A medical syringe having a forwardly projecting needle that is selectively retractable following use and also having a specially configured plunger handle and thumb cap that cooperate to form a concave pressure application surface (“CPAS”). The concave pressure application surface at the rear of the plunger handle enables the subject medical syringe to achieve functional advantages, each with an associated therapeutic benefit, that are not achieved with use of the prior art devices.

An injection device is used for “tattooing” markers inside the heart of a patient at specific locations. Placement within the heart of markers, such as points marked with a radiopaque dye, may reduce the use of x-ray dye and echocardiography, may allow a quicker cardiac procedure, and thus may improve the procedure outcome for the patient. Alternatively or additionally to cardiac marking with a radiopaque dye, cardiac tissue fibrosis, cardiac tissue contraction, and/or cardiac tissue stiffening (or hardening) can be promoted at specific locations by delivering a suitable substance.

A hypodermic device is disclosed comprising a chamber, an array of hypodermic needles and a threaded Luer lock connector. The chamber comprises a distal outer surface and a proximal outer surface. The array of hypodermic needles projects outward from the distal outer surface of the chamber. Each hypodermic needle comprises a bore extending from a receiving end of the hypodermic needle to a delivery end of the hypodermic needle along a longitudinal axis. The bore in each of the hypodermic needles is in fluid communication with a hollow space in the chamber. The threaded Luer lock connector is in fluid communication with an opening at the proximal outer surface of the chamber. A first end of the threaded Luer lock connector is connected to the proximal outer surface of the chamber.

A sterile hydrogel composition that includes a crosslinked polymer, wherein the crosslinked polymer is an oxidation product of a thiol-modified hyaluronan and wherein the thiol-modified hyaluronan has a degree of modification of hyaluronan with thiol moieties of more than about 80 μmol per gram polymer, wherein the thiol-modified hyaluronan has a degree of modification of hyaluronan with thiol moieties of less than about 280 μmol per gram polymer, and wherein the thiol-modified hyaluronan has a mean molecular weight of at least 400 kDa.

A needle disk roller apparatus having a built-in pump, includes: a drug container (11) filled with a drug and having a built-in pump assembly (10); and a roller head (14) being able to interwork with the pump assembly (10), supplied with the drug by up-down pressing, configured to form holes in the skin using a plurality of needle disks (21) so that the drug penetrates into the skin, and having a drug base (16) that prevents the drug supplied from the pump assembly (10) from flowing down, and accumulates a predetermined amount of the drug inside an arcuate bottom (28) so that the drug is appropriately supplied to the needle disks 21 when the needle disks 21 are rotated.

A computerized electro-mechanical drug delivery device configured to deliver at least one dose of two or more medicaments. The device comprises a control unit. An electro-mechanical drive unit is operably coupled to the control unit and a primary reservoir for a first medicament and a secondary reservoir for a fluid agent, e.g. a second medicament. An operator interface is in communication with the control unit. A single dispense assembly is configured for fluid communication with the primary and the secondary reservoir. Activation of the operator panel sets a first dose from the primary reservoir and based on the first dose and a therapeutic dose profile, the control unit is configured to determine a dose or range of the fluid agent. Alternatively, the control unit determines or calculates a dose or range of a third medicament. Further, a dispense interface for use with a drug delivery device is disclosed.

The purpose of the present invention is to provide an injection needle and an injection device which are capable of adjusting the puncture depth of a needle. The present invention is equipped with: a needle; a needle base holding the needle such that the needle protrudes from the distal end side; and an adjuster provided on the outer periphery of the needle base so as to be movable in the axial direction of the needle base. By adjusting the axial-direction position of the adjuster, the protrusion length of the needle can be adjusted. Consequently, the puncture depth of the needle can be adjusted, and there is no need to prepare a plurality of type of injection needles having different protrusion lengths.

Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).

The present invention is directed to multi-liquid loading and delivery kits comprising a first storage vessel for a first active component, a second storage vessel for a second active component, at least two transfer syringes, at least two vial adaptors, at least two cannulas with a through lumen and a multi-liquid delivery device. The delivery device has dual hollow cartridges, each with at least one throughbore at one end and plunger access at the opposing end, a kick stand, a removable dual feed funnel, a spray or drip manifold and at least one spray or drip tip assembly.
