Abstract: Examples of catheter devices, removable needle devices and kits are disclosed. Also methods for accessing a hollow organ are disclosed. The catheter devices include a body extending longitudinally from a proximal end to a distal end, wherein the body includes an elongated channel along a longitudinal length of the body extending from the proximal end to the distal end of the body, wherein the elongated channel is configured to receive an elongated needle of the removable needle device, and the body includes one or more cutting edges extending in a proximal direction from the distal end of the body. The body of the catheter devices includes one or more recesses adapted to mate with one or more catches of the removable needle device for coupling the needle device to the catheter device. Methods of using the catheters, removable needle devices and the kits are also disclosed.

Abstract: The present disclosure relates to a container for the production of a foamed sclerosant composition, to kits and systems including such a container, to methods for preparing a foamed sclerosant composition using such containers, and to a foamed sclerosant compositions obtainable by such methods. In an aspect, the container comprises a container body and a mixing element disposed in the container body, such that a foaming space is defined in an interior of the container body between the sidewalls and the mixing element. The mixing element may be configured to be operatively coupled with a rotating actuator without the actuator reaching the foaming space.

Abstract: A catheter device configured to provide access to a hollow organ is provided. It includes a body extending longitudinally from a proximal end to a distal end and a flexible insertion tube extending longitudinally from a proximal end to a distal end, wherein the body includes an elongated channel along the longitudinal length of the body extending from the proximal end of the body to the distal end of the body, wherein the channel is configured to receive an elongate needle. The body further comprises one or more cutting edges extending rearwardly from a distal end of the body. Furthermore, the flexible insertion tube of the catheter device is coupled to the distal end of the body and comprises a tubular elongated passage aligned with the tubular elongated channel of the body forming a lumen. Kits including such catheter devices and methods for accessing a hollow organ are also provided.
