Surgical access stabilization devices, systems, and methods are disclosed herein. For example, the devices, systems, and methods disclosed herein can be used during a surgical procedure to selectively establish, stabilize, and maintain a desired trajectory and/or positioning of a surgical access device. An exemplary surgical access stabilization device can include a pad with an adhesive distal facing surface to adhere to an anchor surface, a surgical access device coupled to the pad, and a locking mechanism to selectively lock a position of the surgical access device relative to the pad. In one embodiment, the anchor surface can be the skin of a patient. An exemplary surgical access device stabilization method can include making an incision in a patient at a surgical site, inserting a surgical access device through the incision, adhering a pad to an anchor surface, e.g., the skin of the patient, coupling the surgical access device to the pad, and selectively locking a position of the surgical access device relative to the pad. Other exemplary devices, systems, and methods are also provided.

An adsorption head includes a body. The body is a hollow housing, one side of the housing to which an adsorbed object is adsorbed is provided with an opening. The body comprises at least one adsorption chamber and at least one operation chamber therein, wherein the operation chamber and the adsorption chamber are spaced from each other and each have an opening orientated to the adsorbed object. The body has at least one adsorption passage and at least one operation passage thereon, wherein one end of the adsorption passage is communicated with the adsorption chamber, and one end of the operation passage is communicated with the operation chamber.

The present disclosure relates to cannula systems for delivery of a therapeutic agent to parenchymal tissue of a target subject. In certain embodiments, the cannula system is for delivery of a therapeutic agent to parenchymal tissue in the spine of a target subject. In certain embodiments, the cannula system includes a cannula positioning guide (CPG) useful in the delivery of a therapeutic agent to a localized target tissue of a subject. The guide may be used in a surgical suite or during a surgical procedure.

An introducing device for locating a tissue region and deploying an electrode is shown and described. The introducing device may include an outer sheath. An inner sheath may be disposed within the outer sheath. The inner sheath may be configured to engage an implantable electrode. In an example, the inner sheath may comprise a stimulation probe having an uninsulated portion at or near a distal end of the delivery sheath. The outer sheath may be coupled to a power source or stimulation signal generating circuitry at a proximal end. A clinician may control application of the stimulation signal to a tissue region via the outer sheath.

Tactile sensing devices, systems, and methods to image a target tissue location are disclosed. When force is applied to the tactile sensing device, voltage data is detected and visualized on a screen, indicating the target tissue location.

A system and method for implanting devices into biological tissue (e.g., brain tissue). The system may include a biocompatible probe, an integrated circuit (IC) chip tethered to the probe, a cartridge comprising a temporary attachment surface by which the probe is removably coupled to the cartridge, a needle to reversibly engage with the probe, a robotic arm to hold the needle, and a microprocessor controller. The microprocessor controller may control the robotic arm and the needle to remove the probe from the temporary attachment surface using the needle, pierce the biological tissue with the needle and the probe, withdraw the needle while leaving the probe within the biological tissue, and detach the IC chip from the cartridge, leaving the IC chip with the biological tissue.

An apparatus for attaching a medical device to a subject's body, either directly to the subject's body or to an intermediary element on the subject's body. The apparatus prevents substantially any relative movement between the medical device and the subject's body. Such an apparatus comprises: (i) a back base positioned between the subjects body and a surface that the subject lies thereon, (ii) at least one set of straps connected to the back base and to at least one of the medical device and the intermediary element, and (iii) at least one set of connectors providing a connection between the at least one set of straps and one or more of the medical device, the intermediary element and the back base. The apparatus may further comprise any of pivoting connectors, a respiration sensor, and straps with a stretchable section. The apparatus may be used in combination with a sterile drape.

An ophthalmic medical device for separating layers of eye tissue is disclosed. The device may include a supporting structure for supporting the eye and the supporting structure may have at least one stabilizing feature that stabilizes the eye to reduce movement. The supporting structure may define at least one hollow channel for positioning a needle that is inserted into the cornea to make a fluid bubble that separates the Descemet's Membrane away from the underlying stroma. In some embodiments, the fluid bubble enables an easy, clean separation of the layers to later be transplanted in patients needing corneal transplants.

A device and system for and methods of using an ultrasound probe housing containing ultrasound probes configured to produce images inside the body of a patient for procedures requiring needle or probe insertion. The ultrasound probe housing can be configured with a guide channel cut-out or aperture between the ambient side and body side of a patient. A needle guide assembly may be pivotally connect internal to the guide channel cut-out or aperture of the ultrasound probe housing at a pivot point such that during use the needle enters the patient through the needle guide assembly within the ultrasonic probe housing so that the needle can be visualized by the ultrasonic probes in real time. The ultrasound probe housing may also provide an adhesion or suction quality to the body side of the device to facilitate aspects of the invention.

There is provided a medical support device for holding and positioning a needle. This device is particularly useful for positioning needles in a less invasive puncture treatment. This device comprises two rotational elements and at least one needle guide attached to a rotational element and. The needle guide guides the direction of insertion of a needle-like instrument and includes a guide portion that guides a needle or other needle-like instrument where the puncture point of the needle in a first position is different from the puncture point when the needle guide guides the needle in a second position.
