摘要:
A disposable unit for delivering fluid medium to one of a plurality of patients includes a sterile patient supply tube, and structure for receiving pressurized fluid medium into the patient supply tube. One or more devices is provided for precluding backflow of material from the patient to the fluid medium receiving structure, for preventing contamination of the fluid medium receiving structure and/or for preventing cross-contamination between patients.

Various methods for optimizing coating of medical devices, such as balloon catheters are disclosed. One method configures catheter balloon folds based on balloon diameter and volume. Other methods include using a specifically-sized protective sheath, using a vacuum, using pressure, pulling the balloon through a coating solution, using at least one spacer or a wick between at least one fold for metering a therapeutic coating into the folds of the balloon, placing an intermediate layer between the balloon and the therapeutic coating, placing a soluble film having a therapeutic agent around the catheter balloon or inside the folds, and any combination thereof. Balloon catheters and catheter balloons having a specific folding configuration, a specifically-sized protective sheath, an intermediate layer, or a soluble film are also disclosed.

A hazardous fluid transport container and a hazardous fluid delivery system are disclosed. The hazardous fluid transport container includes a housing enclosing an at least partially shielded enclosure. First and second fluid path elements are disposed within the housing, with the first fluid path element and second fluid path element fluidly coupled together. A pump unit may be provided for dispensing fluid from the first and second fluid path elements optionally into a third fluid path element. Also, methods for priming the hazardous fluid transport container and for mitigating laminar flow injection bolus spreading are disclosed. Additionally, disclosed is a radioactive fluid transport container for a syringe or other container. The radioactive fluid transport container allows the syringe or container to be used in an injection procedure without removal from the container.

A system for the collection, management, and dissemination of information relating at least to a medical procedure is disclosed. The system includes a user interface adapted to provide raw data information at least about one of a patient, the medical procedure, and a result of the medical procedure. A medical device communicates with the user interface, receives the raw data information from the user interface, and generates operational information during use. A central database communicates at least with the medical device and receives data from the medical device. The central database is used to create related entries based on the raw data information and the operational information and optionally transmits the related entry to the medical device or the medical device user. The related entry includes information that provides guidance based on previously tabulated, related medical procedures. A system for the iterative analysis of medical standards is also disclosed along with methods for the evaluation of medical procedures and standards.
摘要:
A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and a catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluids in the manifold press on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to a pressure of the pressurized fluids. In the open configuration, the pressure actuated seal element relaxes in an absence of the pressurized fluids, and the seal element lumen is open and configured to allow passage of an instrument.
摘要:
A method of substituting an MRI incompatible pump for delivering fluid to a patient with an MRI compatible pump, both pumps being microprocessor controlled. The first pump operates upon administration tubing for pumping fluid from a source thereof to the patient. The method includes the steps of: providing the second pump to be substituted for the first pump; providing second tubing having a portion thereof that is operable to function with the second pump; connecting the second tubing to the administration tubing to establish an altered fluid path from the source to the patient, the altered path including portions of both the administration and second tubing; placing the second pump for operation upon the second tubing to enable the second pump to pump the fluid through the altered path according to programming thereof; and disconnecting the first pump from the administration tubing before bringing the patient into the MRI environment.
