A delivery adapter which may be used as an interface between a syringe and a catheter hub is described.

A method of performing a power injection procedure, including taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port. The access port defines one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum. The method further includes identifying the indicating radiographic feature on the x-ray, and in accordance with the presence of the indicating feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.

Method and system for treating a patient using a compressible, pressure-attenuating device. According to one embodiment, the system is used to treat urinary tract disorders and can include one or more of an access device, a delivery device, a pressure-attenuating device, and a removal device. The access device may be used to create a passageway to an anatomical structure, such as the patient's bladder. The delivery device may be inserted through the passageway created by the access device and may be used to deliver the pressure-attenuating device to the anatomical structure. The removal device may be inserted through the passageway created by the access device and may be used to view the bladder and/or to capture, to deflate and to remove the pressure-attenuating device.

A method of using a power-injectable port includes obtaining the power-injectable access port, attaching a catheter to an outlet stem of the power-injectable access port, and implanting the power-injectable access port and the catheter into a patient. The method further includes identifying the power-injectable access port following the implanting, inserting a distal end of a needle through the septum and into the reservoir, and injecting contrast media through the needle at a rate of at least one milliliter per second. The power-injectable access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is rated for injection of contrast media at a flow rate of at least 1 milliliter per second. The power-injectable access port is structured for operation at a pressure in the reservoir of at least 35 psi.

A respiratory device for supplying breathing air to a patient, including an oxygen inlet to be connected to an oxygen supply, and a compressed air inlet to be connected to a compressed air supply. The respiratory device also includes a turbine for sucking in ambient air. Switching between the individual operating modes can be done automatically or manually.

A venous access port assembly having a housing base with a discharge port, a septum, and a cap, with an interior reservoir. The housing base is provided with X-ray discernable indicia to identify an attribute of the assembly after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute. Such indicia can be depicted as cutouts through a disc of radiopaque material where the cutouts are in the form of alphabetical letters such as CT, or can be a set of discrete elements of radiopaque material, that are affixed along the bottom surface of the housing base or embedded within the thickness of the bottom housing wall.

The present application includes a sheath that is suitable for use in a variety of medical procedures. In one or more implementations, the sheath includes a shunt member, and a curvable portion. The curvable portion may be configured in various orientations to facilitate an intervention, such as a hemodialysis intervention, or the like, by an operator. The curvable portion may be configured to bend between a substantially straight configuration and a curved configuration. In implementations, the sheath may be configured to have detachable and/or interchangeable components (e.g., shunt member, curvable portion, etc.).

A flow sensor sub-assembly includes a flow tube having a lumen, an outside diameter, a first end, and a second end. An inlet fitting includes a conical orifice sized for insertion in either end of the flow tube, such that an internal passage of the inlet fitting is coaxial and concentric with the lumen and the end of the flow tube abuts a shoulder. An outlet fitting includes a conical orifice sized for insertion in either end of the flow tube, such that an internal passage of the inlet fitting is coaxial and concentric with the lumen and the end of the flow tube abuts a shoulder. A first piezo element integrated with the inlet fitting is arranged at an upstream position of the flow tube assembly and a second piezo element integrated with the outlet fitting is arranged at a downstream position of the flow tube assembly.
