An intraosseous needle includes a cylindrical shaft. The cylindrical shaft includes a first portion comprising a plurality of threads protruding from the cylindrical shaft. The cylindrical shaft includes a second portion comprising a plurality of fenestrations, disposed between the first portion and a distal end of the cylindrical shaft, wherein the cylindrical shaft is continuous and smooth within the second portion, and where the continuous, smooth second portion is longer than the first portion. The intraosseous needle also includes a needle head extending from a proximal end of the cylindrical shaft.

An intraosseous needle assembly includes a needle having a first cylindrical shaft. The shaft having a distal end, a proximal end, and a wall defining an inner channel. The first cylindrical shaft includes threading protruding from the wall along a proximal portion of the first cylindrical shaft. The needle further includes a needle head extending from the proximal end of the first cylindrical shaft. The needle assembly may further include a stylet, the stylet having a second cylindrical shaft having a first end and a second end and a stylet head extending from the second end. The stylet head includes a proximal surface and a distal surface, a pair of substantially parallel second side walls, a pair of rounded end sections joining the second side walls, a protrusion extending from the distal surface, and a tapered section extending from the distal surface to the second cylindrical shaft.

A multiple pen needle or syringe needle storage and dispensing system where a plurality of needle devices such as pen needles including a cover can be disposed on strip, where the strip serves a seal for multiple needle devices. Each needle device can be peeled off the strip unsealed for immediate use for example in an injections device, or separated from the strip sealed for later use.

Disclosed embodiments include apparatuses and methods for using a tip member to deposit or collect a supply of material from within a body. In an illustrative embodiment, an apparatus includes a tip body defining an annular chamber. A tip receptacle is configured to be joinable with a lumen and to receive a fluid flow therethrough and to convey the fluid flow into the annular chamber. A material distribution element is fluidly coupled with the annular chamber, wherein when the fluid flow is introduced into the annular chamber. The material distribution element diffusively passes the fluid flow out of multiple egress points in at least one of a distal end and a lateral surface of the tip body.

Disclosed herein is a syringe device comprises (a) an outer housing, (b) a barrel, (c) a stopper, and (d) a plunger with one or more grooves.

A delivery system for delivering a drug depot to a site within a patient, the system comprising: a cannula; a delivery stylet configured and dimensioned to be receivable by and slidable forwardly and backwardly within the cannula including to a position wherein a distal portion of the stylet protrudes beyond the distal end of the cannula; a drug depot retainable by the stylet at the distal end of the stylet, the drug depot being visualizable by a diagnostic imaging beam or modality; and an actuator for ejecting the drug depot from the stylet to a site within the body using fluid pressure. Also disclosed are methods using, and uses of, the delivery system, including for treating scoliosis.

A drug delivery system is provided that has an adjustable dose mechanism allowing setting and locking the dose then administration of the set dose. A method for administering a medicament using the drug delivery system is also provided.

Provided are devices and methods for injecting viable transplant tissues into a subject. The device includes a fluid exchange chamber having a funneled portion connected to a pre-injection tube. The chamber includes fluid transfer holes and is disposed in an outer shell having a central bore connecting a top inlet and a bottom outlet from which the pre-injection tube exits the shell. A plunger having a central channel and a tapered bottom is disposed in the central bore such that the tapered bottom mates the funneled bottom when depressed and a stylet plunger is disposed in the central channel of the plunger.

the present invention provides a needle system comprising a needle assembly (1, 100, 200, 300) and a drug cartridge (30, 130, 230, 330), the needle assembly (1, 100, 200, 300) comprising a needle hub member (4.1, 104.1, 204.1, 304.1) in which an injection needle (15, 115, 215, 315) is fixedly mounted such that a front needle portion (15f, 115f, 215f, 315f) extends in a distal direction therefrom and a rear needle portion (15r, 115r, 215r, 315r) extends in a proximal direction therefrom, and a skirt member (4.2, 104.2, 204.2, 304.2) extending proximally from the needle hub member (4.1, 104.1, 204.1, 304.1) and defining a skirt cavity (4.9, 104.9, 204.9, 304.9) accommodating the rear needle portion (15r, 115r, 215r, 315r), the skirt cavity (4.9, 104.9, 204.9, 304.9) having a skirt cavity configuration, and the drug cartridge (30, 130, 230, 330) comprising a generally cylindrical body (31, 131, 231, 331) being sealed proximally by a slidable piston (239, 339) and having an outlet end portion defined by a neck (32, 132, 232, 332) and a head (33, 133, 233, 333), the head (33, 133, 233, 333) having a head configuration, wherein the skirt cavity configuration corresponds to the head configuration, providing for a tight fitting of the skirt member (4.2, 104.2, 204.2, 304.2) on the head (33, 133, 233, 333) which renders the rear needle portion (15r, 115r, 215r, 315r) a permanent resident of the outlet end portion.
