Abstract
The present disclosure relates generally to the field of minimally invasive catheter-based devices and procedures for the removal of necrotic debris. In particular, the present disclosure relates to systems and methods for the removal of necrotic debris from within a walled off necrosis without disrupting or damaging the tissue wall of the necrotic pocket.
Claims17
A system, comprising:
- an elongate member, comprising:
- a distal end, and
- a proximal end;
- and
- a tissue disrupting element on the distal end of the elongate member, the tissue disrupting element including a plurality of cutting members comprising a cutting edge, the plurality of cutting members disposed about a support shaft extending from the elongate member, wherein the plurality of cutting members include a proximal end directly attached to a proximal portion of the support shaft, and wherein a respective one of the plurality of cutting members extend from the elongate member, and the respective one of the plurality of cutting members is configured to move between a delivery configuration in which the respective one of the plurality of cutting members is constrained and a deployed configuration in which the respective one of the plurality of cutting members bows radially outward, and
- wherein the elongate member comprises a plurality of grooves, each of the plurality of grooves configured to slidingly accept a corresponding member of the plurality of cutting members.
3 more elements
A device, comprising:
- an elongate member;
- a support shaft slidably disposed within the elongate member;
- and
- a plurality of cutting members comprising a cutting edge, the plurality of cutting members having a proximal end directly coupled to the support shaft, wherein the plurality of cutting members, and wherein when the plurality of cutting members extend from the elongate member, the plurality of cutting members are configured to move between a delivery configuration in which the plurality of cutting members is constrained and a deployed configuration in which the plurality of cutting members bows radially outward,
- wherein the elongate member comprises a plurality of grooves, each of the plurality of grooves configured to slidingly accept a corresponding member of the plurality of cutting members.
2 more elements
A device, comprising:
- an elongate member comprising a lumen therethrough;
- a support shaft disposed within the lumen of the elongate member;
- and
- a plurality of cutting members disposed about the support shaft, each of the plurality of cutting members having a proximal end directly coupled to the support shaft, wherein the plurality of cutting members extend from the elongate member, the plurality of cutting members are configured to move between a delivery configuration in which the plurality of cutting members are constrained and a deployed configuration in which the plurality of cutting members bow radially outward;
- wherein the elongate member further comprises a plurality of grooves, each of the plurality of grooves configured to slidingly accept each corresponding member of the plurality of cutting members.
