  • INTRODUCER SHEATH FOR VASCULAR ACCESS
    Publication number: 20190298974
    Abstract: An introducer sheath for providing vascular access in a patient's body comprises a tubular body having a proximal end and a distal end, the distal end being configured to be inserted into a patient's vessel to allow a medical device to be inserted from the proximal end through the tubular body out of the distal end into the patient's vessel. The tubular body includes a recoil section that has a radial compressibility which is higher than a radial compressibility of at least a portion of the tubular body that is distal to the recoil section. This enables the patient's vessel and surrounding tissue to recoil at the puncture site, which is advantageous for the patient, e.g. with respect to wound healing.

  • BLOOD PUMP ASSEMBLY HAVING A SENSOR AND A SENSOR SHIELD
    Publication number: 20190282744
    Abstract: A blood pump assembly can include various components such as a housing and a sensor configured to detect one or more characteristics of the blood. In some embodiments, the sensor can be coupled to the housing and can include a sensor membrane configured to deflect in response to a change in a blood parameter (e.g., pressure). The blood pump assembly can include a shield that covers at least a portion of the sensor membrane so as to protect the sensor from damage when the blood pump assembly is inserted through an introducer and navigated through the patient's vasculature and/or when the blood pump assembly is inserted into the heart in a surgical procedure. One or more protective layers can be deposited over the sensor membrane to prevent the sensor membrane from being dissolved through interactions with the patient's blood.
