  • Patent number: 10111651
    Abstract: A method of anchoring a support material to tissue includes forming an incision in a urogenital triangle of a patient for access to a pelvis of the patient; inserting a body portion of an anchor into a lumen in a cannula and having a spine portion of the anchor extending radially out of a wall of the cannula; and inserting a leading end of the cannula and the anchor into the incision. The method includes pushing the leading end of the cannula into periosteum tissue of the pelvis; engaging the spine portion of the anchor with the periosteum tissue; withdrawing the leading end of the cannula from the incision and leaving the anchor engaged in the periosteum tissue; and securing the support material to a suture that is attached to the anchor. The method includes delivering the support material through the incision to the pelvis.

  • Patent number: 10098771
    Abstract: A sheath is placed over a crimped scaffold to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath has an opening spanning the length of the sheath. The opening spans an arc length of about 90 degrees with respect to the circumference of the scaffold or balloon. The sheath may be removed from the scaffold by pinching the sheath between a thumb and forefinger, or bending or peeling back the sheath from the edges of the opening using fingertips.

  • Patent number: 10035014
    Abstract: An implantable medical lead has a torsional stiffness and is rotationally coupled to a stylet. Applying rotation directly to the lead in turn causes rotation of the stylet. Where the stylet has a bent tip for purposes of steering the lead, the rotation applied to the lead rotates the bent tip so that the lead can be steered by rotating the lead rather than rotating a hub of the stylet. The rotational coupling may be achieved through one or more features provided for the lead and/or the stylet, such as a feature within a lumen of the lead that mates to a feature along the stylet or a feature of the stylet hub that engages the proximal end of the lead. The torsional stiffness of the lead may be provided by adding a feature within the lead body, such as a braided metal wire or an overlapping foil.

  • Patent number: 9955992
    Abstract: The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.
