  • Patent number: 11179175
    Abstract: Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

  • Patent number: 11172863
    Abstract: A system and method for detecting and verifying bradycardia/asystole episodes includes sensing an electrogram (EGM) signal. The EGM signal is compared to a primary threshold to sense events in the EGM signal, and at least one of a bradycardia or an asystole is detected based on the comparison. In response to detecting at least one of a bradycardia or an asystole, the EGM signal is compared to a secondary threshold to sense events under-sensed by the primary threshold. The validity of the bradycardia or the asystole is determined based on the detected under-sensed events.

  • Patent number: 11116941
    Abstract: Catheter curve shape struts for steerable medical devices such as catheters are disclosed. These struts may not only help shape a steerable portion of a medical device (e.g., a distal portion of a catheter), but also may help to return a steered or deflected portion of the medical device to an uncurved configuration when it is no longer desirable or necessary to steer or deflect the medical device. These struts may include first and second pluralities of complementary, staggered cutout regions. When used in a catheter that is deployed via an introducer, at least some configurations of the catheter curve shape strut can enable the catheter to be rotated about its longitudinal axis, even when the distal deflectable section is in a curved configuration and inside of the introducer.

By providing the pull wire ring (100a-e) with an eccentric recess (105a-f) which defines a passage between a first end face (101) and a second end face (105) of the ring, it becomes possible to guide ancillary elements such as electrical lines, data cables and fiber optics past the pull wire ring (100a-e) further towards the distal end of the steerable medical device. By this measure, functionality of the distal end of the medical device is enhanced without obstructing a main lumen of the device.

  • Patent number: 10610297
    Abstract: A device for treating spinal tissue of a patient's body may include an energy source and first and second probe assemblies. Each of the probe assemblies may have an electrically conductive energy delivery device electrically coupled to the energy source, and may also have an electrothermal device for cooling the probe assembly. The device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies. Related methods of use include cooling, at times via an electrothermal device.

  • Patent number: 10568688
    Abstract: An ablation catheter comprises an elongate catheter body and a branch electrode element. The elongate catheter body has a central axis, a distal end, and a proximal end. The elongate catheter body is configured to be steered within a heart chamber. The branch electrode element has a base end and a working end or tip. The base end is secured to the elongate catheter body at a location spaced proximally of the distal end and an effector on the working end. The branch electrode element is configured to evert when the distal end of the elongate catheter body is in a pulmonary vein ostium or os so that the effector can be selectively engaged against locations surrounding the pulmonary vein os which differ in radial direction and distance. One or more of linear or curved ablation patterns are generated on tissue adjacent the pulmonary vein os with the effector.

  • Patent number: 10549035
    Abstract: An intrathecal delivery system for a pharmaceutical includes a reservoir containing a volume of the pharmaceutical agent, and a pump configured to deliver a portion of the pharmaceutical agent contained in the reservoir. A controller is configured to receive biological cycle information pertaining to a biological cycle (e.g., cardiac cycle), and configured, based on the received biological cycle information, to control the pump to deliver the pharmaceutical agent into a patient's intrathecal space as a high-speed bolus at a time corresponding to a time determined based on Processing the biological cycle information. The high-speed bolus may be delivered at a rate of 10-100 ?L per second. The timing of such delivery corresponds to a time within the biological cycle when cerebrospinal fluid flow is optimal for intrathecal delivery of the pharmaceutical agent. Conditions for which treatment is enhanced by the intrathecal delivery system include refractory hypertension, spasticity and chronic pain management.

  • Patent number: 10518081
    Abstract: Medical leads include a lumen body at an end of the lead, and the lumen body includes multiple filar lumens. The lumen body is joined to a lead body, and electrical connectors are longitudinally spaced along the lumen body. Filars within the filar lumens are directed through filar passageways within the lumen body to attach to the electrical connectors on the lumen body. The filar passageways may be aligned with the filar lumens, and slots within the electrical connectors may be aligned with the filar passageways to facilitate assembly. The lumen body may provide additional stiffness to the end of the lead where the lumen body is located to facilitate lead insertion into the medical device. The filar lumens of the lumen body may have a longitudinally straight configuration so that the portions of filars within the filar lumens are held in a longitudinally straight configuration.
