摘要:
Devices and methods are provided for penetrating tissue and/or effecting movement of devices relative to tissue. In general, a surgical instrument is provided having an at least partially fabric-covered distal tip that be used to at least partially penetrate tissue by contacting the tissue with the fabric and rotating the fabric to “drill” into the tissue. The surgical instrument can be configured for delivery proximate to tissue through a working channel of a delivery device and can include an elongate shaft having in its distal portion an end effector at least partially covered in fabric. The fabric, the end effector, and/or the shaft can rotate, thereby allowing at least the fabric to penetrate the tissue and, if sufficiently rotated, causing an opening to form in the tissue. The surgical instrument and/or the delivery device can be advanced through the opening.
