A respiratory protection composite facepiece is disclosed and includes a polymeric rigid facepiece body portion having a first surface and a second surface and a silicone sealing facepiece element chemically bonded at least one of the first surface or the second surface. The first and second surfaces can be opposing major surfaces. A second silicone element is chemically bonded to at least one of the first surface or the second surface. Methods of making the same are also disclosed.

A system and method for forming a seal member onto a substrate from a material is disclosed. The system includes a mold comprising an ultraviolet transmissible material, the mold having a first portion and a second portion operatively coupled to the first portion, the first portion having a first cavity, a second cavity, and a channel extending from an outer surface of the mold to the second cavity. The first cavity has a first shape that is complementary to a first side of the substrate and the second cavity has a second shape that is complementary to the seal member. The system also includes an applicator in fluid communication with the channel, where the applicator is configured to provide the material to the second cavity through the channel, and an ultraviolet irradiation device configured to irradiate the mold with ultraviolet light to cure the material when the material is provided to the second cavity, such that the seal member is formed on the substrate.

Biopsy caps and seals, and methods for making and using the same may be provided in conjunction with an endoscope assembly. A seal may include a main body including a circumferential outer wall surrounding a central lumen. The seal may include at least one support wall extending radially from the outer wall towards a center of the lumen, and at least one helical flap extending from the support wall helically downward along an inner surface of the outer wall, where the at least one helical flap defines an opening at the center of the lumen. The seal may alternatively include a plurality of projections extending radially inward from the outer wall towards a center of the lumen, where the plurality of projections are arranged in a series of circumferentially and angularly offset layers.

The present disclosure relates generally to the field of medical instruments. In particular, the present disclosure relates to a biopsy cap and endoscope biopsy cap housing with improved stability and stress distribution to securely and removably attach to an endoscope biopsy port. In one example, a biopsy cap housing may include a first center-split half comprising a first half of an upper and lower chamber and first pivot member, and a second center-split half comprising a second half of an upper and lower chamber, and second pivot member, wherein mating surfaces of the first and second center-split halves may be configured to interlock to define the upper and lower chambers.

Disclosed is a novel 3D-printer system for printing elastically deformable rubber parts such as rubber seals where the uncured rubber source material is partially cured before printing each rubber layer of the rubber part. Furthermore, disclosed is a novel 3D printing method for 3D-printing an elastically deformable rubber body using the 3D-printer system.

A trim piece for sealing a work surface including a body having a first side, a second side, and a span disposed between the first side and the second side, wherein the first side and the second side are joined at a junction defining an angle between the first side and the second side of between 80 degrees and 100 degrees, a topcap is affixed to the span of the body, wherein the topcap includes a left side having a first wing and a right side having a second wing, an adhesive is bonded to the first side of the body and an aperture is disposed within the body.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

A method of making a flexible seal includes obtaining rigid shims, wherein each rigid shim is a resin impregnated fabric having a three-dimensional structure comprising fibers disposed in three-dimensions. The rigid shims are stacked with intermediate elastomer layers to form alternate layers of intermediate elastomer layer and rigid shim. The stack of rigid shims and intermediate elastomer layer in a seal mold. The intermediate elastomer layers are cured to obtain the flexible seal having alternate layers of rigid shims and elastomer layers. Flexible seals prepared according to the method are also contemplated.

Biopsy caps and seals, and methods for making and using the same may be provided in conjunction with an endoscope assembly. A seal may include a main body including a circumferential outer wall surrounding a central lumen. The seal may include at least one support wall extending radially from the outer wall towards a center of the lumen, and at least one helical flap extending from the support wall helically downward along an inner surface of the outer wall, where the at least one helical flap defines an opening at the center of the lumen. The seal may alternatively include a plurality of projections extending radially inward from the outer wall towards a center of the lumen, where the plurality of projections are arranged in a series of circumferentially and angularly offset layers.

A seal for a vacuum lifter and method of manufacture wherein the seal has a continuous unbroken outer fluid resistant skin of elastomer which forms a boundary around a homogeneous cellular structure with no interior seams or joints.
