Rapidly insertable central catheters (“RICC”) and methods thereof are disclosed. In an example, a RICC includes a catheter tube, a suture wing disposed over a medial portion of the catheter tube, a hub coupled to a proximal-end portion of the catheter tube, and a number of extension legs extending from the hub. The catheter tube can include a first section in a distal portion of the catheter tube formed of a first polymeric material having a first durometer. The catheter tube can also include a second section proximal of the first section of the catheter tube formed of a second polymeric material having a second durometer less than the first durometer. The catheter tube can have a column strength sufficient to prevent buckling of the catheter tube when inserted into an insertion site and advanced through a vasculature of a patient without use of the Seldinger technique.

Apparatus for puncturing a fossa ovalis includes a catheter shaped so as to define a central catheter lumen open through a catheter distal end opening. An angle between (i) a first line running between first and second lateral openings defined by the catheter and (ii) a second line that is parallel to a central longitudinal axis of the catheter when the catheter is straight, is between 30 and 150 degrees. A flexible longitudinal member passes (a) from a proximal portion of the catheter to a distal portion of the catheter, (b) out of the first lateral opening, and (c) into the second lateral opening, so as to form a loop outside the catheter. The flexible longitudinal member is configured to assume a deployment configuration in which a distal-most portion of the loop is curved and is distal to the catheter distal end opening. Other embodiments are also described.

The distal tip structure of a rapidly insertable central catheter (RICC) can be required to perform different functions from that of the remaining, multi-luminal section, of the RICC catheter. As such, the catheter body can be formed of a first material and the distal tip structure can be formed of a second material. Forming the RICC requires joining these two materials while maintaining a smooth abluminal surface. A bifurcated plug including a second material can be placed within a first lumen or second lumen of the catheter body. A mandrel can be placed within a third lumen. The assembly can then be placed within a die to plastically deform the bifurcated plug into a distal tip structure. Advantageously, only a single structure is required to plug the lumen and form the distal tip structure, reducing complexity and associated costs.

The invention relates to a calculus removal basket mechanism with a transparent film, and solves the technical problems of frequent instrument blockage and low calculus removal efficiency in a flexible ureteroscope and negative pressure sheath lithotripsy. The mechanism comprises a framework composed of a plurality of metal wires, a high-transparency film wrapping the periphery of the framework, an outer sleeve, a central guide pipe and a push-pull control device. The framework is automatically opened to form an umbrella-shaped or cup-shaped structure when being pushed out of the outer sleeve, and can be contained in a gap between the outer sleeve and the central guide pipe when being folded. In an operation, small stones are sucked out through the meshes under negative pressure, and large stones are taken out along with a lens after being intercepted by the film, so that synchronous operation of stone crushing and stone removing is realized. The high transparency of the film ensures that the surgical field is clear, the intrarenal pressure is stabilized in a safe range, and the risk of postoperative complications is remarkably reduced. The calculus removing device is simple in structure, convenient to operate, suitable for calculus of different parts such as renal pelvis and renal calyx, and high in efficiency and safety.

Furthermore, the total time required to place the catheter is reduced, thereby reducing patient downtime and improving patient outcomes.
