Devices and methods for a cannula-delivered treatment material application device
First Claim
1. An ophthalmic surgical instrument comprising:
- an elongate tubular member having a proximal end, a distal end, and a lumen extending therebetween, the elongate tubular member being configured to penetrate a body cavity of a patient;
a wicking member extending beyond the distal end of the elongate tubular member, the wicking member configured to secure a volume of treatment fluid delivered through the lumen to the wicking member for application from the wicking member to a target tissue in the body cavity;
a fluid source system, comprising;
a reservoir comprising the treatment fluid; and
a dispensing system, coupled to the elongate tubular member, configured to cause the treatment fluid from the reservoir to be dispensed through the lumen of the elongate tubular member;
wherein the wicking member comprises a loop of a material extending out from the lumen of the elongate tubular member;
wherein the loop comprises a closed distal end and wherein a proximal end of the loop extends into the elongate tubular member to receive the treatment fluid.

Abstract
Methods and systems for performing an ophthalmic surgical treatment procedure include one or more wicking members to secure a volume of treatment fluid to a distal end of a surgical instrument. Such a surgical instrument may include an elongate tubular member having a proximal end, a distal end, and a lumen extending therebetween, the elongate tubular member being configured to penetrate a body cavity of a patient. The instrument may further include a wicking member extending beyond the distal end of the elongate tubular member. The wicking member may be configured to secure a volume of treatment fluid delivered through the lumen to the wicking member for application from the wicking member to target tissue in the body cavity.
