    Abstract: Described herein are devices, systems and methods for cutting tissue in a patient. In some embodiments, a tissue modification region of a device includes a pair of flexible elongate cutting members extending along the length of the tissue modification region. Each elongate cutting member may be configured to cut a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. In some embodiments, the device includes a spacer. The spacer may be sized and configured to operate in one of two modes. A first mode, in which the spacer is coupled to the cutting members such that it holds a portion of each of the two cutting members a distance from one another, and a second mode, in which at least a portion of the spacer is moved away from a cutting member to allow the cutting members to cut further into tissue.

    Abstract: A catheter section comprising an elongate tubular member having a proximal end, a distal end, and a passageway defining a lumen extending between the proximal and distal ends. The elongate tubular member includes a knit tubular member and an inner tubular liner in coaxial relationship with the knit tubular member. The catheter section is for use as a distal section in a catheter having a relatively stiff proximal section.

    Abstract: An apparatus for delivering electrical energy includes a cannula and one or more needles extendable from and retractable into a lumen of the cannula. A distal portion of each needle is extendable from the lumen and terminates in a tissue-piercing distal tip. Each distal portion is formed from an electrically conductive and porous material, thereby providing a porous electrode through which electrolytic fluid may flow for delivering electrical energy to tissue surrounding the distal portion. The cannula is introduced into a tissue structure of a patient, the one or more needles are advanced from the cannula, saline is introduced from the porous material to surrounding tissue, and electrical energy from an RF generator is delivered to ablate tissue within the tissue structure.

    Abstract: A medical assembly and method are provided to effectively treat abnormal tissue, such as, a tumor. The target tissue is thermally ablated using a suitable source, such as RF or laser energy. A cooling shield is placed in contact with non-target tissue adjacent the target tissue, and actively cooled to conduct thermal energy away from the non-target tissue. In one method, the cooling shield can be placed between two organs, in which case, one of the two organs can comprise the target tissue, and the other of the two organs can comprise the non-target tissue. In this case, the cooling shield may comprise an actively cooled inflatable balloon, which can be disposed between the two organs when deflated, and then inflated. The inflatable balloon can be actively cooled by pumping a cooling medium through it. In another method, the cooling shield can be embedded within the non-target tissue. In this case, the cooling shield can comprise one or more needles. If a plurality of needles is used, they can be embedded into the non-target tissue in a series, e.g., a rectilinear or curvilinear arrangement. The needle(s) can be actively cooled by pumping a cooling medium through them.

    Abstract: A medical lead and method of treating a patient are provided. The medical lead comprises an electrically insulative tubular membrane, a resilient spring element associated with the insulative membrane, and at least one electrode associated with the insulative membrane. The medical lead is configured to be collapsed into a compact form for percutaneous delivery into the patient, thereby obviating the need to perform an invasive surgical procedure on the patient. The body formed by these elements, when expanded, can be sized to fit within the epidural space of a patient. The patient can be treated by placing the medical lead into a collapsed state by applying a compressive force to the medical lead, percutaneously delivering the collapsed medical lead into the patient adjacent tissue to be treated, and placing the medical lead into an expanded state by releasing the compressive force. In one preferred method, the stimulation lead is used to stimulate tissue, such as spinal cord tissue.
