The present invention discloses a flexible digital ureteroscope that is at least partially disposable. The ureteroscope comprises a single-use catheter and a handle. The catheter comprises a distal end, a bend portion, and a proximal portion. The distal end has a rigid or semi-rigid shell that houses a set of micro lenses, an image sensor microchip, and a plurality of LED light sources. A working channel extends along the entire catheter and is coupled to a working channel port on the handle to receive various medical devices and irrigation lines during an endoscopic procedure. In addition, the catheter includes one or more steering wires to control the distal end to bend towards a desired direction. The rigid or semi-rigid shell of the distal end is made of a mix of polymer composite material with graphene nano-filler for enhancing thermal dissipation. The handle may be a single-use handle or a reusable handle. In case the handle is a reusable handle, it includes a battery module and a wireless communication module for communicating with a host machine wirelessly. In case the handle is a single-use handle, to reduce cost, the handle does not include a battery module and/or a wireless communication module. Rather, the single-use handle includes a host interface for receiving power from the host machine and transmits image data to the host machine.

The present invention relates to a multi-reservoir port, catheter, and non-coring needle system that supports high-flow applications such as hemodialysis and apheresis. In particular, the invention relates to improvements to provide optimal flow rates, septum life, and septum/needle stability when introducing fluid into the multi-reservoir port.

An elastomer molded body for a medical device includes an elastomer portion and a filler. The elastomer portion contains a crosslinked fluorine-based elastomer. The filler is formed from a plurality of particles each of which has aspect ratio of 5 or more and specific surface area of 3 m.sup.2/g or more and 10 m.sup.2/g or less. The aspect ratio is defined as a ratio of a dimension in a long axis direction thereof to a dimension in a short axis direction thereof. The filler has an uneven distribution in a surface layer part of the elastomer portion and is oriented in a direction along a surface of the elastomer molded body.

A medical device for insertion into a natural or artificial body opening, such as a urinary catheter is described. The medical device comprises a substrate having a wall enclosing an internal cavity that forms a tubular body. The wall extends between a proximal insertion end and a distal rearward end. The wall comprises at least 30 wt % of natural fibers, such as cellulose fibers. One example medical device is, at least to a large extent, made of paper.

Tubing, such as medical tubing for administration of intravenous fluid, can include an outer layer on an inner layer, and, optionally additional layers, in which at least the outer layer and the inner layer are made of a same polymeric material but the outer and inner layers have differing amounts or differing types of a plasticizer such that a hardness of the outer layer is greater than a hardness of the inner layer.

Embodiments of the invention include devices and coatings for devices including coated hydrophobic active agent particles. In an embodiment, the invention includes a drug delivery device including a substrate; and coated therapeutic agent particles disposed on the substrate, the coated therapeutic agent particles comprising a particulate hydrophobic therapeutic agent; and a cationic agent in contact with the particulate hydrophobic therapeutic agent. Other embodiments are also included herein.

Embodiments include a catheter comprising a proximal handle, a distal tip, and a shaft extending between the proximal handle and the distal tip. The shaft comprises an outer polymer layer, and an inner polymer layer disposed adjacent to the outer polymer layer and defining an internal lumen. The inner polymer layer includes a blend of two or more polymers, and the blend of two or more polymers includes PTFE and one or more copolymers.
