Catheter system for making a surgical cut in the pericardium

Patent published on the 2026-05-21 in WO under Ref WO2026107056 by HEART FAILURE SOLUTIONS INC [US] (Strong Mark Henry [us], Bursey Alexandra Dean [us])

Abstract: This document describes a catheter system for creating an opening in a pericardium. The catheter system includes a sheath defining a sheath lumen that includes a distal opening and a catheter sized to slidably fit within the sheath lumen so that the catheter extends through an entire length of the sheath lumen with a distal portion of the catheter extending beyond the distal opening of the sheath lumen and into a space underneath a pericardium of a patient. Additionally, the catheter system incl[...]


Our summary: The document describes a catheter system designed for creating an opening in the pericardium. It features a sheath with a lumen and a catheter that extends through it, allowing for a blade to cut the pericardium. The blade is retractable and only extends when the catheter withdraws.

Axially-actuated micro-forceps with force-modulated jaws

Patent published on the 2026-05-21 in US under Ref US20260137408 by EYEMACULAR REGENERATION INC [US] (Olsen Timothy W [us], Love John Christian [us])

Abstract: [0000] A medical device includes a sheath having a lumen and wall that extends along a length between ends, with an opening in its side near the tip. A movable shaft fits inside the sheath s lumen. The device has two jaws—one formed from a hanging portion of the sheath wall next to the side opening, and another formed at the shaft s tip. The jaws can move between closed and open positions as the shaft slides within the sheath. A mechanism controls the squeezing force between the jaws. Both jaw[...]


Our summary: The device features a sheath with a movable shaft and two jaws for gripping. The jaws can open and close as the shaft slides within the sheath. A mechanism regulates the force applied by the jaws, allowing operation through small openings.

Preparation of surgical indocyanine green-dyed gauze using an autoclave and its near-infrared fluorescence properties

Published on 2026-04-21 by Hidekazu Yasunaga, Yoshihiko Tashiro, Shinji Ando @NATURE

Abstract: Polymer Journal, Published online: 21 April 2026; doi:10.1038/s41428-026-01170-9A near-infrared fluorescent surgical gauze was developed by dyeing cotton with indocyanine green (ICG) using an autoclave at 121–132 °C and 0.21–0.29 MPa. The optimal condition (1.5 × 10⁻⁴ mol L–1 ICG, 132 °C, 10–15 min) yielded the brightest fluorescence. Post-sterilization (PS) enhanced fluorescence by dissolving ICG aggregates and improving fixation. The gauze’s color remained similar [...]


Our summary: A near-infrared fluorescent surgical gauze was created by dyeing cotton with indocyanine green using an autoclave. The optimal conditions for dyeing produced the brightest fluorescence, which was further enhanced by post-sterilization. This gauze effectively emits strong NIR signals through tissue and minimizes dye leakage, aiding in surgical site identification.
