A urine-sampling system for aseptic urine sampling includes a catheter assembly and a sampling-port access device. The catheter assembly includes a urinary catheter, drainage tubing, and a connector fluidly connecting the urinary catheter to the drainage tubing. The connector includes a urine-sampling port. The sampling-port access device includes a tip at an end of a barrel configured to fluidly connect the sampling-port access device to the urine-sampling port of the catheter assembly. Each of the tip of the sampling-port access device and the urine-sampling port has a complementary fastening means forfastening to the other of the tip of the sampling-port access device and the urine-sampling port. Each of the complementary fastening means ensures proper mating of the tip of the sampling-port access device and the urine-sampling port for aseptic urine sampling. In addition to various urine-sampling systems such as the foregoing, methods of use are also disclosed.

The present embodiments provide strain relief members for a medical device delivery system, methods of use, and methods of manufacturing. In one embodiment, a medical device delivery system may include a body member with a first end having a first outer diameter, a second end having a second outer diameter, an inner surface facing a lumen that extends axially through the body member along a longitudinal axis, and an outer surface opposite to the inner surface. The embodiment also includes a threaded first connector at the first end of the body member. The outer surface of the body member may include a plurality of depressions. The body member may include a first material. The first connector may include a second material. The first material is more flexible than the second material. A portion of the outer surface of the body member may cover a portion of the first connector.

A catheter assembly includes a flexible catheter having a lumen, a hub having a body including a proximal end and a distal end, the body defining a passageway extending from the proximal end to the distal end, the hub being coupled to one end of the catheter, and the passageway of the hub being in fluid communication with the lumen of the catheter, and a coupler including a base coupleable to and detachable from the hub, the base being coupled to at least one introducer assembly, each of the at least one introducer assembly including a port, a tubing and a hollow needle.

A hub defines a lumen with a longitudinal axis along the length of the hub. An outer surface of a distal portion of the hub tapers inwardly toward the longitudinal axis as the distal portion extends distally. A strain relief includes a proximal portion configured to receive the distal portion of the hub. The strain relief defines a lumen that substantially aligns with the hub lumen when the proximal portion receives the hub. The hub and/or strain relief are configured to be fixedly attached to a catheter body such that a catheter body lumen substantially aligns with the hub lumen and the strain relief lumen when the strain relief receives the distal portion of the hub. Outer surfaces of the strain relief and hub define substantially similar distances to the longitudinal axis along an interface between the two outer surfaces when the strain relief receives the hub.

A method of making a medical device includes holding a spacer tool by a slot of a mold, and accommodating a portion of a first tube by a lumen in the spacer tool, wherein a region of the first tube is inside the mold cavity and outside the spacer tool, and an end of the first tube is in engagement with an end of a first lumen-defining section of a first core pin. The spacer tool includes a first section located in the mold cavity when the spacer tool is held by the slot of the mold, the first section of the spacer tool being configured to define a cavity to be formed circumferentially around a part of the first tube inside a hub to be formed, wherein the part of the first tube is different from the region of the first tube.

A medical device, includes: a first tube with a first tube lumen; a second tube with a second tube lumen, wherein the second tube is disposed around the first tube; and a hub comprising a first port, a second port, a first lumen, and a second lumen, the first lumen extending from the first port and being in fluid communication with the first tube lumen of the first tube, the second lumen extending from the second port and being in fluid communication with a cavity within the hub; wherein the hub is made from a material, and wherein the cavity is defined by the material of the hub, and is in fluid communication with a space between the first tube and the second tube.

A mold system for making a medical device includes a mold having a mold cavity for receiving a material; first and second core pins, each having a first lumen-defining section located, or otherwise configured for placement, in the mold cavity; and a spacer tool having a lumen sized for accommodating a first tube that is in a fixed position with respect to the mold, wherein a first end of the first tube is engaged with the first lumen-defining section of the first core pin, and wherein the spacer tool comprises a first section configured for placement in the mold cavity of the mold, the first section of the spacer tool having a first outer cross-sectional dimension that is larger than an outer cross-sectional dimension of the first tube.

Needle devices having a component that provides the function of fixing a valve in a standard diameter sized catheter hub, the valve and/or the component provide or provides a proximally directed axial force for returning the valve opener from a distal position within the catheter hub to a proximal position within the catheter hub when a male Luer is disconnected from the catheter hub. Various components can be located inside a single hub body catheter hub that can restrict fluid flow, allow actuation to permit fluid flow, prevent needlestick injuries, and combinations thereof.

Aspects of the present invention relate to a medical tube for delivering nutrients or medication to a patient. The tube comprises a flexible tubular body for conveying the nutrients or medication to the patient and a small-bore connector for connecting the medical tube to a syringe or pump. The small-bore connector is secured to the tubular body by an overmoulded component that encapsulates a portion of the tubular body and a portion of the connector thereby securing the connector relative to the tubular body of the medical tube.

Helically winding an extruded web to form a wall of a heated hose about a central axis, extruding a bead of plastics material around a heating wire such that the extruded bead comprises the heating wire at a first location within a cross-section of the extruded bead, helically winding the extruded bead onto the wall of the hose to provide a support helix, and exerting tension on the heating wire to draw down the heating wire toward the central axis such that the heating wire migrates radially inward from the first location to a second location within the cross-section of the extruded bead.
