  • Patent number: 10327759
    Abstract: A multiple-firing crimp device comprises crimps, a shaft, a crimp movement assembly, and a snare. Each crimp has an internal hollow. The shaft has a distal crimping location, an exterior surface, and an interior with the clips stacked therein, the crimps moving therein along a longitudinal axis. The shaft defines a lateral opening proximal to the crimping location and communicates the interior to the environment outside the exterior surface. The crimp movement assembly within the shaft delivers the first crimp to the distal crimping location by moving the first crimp longitudinally from a first proximal position into the distal crimping location and returning to a second proximal position without the first crimp. The snare pulls at least one cord from distal of the first crimp through the first crimp and through a portion of the shaft and out the side of the shaft through the lateral opening.

The oral device has an internal plenum, and a vacuum is drawn in the plenum by a vacuum pump connected by a first tube of the tubular assembly. The vacuum is maintained by an air source which is connected to the plenum by the second tube of the tubular assembly. By maintaining a constant circulating air bleed through the oral device and the connecting tubes, saliva may be removed from the system and collected in a saliva trap located before the vacuum pump.

    Abstract: A pleural drainage system having an inflatable membrane and a method of using the system are disclosed. The pleural drainage system includes a pleural drainage catheter system. The pleural drainage catheter system includes an inflatable membrane and a drainage catheter integrally coupled to the inflation membrane, the drainage catheter defining a drainage lumen through which fluid is drawn from the pleural cavity, and an inflation lumen coupled for flow of inflation fluid to and from an interior of the inflatable membrane. The pleural drainage system further includes a suction system coupled to the drainage catheter and a fluid collector coupled to receive fluid from the drainage catheter. The pleural drainage system further includes an inflation system connected to deliver inflation fluid to the interior of the inflatable membrane. The pleural drainage system may be used to monitor an associated airleak in the pleural cavity of a patient.

  • Patent number: 8956340
    Abstract: A urethral catheter assembly utilizing a removable guide wire for navigating the catheter through a patient's urethral lumen during the insertion procedure. The guide wire being very flexible and having a low coefficient of friction, thus reducing the likelihood of injuring or puncturing the urethra during insertion. The guide wire extends beyond the distal end of the catheter assembly to ensure that the flexible tip of the guide wire is the first contact point between the catheter assembly and the urethral lumen. In one embodiment, the guide wire extends beyond the proximal end of the catheter assembly and is adapted to be handled by a medical doctor to manually maneuver the guide wire through the urethra.

  • Patent number: 8951221
    Abstract: The invention relates to a method and device for the treatment of glaucoma, though insertion of an implant into the lumen of the Schlemm's canal to realize proper drainage of the aqueous humor, which implant is brought into its position in the Schlemm's canal by means of a catheter having a distal and a proximate portion and provided with a number of pores through which a gaseous or fluid medium which comes from a pressure source can emerge during insertion of the catheter carrying the implant into the Schlemm's canal, and while the catheter is being inserted into the Schlemm's canal the gaseous or fluid medium is released under pressure thereby expanding the Schlemm's canal and the implant and upon releasing the implant at its determined location, the catheter can be withdrawn from the Schlemm's canal.

  • Patent number: 8945041
    Abstract: Fluid removal systems and methods for removing a fluid from a tissue site are presented. The systems includes a semi-permeable inbound conduit, which is fluidly coupled to a treatment-fluid delivery unit, for placement proximate to the tissue site, and a semi-permeable outbound conduit, which is fluidly coupled to the inbound conduit and to a treatment-fluid collector, for placement proximate to the tissue site of a patient. The treatment-fluid collector receives a treatment fluid and the fluid, which is recruited, from the tissue site. A recruited-fluid determination unit may be coupled to the treatment-fluid collector to determine a volume of the recruited fluid recruited from the patient. The treatment fluid is any fluid (including a gas) that pulls the recruited fluid from an interstitial and intracellular space. A reduced-pressure treatment subsystem may also be included, among other things, for removing ascites and other fluids from a body cavity.
