Abstract: A low-profile universal passive protector for an IV catheter includes a connector having a tubular body and a pair of arms pivotally connected thereto. The tubular body defines an end face and the connector includes a cavity extending from the end face. An elongate sheath is snap engageable to the tubular body. A spring is insertable within the connector cavity to extend between at least one of the pair of arms and the elongate sheath when received within the cavity. A slider is moveably coupled to the sheath. The slider includes a flashback chamber formed therein. A hypodermic needle is connected to the slider and is in fluid communication with the flashback chamber. The slider is moveable along the sheath between a first position and a second position, with the hypodermic needle being drawn into the sheath as the slider moves from the first position toward the second position.

Abstract: Disclosed herein are systems, devices, kits, and associated methods for excising tissue. A device for excising tissue may include a body, a first curved member coupled to the body and having a first tissue contact surface, a second curved member movable relative to the first curved member and comprising a second tissue contact surface, an actuator coupled to the body and configured to decrease a distance between the first and second curved members, and a cutting assembly configured to excise the tissue. The first tissue contact surface may have a first radius of curvature (ROC), while the second curved member may have a second, smaller ROC. Further, one or portions of the device, such as one or both of the first and second jaws, may be transparent and/or may include markings to facilitate accurate aligning of the device relative to a tissue excision site.

Abstract: An elastic band ligation device enables a clinician to deploy multiple ligation bands without an assistant and without the need for an external aspirator. A ligation band may be loaded onto a distal end of the ligation device using a detachable loading device, and a pusher may be provided to advance the band from the loading device onto the ligation device. Kits may be provided, for enabling the loading of two or three or more successive ligation bands onto a common ligation device in a single procedure. Methods are also disclosed.

Abstract: A low-profile universal passive protector for an IV catheter includes a connector having a tubular body and a pair of arms pivotally connected thereto. The tubular body defines an end face and the connector includes a cavity extending from the end face. An elongate sheath is snap engageable to the tubular body. A spring is insertable within the connector cavity to extend between at least one of the pair of arms and the elongate sheath when received within the cavity. A slider is moveably coupled to the sheath. The slider includes a flashback chamber formed therein. A hypodermic needle is connected to the slider and is in fluid communication with the flashback chamber. The slider is moveable along the sheath between a first position and a second position, with the hypodermic needle being drawn into the sheath as the slider moves from the first position toward the second position.

Abstract: A synchronous belt drive system having: a synchronous belt with a tensile cord of high-modulus fiber such as glass, carbon, PBO, or aramid; a driver sprocket and at least one driven sprocket, at least one of which is an obround sprocket; and a tensioner having: a base having a cylindrical portion extending axially with a radially outer surface and a receiving portion, an eccentric arm pivotally engaged with the radially outer surface, a torsion spring disposed within the receiving portion, the torsion spring applying a biasing force to the eccentric arm, and a pulley journalled to the eccentric arm. Preferably, no one of the eccentric arm, pulley, or torsion spring is axially displaced along an axis A-A from the others. The obround sprocket has a toothed surface and at least one linear portion disposed between two arcuate portions having a constant radius, the linear portion having a predetermined length.

Abstract: The present invention is directed to improved methods, devices, and systems for eye surgery. In some embodiments, the invention may provide new and/or improved devices, systems, and methods for detecting surgical fluids in a fluidics cassette, particularly cassettes which are used to couple an eye treatment probe to an eye treatment console. Rather than relying on internal reflection by a gas-liquid interface, the fluid detection techniques described herein may make use of the changes in propagation of light through a portion of the holding tank when the portion varies between empty and full. Other aspects of the invention may provide devices, systems, and methods for producing different types of fluidics cassette using a single cassette body type.

The horn may have one or more notches distributed around an outer surface of the horn, wherein the one or more notches enable the distal end of the needle to vibrate in the transverse and longitudinal directions when power is applied.

Abstract: Devices, systems, and methods interface a cassette with an eye treatment system console to provide coupling between the console and an eye treatment probe. The console may receive the cassette using a driven axial translation linkage that inhibits rotation of the cassette. The cassette may facilitate accurately positioning of a pressure sensor relative to a the console by allowing sliding movement between the sensor and a cassette body. Multiple peristaltic drives may be mounted to the console so that their rotors rotate about a common axis. An integrated mount structure may support and/or position components of the console which will interface with cassette, and an axially compressible vacuum connector of the console seal to a tapered vacuum coupler of the cassette.
