In various embodiments, the present invention provides a plurality of novel interspinous distraction devices and associated methods of insertion. The interspinous distraction devices of the present invention are designed and configured to effectively treat such conditions as lumbar spinal stenosis and degenerative disc disease. Advantageously, the interspinous distraction devices of the present invention may be inserted through conventional open procedures, typically requiring a relatively large incision and a general anesthetic, or through novel minimally-invasive procedures, typically requiring only a local anesthetic. These novel minimally-invasive procedures and related enabling devices are also disclosed and described herein.

Devices for efficient severing or cutting of a material or substance such as soft tissue suitable for use in open surgical and/or minimally invasive procedures are disclosed. A cutting assembly generally includes a first and second cutting blades each having an inner surface and at least one set of cutting teeth, the first inner surface being in contact with the second inner surface so that the sets of cutting teeth of the first and second cutting blades are aligned with and configured to cooperate with each other when at least one of the cutting blades moves, e.g., rotates and/or oscillates, relative to the other. A tissue cutting device generally includes a probe and the cutting assembly configured to be in a storage configuration or in a cutting configuration. The cutting assembly may provide a coagulation mechanism.

An implantable device system for controlling the dimensions of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implantable devices are disclosed which employ various mechanisms for adjusting and maintaining the size of an orifice to which they are attached. Systems permit the implants to be implanted using minimally invasive procedures and permit final adjustments to the dimensions of the implants after the resumption of normal flow of anatomic fluids in situ.

A spinal stabilization system may be formed in a patient. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient. Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. The collar may be rotated and/or angulated relative to the bone fastener. Extenders may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The extenders may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars. A reducer may be used to achieve reduction of one or more vertebral bodies coupled to a spinal stabilization system.

A bone graft needle, particularly useful in minimally invasive procedures, is provided. The bone graft needle as well as its corresponding penetrating member may be made from bendable materials so that the combined instrument can more easily access hard to reach areas of the body.

An implant for positioning between the spinous processes of cervical vertebrae include first and second wings for lateral positioning and a spacer located between the adjacent spinous processes. The implant can be positioned using minimally invasive procedures without modifying the bone or severing ligaments. The implant is shaped in accordance with the anatomy of the spine.

A noninvasive or minimally invasive procedure and system for measuring blood glucose levels is disclosed. A set of photodiodes detects the fluorescence and reflectance of light energy emitted from one or more emitters, such as LEDs, into a patient's skin. In an embodiment, small molecule metabolite reporters (SMMRs) that bind to glucose are introduced to the measurement area to provide more easily detected fluorescence.

A system for implanting a surgical device to control the circumference of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implants are disclosed which employ various means for adjusting and maintaining the size of an orifice to which they are attached.

A device for occluding a hollow anatomical structure includes a clamp having at least first and second clamping portions adapted to be placed on opposite sides of the anatomical structure. At least one of the first and second clamping portions is movable toward the other from an open position to a clamping or closed position to occlude the anatomical structure. The clamp has an annular shape configured to surround the hollow anatomical structure in the open position and a flattened shape in the clamping position configured to occlude the hollow interior of the anatomical structure. The clamp is preferably covered with fabric to promote tissue ingrowth. A clamp delivery and actuation device is provided for allowing the clamp to be applied in either an open surgical procedure or a minimally invasive procedure.

An implantable therapy delivery system has a therapy delivery element that is inserted or implanted into a human body and anchored or fixed to tissue to delivery a therapy to a patient. In one embodiment an implantable neurostimulator uses an electrical stimulation lead to delivery a therapy such as sacral nerve stimulation, peripheral nerve stimulation, and the like. In another embodiment the implantable therapeutic substance delivery device, also known as a drug pump, is connected to a catheter to deliver a therapy to treat conditions such as spasticity, cancer, pain, and the like. The therapy delivery element is anchored to tissue using an adjustable anchor having a therapy grip element, at least two extension elements connected to the therapy grip element, and a tissue fixation element connected to the extension elements. The extensions project substantially perpendicular in relation to the therapy delivery element and are configured to actuate the therapy grip element to an opened position and a closed position. A tissue fixation element is connected to the extensions and configured for fixation to a tissue location from an axial direction to the therapy delivery element. The adjustable anchor facilitates minimally invasive procedures, facilitates securing the therapy delivery element in the same plane as the therapy delivery element was inserted, facilitates rapid placement to reduce procedure time, and provides a wide range of other benefits. The adjustable anchor and its methods of operation have many embodiments.

A bone fusion method, system and device for insertion between bones that are to be fused together in order to replace degenerated discs and/or bones, for example, the vertebrae of a spinal column.
