In some examples, a tool for, e.g., creating a sub-sternal tunnel in a patient or other use, is described. The tool may include a handle and a tunneling shaft coupled to the handle. The tunneling shaft extends from a proximal end to a distal end, and at least a portion of the tunneling shaft extends in a curved orientation between the first end to the distal end. The distal end of the tunneling shaft includes a cutting tool having a sharp edge. The cutting tool is moveable from a recessed position in which the sharp edge of the cutting tool is recessed into the distal end of the tunneling shaft to a deployed position in which the sharp edge of the cutting tool extends beyond the distal end of the tunneling shaft in the deployed position, e.g., to cut pericardium, scar tissue, and/or connective tissue with the sharp edge.

A coracoid drill guide assembly includes a body having a cylindrical channel on each side of the body for receiving a drill guide sleeve. The sleeves of the assembly have a 1.4 mm inner diameter to guide a 1.3 mm (or smaller) K-wire through the sleeve. An aimer arm extends from the body at a non-intersecting angle with the drill sleeve. The assembly also has a self-locking ratchet mechanism to lock the sleeve in place once the assembly has been secured to bone.

A method of recanalizing a lumen of a vessel includes positioning an ultrasonic device having a distal end in a first position within the lumen of the vessel; transmitting pulsed ultrasonic vibrations though the ultrasonic device to the distal end; and advancing the distal end through the lumen to recanalize the vessel.

A system for subcutaneously injecting and anchoring a subcutaneous device to a muscle, a bone, and/or a first tissue of a patient, the subcutaneous device including a housing and a clip configured to anchor the subcutaneous device to the muscle, the bone, and/or the first tissue, includes a first surgical instrument and an insertion device. The first surgical instrument includes a first handle and a first dilation portion extending from the first handle. The first dilation portion has a first length and a first width and is configured to spread a second tissue through which the subcutaneous device is to be inserted. The insertion device is configured for insertion through the second tissue spread by the first surgical instrument. The insertion device includes an insertion handle and an insertion portion extending from the insertion handle and being configured to releasably hold the subcutaneous device to implant the subcutaneous device for anchoring to the muscle, the bone, and/or the first tissue.

A method of subcutaneously injecting and anchoring a device to a bone, a muscle, and/or a first tissue in a patient, the device having a clip configured to anchor the device to the bone, the muscle, or the first tissue, includes making an incision in the patient; inserting and advancing a first surgical instrument that spreads a second tissue to form a tunnel therein; inserting an insertion device loaded with the device through the incision; advancing the insertion device through the tunnel to the bone, the muscle, and/or the first tissue upon which the device is to be anchored; and anchoring the device to the bone, the muscle, and/or the tissue using the clip on the device

A subcutaneously implantable device includes a housing, a clip attached to the housing, a prong, and an electrode. The clip is configured to anchor the device to a muscle, a bone, and/or a first tissue. The prong has a base portion attached to the housing, an arm portion extending from the base portion so as to define a first plane that includes opposite ends of the arm portion of the prong and is perpendicular to a horizontal plane of the housing, and a contact portion that is configured to contact an organ, a nerve, the first tissue, and/or a second tissue. The contact portion is angled away from the first plane. The electrode is at the contact portion of the prong. The electrode is configured to contact the organ, the nerve, the first tissue, and/or a second tissue. Circuitry in the housing is in electrical communication with the electrode and is configured to provide monitoring, therapeutic, and/or diagnostic capabilities with respect to the organ, the nerve, the first tissue, and/or the second tissue.

A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

A tool includes a handle, a plunger actuator proximate the handle, a shaft extending from the handle, a plunger, an engagement mechanism. The shaft includes a proximal end and a distal end, and the shaft defines a channel extending along a length of the shaft. A first actuation of the plunger actuator causes the plunger to translate along the length of the shaft in a distal direction. A second actuation of the plunger actuator causes the plunger to translate along the length of the shaft in a proximal direction. The engagement mechanism is disposed on the distal end and is configured to engage an implantable medical device, and release the implantable medical device in response to the plunger exerting a contact force on the implantable medical device exceeding a reaction force of the engagement mechanism when the plunger translates along the length of the shaft in the distal direction.

The present disclosure is directed to devices, kits, and methods for treating lumbar spinal stenosis by at least partially decompressing a compressed nerve root. The method can include identifying the compressed nerve root and percutaneously accessing a region of a lamina located adjacent to the compressed nerve root. The method can also include forming a channel through the region of the lamina, wherein the channel can be formed medial to a lateral border of the lamina. Further, the method can include expanding the channel in a lateral direction.
