Abstract
A method and system for treating pain using an implanted spinal cord stimulation system monitors patient activity levels over a baseline period to determine a baseline activity level. High and low activity thresholds are set relative to the baseline to define activity ranges. The system monitors patient activity during a monitoring period to determine if measured activity falls within the high or low activity ranges. When activity exceeds the high threshold, a first stimulation bolus is scheduled. When activity falls below the low threshold, a second stimulation bolus is scheduled. The system can track effectiveness of the stimulation and modify parameters based on monitored responses.

A surgical system for use with a surgical robot may include an endoscope including a handle and an elongate shaft extending distally from the handle, an attachment mechanism including a fixture configured to receive the handle of the endoscope and a mounting structure configured to attach the fixture to the surgical robot, a motorized introducer apparatus spaced apart from the surgical robot and configured to translate the elongate shaft of the endoscope relative to a patient, and an input device configured to be operated using one hand only. The input device may include a plurality of tactile buttons operable using the one hand, and a joystick configured for operation by a thumb of the one hand. The input device may include a plurality of motion sensors configured to determine position and orientation of the input device in space.

Thrombectomy catheter and high-pressure protection systems for protecting a catheter shaft from high-pressure fluid jets. An illustrative thrombectomy catheter may comprise a catheter body including a catheter lumen extending therethrough. A high-pressure fluid supply tube extends through the catheter lumen from the catheter body proximal end region toward the catheter body distal end region. The high-pressure fluid supply tube is configured for communication with a fluid source near the catheter body proximal end region. The high-pressure fluid supply tube includes jet orifices for expelling fluid jets from the high-pressure fluid supply tube within the catheter lumen. Reinforcement members are disposed within the catheter lumen such that fluid jets expelled from the jet orifices impinge against the reinforcement members.
Systems, methods, and devices involve approaches for detecting a first set of acceleration data collected at a first sampling frequency; determining that the first set of acceleration data contains noise less than a threshold; and detecting a second set of acceleration data collected at a second sampling frequency that is higher than the first sampling frequency.
Systems and methods for detecting cardiac arrhythmia are discussed. A medical-device system includes an arrhythmia detector circuit and an event prioritizer circuit. The arrhythmia detector circuit can detect an atrial activation event from a cardiac electrical signal sensed from the patient, and determine an atrial fibrillation (AF) confidence indicator based on a signal characteristic of the atrial activation event. The event prioritizer circuit can generate an event priority for the AF event based on the AF confidence indicator. Multiple AF events may be prioritized in a specific order and presented to a user or a process.
A clipping system includes a clip, an extension member, and a handle. The handle includes a body, a component and a flexible member. A proximal end of the member is coupled to the component so that longitudinal motion of the component along the body moves the member to transition the clip between insertion, initial deployment, and review configurations. The flexible member extends along a surface of the body to a distal end comprising a pin extending toward the surface which includes a track. The track has a non-uniform depth and variable depth features at locations along the track for resisting movement of the pin so that, as the component moves along the body and the pin travels within the track, the pin encountering the variable depth features along the track provides feedback regarding a position of the clip relative to the endoscope.

END CAP HAVING ONE OR MORE ELECTRODES, RELATED SYSTEMS
Medical systems are described, including a medical system including a medical device and an end cap. The medical device includes a handle and a shaft extending distally from the handle to a distal end. The shaft includes a working channel. The end cap is coupled to the distal end of the shaft and includes a first portion, a second portion, and a protrusion. The first portion has a lumen and the distal end of the shaft is positioned within the lumen. The second portion extends distally from the first portion and includes a wall defining a chamber. The chamber is in communication with the working channel of the shaft. The protrusion extends distally from the second portion and a distal end of the protrusion includes an electrode.
Vascular closure devices as well as methods for making and using vascular closure devices are disclosed. An example vascular closure device may include an intravascular sealing member configured to be disposed within a blood vessel. The vascular closure device may also include an extravascular hemostatic member configured to be disposed adjacent to an exterior of the blood vessel. The vascular closure device may also include an extravascular sealing member configured to be disposed along an outer surface of the extravascular hemostatic member. A suture may be coupled to the intravascular sealing member and the extravascular sealing member. At least one of the intravascular sealing member, the extravascular hemostatic member, the extravascular sealing member, and the suture may include a radiopaque material.

STENT SELECTION AND DISPLAY FOR POST PERCUTANEOUS INTERVENTION INTRAVASCULAR IMAGING
The present disclosure provides to generate a graphical user interface to visually depict stents detected from intravascular image frames and to provide for navigating between multiple detected stents via the GUI to select one of the depicted stents for interrogation. Further, the disclosure provides to update the GUI to depict assessments for the selected stent.
