  • Tissue-removing catheter including urging mechanism
    Patent number: 10874420
    Abstract: A tissue-removing catheter includes an elongate catheter body. The catheter body has a jogged portion that applies an urge force against a body lumen wall and urges a portion of the catheter body toward a portion of the body lumen wall. A tissue-removing element removes tissue from the body lumen during the cutting operation. The tissue-removing element is located generally adjacent the portion of the catheter body that is urged toward the body lumen wall by the logged portion. An urging mechanism selectively applies a compressive load to the catheter body to adjust the bending stiffness of the jogged portion and the urge force applied by the jogged portion.

  • Intrauterine balloon apparatus, system, and method for augmenting uterine birthing forces during parturition
    Patent number: 10856754
    Abstract: An intrauterine balloon apparatus to augment uterine birthing forces and assist fetal descent during parturition is provided. The body of the balloon apparatus begins packaged in a compressed state minimizing volume, enabling delivery through the birth canal. The apparatus is advanced to a proximal uterine location and deployed for operation by introducing a pressurized agent through its conduit, causing the body to expand and apply directional forces towards the infant and birth canal. The balloon body is shaped to apply pressures dispersed towards the infant and the bidirectional conduit enables fluid conduction as the infant descends. After the infant has successfully descended and been delivered through the birth canal, pressure within the balloon body is relieved through the conduit thereby collapsing the volume of the balloon body and enabling retraction through the birth canal.
