  • Patent number: 10799693
    Abstract: A connector of the present invention includes a housing and a valve, wherein the housing has a flow path and a pipe connecting port, and the valve is formed of an elastic material and is adapted to block the pipe connecting port. The valve has a substantially columnar deformable portion. The deformable portion has a top surface exposed from the pipe connecting port, a bottom surface opposite to the top surface, and a slit that reaches extends from the top surface to the bottom surface. When the top surface is pressed by the pipe, the deformable portion of the valve will be displaced toward the flow path while elastically deforming, so that inner surfaces that define the slit will face the flow path, and the top surface will form an opening that communicates with the flow path.

    Abstract: A surgical seal assembly, includes a seal housing defining a longitudinal housing axis and having a longitudinal opening therethrough, a seal having an inner seal portion defining a passage and being adapted to form a substantial seal about a surgical instrument disposed within the passage and a guide mounted to the seal housing. The guide has an inner guide portion proximal of the inner seal portion of the seal and spaced therefrom. The inner guide portion defines a channel adapted to generally direct the surgical instrument toward the inner seal portion of the seal upon entry of the surgical instrument within the longitudinal opening of the seal housing. The inner guide portion is relatively compliant to accommodate initial offset or angled entry of the surgical instrument.

  • Patent number: 8864710
    Abstract: An infusion sleeve for use with a phacoemulsification needle has a hollow body with an open end by which the sleeve is attachable to a handpiece and an open tip through which a phacoemulsification needle is passed. Irrigating liquid is directed from the handpiece through the sleeve. At least one discharge ports is formed in the sleeve to provide increased flow of irrigating liquid into the eye. The port or ports may differ in size, shape and positioning on the sleeve. At least one such port has a slit extending therefrom cutting through the sleeve and adapted to distend or open up under certain flow conditions, effectively increasing the cross-sectional area of the port available for flow. When flow conditions return to normal the slit returns to its “closed” position. Another such port is formed as a flap which opens and closes responsive to the flow of the irrigating liquid.

  • Patent number: 8758302
    Abstract: In at least one embodiment, a hemostatic valve for use with a splittable introducer (10) is provided. The hemostatic valve (22) comprises a seal (24) molded in a first configuration of polymeric material and having two adjacent end surfaces (34,35). The seal is deformable from the first configuration into a second configuration. In the first configuration, the seal is substantially non-planer with the two adjacent end surfaces exposed. In the second configuration, the two adjacent end surfaces are unexposed so as to form a split extending through the seal.

  • Patent number: 8740874
    Abstract: A catheter includes an elongate body having first and second chambers extending within the elongate body from a proximal end to an intermediate section, the first chamber having a first opening and the second chamber having a second opening at the intermediate section. The catheter also includes a valve structure that may have first and second barrier elements to open or close the first and second openings, respectively. The first and the second barrier elements may be coupled by a connecting structure moving within an opening in a guide structure. Alternatively, the first and the second barrier elements may be coupled in a U-shaped structure that moves over the guide structure. To permit flushing of the chambers when the first and second openings are closed, the first and second chambers may also be connected by a connecting channel defined by an opening in a wall of the elongate body.
