A system and method for video assisted percutaneous needle cricothyrotomy and tracheostomy to assist physicians in quickly intubating patients suffering from respiratory distress when oral or nasal intubation is not possible or contraindicated. The system and method includes a display monitor, a percutaneous needle assembly including a connection hub having a syringe port for removably attaching a syringe, a needle port for attaching a hollow needle, and a stylet port in communication with the needle port for receiving a fiber optic stylet that extends through the hollow needle. The fiber optic stylet includes one or more illuminators, and a camera for capturing and transmitting anatomical images for display on the display monitor to visually assist physicians in locating a patient's trachea lumen. The fiber optic stylet is positioned within the trachea lumen, and used as a guide wire to insert a dilator and cannula for ventilating the patient.

An apparatus for preventing deployment failure or damage of a movable portion of a treatment device via a force limiting element in the treatment device.

A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.

A tympanostomy tube placement device has a needle with a tip, and a retainer at the needle tip. The retainer is within and retains by pulling radially inwardly a tympanostomy tube distal flange in a folded configuration extending distally. Movement of the needle tip in the proximal direction causes the adhesive bond to break and the distal flange releases to an unconstrained deployed position. Due to the axial folding of the distal flange its radial dimension does not affect deployment through the membrane.

In some embodiments, disclosed herein are systems and methods of treating a patient that can include the steps of accessing the sphenopalatine fossa, and cannulating the inferior orbital fissure from the sphenopalatine fossa to access the retro-orbital space. The sphenopalatine fossa can be accessed via various routes, including percutaneously. Accessing the sphenopalatine fossa can include the step of inserting a needle-catheter system into the sphenopalatine fossa. Integrated needle-catheter systems as described herein can also be configured to access the trigeminal ganglion, epidural space, intrathecal space, and other desired anatomical locations.

A device for regulating blood pressure between a patient's left atrium and right atrium, and apparatus for delivery the device, are provided. The delivery apparatus may include one or more latching legs, a release ring, a pull chord, and a catheter wherein the latching legs are configured to engage the device for delivery. The inventive devices may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices may be used, for example, to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies.

The disclosure is directed to an implant tool and cannula used to facilitate the implantation of a medical device into a patient. The implant tool includes a housing that is held by a user and a needle attached to the housing. The cannula may be positioned over the needle and delivered to a target tissue within the patient. The cannula includes an electrode at a distal portion to deliver test stimulation to confirm the location of the target site or placement of the implant tool relative to the target site before removing the needle of the implant tool. In this manner, the cannula may be repositioned within the patient until the position of the implant tool and cannula relative to the target site is verified with the test stimulation.

Disclosed is an artificial intelligence-based cannula surgery diagnostic device. The device includes a cannula stroke sensing unit for sensing a stroke of a cannula generated in a surgical procedure of a patient; a surgical data processing unit for receiving surgical data generated based on a stroke of the cannula; and a surgical prognostic information-generating unit for analyzing the received surgical data based on the existing learned surgical data to generate surgical prognostic information for the patient.

A precision forward-looking image-guided diagnostic and therapeutic surgical probe and needle insert for microsurgery in support of imagery, neurology, neurosurgical procedures, and ophthalmic surgical applications comprising an introducer needle (stylet), a fiber carrier, a therapeutic conduit, and a spirographic method for scanning a target and associated algorithms to create and render a reconstructed image for display to a physician in real-time or near real-time. The probe implements Optical Coherence Tomography (OCT) to provide high-resolution extended imagery of an intended therapeutic or target tissue. A separate therapeutic conduit provides surgical access for therapeutic devices such as a cutting or ablation laser, an RF electrode for locally heating tissue, a lumen for local injection of neurolytics/paralytics, placement of electrodes for neuromodulation, and deployment of a micro-endoscopic imaging tool. A third working channel supports the delivery of neurolytic and other fluids.

A device and method is provided to gain access to interior body regions. The system includes a safety needle assembly, a stylet assembly, a blade assembly, an obturator assembly, and a dilator assembly. The safety needle assembly or stylet assembly accesses an interior body region, after which the blade assembly expands the pathway created by the safety needle assembly or stylet assembly. The obturator then further expands the pathway and delivers the dilator assembly to the desired location. The safety needle assembly, obturator assembly, and blade assembly are removed, leaving the dilator assembly in place for future procedures.
