Abstract: 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.

Abstract: A method involves selecting a type of cell for implantation into a mammal and identifying the specific gravity or density of the cell type. Then, a carrier liquid is selected which has a specific gravity or density within a range of specific gravities or densities which approximately matches the specific gravity or density of the selected cell type. A liquid for delivery of growth cells into tissue of a mammal is also provided in which the density of a carrier fluid component is matched to the density of the cells being consistently delivered by the carrier fluid.

Abstract: An implantable electrode type lead assembly 10 of the flexible type which is particularly adapted for implantation in the cardiac tissue for applications such as use with a pacemaker. The lead assembly has an electrode head 40 which includes a fixation spiral for implantation into tissue. The spiral or rotation action of the electrode head 40 is controlled by means of an elongated torsionally wound electrical coil conductor 14, the coil extending through the lead from the proximal to the distal end thereof and carried within a silicone tube 24 which is co-extensive therewith, the tube having been especially treated to modify the slip characteristics of the internal diameter (ID) thereof for high efficiency torque transfer.

Abstract: A medical catheter comprising a flexible tube having an outer wall and an inner wall, the inner wall defining a lumen, the lumen extending longitudinally along the flexible tube and having a cross-sectional area; and a flexible core within the lumen substantially extending longitudinally along the flexible tube, the flexible core having a cross-sectional area smaller than the cross-sectional area of the lumen at any given longitudinal point along the flexible tube and flexible core, the flexible tube and the flexible core defining a passageway, and which in combination provides structure resistant to occlusion of the passageway.

Abstract: A medical catheter comprising a proximal end having an opening for fluid containing a therapeutic drug, a distal end, the distal end defining at least one opening, and a porous portion covering the opening defined by the distal end. In one embodiment, the medical catheter comprises a proximal end having an opening for fluid containing a therapeutic drug, at least two distal ends, the proximal end connected to the two distal ends with a connector, the distal ends each defining at least one opening, a diffuser covering the opening of each distal end, and a separate restrictor downstream of the connector and upstream of each distal end to provide substantially equal flow through each distal end. An additional restrictor can also be placed upstream of the connector. In another embodiment, a combination diffuser and restrictor covers the opening of each distal end.
