Abstract: A spinal catheter for insertion into the epidural space of a human or animal subject includes first and second lumens. A pressurized fluid can be discharged through the first lumen directly onto a tissue obstruction to form a partial/pilot or full/final opening in the tissue obstruction. If a full opening was not formed sufficient for passage of the stimulator lead, the distal-end portion of the stimulator lead can be inserted into the partial opening and then a pressurized fluid can be delivered through the second lumen and into a distensible balloon for expanding the balloon to clear the tissue obstruction sufficient for passage of the stimulator lead. In this way the catheter can be advanced past a tissue obstruction and into place for use within the epidural space, without having to remove and reinsert multiple surgical implements.

Abstract: A spinal cord stimulator lead for implanting into the epidural space of a human or animal subject includes first and second lumens and electrical contacts. A pressurized fluid can be discharged through the first lumen directly onto a tissue obstruction to form a partial/pilot or full/final opening in the tissue obstruction. If a full opening was not formed sufficient for passage of the stimulator lead, the distal-end portion of the stimulator lead can be inserted into the partial opening and then a pressurized fluid can be delivered through the second lumen and into a distensible balloon for expanding the balloon to clear the tissue obstruction sufficient for passage of the stimulator lead. In this way the stimulator lead can be advanced past a tissue obstruction and into place for use to deliver therapeutic energy to spinal tissue adjacent the contacts, without having to remove and reinsert multiple surgical implements.

Abstract: A method of implanting a spinal cord stimulator lead in the epidural space of a human or animal subject. The method includes expanding a distensible balloon, which is positioned around a distal end of the shaft and in fluid communication with a lumen, to clear a tissue obstruction during the implantation. Preferably, the balloon expands radially outwardly from at least a portion of the shaft's distal end. The method can also include discharging a pressurized fluid, axially through a lumen in the spinal cord stimulator lead, directly to a tissue obstruction during the implantation.

Abstract: An anchor for a spinal cord stimulator lead or an intrathecal catheter lead includes a gripper for securely gripping the lead and a suture ring for suturing the anchor to the adjacent tissue.

Abstract: A spinel cord stimulator lead for placement in the epidural space of a human or animal subject. The spinal cord stimulator lead includes a biocompatible body portion defining an elongate shaft, wherein at least a portion of which is flexible; at least one electrode positioned along the shaft; a lumen extending through at least a portion of the shaft for carrying a fluid; and a distensible balloon positioned around a distal end of the shaft and in fluid communication with the lumen. Preferably, the balloon is a cuffed balloon that expands radially outwardly from at least a portion of the shaft's distal end. The spinal cord stimulator lead can also include a second lumen for discharging a fluid directly to a tissue obstruction and a stylet for guiding the stimulator lead into and through the epidural space. The spinal cord stimulator lead can have the form of a percutaneous lead or a surgical lead.

Abstract: A percutaneous lead with at least one electrode has a lumen or fluid canal extending the length of its biocompatible body. The lumen aids in accurately placing the percutaneous lead by allowing a practitioner to inject fluid, such as a saline solution, through the canal to displace fat, veins, adhesions, or connective tissues that prevent the passage or accurate placement of the lead in the epidural space. Optionally, an inflatable balloon is attached at the distal end of the percutaneous lead to further aid in displacing connective tissue.
