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.

An intraluminal, balloon expandable stent for implantation in a body lumen is disclosed. The present invention provides a lumen support stent with an unobstructed through-lumen for use in a blood vessel. A constraining mechanism is provided for securely maintaining the stent in the collapsed condition during delivery. The stent is preferably formed with a series of interconnected slide and lock mechanisms for permitting movement from a collapsed condition to an expanded condition and inhibiting radial recoil from the expanded condition. The stent may be formed from a shape memory alloy for providing crush-recovery after deployment.

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.

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.

A device for controlling the collection and delivery of materials to a patient, the device has a dispenser-engaging portion, the dispenser-engaging portion being operable in a release position to receive a materials dispenser when the dispenser is in a materials-containing configuration, the dispenser-engaging portion being operable in a lock condition for locking the dispenser therewith, and access control means for controlling the release and lock positions according to a material transaction condition.
摘要:
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.
