A catheter insertable into a cavity of a patient for monitoring pressure including a first lumen for drainage from the cavity and an expandable balloon. The balloon has a liquid containing chamber to monitor pressure within the cavity of the patient as pressure on the outer wall of the balloon deforms the balloon and compresses the liquid within the balloon. An exit port provides passage of air from an interior of the balloon to outside the catheter. A membrane has plurality of pores dimensioned to enable passage of air but prevent passage of the liquid therethrough. A pressure sensor communicates with the liquid containing chamber for measuring pressure based on compression of liquid caused by deformation of the expanded balloon.

The infusion lead assembly may form a fluid path to transmit fluid across the internal lumen, the connector needle, the infusion lumen, and the exit port.

A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

Disclosed herein are vascular access systems and methods thereof. For example, a vascular access system includes a port configured for subdermal implantation and a single-use access device. The port can include a port hub and a catheter tube. The port hub can include an access funnel and a septum defining a pair of port-hub lumens. The catheter tube can include a septum defining a pair of catheter-tube lumens fluidly coupled to the pair of port-hub lumens. The access device can include a bifurcated hub and a pair of cannulas. The pair of cannulas defines a pair of cannula lumens coupled to a pair of access device-hub lumens of the bifurcated hub. The pair of cannulas can be configured to simultaneously insert into the access funnel and couple the pair of cannula lumens to the pair of catheter-tube lumens when the pair of cannulas is fully seated in the port hub.

A bridge for facilitating delivery of reduced pressure to a wound site includes a reduced pressure lumen configured to be fluidly coupled to a reduced pressure source, a secondary pressure lumen configured to be fluidly coupled to a secondary pressure source, and one or more fluid adapters operable to be connected to a wound dressing disposed at the wound site. The one or more fluid adapters are positioned and configured with respect to the reduced pressure lumen to apply reduced pressure from the reduced pressure lumen to the wound site through the wound dressing and deliver exudate removed from the wound site through the reduced pressure lumen to the reduced pressure tubing. The secondary pressure lumen is fluidly coupled to the reduced pressure lumen to facilitate flow of the exudate removed from the wound site by the reduced pressure source using the secondary pressure source.

Disclosed is a hemostasis valve device including a connector including a first channel, a holder disposed at a first end of the connector and configured to communicate with the first channel, and a valve portion disposed at a second end of the connector and configured to selectively open or close the first channel. Here, the connector includes a first pipe including the first channel and a second pipe which diverges from a first point of the first pipe and includes a second channel configured to communicate with the first channel. Also, the first pipe includes a hole which allows the first channel to communicate with the outside. Here, the hemostasis valve device further includes an opening and closing portion disposed at the first pipe and configured to selectively open or close the hole. The hole is disposed between the first end and the first point.

The invention provides a drug mixing and injection system, in particular an adapter for said system enabling the preparation of drug formulations. In a first aspect, the invention relates to an adapter for a drug mixing and injection system comprising a first subunit (110) adapted to hold a vial (113) and a reservoir (115) with injectable liquid, a second subunit (120) comprising a valve (115) and an outlet port (122), at least one internal adapter channel (131), a first cannula (134) between the vial (113) and the internal adapter channel (131), wherein the adapter (100) has a resting position and an activated position. In another aspect, the invention relates to a drug mixing and injection system (200) comprising the adapter of the first aspect of the invention, a vial and a reservoir with injectable liquid. In a further aspect, the invention relates to a method of preparing an injectable drug formulation by use of the drug mixing and injection system (200) of the above mentioned aspect of the invention comprising activation of the system and transferring an injectable liquid from the reservoir to the vial, mixing the drug and transfer the resulting injectable drug formulation back to the reservoir, bringing the valve to a second position and transferring the injectable drug formulation to the outlet port.

Infusion systems and methods for administering an infusion fluid into a patients anatomic space at a variable flow rate without flow control include an administration set having a flexible tube fluidically connected to a needle connector, the needle connector including a receiving end fluidically connected to flexible tube, and an administering end opposite the receiving end and fluidically connected with an infusion needle, and the infusion needle having an inside diameter of about 0.0104 inches to about 0.0135 inches and fluidically connected to the administering end of the flexible tubing to deliver the infusion fluid to the patients anatomic space at variable flow rates dependent upon the saturation of the infusion fluid at the patients injection site.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a repeatable, aseptic fluid coupling system. Such repeatable, aseptic fluid coupling systems are configured to facilitate multiple connection and disconnection cycles while repeatably establishing a sterile fluid pathway through the coupling system. The repeatable, aseptic fluid coupling systems can repeatably establish a sterile fluid pathway through the coupling system even though the coupling system may be used in a non-sterile environment.
