such that, when the fluid is pressurized, the fluid flows from a first lower cooling portion to a first upper cooling portion and such that, when the fluid is not pressurized, the fluid does not flow from the first lower cooling portion to the first upper cooling portion.

One aspect of the present disclosure relates to a light detection and ranging (LIDAR) system comprising: a laser source that is configured to generate a beam; and a transceiver configured to generate a transmit signal based on the beam and transmit the transmit signal through a transmission waveguide and to receive a return signal reflected by an object through a receiving waveguide. The LIDAR system further comprises one or more optics external to the transceiver and configured to optically change a distance between the transmit signal and the return signal by displacing one signal of the transmit signal or the return signal, wherein the one signal before the displacement and the one signal after the displacement are parallel to each other.

A minimally invasive endoluminal annuloplasty system and method of use includes a guide catheter configured to direct a working catheter to a treatment site within a cardiac cavity. The guide catheter may be translatably disposed within the working catheter which may be translatably disposed within an introducer sheath that extends into the cardiac cavity. The guide catheter may be sized to reduce noise, and/or may be formed from a material that assists with visualization. In one embodiment the guide catheter comprises a distal guidewire anchor. Visualization may be used to embed the distal guidewire anchor into tissue at the target site.

A novel embodiment of a pump system, for example, of the type that would be used in a wearable drug delivery system, comprises, in a preferred embodiment, a reservoir, a plunger, disposed within the reservoir and driven by a scissor mechanism connected to a drive mechanism through a linkage, such that a force imparted by the drive mechanism in causes the scissor mechanism to expand thereby causing the plunger move within the reservoir to force a liquid drug contained within the reservoir through a fluid port to a patient.
