A cannula comprising a hollow tube made of a biocompatible, thermoplastic polymer, memory shape material, tipped with an injection needle or an electrode at it distal end, assumes desired shapes as it distally emerges from a lumen or channel of an instrument such as an introducer or endoscope. The desires shapes include a curvature conforming to an inverse tangent function. The cannula may be supplied alone, with or without an injection needle or electrode, and in a sterile pouch, for use with a device of a user's choice that has a suitable lumen or channel to guide the cannula, of the cannula may be used without such an instrument. The injection needle can be shorter than conventional to thereby inject medication only or primarily in submucosa and can be sharpened only or mostly at it distal end while the remaining portion of a bevel is not sharp, to thereby reduce the size of an opening the needle makes in tissue and helps keep the medication from leaking out of the injection site.

Endoscopic cannula

A cannula comprising a hollow tube made of a biocompatible, thermoplastic polymer, memory shape material, tipped with an injection needle at it distal end, assumes desired shapes as it distally emerges from a lumen or channel of an instrument such as an introducer or endoscope. The desires shape includes a curvature conforming to an inverse tangent function. The cannula may be supplied alone, with or without an injection needle, and in a sterile pouch, for use with a device of an user's choice that has a suitable lumen or channel to guide the cannula, of the cannula may be used without such an instrument.

An incremental syringe is provided and includes a syringe barrel, a finger grip disposed at the proximal end of the syringe barrel, a tab disposed inside the syringe barrel, and a plunger body having detents, wherein the detents are configured to interact with the tab to provide audible and tactile feedback to a user when the plunger body is pushed through the syringe barrel in a distal direction.

Incremental syringe

A medical injection assembly is provided and includes an introducer with a handle, a sheath, a scope lumen configured to receive an endoscope at a first proximal end of the handle and hold the endoscope in a desired position, a cap attached to the distal end of the scope lumen configured to isolate the scope lumen from the external environment, and a cannula lumen configured to receive a cannula at a second proximal end of the handle and hold the cannula in a desired position. The medical injection assembly includes a cannula configured such that the distance between the distal tip of the cannula and the axis defined by the sheath of the introducer increases as the cannula is moved in a distal direction and a syringe.

Anti-microbial medical injection assemblies for onabotulinumtoxina delivery and methods of use thereof

A medical injection assembly is provided and includes an introducer with a handle, a sheath, and a scope lumen extending from a first proximal end of the handle to a distal end of the sheath, wherein the scope lumen is configured to receive an endoscope at the first proximal end of the handle and hold the endoscope in a desired position. The introducer includes a cannula lumen extending from a second proximal end of the handle to the distal end of the sheath, wherein the cannula lumen is configured to receive a cannula at the second proximal end of the handle and hold the cannula in a desired position. The medical injection assembly includes a cannula configured such that the distance between the distal tip of the cannula and the axis defined by the sheath of the introducer increases as the cannula is moved in a distal direction.
