摘要： A fixation mechanism of an implantable medical device is formed by a plurality of tines fixedly mounted around a perimeter of a distal end of the device. Each tine may be said to include a first segment fixedly attached to the device, a second segment extending from the first segment, and a third segment, to which the second segment extends. When the device is loaded in a lumen of a delivery tool and a rounded free distal end of each tine engages a sidewall that defines the lumen, to hold the tines in a spring-loaded condition, the first segment of each tine, which has a spring-biased pre-formed curvature, becomes relatively straightened, and the third segment of each tine, which is terminated by the free distal end, extends away from the axis of the device at an acute angle in a range from about 45 degrees to about 75 degrees.

摘要： A medical device system including an pacemaker implantable in a chamber of a patient's heart is configured to sense near field events from a cardiac electrical signal, establish a lower rate interval to control a rate of delivery of pacing pulses and schedule a first pacing pulse by starting a pacing escape interval set equal to the lower rate interval. The pacemaker withholds the scheduled pacing pulse in response to sensing a near-field event during the pacing escape interval and schedules a next pacing pulse to be delivered at the lower rate interval from a time that the pacing escape interval is scheduled to expire.

摘要： A medical microelectrode includes an elongate electrode body including a tip section, a main body section and, optionally, a coupling section. The tip section, the main body section and, optionally, the coupling section are embedded in a first electrode matrix element, which is substantially rigid, biocompatible and soluble or biodegradable in a body fluid. Additionally the microelectrode includes a dissolution retarding layer on the first electrode matrix element and/or a second electrode matrix element disposed between the first electrode matrix element and the electrode. Upon dissolution or biodegradation of the first electrode matrix element a drug comprised by the first electrode matrix element or the second electrode matrix element is released into the tissue. Also disclosed are bundles and arrays of the electrodes and their use.

摘要： Systems and methods for conducted communication are described. In one embodiment, a method of communicating with a medical device implanted within a patient comprises receiving, at a medical device via electrodes connected to the patient, a conducted communication signal, wherein the conducted communication signal comprises a signal component and a noise component. The method may further comprise adjusting, by the medical device, a receive threshold based at least in part on an amplitude of the received conducted communication signal so as to reduce an amplitude of the noise component of the conducted communication signal.

摘要： The present invention provides a novel design for sheaths intended for medical procedures. The sheath includes structures that anchor the sheath in a cavity or space when deployed but are at the same time retractable such that the sheath can be removed without tearing the tissue defining the space.

摘要： In some examples, a leadless pacing device (LPD) is configured to switch from a sensing without pacing mode to ventricular pacing mode in response to determining that no intrinsic ventricular activity was detected within a ventricular event detection window for at least one cardiac cycle, which may be referred to as loss of conduction. The ventricular pacing mode may be selected based on whether atrial oversensing is detected in combination with the loss of conduction. In some examples, an atrio-ventricular synchronous pacing mode is selected in response to detecting loss of conduction and in response to determining that atrial oversensing is not detected. In addition, in some examples, an asynchronous ventricular pacing mode is selected in response to detecting both atrial oversensing and loss of conduction.

摘要： Systems and methods for treating gastroesophageal reflux disease (GERD) includes minimally invasively implanting a stimulating device in a patient's esophagus in the region proximate the lower esophageal sphincter (LES). The patient is provided with a questionnaire related to his disease via an online service. The questionnaire is accessed on a mobile device, such as a cell phone, or on a computer with network access. The data from the sensors and the answers from the questionnaire are analysed together by a health care provider using the online service. The data and answers are used to program the stimulating device, via the mobile device or computer, to optimize treatment.

摘要： A system and method for treating anorectal and/or genitourinary dysfunction includes implanting, in a minimally invasive manner, an electro-medical device for stimulation of two or more anatomical or histological structures of the anorectal region and/or genitourinary region. Electrodes operably connected to the device are positioned proximate the target anatomical or histological structures. The device provides either the same or different stimulation algorithms to each anatomical or histological structure, which may be the same or different. The varied stimulation parameters, such as pulse width, pulse amplitude, and pulse frequency, are defined such that after an application of the electrical pulses, an abdominal leak pressure, an abdominal leak volume, or a urine volume increases or a number of incontinent episodes or a mean incontinence volume per episode decreases relative to said parameters prior to the application of the electrical pulses.
