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.

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: The present disclosure relates to medical devices. More particularly, this disclosure describes a vascular device allowing large bore transseptal access with subsequent atrial re-access by preplacing closures/tissue approximating sutures prior to creating a septostomy. Generally, the device may include a delivery catheter for puncturing and cutting the interatrial septum.

Incisions may be made by an expandable cutting implement which may use mechanical or radio frequency (RF) energy without interfering with the suture. A therapeutic instrument may be advanced through the tissue plane after the incisions are made by the cutting implement. Closure of the incision may be performed with the previously placed sutures.

Abstract: Examples related to methods and systems for analyzing presentation digital data, which may include extracting speaker audio data from the audio data of the presentation digital data and analyzing the speaker audio data to identify a characteristic of the speaker audio data, such as tone, frequency, cadence, and volume.

The identified portions of the presentation digital data and associated tags are stored for retrieval. This method provides a way to efficiently analyze presentation digital data and retrieve specific portions of interest based on the characteristic of the speaker audio data.
