A disc implant device can be provided in a generally planar rectangular sheet having a first elongated side, a second elongated side opposing the first elongated side, a first end, and a second end opposing the first end. The generally planar rectangular sheet is structured with alternating segments of joint ridges, each segment of joint ridges being configured to form a spacing joint segment and alternating segments of arm ridges, each arm segment being configured to form a plurality of radially extending arms, the joint segments providing flexibility to the device. When the disc implant is folded or rolled from its planar configuration to a generally cylindrical configuration, the arm segments are axially collapsible and radially expandable such that in such a configuration, the implant includes segments of radially expanded arms separated by spacing joint segments.

A method for treating spinal nerve compression includes sequential dilation to position an instrument cannula along a patient's spine. Instruments can be delivered through the instrument cannula to remove targeted tissue for a decompression procedure. One of the instruments can be a reamer instrument configured to abrade, cut, or otherwise affect tissue along the patient's spine.

Survival of patients suffering from many infections diarrheal diseases, including Ebola, as well as trauma and post-partum hemorrhage is improved with large-volume, parenteral, fluid replacement. In lieu of IVs, Intra-Osseous (IO) lines are placed with the help of a Humerus-Finder™, a one-piece guide that identifies the humeral head at the shoulder and allows for easy, safe, placement of an IO line. This guide enables healthcare providers and lay-providers to place IO lines and deliver fluids to infected persons without direct contact, limiting risk to providers. The Humerus-Finder™ makes early, potentially life-saving, supportive treatment available where large-volume fluid infusion can save lives and is useful in disaster medicine and emergency medicine when it is not possible to place an IV line rapidly and safely by helping first responders achieve IO access for delivery of fluid resuscitation in a safe, reliable manner.

A device is described for marking a path on a skin surface for inserting an epidural needle into an epidural space. The device includes a first arm having one or more holes spaced apart along the length of the first arm. A pin is attached at the proximal end of the first arm. A second arm has a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms. The second arm has one or more holes spaced apart along the length of the second arm. The holes on the first and second arms provide locations for marking the path on the skin surface to insert the epidural needle.

A surgical guide tool and methodology includes a non patient-specific platform including one or more supports for attaching to a body part of a subject. A non patient-specific block has a top planar surface and a bottom planar surface, and includes a guide aperture extending from the top planar surface to the bottom planar surface for guiding a surgical instrument in making at least one of a cut and a drill hole. An intermediate module is removably positioned between the platform and the block. The intermediate module has patient-specific dimensions such that the guide aperture has a desired alignment relative to the body part when the surgical guide tool is attached to the body part of the patient and the intermediate module is positioned between the platform and the block.

A puncture device guide includes a guide platform configured to releasably attach to an ultrasound probe, a guide tower slidingly coupled to the guide platform, and a needle holder device for coupling to a puncture device. The guide tower projects upwardly from the guide platform and includes a vertical guidance slot and a plurality of attachment positions for engaging the needle holder device.

Provided is a guide device for puncturing with a puncture needle from a puncture point A provided at a vicinity of a first point B on a waist of a patient to a target point D inside a patient's body, the target point D corresponding to a second point C different from the first point B on the waist. The guide device includes a guide part for guiding the puncturing with the puncture needle, and a support base for supporting the guide part and abutting on the waist. A portion of the support base is configured to define a first angle with respect to a straight line connecting the puncture point A and the second point C, and the guide part is provided at a second angle with respect to a line perpendicular to the support base. The first angle is defined by the puncture point A, the second point C and the first point B, and the second angle is defined by the puncture point A, the target point D and the second point C. Accordingly, it is possible to provide a guide device capable of easily and accurately puncturing a target point with a puncture needle regardless of a patient or an operator.

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.

The present invention provides a puncture support, including a support body and a soft support coating covering the outside of the support body, wherein a needle insertion channel is provided inside the support body. During use, the puncture support is fixedly connected to an ultrasonic probe by using the hard support body, and the soft support coating attached to the support body is in contact with a human body. Because the support coating is made of a soft material, people feel soft with reduced foreign body sensation when in contact with the support coating. In addition, the support body is made of a hard material, so that the puncture support can be firmly installed, ensuring safety. Therefore, the puncture support can be firmly and reliably installed like an existing puncture support, and also increases the comfort level of the product by taking user feelings into account.

Systems, apparatus, and methods are described for forming an incision in tissue for receiving a surgical instrument. A cutting device for forming the incision can be reversibly coupleable to an instrument, e.g., a dilator. The instrument may define a lumen configured to receive a wire that extends or is otherwise extendable through a puncture site. The cutting device can include a cutting element configured to be actuated to form the incision such that the incision extends form the puncture site and is sized to receive the instrument.
