Abstract: A surgical access device includes a cannula and a housing coupled to the cannula. A cannula lumen and a housing interior communicate to define a working channel that extends along a central axis of the device between proximal and distal device ends. A needle entrance port is arranged on a side portion of the housing and opens to the working channel. A needle exit port is arranged distally of the needle entrance port on a side portion of the cannula, and communicates with the needle entrance port to define a suture path extending through the surgical access device at an oblique angle relative to the central axis. The needle ports are configured to guide a suture passer device distally through the surgical access device and first and second tissues of different thicknesses, while maintaining the same tissue bite distance in each of the first and second tissues.

Abstract: Provided is a device for injecting a fixed quantity of liquid medicine, to which a syringe may be mounted and which may inject the liquid medicine held in the syringe by a fixed quantity due to a user's pushing operation. The device for injecting the fixed quantity of liquid medicine is advantageous in that a user can operate the device with one hand to inject the fixed quantity of medicine into various areas, thus maximizing operability and convenience. Furthermore, the device is advantageous in that it is possible to maximize medicine delivery efficiency even when operated by a person who is not a medical staff not in a hospital but at home.

Abstract: An embolic agent and a piezoelectric substance are mixed together. The mixture can be delivered to a tumor or other object by a non-invasive method. The embolic agent prevents movement of the piezoelectric substance from the target location. Subsequent impulses applied to the target location cause ablation of the surrounding area due to the piezoelectric effect of the particles, promoting highly accurate and precise ablation without the need for more invasive procedures.

Abstract: Valve assemblies having improved ability to selectively control flow of fluids through the catheter and prevent leakage of fluids from the proximal end of a catheter that is positioned within a patient.

Abstract: An intraosseous access device can include a device body, a trocar needle, and an intraosseous catheter removably disposed on the trocar needle. The device body can be configured to enable a user of the access device to manually insert a distal tip of the trocar needle through a skin surface of a body of a patient to an external surface of a bone of the patient. The intraosseous access device can include a first advancement member configured to provide a first distal advancement force sufficient to distally advance a distal tip of the trocar needle and the catheter through a skin surface to an external surface of a bone of a patient, and a second advancement member configured to provide a second distal advancement force sufficient to distally advance the distal tip of the trocar needle and the catheter through the external surface of the bone.

Abstract: A handle shaft is disposed at a proximal end of a catheter. A wire extends from a distal part of the catheter, proximally through the catheter to the handle shaft. A knob is disposed outside of the handle shaft. A threaded mechanism provides operative coupling between the knob and the handle shaft such that (i) rotation of the knob with respect to the handle shaft alters tension in the wire via the threaded mechanism functioning as a linear actuator; and (ii) non-rotational axial movement of the knob with respect to the handle shaft alters tension in the wire without the threaded mechanism functioning as a linear actuator. Other embodiments are also described.

Abstract: An anchor system for securing a vascular access device to a patient may include an anchor pad, which may include a lower surface, an upper surface, and a window extending through the anchor pad. The system may also include the vascular access device, which may include a body and a stabilization platform extending from the body. The anchor pad may be coupled to and extend distally from the stabilization platform.

Abstract: The present invention enables the completion of preparation of liquid medicine injection to be easily and quickly checked with the naked eye based on a color change in an endcap for a liquid medicine-injecting tube. As long as a medical staff checks a color change in the endcap with the naked eye, the medical staff can immediately perform an operation of connecting the tube to a catheter (or injection needle) or the like after removal of the endcap without unnecessarily draining off a large amount of the liquid medicine.

Abstract: An introducer sheath for providing access in a patient's body comprises a tubular body with a distal portion and a proximal portion, the proximal portion being configured to be inserted into the patient's body to allow a medical device to be inserted through the introducer sheath into the patient's body. In order for the introducer sheath to be removable from the patient, it can be separated along its length in a longitudinal direction. The introducer sheath further comprises at least a first handle which is pivotable about a fulcrum. The first handle has a first end portion and a free second end portion so as to form a lever, such that pivoting the handle about the fulcrum causes a contacting portion of the handle to act on a respective counter portion that is operatively connected to the distal portion of the tubular body. This creates a breaking force that causes the distal portion of the tubular body to break.
