  • Publication number: 20220192681
    Abstract: An adaptor assembly for coupling a cutting tool to a drill drive chuck such that driven rotation of the drive chuck is transferred to the cutting tool by the adaptor assembly. The adaptor assembly includes a rod, a collet and an enclosure. A proximal region of the rod provides an adaptor male coupling portion configured to engage a drill drive chuck. A leading of the collet provides an adaptor female coupling portion configured to engage a surgical cutting tool tang. Further, the rod and the collet form complementary engagement features for coupling to one another. The enclosure rotatably maintains the collet. Upon final assembly of the rod to the collet, rotation of the rod is transferred to the collet. During use, the adaptor assembly can facilitate coupling of a cutting tool to a powered handpiece under circumstances where the cutting tool is otherwise incompatible with the powered handpiece.

  • Patent number: 11364072
    Abstract: Methods, systems, and devices for enhancing the efficiency and efficacy of energy delivery and tissue mapping. One system includes a treatment element having a plurality of electrodes and an energy generator that is configured to deliver electric energy pulses to the electrodes in a variety of patterns. For example, electrodes may be arranged in closely spaced pairs. The energy generator may deliver mapping energy to each electrode in each pair individually to map tissue and may deliver ablation energy to the electrodes in each pair together, such that each pair is treated like a single electrode, to deliver ablation energy, such as bipolar ablation energy between adjacent pairs. One system includes at least one concave electrode, the configuration of which concentrates the energy and drives it deeper into the tissue. One system includes neutral electrodes between active electrodes, the energy generator selectively coupling the neutral electrodes to alter the ablation pattern.

  • Patent number: 11359050
    Abstract: A method for preparing tyrosine derived polyarylates includes combining a desaminotyrosyl-tyrosine ethyl ester, a desaminotyrosyl-tyrosine benzylester, succinic acid and a catalyst in a flask to produce a first mixture. Methylene chloride is added to the first mixture to produce a first suspension. Diisopropylcarbodiimide (DIPC) is added to the first mixture to produce a first solution. The first solution is added to a non-solvent to produce a precipitate. The precipitate is dissolved in methylene chloride to form a polymer solution. The polymer solution is blended with a slurry to produce polymer shreds. The polymer shreds are blended with a second slurry to produce a tyrosine derived polyarylate.

  • Patent number: 11357988
    Abstract: An implantable medical device performs a method that includes detecting a cardiac event interval that is greater than a P-wave oversensing threshold interval. In response to detecting the cardiac event interval greater than the P-wave oversensing threshold interval, the device determines the amplitude of the sensed cardiac signal and withholds restarting a pacing interval in response to the amplitude satisfying P-wave oversensing criteria. A pacing pulse may be generated in response to the pacing interval expiring without sensing an intrinsic cardiac electrical event that is not detected as a P-wave oversensing event.

    Abstract: A medical lead includes a lead body, an electrical connector, an electrical conductor, and a sleeve. The lead body includes a distal end and a proximal end defining a longitudinal axis of the lead body. The electrical connector is positioned near the proximal end of the lead body. The electrical conductor extends about the longitudinal axis of the lead body. The sleeve is coupled to an insulative material of the lead body and positioned around the electrical conductor. The electrical conductor is electrically coupled to the electrical connector. The sleeve is not fixed to the electrical conductor. In response to bending of the medical lead, the conductor may move within the sleeve to relieve strain created by the bending.

  • Patent number: 11357484
    Abstract: An improved assembly for securing an implantable medical device for retrieval from an implant site includes a plurality of snares, wherein distal openings of a first snare carrier lumen and a second snare carrier lumen have a pre-set offset established therebetween. First and second snare shafts, to which first and second snare loops are coupled, respectively, extend within the corresponding snare carrier lumens such that each loop is located in proximity to the corresponding distal opening of the lumen. The pre-set offset allows an operator to simultaneously position the snare loops around the device; and, when the operator retracts the snare shafts to collapse the snare loops until the loops fit snuggly around the device, the pre-set offset can help to align the device for retrieval.

  • Patent number: 11351382
    Abstract: The disclosure describes an enhancement to lead monitoring techniques, which uses a sensing integrity counter (SIC). The techniques of this disclosure may enhance lead monitoring techniques by detecting possible sensing issues based on a significant increase in periodic, e.g., daily, SIC counts relative to previous periods. Some issues with sensing cardiac signals via implantable cardiac leads can result in an implantable medical device (IMD) measuring very short intervals between what appears to be sensed heart beats. Examples of issues include insulation breach, conductor fracture, or poor electrical connection, which may cause noise that appears to be an R-wave. The IMD may detect the noise, along with actual R-waves, and determine that there are relatively short (e.g., less than a threshold) intervals between the “R-waves.” A significant increase in the number or frequency of very short intervals between R-waves may indicate the date/time of a significant sensing issue.

  • Patent number: 11351383
    Abstract: A method and implantable medical device system for delivering a left ventricular (LV) cardiac pacing therapy via a single-pass coronary sinus lead and sensing far-field cardiac signals via one or more far-field sensing vectors formed between the plurality of electrodes. Beat morphologies corresponding to the far-field cardiac signals are determined, and a beat morphology match between each of the far-field beat morphologies and an intrinsic beat morphology template is determined so that one of loss of LV capture, pseudo fusion and loss of synchrony is determined in response to the determined beat morphology match. One of a loss of capture adjustment, a pseudo fusion adjustment, and a resynchronization adjustment is performed in response to the determined one of loss of LV capture, pseudo fusion and loss of synchrony in response to the determined beat morphology match to generate an adjusted LV cardiac pacing therapy.

  • Patent number: 11355244
    Abstract: Techniques that include applying machine learning models to episode data, including a cardiac electrogram, stored by a medical device are disclosed. In some examples, based on the application of one or more machine learning models to the episode data, processing circuitry derives, for each of a plurality of arrhythmia type classifications, class activation data indicating varying likelihoods of the classification over a period of time associated with the episode. The processing circuitry may display a graph of the varying likelihoods of the arrhythmia type classifications over the period of time. In some examples, processing circuitry may use arrhythmia type likelihoods and depolarization likelihoods to identify depolarizations, e.g., QRS complexes, during the episode.

  • Patent number: 11344735
    Abstract: Medical devices include a separate enclosure that houses a battery and electrically isolates the battery from external conditions such as any metal enclosures and ultimately isolates the battery from body fluids. Thus, the separate enclosure attaches to a housing of a medical device and provides for modularity of the battery which allows, for instance, different size batteries to be used with the same medical device design. The separate enclosure further prevents stimulation current from leaking back to the battery housing by providing the electrical isolation.
