    摘要： A microsurgical device and methods of its use can be used for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. A dual-blade device can be used for cutting the trabecular meshwork (“TM”) in the eye. The device tip provides entry into the Schlemm's canal via its size (i.e., for example, 0.2-0.3 mm width) and configuration where a ramp elevates the TM away from the outer wall of the Schlemm's canal and guides the TM to first and second lateral elements for creating first and second incisions through the TM. The dimensions and configuration of the blade is such that an entire strip of TM is removed without leaving TM leaflets behind and without causing collateral damage to adjacent tissues.

    摘要： A catheter placement system including a catheter, a needle for creating an insertion site, and a skin nicking device for enlarging the insertion site. A catheter placement device includes the skin nicking device slidably coupled with the needle, where the skin nicking device has one or more blades attached to a frame thereof. Distally displacing the skin nicking device along the needle causes the blade to nick the skin to enlarge the insertion site. A shield of the skin nicking device transitions between a safe configuration encapsulating the blade and a use configuration exposing the blade and the shield may be biased toward the safe configuration. A latch secures the shield in the safe configuration and an actuator releases the latch. A sheath of the skin nicking device includes the needle slidably disposed within a lumen thereof and a sharp tip of the blade embedded within a wall thereof.
