A rigidizing device includes a plurality of layers and an inlet between the elongate flexible tube and the outer layer and configured to attach to a source of vacuum or pressure. The rigidizing device is configured to have a rigid configuration when vacuum or pressure is applied through the inlet and a flexible configuration when vacuum or pressure is not applied through the inlet.

A strain relief adapter (100) for a medicament delivery device (200) includes a flexible body (101) having a first end (102) configured to connect to one of a fluid connector and a pump connector, a second end (104) configured to connect to tubing, a hollow fluid path (108, 110, 112, 114) therethrough fluidly connecting the first and second ends, and a plurality of external strain relief ridges (106) disposed between the first and second ends.

A flow restriction device may include a male luer connector portion, a female luer connector portion disposed proximally to the male luer connector portion, and a body portion extending between the male and female luer portions, and integrally formed with the male and female luer portions to form a single monolithic piece. The male luer connector portion may have an internal surface defining a lumen thereof, and the female luer connector portion may have an internal surface defining a lumen fluidly connected to the lumen of the male luer connector portion. The body portion may have a recess extending longitudinally therethrough and fluidly communicated with the lumens of the male luer portion and the female luer portion. The recess may define a micro-channel along which fluid flows from the male luer connector portion into the fluid collection device via the female luer connector portion.

The invention relates to a device for connecting multi-lumen lines for the medical field, in particular for wound care in the field of vacuum therapy, having a preferably one-piece basic body, designed for tight and preferably releasable connection of at least two line lumens, wherein the basic body, for furnishing a distributor chamber for at least one, preferably two, three, or more lumens, opening into it, of the connected line and preferably at least one channel for removing a fluid from and introducing it into the distributor chamber, and when the line is connected, the distributor chamber is sealed off in fluid-tight fashion from at least one line lumen in such a way that a fluid exchange between the distributor chamber and this line lumen is prevented.

An instrument connection device having a flexible hose-like body with a flexible wall in which the proximal end of a hose is inserted. The hose has a lumen that extends longitudinally through the hose. A wire is arranged inside the hose, for example, inside the lumen. The wire is guided through a punctured hole in the wall that the wire may create during a penetration of wall. The punctured hole may be straight and guides the obliquely. For example, the hole may be inclined to the radial axis and the longitudinal center axis.

A method of delivering a therapeutic substance for treatment to a region of the body through vascular isolation and manipulation of fluid flux into and from the region of the body including the steps of: restricting vascular inflow to the region of the body; washing out oncotically active plasma proteins from the region of the body by increasing the outward oncotic pressure gradient from the region of the body; inducing ischemia in the region of the body; controlling the pressure and fluid flow of the main blood vessels to and from the region of the body; providing the therapeutic substance to the region of the body when the fluid flow to the region of the body is controlled.
