  • Publication number: 20230110568
    Abstract: In one aspect, recording instruments, probes, probe sheaths, and probe sleeves may include one or more recording elements, such as one or more ECG wires, EEG wires, and/or SEEG wires. A recording element may be used for lesion localization and assessment at the time of cryotherapy, thermal therapy, or temperature modulation therapy. A recording element may be used to provide positioning and monitoring during functional neurosurgery; to apply local tissue stimulation responsive to detection of an abnormal event to regulate cellular behaviors during treatment; to effect deep brain stimulation during a neurosurgical operation; to monitor internal electrical signals and identify abnormalities. Recording instruments may be deployed in vivo for hours or days while monitoring and analyzing signals. For signal analysis, leads disposed between recording element contact surfaces and along a shaft of the recording instrument may deliver recorded signals to a controller external to the patient for analysis.

  • Patent number: 11484400
    Abstract: Embodiments of the present invention provide medical devices and methods for treating a target site within the body. For example, one embodiment provides a stent graft for treating a target site proximate to a bifurcated lumen, wherein the stent graft includes a first tubular structure having proximal and distal ends and a side wall extending therebetween. The first tubular structure includes an opening defined within the side wall and is configured to define a first portion having first and second ends and a second portion having first and second ends. The opening corresponds to the first ends of the first and second portions and the second ends of the first and second portions respectively correspond to the proximal and distal ends of the first tubular structure, and at least a portion of the first and second portions are configured to be positioned within respective branches of a bifurcated lumen.

    Abstract: One exemplary device includes a tubular structure having proximal and distal ends and at least one layer of braided material configured to facilitate thrombosis. The tubular structure includes an end section at the proximal or distal end having a cross-sectional dimension that is larger than that of an opening of the target site. The device also includes a stiffener wire coupled to the tubular structure, and the wire is configured to extend at least partially through the opening and facilitate securing the end section over the opening. The tubular structure and stiffener wire include respective preset, expanded configurations and are configured to be constrained to respective reduced configurations for delivery to the target site and to at least partially return to their respective preset, expanded configurations at the target site when unconstrained.

  • Patent number: 10675113
    Abstract: In an embodiment, a method for effecting thermal therapy using an in vivo probe includes positioning the probe in a volume in a patient, identifying an irregularly shaped three-dimensional region of interest and automatically applying thermal therapy to the region using the probe. Applying thermal therapy may include identifying a first emission level at a first rotational angle based in part on a depth of a radial portion of the region in the direction of probe emission, activating emission of the probe, causing rotation of the probe to a next rotational angle, identifying a next emission level at the next rotational angle based in part on a depth of a radial portion of the region in the direction of probe emission, activating emission to deliver therapeutic energy, and repeating rotation and emission until therapeutic energy has been delivered to the volume.

  • Patent number: 10660737
    Abstract: An intravascular medical device including an elongated member configured to be advanced along a vascular path of a patient, the elongated member having opposite first and second ends, the first end and second ends both being adapted for intravascular insertion, and the first end having a different structure than the second end. The elongated member has sufficient flexibility to be advanced through a human vasculature. Preferably, the first and second ends are adapted to have different operating characteristics. Depending on the operating characteristics needed for a particular procedure, a physician can insert either the first end portion or the second end portion of the elongated member into the patient's vasculature.

  • Patent number: 10342632
    Abstract: In one aspect, the present disclosure relates to a head fixation apparatus including a number of support posts, and a curved ring portion including a number of connectors configured to adjustably and releasably mount support posts on the lower ring portion, such that the support posts are selectively mounted to a subset of the connectors in a customized arrangement for a patient. The apparatus may include a ring mount configured for fixation to a platform, including a curved channel substantially matching a curvature of the curved ring portion, and a mount locking mechanism for locking the curved ring portion within the channel of the ring mount. The curved ring portion may be configured to rotate within the channel of the ring mount while the ring mount is fixed to the platform, an angular head position of the patient being selectably adjustable while the patient is laying on the platform.

  • Patent number: 10327830
    Abstract: A variable length interstitial probe apparatus includes: a probe for effecting thermal therapy and/or cryotherapy to a tissue; a flexible umbilical sheath permanently affixed to the probe, including at least one interface for supplying energy, cooling fluid, cooling gas, heating fluid, and/or heating gas to the probe; and an adjustable depth stop configured to slide along a length of a shaft region of the probe, and lock to the shaft region at a selected position. The adjustable depth stop is configured to engage a probe driver and/or a skull mount apparatus to stabilize positioning of the probe and to control a depth of entry of the probe into a patient. The probe may be configured to effect temperature modulation therapy, where processing circuitry activates a modulation pattern of thermal therapy emission and cryogenic therapy emission for applying a thermal dose to the tissue.

  • Patent number: 9968433
    Abstract: An embolic protection device includes an outer surface that is configured to form a substantially sealed relationship with a body lumen such that emboli are deflected and/or captured by the outer surface before such emboli can travel to other parts of the body. An inner surface of the embolic protection device includes a longitudinally extending lumen through which instrumentation may be inserted, facilitating passage of such instrumentation through the body lumen while minimizing risk to the patient from emboli.
