摘要:
A medical monitoring device for monitoring electrical signals from the body of a subject is described. The medical monitoring device monitors electrical signals originating from a cardiac cycle of the subject and associates each cardiac cycle with a time index. The medical monitoring device applies a forward computational procedure to generate a risk score indicative of hyperkalemia, hypokalemia or arrhythmia of the subject. The medical monitoring device can adjust the forward computational procedure based upon clinical data obtained from the subject.

摘要:
An implantable medical elongated member extends between a proximal end configured to be coupled to a medical device and a distal end. The implantable elongated member includes one or more fixation elements coupled to at least a middle portion and/or a proximal portion of the elongated member in order to substantially fix a position of the elongated member to tissue at one or more intermediate points between the proximal end and the distal end of the elongated member.

Described are implantable devices and methods for treating various disorders of the pelvic floor by means of electrical stimulation of tissue volumes at two or more locations adjacent sacral nerves or portions thereof, and/or pudendal nerves or portions thereof. Two or more electrical stimulation regimes are applied on a continuous, alternating, intermittent or other basis to the respective tissue volumes in an amount and manner effective to treat a number of disorders, including, but not limited to, urinary and/or fecal voiding dysfunctions such as constipation, incontinence disorders such as urge frequency and urinary retention disorders, sexual dysfunctions such as orgasmic and erectile dysfunction, pelvic pain, prostatitis, prostatalgia and prostatodynia.
摘要:
A regeneration system that has a first regeneration module containing a first chosen regenerative substance; a second regeneration module containing the first chosen regenerative substance; and a first mixing chamber. A first outlet stream of a fluid sequentially exits the first mixing chamber, flows through the first regeneration module in fluid communication with the first chosen regenerative substance and returns to the first mixing chamber, and a second outlet stream of the fluid sequentially exits the first mixing chamber and flows through the second regeneration module in fluid communication with the first chosen regenerative substance.

摘要:
Systems and methods for controlling fluid movement and volumes of fluid between a subject and a controlled compliant flow path. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the controlled compliant flow path. An extracorporeal flow path is in fluid communication with the controlled compliant flow path across a semi-permeable membrane where the extracorporeal flow path has a first terminal end and a second terminal end.
摘要:
Techniques for controlling therapy delivery based on the relative orientation and/or motion of a device accelerometer and a lead accelerometer are described. In one embodiment, a therapy system includes an electrical stimulator and a lead. The electrical stimulator comprises a processor that controls delivery of a therapy to a target stimulation site in a patient and a device accelerometer coupled to the electrical stimulator. The lead is coupled to the electrical stimulator to deliver the therapy from the electrical stimulator to the target stimulation site in the patient, and includes a lead accelerometer. The processor compares signals from the accelerometers, and controls delivery of the therapy to the patient based on the comparison. In this manner, the processor may adjust stimulation to, for example, address movement of electrodes relative to target tissue when a patient changes postures.

Systems and methods for managing the pH of a dialysate fluid during hemodialysis therapy. The systems and methods adjust dialysate pH and buffer concentration to generate a predetermined total bicarbonate buffer concentration in a dialysate entering a dialyzer.
摘要:
A therapy program may be generated based on an algorithmic model of a baseline therapy field, which may represent a therapy field resulting from therapy delivery via the first therapy system based on a first therapy program. A second therapy program that controls therapy delivery by a second therapy system may be generated based on the baseline therapy field model. For example, therapy parameter values of the second therapy program may be selected to maintain at least one field characteristic of the baseline therapy field model. In some examples, the second therapy system may result from a hardware modification to the first therapy system. In other examples, the first and second therapy systems may be associated with different patients. For example, the baseline therapy field model may be an efficacious therapy field for a patient class, and a second therapy program may be generated for a patient in the class.
