  • Publication number: 20260199583
    Abstract: A size-classifier (12) for dividing adipocyte cells into specific size fractions is provided inclusive of a carousel (14) rotatably mounted in a classifier vessel (12v) to rotate about a classifier axis (Z12). The carousel (24) is divided into compartments (14.1-14.n) separated by compartment walls, each having a transverse wall portion which is transverse to a radial direction of the carousel wall (14w). The transverse wall portion separating an ith compartment (14.i) from a (i+1)th compartment (14.(i+1)), with i=1 to (n?1), includes a mesh of ith opening (Ri), smaller than an (i?1)th opening (R(i?1)) of a transverse wall portion separating a (i?1)th compartment (14.(i?1)) from the ith compartment (14.i), (i.e., R(n?1)<R(n?2) . . . <Ri< . . . <R1). A liposuction kit-of-parts and assembly for liposuction and treatment of the liposuction aspirate as to size classification is also provided.

  • Patent number: 12357743
    Abstract: A powered handpiece for imparting to a cannula of a medical device a reciprocal movement of amplitude (?x) along a longitudinal axis (X) is provided. A housing (1) at least partially encloses a hollow tube (2) extending along the longitudinal axis (X) between an inlet end (2i) and an outlet end (2o), the inlet end (2i) being configured for coaxially coupling the hollow tube (2) to a hollow cannula (10). A ring (3) rigidly is coupled to the hollow tube (2) and has an opening (3o) defined on a plane (X, Y), having a length, L, Y?X. A cam (4) mounted on a rotation axle (4r) parallel to a second transverse axis (Z) normal to the plane (X, Y) (i.e., X?Y?Z), offset from a centroid (C) of the cam on the plane (X, Y) by a distance (?P), and set at a fixed position relative to the housing (1), the cam being engaged in the opening (3o).

  • Publication number: 20170136327
    Abstract: A play structure for the practice of basketball, comprising a base that rests on the ground, as well as: a lower element mounted in rotation on said base between a folded down position and an upright position; an upper element on which is mounted a basketball backboard (4), said upper element being mounted in rotation on an upper end of said lower element between a folded position and a deployed position; said play structure being arranged from a storage position to a position of use by successively switching the lower element from the folded down position to the upright position, then the upper element from the folded position to the deployed position, the lower element being arranged to rest on the ground in upright position.

  • Patent number: 9457177
    Abstract: Example kits of parts, apparatus and methods for liposuction and lipofilling of adipose tissue are disclosed. An example kit includes an extraction unit comprising a liposuction device having a cannula coupled to a handpiece, which imparts movement to an inlet end of the cannula. The example kit includes a separation unit, a re-injection unit, a vacuum pump, a re-injection pump, and tubing for connecting the elements of the kit of parts to form an apparatus for liposuction and lipofilling of adipose tissue. The example handpiece imparts to the inlet end of the cannula a vibrational movement comprising a first, linear component and a second, orbital component. The example kit also includes a three-way valve having an aspiration position to bring a retentate volume of the separation unit in communication with the re-injection pump, and an injection position to bring the re-injection pump in communication with the lipofilling device.

  • Publication number: 20160151691
    Abstract: The invention relates to a portable device (10) for a game of skill consisting in causing an article to pass through a target, the device comprising: a board (12) having a front face (18) and a rear face (20); a target (14) including a through opening (28) defining an axis (A) and through which the article can pass, said target being fastened by a hinge (38) to the board in such a manner that the portable device can occupy either a folded position in which the target is folded against the front face (18) of the board, or a deployed position in which the target extends transversely relative to the board; and fastener means (16) configured to enable the portable device to be fastened to a support. The invention is characterized by the fact that at least one of the elements selected from the board (12) and the target (14) is constituted by assembling together a layer of hard plastics material and a layer of foam.
