  • Patent number: 10639485
    Abstract: An operating-room cable-assembly for an electrical-stimulation system includes a lead connector with a lead passageway defined in a housing. Contacts disposed in the housing engage terminals of a lead when the lead is operationally-inserted into the lead passageway. A first biased tab is disposed in a first tab lumen defined in the housing. The first biased tab has a first end exposed to an outer surface of the housing and an opposing second end exposed to the lead passageway. The first biased tab moves to an unlock position and is biased to return to a lock position.

  • Patent number: 9364283
    Abstract: Devices and methods are provided for ablational treatment of regions of the digestive tract in post-bariatric surgery patients who fail to achieve or maintain the desired weight loss. Bariatric procedures include Roux-en-Y gastric bypass, biliopancreatic diversion, and sleeve gastrectomy. These procedures reconstruct gastrointestinal tract features, creating pouches, stoma, and tubes that restrict and/or divert the digestive flow. Post-surgical dilation of altered structures is common and diminishes their bariatric effectiveness. Ablation of compromised structures can reduce their size and compliance, restoring bariatric effectiveness. Ablation, as provided the invention, starts at the mucosa and penetrates deeper into the gastrointestinal wall in a controlled manner. Control may also be provided by a fractional ablation that ablates some tissue within a target region and leaves a portion substantially unaffected.

  • Patent number: 9095703
    Abstract: The present disclosure relates to permanently implantable electrode structures or probes of the type used, in particular, in cardiac pacemakers, ICDs, CRT-Ds and/or neurostimulators. Such electrode structures or probes include at least one control element, the physical-chemical state of which can be specifically manipulated using external excitation, such that local degradation or dissolution of a part of the implant or the entire implant takes place in this region. As a result of this partial dissolution, for example, the electrode structure or at least a portion thereof is modified such that the conditions for explantation are improved and/or parts of an implanted electrode structure that remain in the body are functionally deactivated.

  • Patent number: 8903514
    Abstract: A medical implantable lead comprises a conduction controlling means, which at least during an initial stage after implantation is capable of rendering a first contact surface electrically inactive and which is capable of rendering the first contact surface electrically active after the initial stage. By means of the inventive lead it is possible to detect whether the helix is sufficiently screwed into the tissue or not.

  • Patent number: 8801728
    Abstract: Leads having distal electrodes may be used in application of test stimulation for purposes of implanting a lead having a fixation element distal to an electrode array. The fixation element is proximal the distal electrode. Accordingly, the distal electrode may be advanced beyond a distal end of an introducer while the fixation element may be retained in a retracted configuration by the introducer. If the test signals applied by the distal electrode indicate that the distal electrode is in the desired location of the patient, a series of markings on the lead may be used to facilitate placement of the electrode array at the location previously occupied by the distal electrode; i.e. the desired location of the patient. The electrodes of the electrode array may then be used to provide therapy to the patient.

  • Patent number: 8801693
    Abstract: A system and method for guiding a catheter or other medical device to a desired target destination within the vasculature of a patient via bioimpedance measurements is disclosed. The target destination in one embodiment includes placement of the catheter such that a distal tip thereof is disposed proximate the heart, e.g., the junction of the right atrium and superior vena cava. In one embodiment the method for guiding the catheter comprises introducing the catheter into a vessel of the patient, the catheter defining a lumen through which fluids can be infused into the vasculature of the patient. The catheter is advanced toward a target destination within the vasculature. A first impedance value based on intravascular detection of at least one electrical property related to a first tissue surface of the vessel is calculated to enable determination of the proximity of a distal end of the catheter to the target destination.

  • Publication number: 20140148675
    Abstract: A detachable electrode and anchor utilized with electrode leads and leadless medical implants that enable explantation of the electrode while leaving the anchor in place. The detachable electrode and anchor utilizes a detachable mechanism that detachably couples the electrode to the anchor. Embodiments do not require removal of existing scar tissue before explantation, which minimize chances of internal bleeding at the extraction site. Embodiments also minimize impact on the vein in which the electrode lead travels by eliminating use of a necessarily larger diameter sheath that is utilized around the electrode lead to remove the electrode lead and attached anchor.
