CN-122028837-A - Instrument wetting accessory

Abstract

A biopsy cap may be operably connected to a port of a medical device. The biopsy cap seals a working channel configured to allow devices of different diameters to pass through. During endoscopic procedures, the tips of many devices (e.g., guidewires and catheters) may be wetted prior to use to avoid excessive drag forces during insertion of the devices into the working channel of an endoscope. A cap system includes a cap for a port of a first medical device, and a wetting device configured to couple to a portion of the cap and wet a second medical device passing through the cap system.

Description

Instrument wetting accessory Cross Reference to Related Applications In accordance with 35 U.S. c. ≡119, the present application claims priority from U.S. provisional application No. 63/520,392 filed on 8/18 of 2023, the entire contents of which are incorporated herein by reference. Technical Field Aspects of the present disclosure generally relate to medical device components, assemblies, and related methods. In particular, aspects of the present disclosure relate to devices, systems, methods, and the like for wetting instruments at a biopsy port entrance. Background The biopsy cap may be operably connected to a port of a medical device (e.g., a duodenal scope, an endoscope, a bronchoscope, an ultrasound Endoscope (EUS) endoscope, etc.). The biopsy cap can seal a working channel configured to allow devices of different diameters to pass through. The biopsy cap also helps to prevent leakage of biofouling. During endoscopic procedures, the tips of many devices (e.g., guidewires and catheters) may be wetted prior to use to avoid excessive drag forces during insertion of the devices through the working channel of the endoscope. Furthermore, wetting the tip of such devices may also prevent the device from becoming stuck in the mucosa. Disclosure of Invention Each aspect disclosed herein may include one or more features described in connection with any other disclosed aspect. In one example, a cap system may include a cap for a port of a first medical device and a wetting device configured to couple to a portion of the cap and wet a second medical device passing through the cap system. Any of the apparatus disclosed herein may additionally or alternatively include any of the following features in any combination. The wetting device may comprise a base film at the bottom of the wetting device. The carrier film may be pierced to form an opening in the carrier film. The wetting device may comprise a top film at the top of the wetting device. The top film may be pierced to form an opening in the top film. The cap system may further comprise a wetting liquid located between the top and bottom membranes of the wetting device. The flange of the wetting device may define a bottom opening configured to receive the portion of the biopsy cap. The flange may be a bottom portion of the wetting apparatus and may extend below the carrier film, wherein the bottom opening is located radially inward of the flange. The flange may define a first opening to fit around and receive the grip portion of the cap. The flange may define a second opening to fit around and receive a connector that couples the lid of the cap to the base of the cap. The wetting device may comprise a sponge configured to hold a wetting liquid. The sponge may be configured to be placed over and coupled with the portion of the cap. The sponge may define a through-hole centrally located in the sponge and extending from the top of the sponge to the bottom of the sponge. The diameter of the through-hole may be about 0.05 inches. The cap may further comprise a coating on at least one outer side of the sponge. In another example, a wetting device may include a tube having a generally cylindrical shape defining an interior for containing and retaining a liquid and allowing a first medical device to pass through, wherein the tube is configured to be placed on top of a base of a cap of a port of a second medical device, the tube including a bottom locking structure for coupling the tube to the base. Any of the apparatus described herein may additionally or alternatively include any of the following features in any combination. The tube may further comprise a top opening configured to receive a lid of the cap and a top locking geometry for coupling the tube to the lid. In another example, a wetting device may include a sponge defining a through hole extending within the sponge from a top of the sponge to a bottom of the sponge, the through hole opening at the top of the sponge and opening at the bottom of the sponge to allow a first medical device to pass through the through hole, wherein the sponge includes a flange at the bottom of the sponge, the flange defining a bottom opening configured to receive a portion of a cap of a port of a second medical device, and a coating on an outer side of the sponge to inhibit leakage of liquid absorbed by the sponge. Any of the apparatus described herein may additionally or alternatively include any of the following features in any combination. The flange may include a first opening configured to fit around and receive the grip portion of the cap and a second opening configured to fit around and receive a connector that couples the cover of the cap to the base of the cap. The wetting apparatus may have a generally cylindrical shape. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.
