A61B 17/56
B67D 7/74

US Classification:

606 93, 3661831, 2221455, 222391

Abstract:

An apparatus and method for transferring curable material to an injector to convenient deliver the curable material to a patient. The apparatus contains a mixing chamber for mixing a liquid component and a powder component to form a curable material. The curable material is transferred to an injector to when the mixing chamber and injector are moved toward each other.

John Ray - Indian Creek IL, US

International Classification:

A61B 17/88
A61F 2/28

US Classification:

606 94, 623 2362

Abstract:

A curable material delivery cannula device and method are disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment forming a plurality of pre-set curves, each of which corresponds to a pre-determined temperature of the cannula, a lumen, and side orifice(s) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When distally extended from the guide cannula, and upon being heated to a predetermined temperature (before, during, or after extension), the deflectable segment assumes a curved shape, which may be used to create a void in the bone for receiving curable material. The distal cannula end includes a blunt tip for non-traumatic interface with bodily material. During use, curable material, such as bone cement, is delivered from the side orifice(s) in a radial direction relative to the lumen.

Abstract:

A system for augmenting a bone structure. A shape memory device includes a deflectable distal segment including temperature-dependent memory metal material. The shape memory device is slidably received within a guide cannula. The deflectable distal segment may include a substantially longitudinally straightened form, such as when subjected to a force from the guide cannula. The deflectable distal segment forms a first deflected shape having a first bend away from said straight longitudinal axis at a first elevated temperature greater than an initial temperature, and forms a second deflected shape having a second bend away from said straight longitudinal axis at a second elevated temperature greater than said first elevated temperature. The shape memory device may create voids within the bone structure with the deflectable distal segment at the first and/or second bends. Methods for positioning a shape memory device within a bone structure are also disclosed.

A61B 19/00

Abstract:

System and components for inducing pleurodesis or other sclerosis or desired adhesion conditions to treat a patient, while minimizing likelihood of tissue damage from direct application of sclerosis-enhancing materials. A tube device is provided that is configured to elute sclerosis-enhancing material and/or other medicaments via a fenestrated drainage tube. The assembly of tube device with outer (typically drainage) tube may include one or more features configured to enhance delivery of medicament and/or drainage through the same assembly.
