    摘要: A expandable prosthesis having an imageable structure comprising one or more elements visually distinguishable by an external (e.g., radiographic or ultrasonic) imaging system, the structure being located about a first axis that corresponds to a structural feature of the prosthesis that is configured to perform a specific function particular to that axis. The imageable structure is configured to assist in the rotational orientation of the prosthesis during placement within the implantation site. In one embodiment, the prosthesis comprises a venous valve that includes imageable elements or structure, such as a pair of radiopaque markers, that defines the orifice of the valve structure such that the orifice can be oriented with a particular anatomical feature under imaging, such as to align the orifice with the long axis of the vessel. In another embodiment, the imageable structure is configured to permit an aperture located about a stent graft to be oriented with a anatomical feature of the vessel, such as a branch vessel opening. The invention includes a method for using imageable structure to confirm that the orientation of the prosthesis within a delivery apparatus is consistent the desired delivery approach to be used.

    摘要: Medical devices for implantation in a body vessel are provided. A medical device according to the invention comprises a support structure and one or more graft members comprising a valve portion and a constraining portion. The support structure has a first, unexpanded configuration and a second, expanded configuration. The constraining portion is adapted to substantially prevent the support structure from achieving the second, expanded configuration. The valve portion is adapted to permit fluid flow through a body vessel in a first direction and substantially prevent fluid flow through the vessel in a second, opposite direction.

    摘要: A pressure injection syringe with an actuator that includes a plunger for pressurizing viscous fluid material within a chamber. The plunger distal tip includes a high pressure seal defined by a seal member within a seal seat. The high pressure seal is viscoselective to permit air passage therepast for aspiration, and to prohibit viscous material passage therepast during actuation of the actuator wherein high pressure is applied to the material within the chamber. The viscoselective seal may be defined for example by small axial openings in the seal seat that permit aspiration of air therepast during initial plunger insertion into the chamber, but fluid escape is prohibited by the seal member when the seal member is pressed firmly against a collar of the plunger proximally adjacent the seal seat by initial engagement of the seal member with the viscous material, thus completely sealing the chamber at the proximal end thereof.

    摘要: A pressure injection syringe (10) with an actuator (100) that includes a plunger (102) for pressurizing viscous fluid material within a chamber (14). The plunger distal tip (112) includes a high pressure seal (110) defined by a seal member (118) within a seal seat (116). The high pressure seal (110) is viscoselective to permit air passage therepast for aspiration, and to prohibit viscous material passage therepast during actuation of the actuator wherein high pressure is applied to the material within the chamber (14). The viscoselective seal (110) may be defined for example by small axial openings (130) in the seal seat (116) that permit aspiration of air therepast during initial plunger insertion into the chamber, but fluid escape is prohibited by the seal member (118) when the seal member is pressed firmly against a collar (126) of the plunger (102) proximally adjacent the seal seat by initial engagement of the seal member with the viscous material, thus completely sealing the chamber (14) at the proximal end thereof.
