In accordance with some configurations, systems and methods for guided removal from an in vivo subject are provided. In some configurations, a method for removing an object is provided. The method comprising, guiding a flexible tube through a passageway of an in vivo subject, wherein the flexible tube comprises at least a first passageway and a second passageway. Positioning a distal end of the first passageway in proximity to the object. Infusing liquid through the second passageway substantially continuously. Removing the object through the first passageway with at least a portion of the liquid while suction is not being provided.

A catheter holder includes an attachment section configured to be attachable to a holder tube that accommodates at least a portion of a sheath of an image diagnosis catheter in a wound state, a support section extending from the attachment section in a direction away from the wound holder tube, and a fixing section provided on a second end side of the support section, which is opposite to a first end side of the support section on which the attachment section is provided, and configured to fix a unit connector and a hub of the image diagnosis catheter to hold the outer tube, which is exposed from an opening portion of the holder tube, in a linear shape to be fixed in position.

A valve and a method for administering a plurality of drug fluids to a patient are disclosed. For each drug fluid, the valve may be rotated into a selected drug position associated with the drug fluid. With the valve being in the selected drug position, a backpriming may be performed of a connector line of a drug container containing the drug fluid. Thereafter, the drug fluid may be administered with the valve being in the same selected drug position. Thereafter, the valve may be flushed, optionally while maintaining the same selected valve position.

Various aspects of the subject disclosure relate to a compounder system having a cartridge that includes controllable fluid pathways. One or more rotary piston pump/valves may be used to move fluid and/or gasses through the various fluid pathways of the cartridge. For example, the cartridge may include a dedicated rotary piston pump/valve for each process that moves fluid and/or gas through the cartridge. When turning, the rotary piston pump/valve acts as a pump to move the fluid or gas, and when the rotary piston pump/valve stops turning, it effectively acts as a shutoff valve, preventing any fluid flow. Magnetic couplers for the cartridge may be provided on a pump head of the compounder system.

A connecting device for a medical infusion system includes a connection piece which has a connecting profile for the connection of a functional part of the infusion system. The connecting device also has a resiliently flexible, cup-like valve body which is arranged in the connection piece and has a valve casing and cap-shaped top region which is provided with a slit arrangement. Further, the connecting device has a dimensionally stable base portion on which a base ring of the valve casing is supported and which is firmly connected to the connection piece. In the unloaded initial state, the valve casing has a convex internal contour which, starting from the cap-shaped top region, first expands in the direction of the base ring and subsequently narrows again, forming an O-like internal longitudinal section. The connecting device can be in the form of a three-way stopcock for an infusion system.

A medical device according to the disclosure includes: two members that are made of materials having different flexural moduli and are connected to each other, in which a soft member made of a material having a low flexural modulus of the two members includes a cylindrical portion, a hard member made of a material having a high flexural modulus of the two members includes a cylindrical support portion that supports the cylindrical portion, and the cylindrical support portion includes an inner surface support portion that supports an inner surface of the cylindrical portion, and an outer surface support portion that supports an outer surface of the cylindrical portion.

A device is provided for shielding a fluid access port structure that is located along tubing that is part of an intravenous (IV) medication delivery system and is configured to permit injection of a fluid into the tubing. The device includes a body having a hollow interior and a first opening formed therein for receiving the fluid access port structure such that a side wall of the body surrounds and extends above the fluid access port structure. The body also includes a second opening through which a fluid delivery member can be inserted to allow mating between the fluid delivery member and the fluid access port structure for delivering the fluid into the tubing.

Proposed is a stopcock that enables natural injection of a drug and prevents backflow of a drug injected in another direction on a body. The stopcock includes: a body formed in a passage shape connecting a drug solution injection pipe and a supply pipe to each other; and a backflow prevention unit having a first end coupled to a side of the body between the drug solution injection pipe and the supply pipe and a second end extending toward an inside of the body to isolate the drug solution injection pipe and the supply pipe from each other, in which the second end of the backflow prevention unit bends toward the inside of the body and guides movement of a drug when the drug is injected through the drug solution injection pipe, and elastically moves to an initial position when injection of the drug is stopped.

An exemplary compounding system and method can include two pump heads for simultaneously drawing two different fluids from at least two separate input containers such that the at least two different fluids are mixed and distributed to an output container. The system can include a manifold that maintains separation of certain of the different fluids until after passing by a first pump and a second pump and/or additional pumps. A junction can be placed in the fluid line downstream of the first and second pumps and/or additional pumps such that all or some of the fluids are mixed prior to output to the output container. The method of using the system can include incorporating software that selects various fluids at certain times and sequences to ensure optimum efficiency and safety for the system, and can continue compounding actions even when an input supply container runs out or otherwise fails to supply a particular fluid/material. The method of use also includes connection of a transfer set to a housing in a manner that further ensures optimum efficiency and safety.

A system for delivering an implantable medical device to an implant location includes a control handle portion, a catheter portion coupled to the control handle portion, and a distal portion configured to receive the implantable medical device. The catheter portion includes outer shaft including an inner braided layer extending axially along the outer shaft, an outer braided layer extending axially along the outer shaft, wherein the outer braided layer has a lower density of braids relative to the inner braided layer, and an axial spine positioned between the inner braided layer and the outer braided layer extending axially along the outer shaft.
