Abstract: A proximally trimmable catheter is disclosed. In one embodiment, the catheter includes a multi-lumen catheter tube, one or more extension tubes, and a hub for fluidly connecting the two. In a first unlocked state, the hub is axially slidable along the catheter tube. The hub includes tube pins that are in fluid communication with the extension tubes. A cutting member is positioned to longitudinally cut the catheter tube during axial sliding of the hub along the catheter tube such that distal portions of the tube pins remain disposed within the lumens of the catheter tube. When positioned as desired, the hub is locked into a second locked state and is no longer axially slidable along the catheter tube. The tube pins are fluidly sealed within the lumens of the catheter tube as to establish fluid communication between the extension tubes and the lumens via the tube pins.

Abstract: A dilator system for insertion of a catheter or other elongate device into a body of a patient includes a catheter having a lumen that initially defines a first inner diameter. The catheter includes a swellable material that swells after insertion into the body. A dilator includes an elongate body that is initially disposed in the catheter lumen and a tapered head extending from a distal end of the catheter lumen. The dilator head defines an outer diameter that is larger than the first inner diameter of the catheter lumen. After insertion of the dilator head and a distal portion of the catheter into the body, the catheter swells such that the lumen defines a second inner diameter that is larger than the outer diameter of the dilator head. This enables the dilator to be proximally removed from the body via the catheter lumen defining the second diameter.

Abstract: A bi-directional valve assembly, including valves for use in closed-ended catheters or other elongate tubular devices, is disclosed. In one embodiment, a catheter assembly for insertion into a body of a patient is disclosed and comprises an elongate catheter tube including an outer wall that at least partially defines at least one lumen that extends between a proximal end and a closed distal end thereof. The catheter tube includes a valve assembly that in turn includes a linear slit valve defined through the outer wall of a distal segment of the catheter tube, and a deformation region.
