Abstract: Apparatus and associated methods relate to diagnostic device and system including a proximal balloon disposed along a length of a catheter and a distal balloon disposed at a distal end of the catheter, with at least one camera disposed at the distal balloon and a pH sensor deployable via inflation of the proximal balloon and configured to engage a patient's esophagus wall to attach the pH sensor to the patient's esophagus wall. In an illustrative example, the pH sensor may be releasably retained to the catheter adjacent to the proximal balloon. The pH sensor may include a tissue engaging feature configured to engage a patient's esophagus wall to attach the pH sensor to the patient's esophagus wall. The diagnostic device may improve upon existing processes by providing a single device to perform a multi-purpose diagnostic procedure.

Abstract: Apparatus and associated methods relate to a catheter manipulation handle with user interface controls for steering a catheter in situ while providing an augmented (e.g., motorized, powered and tunable precision steering, and perforation safeguards) control and feedback user experience. In an illustrative example, the catheter manipulation handle may provide motor assisted operation to automatically rotate and/or deflect a distal tip of the catheter to steer and guide the distal tip to a target location in the patient's vasculature system. The augmented feedback may include, for example, haptic feedback via the handle. Haptic, audible, and/or visual feedback via the handle may indicate, for example, proximity or engagement of the distal tip with sensitive tissue. In some examples, the handle's augmented operation may advantageously amplify feedback signals to enhance the user's perception of the patient's safety with respect to the safe passage of the distal tip through the patient's vasculature.

Abstract: Apparatus and associated methods relate to a wearable compression therapy system for ambulatory therapy, the system including a wearable garment having one or more inflatable chambers, and a pneumatic engine locally coupled to the garment to provide control and inflation of the one or more inflatable chambers. In an illustrative embodiment, the pneumatic engine may control a pump and one or more valves to inflate the inflatable chambers. The valves and pump may be coordinated according to a pre-programmed profile. In some embodiments, the pneumatic engine may have a wireless interface configured to receive control signals from a remote mobile device untethered from the garment. The pneumatic engine may send to the remote mobile device signals indicative of sensed conditions of the compression therapy system. In some embodiments, the pneumatic engine may include a power source that advantageously permits the user to be untethered from a source of power.

Abstract: Apparatus and associated methods relate to an adaptable microenvironment for cellular and biological processing in a traceable, transportable unit. In an illustrative example, an apparatus consists of one or more portable cell tissue containment modules that may be removably interconnected to perform a processing step and/or transfer the stored medium to another module. Associated apparatus and methods are proposed to ensure non-contaminating mechanical or fluid communication between a plurality of modules or between a module and peripheral equipment, to limit process errors such as steps performed out of order, and to intrinsically manage identification of tissue samples with accompanying process data in a manner that decreases risk of mislabeling or otherwise mishandling a sample at all stages of the production and treatment process.

Abstract: Apparatus and associated methods relate to an apparatus for generating a periodic fluid pressure profile. The apparatus may include an enclosure extending longitudinally between an enclosure proximal end and an enclosure distal end. The enclosure may include a radial enclosure port. The apparatus may include an inner pressure profile module (IPPM) configured to rotate about a longitudinal axis and rotate inside of a longitudinally extending central cavity of the enclosure. The IPPM may include a radial IPPM aperture configured to longitudinally align with the radial enclosure port, and a longitudinally extending central cavity of the IPPM. The radial IPPM aperture may have a predetermined aperture shape. The apparatus may include a barrel configured to remain stationary in a longitudinally extending central cavity of the enclosure. The barrel may include a proximal radial barrel aperture and a distal radial barrel aperture.

CPC classification number: F04B43/04 , F04B43/021
Abstract: Apparatus and associated methods relate to nutating a piston drive linkage oriented around a longitudinal axis in response to the rotation of a drive shaft about a drive axis of rotation, said longitudinal axis being offset and canted with respect to said drive axis of rotation. In an illustrative example, the piston drive linkage may be formed as an umbrella shape with multiple arm members extending radially from the longitudinal axis. The distal ends of each of the radial arm members may attach to a stationary piston crank. The nutating motion of the piston drive linkage may impart a substantially linear motion profile substantially parallel to the drive axis of rotation. A shaft extending along the longitudinal axis from the piston linkage may advantageously freely insert into and rotate within a receptacle of a spinner body being rotated around the drive axis of rotation.

Abstract: Apparatus and associated methods relate to a lead that includes metallic traces sandwiched between layers of polymers to form a ribbon (e.g., similar to a flex circuit). In an illustrative example, areas on both ends of the traces may be exposed, forming stimulation electrodes on one end and electrical contacts on the other. The ribbon may be formed such that it fits down a small diameter needle. When the needle is removed, the formed ribbon may relax and engage the tissue providing a means of retention. The lead may advantageously: (1) be minimally invasive to implant, (2) be inexpensive, (3) stay in place a temporary/trial medical procedure setting, and (4) be easy to remove.

Abstract: Apparatus and methods relate to a pneumatic compression therapy device configured to suggest content to the patient based on a determined disease state, the content pertaining to suggested changes in lifestyle based on a standard of care. In an illustrative embodiment, the suggested changes may include modifications to treatment location, treatment time, diet, eating habits, or sleeping schedule. Various examples may further sample the patient's health and automatically adjust a treatment parameter within a predetermined parameter range based on a history of measured parameters, such as limb volume, for example. In coordination with the therapeutic treatment, the therapy device may deliver suggested content to guide the patient to make more healthful lifestyle choices to reduce recovery time and improve patient health outcomes.
