摘要： Catheter systems including one or more flow restrictors are disclosed. The catheter systems may include two or more delivery branches. The delivery branches may be connected to a supply catheter section using a branching catheter connector that may include one or more flow restrictors. The flow restrictors may include a restrictor body located within a lumen with a channel located between the restrictor body and interior surface of the lumen, the channel restricting flow through the lumen past the flow restrictor. The channel may be defined by a groove formed in the restrictor body and/or the interior surface of the lumen. Methods of providing pressure relief by flowing fluid past a flow restrictor are also disclosed.

摘要： A human body implantable drug delivery pump has a housing including at least a first shield and a second shield. The housing defines an interior within the shields. The pump further includes a fluid reservoir within the housing, a fluid conduit also within the housing from the reservoir, an outlet from the fluid conduit to the exterior of the housing, and a pump member in the housing adapted to move fluid through the fluid conduit to the outlet. The fluid in the reservoir and fluid conduit is isolated from the pump interior. The pump further has a desiccant in the pump interior, the desiccant absorbent of moisture in the pump interior, and preferably absorbent of substantially all the moisture in the pump interior. The desiccant also preferably has a moisture absorbent property dependent on temperature, being lessened at higher temperatures, the desiccant being pre-baked to improve its moisture absorbent property before being placed in the pump.

摘要： The displacement of refill valves in an implantable drug delivery device is reduced to permit the housings of a drug delivery device to remain compact in size while permitting reservoirs of increased depth to be used. In a preferred embodiment, a collapsible link is provided as a telescoping member incorporating a coil spring. As the valve is pulled into contact with its seat, a detectable pressure increase is sensed in the refill device. In accordance with the invention, as the drug supply contained in the reservoir depletes, the reservoir surface moves towards a collapsed position, compressing the coil spring and eventually contacting the valve stem, thereby lifting the valve from its seat. By virtue of telescoping link, the valve stem length and therefore the valve travel may be reduced as compared to prior art devices, thus eliminating the need for increased housing depth when deeper reservoirs are used. The collapsible link may be comprised of a second spring combined with a telescoping link. The second spring is situated on a side of the valve opposite the telescoping link, thereby providing a downward force on the valve and valve stem. As an other alternative, the invention provides a lever arm for actuating the refill valve. A pivot for the lever arm is situated near the refill valve and a distal end of the lever arm maintained in contact with the reservoir surface using a spring bias. An intermediate portion of the lever arm engages the valve stem. Thus, as the reservoir surface moves towards the collapsed position, the displacement of the valve is a fraction of the displacement of the distal end of the lever arm.

摘要： An implantable lead has a lead body construction designed to accommodate loading forces exerted on the lead body during patient movement. The lead body is sufficiently stretchable to resist forces that could otherwise cause lead failure, axial migration of the electrodes, anchor damage, or tissue damage. The lead body may include a variety of features that reduce the axial stiffness of the lead without significantly impacting the operation and structural integrity of lead components, such as electrodes, conductors and insulators.

摘要： An implantable lead has a lead body construction designed to accommodate loading forces exerted on the lead body during patient movement. The lead body may be sufficiently stretchable to resist forces that could otherwise cause lead failure, axial migration of the electrodes, anchor damage, or tissue damage. Increasing stretchability of a lead body can also increase the vulnerability of the lead body to flex fatigue, buckling fatigue, kinking, and crush. Therefore, the lead described herein includes a reinforcement to create a lead body that is resistant to flex fatigue, buckling fatigue, kinking and crush.

摘要： Low profile inlet valve embodiments for a piston pump therapeutic substance infusion device are disclosed that reduce dead volume, occupies little residential space, operates rapidly, and have many other improvements. The therapeutic substance infusion device has a housing, a therapeutic substance reservoir, a power source carried in the housing, electronics, a piston pump, and an inlet valve. The piston pump is configured for pumping therapeutic substance from the therapeutic substance reservoir through an infusion port at a programmed rate. The inlet valve is in fluid communication with a reservoir outlet to control the flow of therapeutic substance into the piston pump. The inlet valve has a substantially coplanar valve surface and valve spring. Many embodiments of the low profile inlet valve and its methods of operation are possible.

摘要： A pressure-sensitive overfill protection system for a refillable drug delivery device includes a collapsible link which, in a preferred embodiment, comprises an aneroid having an internal volume of gas at a reference pressure. The collapsible link, in its expanded state, supports on inlet valve in an open position to permit the ingress of new drug fluid into a bellows reservoir. The external surface of the aneroid is exposed to the bellows pressure. When the bellows pressure exceeds the reference pressure, the aneroid collapses and permits the inlet valve to move to a closed position under a biasing force provided by a spring. Further flow of new drug fluid into the drug delivery device is thereby prevented. Moreover, the closure of the valve provides a large increase in pressure is experienced in the refill device and may therefore be sensed by a clinician. Because the overfill protection system is pressure sensitive, it may be used with different sized bellows without modification.
