摘要： Disclosed embodiments include apparatuses and methods for deploying a coilable filament on opposing sides of a surface. An apparatus includes a needle mechanism configured to extend and withdraw the needle. A coil mechanism is configured to advance a stylet through the needle to extend a coilable filament at a distal end of the stylet. An interlock mechanism is configured to control operations of the needle mechanism and the coil mechanism, including moving the needle and the stylet in concert to extend the needle and coilable filament to a distal side of the surface, separately advancing the stylet to extend a first segment of the coil on the distal side of the surface, withdrawing the needle to the proximal side of the surface, and separately further advancing the stylet to deploy a second segment of the coil along the proximal side of the surface.

摘要： Disclosed embodiments include catheter assemblies, systems for sampling a targeted region of tissue, and methods of sampling a targeted region of tissue. In an illustrative, non-limiting embodiment, a catheter assembly includes: a catheter defining a lumen therein, a wall of the catheter defining an opening therein at a distal end of the catheter; a flexible needle disposable in the lumen; and an offset mechanism configured to urge the needle to extend from the opening at the distal end of the catheter at an angle that diverges from an axis of the lumen.

摘要： A needle apparatus having a sheath with a protective hypotube insert and a method of making the needle sheath. An example needle apparatus includes a handle, a needle having a proximal end connected to the handle and a sheath. The sheath is configured to receive of the needle. The sheath includes a proximal end connected to the handle, a distal end, a lumen and the protective insert. The lumen passes from the proximal end to the distal end of the sheath. The protective insert is received within the lumen at the distal end of the sheath when force and/or heat are applied.

摘要： An apparatus, comprising: a biopsy needle having a distal end and a proximal end, all or a portion of the biopsy needle being movable between a collapsed state and an expanded state; a sheath having a distal end and a proximal end, wherein the biopsy needle in the collapsed state is contained within the sheath, and in the expanded state at least the distal end of the biopsy needle extends from the distal end of the sheath; wherein the biopsy needle is provided with two or more sleeves, which at least partially overlap in the collapsed configuration and which cylindrically expand to provide an increased radius, relative to a radius in the collapsed state, for sampling in the expanded configuration, and wherein a cross section of the distal end of the biopsy needle in the expanded state is a substantially circular cross section.

摘要： A device for tissue sampling that comprises a needle, a stylet and a sealing member. The needle comprises a distal tip, a proximal end, and one or more interior portions. The needle extends along a longitudinal axis extending between the distal tip and the proximal end. The stylet is moveably supported within the one or more interior portions of the needle. The sealing member Is moveably supported within the one or more interior portions of the needle and substantially conforms to the one or more interior portions, The distal tip is configured to obtain a tissue sample. The stylet and the sealing member are movable, along the longitudinal axis away from the distal tip so that a local vacuum is created at the distal tip so that obtained tissue samples can be aspirated into the needle.

摘要： Disclosed embodiments include apparatuses, systems, and methods for driving a needle to facilitate suturing, such as may be performed in a surgical anastomosis procedure. In an illustrative embodiment, an apparatus includes a frame. First and second rollers are rotatably mounted parallel with each other in the frame and are configured to engage therebetween a shaft of a needle formed in a helical shape. The first and second rollers are configured to counter-rotate. The needle is revolvable eccentrically around the first roller responsive to counter-rotation of the first and second rollers. A drive mechanism is secured to the frame and is configured to move the frame.

摘要： A medical instrument having an aspiration needle and a protective needle cap. The cap protects a scope from damage due to needle insertion. The cap is placed over the end of a needle before insertion into an endoscope (e.g., bronchoscope) before use in a patient. The cap includes a first section having a first cross-sectional dimension based on an outside diameter value of a distal end of a medical device used in an endoscope and a second section having a second cross-sectional value that is smaller than the first cross-sectional value. A connection force exists between the first section and the distal end of the medical device, the connection force being greater than a frictional force between the device and an interior wall of an endoscope as the medical device is moved within the endoscope.
