A paint brush and method of making the same is disclosed. The paint brush includes a velutinous painting portion having a body including a cavity and an opening, an insert disposed within the body, a handle coaxial with the body, and a ferrule connecting the body to the handle to seal the insert within the body. The body includes an interior face having a rigid surface and an exterior face having velutinous members. The velutinous members include animal fur, synthetic filaments, and/or natural fibers. The method includes sewing fabric having a velutinous surface into a pocket having a cavity, positioning the pocket so the velutinous surface faces an exterior of the pocket, inserting a semi-rigid foam insert into the cavity to form a velutinous painting portion, and connecting the velutinous painting portion to a paint brush handle with a ferrule to form a paint brush having a velutinous painting portion.

An integrated endoscope and accessory treatment device is provided. The device employs a medical treatment device at its distal end that is combined with the endoscope as a complete system. The treatment device is controlled by integrated elements at the proximal end of the endoscope. The treatment devices may include tissue apposition devices, tissue cutting devices, forceps and others.

Integrated endoscope and accessory treatment device

An endoscope tool coupling that facilitates the placement and positioning of a surgical tool within an endoscope. The tool coupling may be configured to accommodate differences in lengths between the surgical tool and the endoscope, which may allow a user to precisely position and maintain the distal end of a surgical tool in a desired location relative to the distal end of the endoscope despite differences and variations in lengths. The tool coupling may have an adjustable configuration to accommodate variations in tool and/or endoscope lengths. The tool coupling employ an arrangement that allows a user to easily increase or decrease the length of the coupling, such as by using a telescoping arrangement. A locking arrangement or mechanism may be provided to secure the coupling in a selected configuration for maintaining the surgical tool in a desired location relative to the endoscope. The tool coupling may be configured to generate a preload on the surgical tool when the tool is positioned in a desired location relative to the endoscope. The tool coupling may be configured to allow for the withdrawal and reintroduction of the same or a similar surgical tool without changing or impacting the original length adjustment and/or preload for the particular tool/endoscope arrangement. The tool coupling may be configured as a separate device that can be attached to various endoscopes, or the tool coupling may be an integrated component of the endoscope.

A multi-lumen biliary catheter in which at least one of the lumens () has a side opening port () configured to guide a guidewire () out of that port at an angle to the longitudinal axis of the catheter. Radiopaque marker bands () having different lengths are placed on the distal end of the catheter adjacent the distal openings to facilitate fluoroscopic identification of the distal end orientation in the biliary tract.

A endoscopic multiple sample biopsy forceps is disclosed having a jaw assembly with a pair of jaws connected to a pair of arms extending from a jaw housing. Each jaw has two shanks oppositely displaced from the longitudinal axis of the device to define a space in the rear of the jaw for storing collected tissue samples. The tissue storage space defined by the jaw shanks opens rearwardly into a tissue storage area defined within the housing. Each shank has a broad outwardly facing planar surface aligned with an inwardly facing planar surface on one of the pair of arms. A cam slot on each jaw shank is slidably engaged by a cam pin on one of the pair of arms. A puller member coaxially positioned in the housing and axially movable relative to the housing supports a pair of pivots, each of which pivotally engages a bore on at least one jaw shank. The puller member is attached to a drive wire coaxially positioned in a tubular shaft. Axial movement of the drive wire actuates the puller member. In response to axial movement of the puller along the longitudinal axis of the outer tube, the cam pins riding in the cam guide slots change the position relative to the fixed jaw pivot axis of the jaw, thus actuating the jaws. None of the jaw assembly elements movable relative to the device, except the jaws, are externally exposed such that they could contact targeted tissue and negatively affect tissue sampling operations. An ejector is provided to push collected samples from the tissue sample storage area.

A papillotome has an elongated sheath and plural longitudinal lumens, a proximal end and a distal end wherein the sheath is sized to be received within an endoscopic lumen. The distal end has a pre-curved shape memory tip for controlling the bending and orientation of the distal end. The pre-curved shape memory tip has a set configuration wherein the tip retains the set curve configuration when the distal end is in a relaxed configuration. A cutting wire having a longitudinal cutting edge is located along the distal end of the sheath which is movable in a cutting plane. The cutting wire is connected to a conductor disposed within one lumen of the sheath. A guidewire is disposed within another lumen of the sheath for guiding the pre-curved shape memory tip within the endoscopic lumen. A third lumen may be provided for delivering or injecting a fluid such as contrast. The package for the papillotome includes curve retention device which retains the pre-curved shape memory tip in the set curve configuration during transit and storage.
