Definitions

  • the present invention relates generally to medical devices for tissue surgery (e.g., soft tissue surgery), for example devices that perform functions including but not limited to infusion, aspiration, processing, reinjection, and/or transportation of soft tissue.
  • soft tissue include but are not limited to body fluids such as adipose tissue, blood, serum, bone marrow, and/or infected tissue and/or unwanted tissue.
  • Tissue surgery may involve a variety of separate processes including infusion of sterile saline and/or medications to a surgical site, aspiration of soft tissue and a portion of the sterile saline and/or medication, processing of the soft tissue for reinjection, reinjection of the soft tissue, and transportation (e.g., transportation of various materials including saline, medication, tissue), infusion may employ the use of syringes for low volume infusion (e.g., 300 cc or less) or a special infusion pump (e.g., peristaltic or pressure) for high volume infusion (e.g., greater than 300 cc).
  • Equipment for the infusion processes are generally unique, for example they are generally only used for the infusion step of the soft tissue surgery.
  • Low volume aspiration procedures may employ a syringe (different from the syringe from the infusion step), for example a syringe with an attached needle or cannula.
  • a syringe different from the syringe from the infusion step
  • an incision is made in the skin and the needle/cannula is inserted through the incision site so that the distal end of the needle/cannula lies within the cells to be extracted.
  • the plunger of the syringe is extracted, creating negative pressure within the syringe, there by drawing the cells into the syringe. If this technique is used for larger volumes, a repeat of the steps is required, which exposes the cells to air. Further, there is a heightened risk of infection with the repeated insertion of the needle/cannula. This technique is also detrimental to cell viability. This technique is impractical for high volume aspiration as it is labor intensive and time consuming.
  • Large volume aspiration procedures may employ a special aspirator that uses air and negative pressure (e.g., a powered vacuum pump attached to a tube) to remove the cells from the surgical site and deposit the cells into a collection chamber.
  • This aspiration technique presents problems, for example the negative pressure may damage the tissue, the equipment may weigh between about 40 to 120 pounds, the equipment may be expensive, the harvested tissue may become exposed to air, which can compromise the viability of the tissue cells, and the high velocity of the tissue aspiration may compromise cell viability.
  • the aspirator equipment is generally unique to the aspiration step.
  • the tissue is processed.
  • the tissue may be cleaned, separated (e.g., via a centrifuge, decanter, multiple syringes), and then transferred to multiple syringes for reinjection.
  • the processing equipment and supplies are generally unique to the processing step. Often the soft tissue must be transferred first from the aspiration equipment and then be transferred to the reinjection equipment.
  • the soft tissue is often transferred to a series of small syringes.
  • the physician injects (e.g.. by hand) the soft tissue to a desired surgical site.

Abstract

L'invention concerne un dispositif multifonctionnel muni d'une cartouche présentant un premier et un second orifices, une première et une seconde chambres qui ont des orifices de sortie disposés au niveau d'extrémités proximales reliées à des tubes qui se ramifient pour former des tubes d'admission et des tubes de déposition, des valves unidirectionnelles étant disposées dans les tubes d'admission et de dépôt, des pistons étant disposés dans les chambres qui oscillent entre un déplacement vers l'extrémité proximale ou vers l'extrémité distale. Selon l'invention, lorsque le piston se déplace vers l'extrémité distale, une matière peut être aspirée dans la chambre et lorsque le piston se déplace vers l'extrémité proximale, la matière peut être pompée hors de la chambre. Les tubes d'admission utilisés sont formés à partir de la ramification d'un tube d'admission principal relié fluidiquement au premier orifice et les tubes de déposition alimentent un tube de déposition principal relié fluidiquement au deuxième orifice, le dispositif de l'invention pouvant pomper la matière du premier orifice au deuxième orifice.
