Abstract: A knotless anchor for attachment of tissue to bone includes a rigid anchor body and a suture extending there from. The suture is hollow and includes a fixed limb portion secured to the rigid anchor body. A soft suture tunnel extends in a longitudinal direction through the fixed limb portion of the suture. A free suture limb is passed through the tissue, back to the anchor, and through the soft suture tunnel, thereby creating a closable suture loop around the tissue. Tension applied to the free suture limb closes the suture loop, and approximates the tissue to the anchor body. When the anchor is deployed in a bone hole, external features of the anchor body grip the walls of the bone hole and simultaneously compress the suture, thereby preventing tissue pull-out. Anchor assemblies and methods of tissue fixation are also disclosed.

Abstract: An expandable tissue dilator for dilating tissue around a spinal column includes a housing and a shaft at least partially positioned distally of the housing and adapted to pierce a tissue around the spinal column. An expandable member attached to the housing expands around a portion of the shaft to dilate the pierced tissue in a single-pass dilation resulting in a reduction of any traumatic impingement of nerves or muscle tissue and reduction in procedure time.

Abstract: Tortuosity of vessels at or leading to the site of minimally invasive procedures is a problem for conducting such procedures as they increase the difficulty to guide the procedural catheters through tortuous vessels.

The apparatus and method for improving access include application of a pull component to the stabilized procedural catheter using a stabilization catheter/wire in addition to a push component from the percutaneous access to make the access easier while enabling use of more flexible catheters and softer wires. These methods and devices address the problems of trauma to the vessels during access, procedure and removal of catheters and wires, improve pushability of softer catheters and wires, and also substantially reduce substantially the procedure time.
