SELF-HOLDING MEDICAL DEVICE CONTROL HANDLE WITH CAM ACTUATED CLUTCH MECHANISM
A medical device control handle has a first actuation assembly and a second actuation assembly, wherein each assembly has a shaft that is axially aligned but not rotationally coupled with the other shaft. The first actuation assembly includes a first actuation member and a clutch mechanism having a friction disk for generating frictional torque in rendering the first actuation member self-holding. The first actuation member has a cam portion adapted to impart translational motion and rotational motion for disengaging the clutch mechanism upon pivotation of the first actuation member, thus allowing rotation of the first shaft to manipulate a feature of the medical device, for example, deflection. The second actuation assembly includes a second actuation member and a translating member that is responsive to rotation of the second shaft so as to manipulate another feature of the medical device. The second actuation member is also self holding.
EXTERNAL PACING DEVICE WITH DISCOMFORT MANAGEMENT
An external medical device includes a user interface; at least one therapy electrode configured to be disposed on a patient; and a processor operatively coupled to the at least one therapy electrode, the processor configured to cause a treatment manager to detect a cardiac condition of the patient; receive, via the user interface, discomfort information descriptive of the discomfort experienced by the patient; responsive to determining from the discomfort information that the patient is unconscious, execute at least one pacing routine, the at least one pacing routine being associated with the cardiac condition; and responsive to determining from the discomfort information that the patient is conscious, adjust at least one characteristic of the at least one pacing routine.
Medical monitoring and treatment device with external pacing
A non-invasive bodily-attached ambulatory medical monitoring and treatment device with pacing is provided. The device includes at least one therapy electrode; a memory storing information indicative of a patient's cardiac activity; circuitry for implementing a plurality of pacing routines, each pacing routine of the plurality of pacing routines corresponding to at least one cardiac condition of a plurality of cardiac conditions; and at least one processor coupled to the circuitry and configured to identify, within the information, at least one cardiac condition of the plurality of cardiac conditions; and respond to the identified cardiac condition in part by causing execution of at least one pacing routine corresponding to the identified cardiac condition.
Angiosome-based perfusion monitoring system
A compression device includes at least one pressurizable bladder to substantially occlude blood flow into skin capillary beds adjacent to the at least one pressurizable bladder, and a plurality of perfusion sensors. In operation a first-angiosome sensor detects the perfusion parameter of a skin capillary bed in a first angiosome of the limb, and a second-angiosome sensor detects the perfusion parameter of a skin capillary bed in a second angiosome of the limb that is different from the first angiosome. A control circuit maps sensor signals from the first-angiosome sensor to the first angiosome or a first artery of the limb, and maps sensor signals from the second-angiosome sensor to the second angiosome or a second artery of the limb different from the first artery of the limb. For each perfusion sensor, the control circuit determines whether the received sensor signals are indicative of peripheral artery disease.
MEDICAL DEVICE WITH ACOUSTIC SENSOR
In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one electrocardiogram (ECG) electrode, at least one acoustic sensor, and at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one therapy electrode. The at least one processor can receive at least one acoustic signal from the at least one acoustic sensor, receive at least one electrode signal from the ECG electrode, detect at least one unverified cardiopulmonary anomaly using the at least one electrode signal, and verify the at least one unverified cardiopulmonary anomaly with reference to data descriptive of the at least one acoustic signal.
DEVICE AND METHOD FOR DETERMINING ANALYTE LEVELS
Devices and methods for determining analyte levels are described. The devices and methods allow for the implantation of analyte-monitoring devices, such as glucose monitoring devices that result in the delivery of a dependable flow of blood to deliver sample to the implanted device. The devices include unique architectural arrangement in the sensor region that allows accurate data to be obtained over long periods of time.
BASKET STYLE CARDIAC MAPPING CATHETER HAVING AN ATRAUMATIC, METALLIC TWO-PART DISTAL TIP FOR DETECTION OF CARDIAC RHYTHM DISORDERS
A system for sensing multiple local electric voltages from endocardial surface of a heart, includes: an elongate tubular member having a lumen, a proximal end and a distal end; a plurality of flexible splines; an anchor for securably affixing the proximal portions of the splines, where the anchor is securably affixed within the lumen of the elongate tubular member at the distal end of the elongate tubular member; and a metallic tip for securably affixing the distal portions of the splines.
CONTROL HANDLE WITH ROTATIONAL CAM MECHANISM FOR CONTRACTION/DEFLECTION OF MEDICAL DEVICE
A medical device has a distal member with a configuration that can be changed by means of a control handle with a control assembly employing a rotational cam, a shaft, and a pulley, where the rotational cam is rotationally mounted on a portion of the control handle for rotation by a user. The rotational cam operates on the shaft to move it proximally or distally depending on the direction of rotation which in turn rotates the pulley to draw or release a puller wire to change the configuration of the distal member of the medical device. The shaft is oriented along a diameter of the control handle. The shaft has two ends which extends through two axial guide slots in the portion of the control handle to sit two opposing helical tracks formed on inner surface of the rotational cam. The guide slots are parallel with the longitudinal axis of the control handle and therefore maintain the shaft's diametrical orientation as the rotational cam is rotated to move the shaft proximally or distally. Actuation of the puller wire by means of the control assembly can result in a change of the distal member's configuration, including deflection, contraction and/or expansion.
External pacing device with discomfort management
An external medical device includes at least one therapy electrode configured to be disposed on a patient; and a treatment manager configured to execute a baseline process to determine at least one of a range of values for a discomfort parameter and a patient discomfort threshold value corresponding to the at least one pacing routine, detect a cardiac condition of the patient, execute the at least one pacing routine, the at least one pacing routine being associated with the cardiac condition, monitor the discomfort parameter during execution of the at least one pacing routine, determine whether the discomfort parameter transgresses the at least one of the range of values and the patient discomfort threshold value, and adjust at least one characteristic of the at least one pacing routine upon the discomfort parameter transgressing the at least one of the range of values and the patient discomfort threshold value.
Magnetic field generator with minimal image occlusion and minimal impact on dimensions in C-arm x-ray environments
A magnetic field generator assembly (44) is configured to be associated with a table (20) supporting a body. The magnetic field generator comprises magnetic field transmitters (57A) that are thin (of minimal height) and transparent, or substantially transparent, to x-ray radiation. The magnetic field transmitters (57A) are configured to minimally obstruct components of an imaging system and to minimally interfere with image quality. A plurality of transmitters is arranged in a first layer of the assembly. Each transmitter (57A) comprises an elongate conductive element, such as a wire, arranged in a spiral form, such as a coil.
