  • Patent number: 11957351
    Abstract: Tissue ligation systems and methods are provides to mechanically strangulate abnormal or undesirable tissue. Tissue ligation systems include a multi-lumen catheter having an outer diameter smaller than the inner diameter of a standard endoscope channel such that the catheter can be inserted into the endoscope. Tissue ligation systems also include a ligation apparatus with an expandable hood disposed at the distal end of the catheter. A suture extends through a lumen of the catheter and has a distal loop portion that can strangulate tissue.

  • Patent number: 9968765
    Abstract: A convection enhanced delivery device comprises a support member and an elongated microcatheter carried by the support member. The microcatheter projects lengthwise away from the support member. The microcatheter includes a catheter lumen extending in a first direction. A fluid conduit carried by the support member. The fluid conduit includes a conduit lumen that extends in a second direction different than the first direction. The conduit lumen is in fluid communication with the catheter lumen. An inlet port and a connecting port are also carried by the support member. The inlet port is in fluid communication with the fluid conduit. The connecting port is separate from the inlet port and is in fluid communication with the fluid conduit. The connecting port is configured to engage an end portion of an external fluid conduit such that the external fluid conduit projects away from the connecting port and from the support member.
