A cortical access system for delivering a medical tool into an epidural and/or subdural space and onto a patient's brain tissue through a cranium opening comprises: a turret including a proximal end portion, a distal end portion, and a first channel extending from an entrance opening to an exit opening, the first channel configured to guide the medical tool from the entrance opening to the exit opening for positioning on the patients brain tissue. The medical tool may be an electrode or an endoscope.

Devices and methods for performing subcutaneous surgery in a minimally invasive manner are provided. The methods include application of reduced air pressure in a recessed area of a handpiece placed over a section of skin and drawing the section of skin and subcutaneous tissue into the recessed area. In a subsequent step a tool is inserted through a tool conduit in the handpiece and through the skin into the subcutaneous tissue, enabling the performance of the desired surgery. Common surgical procedures include dissection and ablation. The devices and methods can be directed at the treatment of skin conditions like atrophic scars, wrinkles, or other cosmetic issues, at treatments like or promoting wound healing or preventing hyperhidrosis, or can be used for creating space for various implants.

A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.

The subject invention provides devices and methods for alleviating discomfort associated with neuroma formation. The devices and methods of the invention effectively use the body's natural response of reconstructing implanted biomaterials to minimize the size of, isolate, and protect a neuroma. In preferred embodiments, the subject device is a cylindrical cap, wherein the internal chamber of the cylindrical cap physically partitions the nerve to enable an arrangement of nerve fibers (as opposed to haphazardly arranged nerve fibers often produced in neuromas). Tabs arranged on the outside of the cap can be used to manipulate the cap into place on a nerve. The open end can also be configured with flaps that can be used to widen the open end for easier insertion of the nerve into the cap. In addition, the cap's material remodels into a tissue cushion after implantation, which protects the neuroma from being stimulated and inducing pain.

A support assembly for supporting a biological product (e.g., membrane) in an operative position. The support assembly has a base and a cover. A membrane receiving portion of the base defines a plurality of perforations that extend between top and bottom surfaces of the product receiving portion. The cover is releasably coupled to the base in a product-covering position in which the cover overlies the product receiving portion of the base. In the operative position, the biological product engages the top surface of the product receiving portion and the bottom surface of the cover.

The present disclosure relates to devices and methods for partly isolating a target biological structure. The device may include a main body comprising a front face and a rear face, the main body having a proximal end and a distal end. The distal end may be arcuate in a first state and may be substantially planar in a second state. The device may further include one or more balloons disposed on the distal end of the main body. Each of the one or more balloons is deflated in the first state and each of the one or more balloons is inflated in the second state. The distal end of the main body is configured to deform to be substantially planar when each of the one or more balloons are inflated in the second state.

Systems, methods, and media for wireless radio frequency lesioning are provided. In some embodiments, a system for wireless radio frequency comprises: a wireless radiofrequency device, comprising: a receiving coil, a plurality of capacitors coupled in parallel to the receiving coil, a first electrode, and a second electrode, wherein a capacitor of the plurality of capacitors is connected between the first electrode and the second electrode, and wherein capacitances of the plurality of capacitors cause the receiving coil to pair with a transmitter at an operating frequency; a transmitter comprising at least one transmitting coil; and a radiofrequency generator configured to apply a radiofrequency signal at the operating signal to the transmitter.

Methods and devices for visualising an implant in a retina are provided. A 2D image of the retina is taken and OCT scans of the retina and implant are carried out. Based thereon, the implant and retina are visualised.

A surgical anchor device for being anchored on the mucous membrane of the inner wall of the intestine, the device having a temporary anchor element presenting anchoring that can be modified in a controlled manner and having a first substantially cylindrical multiply-perforated wall presenting properties of radial elasticity whereby the first wall presents an outer diameter that can be varied in controlled manner, wherein a portion of the inner surface of the first wall is lined with an independent leakproof inner sheath having only its longitudinal ends fastened to the anchor element to define a suction chamber between the inner sheath and the first wall, the temporary anchor element being coupled to a flexible or semi-rigid tube extending outside the anchor element, an open end of the injection-suction tube opening out into the suction chamber enabling air to be injected into or sucked out from the suction chamber.
