    Abstract: A self-dilating cannula for introduction into a patient's vasculature includes an elongate body and an atraumatic tip. The elongate body has a proximal end, a distal end, and a fluid-flow lumen extending therebetween. The atraumatic tip is positioned at the elongate body's distal end and has a blunted end and a conical shape. The atraumatic tip includes a plurality of fluid-flow openings proximal to the blunted nose that are configured to disperse fluid from the fluid-flow lumen in a plurality of directions with respect to the atraumatic tip. The atraumatic tip also includes an opening in the blunted nose that is sized to a guidewire.

    Abstract: Access devices (10) and related methods are disclosed that generally involve flexible or adjustable cannulas (14) that have a substantially cylindrical insertion configuration and a substantially conical expanded configuration. Various methods and features are provided for transitioning the cannula from the insertion configuration to the expanded configuration while the access device is inserted through tissue to form a conical opening through the tissue. Examples include cables (15), biasing elements (120), retaining elements (122), bimodal rings (152), and coil springs (219). The devices and methods disclosed herein can allow for improved retention of the access device, improved angulation of instruments passed through the access device, and can increase the integrity of a seal formed between the access device and surrounding tissue.

    Abstract: Methods and devices are provided to allow the same component used to access a surgical site to assist in closing the surgical opening in which it was disposed. In one exemplary embodiment a flexible retractor (20) is provided that includes proximal and distal ends and a lumen extending therethrough. A wound closure component (140) is associated with the flexible retractor and is configured to engage tissue adjacent to a surgical incision in which the retractor is disposed and move tissue from one side of the surgical incision toward a second side of the surgical incision to assist in closing the surgical incision. In one embodiment the wound closure component includes strands of suture (42) having hooks (44) disposed on a distal end. In another embodiment the wound closure component includes a ring having hooks disposed around a circumference of the ring. Exemplary methods for closing a surgical opening are also provided.
