  • Publication number: 20140276983
    Abstract: A suturing device includes a handle, an elongated body, at least one suture snag, at least one pair of needles, and at least one suture pair. The suture snag is moveable between a deployed position in which two distal arm portions thereof radially extend away from the elongated body and a retracted position in which the two distal arm portions are disposed within the elongated body. The suture pair is slidingly disposed through the needle pair. The suturing device deploys the suture snag within a vessel adjacent to an arteriotomy, extends the needle pair through a vessel wall around the arteriotomy and through the deployed suture snag, extends the suture pair beyond the distal ends of the needle pair, and then utilizes the suture snag to capture the extended suture pair by retracting the suture snag to pull first or distal ends of the sutures back into the suturing device. An inflatable balloon or an expandable suture capture component may be alternatives to the suture snag for capturing the suture ends.

  • Publication number: 20140277251
    Abstract: In general, the disclosure is directed to an implantable neurostimulator and system capable of providing adaptive neurostimulation therapy to alleviate incontinence. The neurostimulator operates according to a set of stimulation parameters stored in memory. During operation, information is obtained from the patient, the implanted neurostimulator, one or more implanted sensors, or some combination thereof. A processor analyzes the information to automatically generate proposed adjustments to the stimulation parameters applied by the neurostimulator. The adjustments provide an adaptive neurostimulation therapy that supports or enhances therapeutic efficacy based on the information.

  • Publication number: 20140277246
    Abstract: The present disclosure pertains to cardiac pacing methods and systems, and, more particularly, to cardiac resynchronization therapy (CRT). In particular, the present disclosure pertains to determining whether a patient is experiencing atrial fibrillation (AF). If the patient is experiencing AF, the efficacy of CRT is determined. A signal is sensed in response to a ventricular pacing stimulus. Through signal processing, a number of features are parsed from the signal and a determination is made as to whether the ventricular pacing stimulus evoked a response from the ventricle.

  • Publication number: 20140277250
    Abstract: In some examples, relatively low frequency (e.g., less than about 50 Hertz) electrical stimulation therapy is delivered to a target tissue site proximate to one or more of the T9, T10, T11, T12, L1, L2, or L3 (“T9-L3”) spinal nerves of a patient to manage a pelvic floor disorder, such as urinary retention, fecal retention, or both. The relatively low frequency electrical stimulation therapy is configured to excite the one or more of the T9-L3 spinal nerves, which may generate an activating response from the patient related to voiding and help promote voiding by the patient. For example, the low frequency electrical stimulation may be configured to help improve the patient's pelvic sensations, which may help the patient better control urination.

  • Patent number: 8834392
    Abstract: Techniques relate to operating a medical device in response to a detected posture state of a patient. A trigger event such as a request to modify how therapy is being delivered to the patient may cause a determination to be made as to whether the patient's posture state is stable. If the posture state is stable, an association is created between the posture state and one or more therapy parameter values. Over time, a library of such associations is created that may reflect any posture state in three dimensional space, wherein a posture state comprises at least one of a posture and an activity component. The library of associations may be used to automatically control therapy delivery. Similar ones of the associations may automatically be grouped into posture state regions to facilitate more efficient classification of the patient's posture state to control therapy delivery.
