  • CATHETER DISTAL TIP CONFIGURATION
    Publication number: 20160346508
    Abstract: In some examples, an outer jacket of a catheter body comprises a first section that decreases in durometer along a length of the first section in a direction towards a distal end of the catheter body, and a second section more distal than the first section and including the distal end of the catheter body, the second section having a higher durometer than a distal portion of the first section. The second section of the outer jacket and the inner liner define a distal opening of the catheter body that is configured to resist geometric deformation when the distal end of the catheter body is engaged with a guidewire.

  • OVERMOLDED TUBING ASSEMBLY AND ADAPTER FOR A POSITIVE DISPLACEMENT PUMP
    Publication number: 20150354555
    Abstract: A tubing assembly is provided that can comprise a plurality of tubes or lumens that can be disposed within a head of a peristaltic pump. The tubing assembly can provide a flow rate or volume capacity that is generally equal to or greater than that achieved with a comparable prior art tube while operating at higher pressures than that possible using the prior art tube. Further, in accordance with some embodiments, the tubing assembly can achieve a longer working life than a comparable prior art tube, and the load on the pump motor can be reduced such that the pump life is increased and/or a larger pump motor is not required to achieve such advantageous results.
