International Classification:

A61B 17/20

US Classification:

604 47

Abstract:

An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. A device includes a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. The dermal-access member extends at least 1 mm from the protrusion. A mechanism drives the device against the skin at a calculated speed of about 6 m/s to about 18 m/s.

International Classification:

A61K 9/22

US Classification:

6048901, 6048911, 604134

Abstract:

A fluid delivery device for delivering a substance to a patient by way of infusion delivers the preparation at a rate of flow which varies in steps from a substantially constant higher rate, to a stepped-down substantially constant lower rate or rates. The delivery device includes one or more reservoirs, and one or more Belleville springs for applying generally constant pressures to the substance contained in the reservoirs. Each reservoir will have a different constant pressure applied in a mid-range of operation. The reservoirs can be interconnected to each other and to an infusion device in a number of arrangements, including various manifolds and flow restrictors, such that the rate of flow is controlled in steps in accordance with the pressures applied by the springs of the plurality of reservoirs.

International Classification:

A61M 5/20

US Classification:

604134

Abstract:

A system and method for a patch-like, self-contained substance infusion device which provides one or more substantially hidden patient needles which can be placed in fluid communication with a fluid reservoir subassembly that includes a rigid bladder portion used in conjunction with a non-distensible bladder film, such as a metallized film. Simple removal of an interlock allows a disk, or Belleville spring assembly to apply an essentially even and constant pressure to the contents of the fluid reservoir assembly, and allows the device to then be attached to a skin surface via an adhesive contact surface. A push button activation assembly is provided which can then be used to release and seat one or more spring-loaded patient needles into the skin surface, and establish a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin.

US Classification:

604165030, 264255000, 264328100

Abstract:

Various single-part catheter assemblies, multi-part integrated catheter assemblies, and methods and apparatus for making the same are disclosed. The single-part catheter assemblies include a catheter hub integrally formed with a catheter tube for insertion into the bloodstream of a patient. The multi-part integrated catheter assemblies include a catheter hub integrally formed to a catheter tube for insertion into the bloodstream of a patient. The catheter assemblies of the invention may be injection molded in a single step or in multiple steps by injecting flows of molten plastic into a cavity of molds provided herein such that the flows converge into an even distribution about the circumference of the sleeve. The mold may have a core pin designed to fit into the cavity. Through the use of the even distribution of flows, the core pin may be seated within the cavity in an untensioned manner. The catheter assemblies of the invention may be produced of a single material or of multiple materials.
