An ambulatory infusing device including a housing, a reservoir defining an interior volume, a wall associated with the housing and having an inner surface that faces into the reservoir interior volume, and a filter assembly. The filter assembly may include a filter assembly housing with a housing filter portion having a free end associated with the inner surface of the wall and a filter supporting volume that extends to the free end of the housing filter portion, and a filter located within the filter supporting volume that extends to at least the free end of the housing filter portion.

An implantable system includes cells that produce and release a therapeutic agent, or agents, to a host in need. The system can include cells capable of eluting therapeutic agents in response to changing physiological conditions within a host. The system may comprise naked cells, encapsulated cells, or a mixture of non-encapsulating and encapsulated cells. The system may also comprise cells, and/or cell groups, of different origins. The implantable device may be placed intra-vascular, within bone marrow, within soft tissue, in the peritoneal cavity, or intra-hepatic, etc. The system can be comprised of a stent, or like devices. Such stents and like devices may optionally include port(s), catheter(s), and containment envelope systems for holding the above cells.

A flow metering insert (10) for a drip chamber (50) is provided that is suitable for use in intravenous administration. The insert comprises: a primary liquid flow channel with an inlet, an outlet, and a flow-resistant passage between the inlet and the outlet; and a flow indicating channel in communication with the primary liquid flow channel between the inlet and the flow-resistant passage. The flow-resistant passage provides a resistance to liquid flow such that liquid is forced into the flow indicating channel and reaches a height proportional to the rate of liquid flow through the primary liquid flow channel. The flow-resistant passage and the flow indicating channel are at least partially defined by one or more first recesses and/or channels in the insert such that the flow-resistant passage and the flow indicating channel are formed between the insert and a wall of the drip chamber when the insert is inserted into the drip chamber.

A syringe with a filter is disclosed. When liquid medicine for treatment such as an analgesic is suctioned into the syringe by using a syringe needle and then injected into a human body through the syringe needle, foreign substances generated in an ampule and the like are filtered in the syringe prior to the liquid medicine being injected into the human body as the foreign substances are suctioned into the syringe through the syringe needle. In addition, the filter is configured so that the filter can be installed into the syringe with ease.
