摘要:
An apparatus for controlled flow of fluid materials for use with medical accessories has a first housing with a body, a first open end, a second open end, and a hollow interior. The second end fits with a first medical accessory for flow of fluid materials from the first medical accessory. A fluid flow control means is disposed within the housing for controlling the flow of fluid materials through the hollow interior from the first medical accessory. The apparatus also has a second housing with an open end, a first open end, a hollow interior, and a second open end having an axial bore coaxial with the hollow interior of the first housing. The second end of the second housing fits with the first open end of the first housing. The first open end of the second housing fits with a second medical accessory, whereby the second medical accessory receives fluid materials from the first medical accessory by way of the hollow interior of the body.

A medical delivery device comprising an elongate body having a plunger slidably and sealingly engaged to form a cavity to receive fluid materials and a first outlet disposed at an end of said body and has a male luer end portion and a valve assembly is disposed within the first outlet. The valve assembly has a valve means movable between an open position and a closed position and biasing means for biasing the valve means to a closed position. Actuating means are disposed within the male luer end portion and coupled to the valve means such that the valve means is movable to an open position when a female luer end portion of a medical accessory is coupled with the male luer end portion. A second outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the environment to said cavity under the action of the plunger. Lastly, a third outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the cavity to the environment under the action of the plunger.

An apparatus for controlled flow of medical fluid materials for use as an adapter in place of a septum in an outlet of a medical fluid container, has a body with a hollow interior, a first open end adapted for fluid tight fit with the outlet of the medical fluid container, and a second open end adapted for fit with a medical accessory. A fluid flow control means is disposed with the body for controlling the flow of medical fluid materials through the hollow interior between the medical fluid container and the medical accessory. The fluid flow control means comprises a valve member, a valve seat, and biasing means operating on the valve member to bias the valve member against the valve seat for fluid tight fit. The valve member is motivated to open fluid communication between the medical fluid container and the medical accessory when the medical accessory is attached to the second open end and the valve member is motivated to close fluid communication between the medical fluid container and the medical accessory when the medical accessory is disengaged from the second open end.

A method and system are disclosed for rapid placement of tubes within a body cavity that includes placing a compliant cannula over a probe tip of a cutting device until the probe tip extends beyond the cannula, incising the tissue covering body cavity to create an opening therein, inserting the probe tip of the cutting device until the cannula placed thereon extends into the incision, removing the probe tip while leaving the cannula inserted within the incision, introducing a distal end or tip of a tube into the cannula a predetermined distance, and removing the cannula over the tube while retaining the tube in position within the body cavity. The device includes a sealing portion which attaches to the body without sutures and having an opening therethrough, and a tube which passes through the opening of the seal and mates thereto without sutures.

Disclosed herein is a system for the collection, treatment and delivery of an autologous blood sample, comprising a first syringe having a first body portion. A first sample transfer portion has a first syringe inlet for drawing an untreated blood sample from a patient and a first syringe outlet for dispensing the untreated blood sample. A blood sample treatment chamber having a chamber inlet, the first syringe outlet being operable to establish a dedicated first fluid coupling with the chamber inlet to dispense the untreated blood sample to the blood sample treatment chamber. The blood sample treatment chamber having a chamber outlet for dispensing a treated blood sample following treatment. The second syringe has a second body portion and a second sample transfer portion, the second sample transfer portion having a passage with a first access location which is operable to form a dedicated second fluid coupling with the chamber outlet. The second body portion has a second syringe outlet, the passage having a second access location for fluid communication with the second syringe outlet, releasable lock means for forming a locked third fluid coupling between the second access location and the second syringe outlet. The lock means is operable in response to a release signal to release the third fluid coupling, the second syringe outlet being operable when released from the third fluid coupling to form a fourth fluid coupling with a blood sample delivery unit.

Disclosed herein is a syringe assembly for discharging gaseous materials from a syringe, comprising an elongate container with a plunger slidably and sealingly engaged therein to form a fluid material receiving cavity, the container further comprising an outlet for dispensing fluid materials from the cavity; the plunger including transfer means for transferring gas constituents from the cavity to a region outside the cavity.
摘要:
The invention relates to an expandable stent comprising circumferentially adjacent modules. The modules comprise longitudinally adjacent slide-and-lock radial elements which permit one-way sliding of the radial elements from a collapsed diameter to an expanded/deployed diameter, but inhibit radial recoil from the expanded diameter.
