    摘要: An apparatus for accessing the epidural space in a mammal has a cutting sheath with a distal end adapted to transition from a closed cutting configuration to an open configuration. A tissue engagement device is in a hollow portion of the sheath. The tissue engagement device has a blunt distal end and an engagement feature. A method of accessing an epidural space includes the step of forming an opening to a position at or near the ligamentum flavum using the cutting sheath. Another step of the method is positioning a tissue engagement device within the hollow portion of the cutting sheath. Another step of the method is transitioning the cutting sheath from the closed cutting configuration to the open configuration. Another step of the method is manipulating the tissue engagement device to controllably advance the tissue engagement device at least partially through the ligamentum flavum.

    摘要: Provided are surgical fasteners coated with a material including an initiator configured for activation upon application of an initiator. The surgical fasteners may be configured for use in combination with a surgical fastener applying apparatus. In one version, the surgical fastener is a surgical staple including a pair of legs, a crown interconnecting the pair of legs, and a material including an initiator coating at least a portion of the legs and/or crown. Adhesive may be delivered into contact with the initiator associated with the surgical fasteners such that a desirable size, shape, and configuration of activated or polymerized adhesive is created.
