Abstract: An endoscopic snare device (10, 100, 100?) includes a pair of bowed, resiliently deformable, snare wires (12, 14) with bow shaped memory, a mesh (20) attached to mid-portions (16, 18) and distal portions (22, 24) of the snare wires (12, 14) for a mesh length (A) that is less than the snare length (L), a bowed, resiliently deformable, support wire (116) extending in a plane out of the plane of the snare wires (12, 14), and a pair of bowed, resiliently deformable, incising wires (112, 114) side by side with the snare wires (12, 14). The support wire (116) is electrically insulated. A mouth cord or wire (46) extends from one snare wire (12), through the support wire (116), and to the other snare wire (14).

Abstract: Surgical retrieval devices for capturing tissues and fluids in endoscopic and laproscopic operations include a semi-rigid, resiliently collapsible and expandable basket comprising a structural combination of resilient, semi-rigid snare wire and frame wire members that are formed with a yieldable bend configuration that together flare into a basket form when extended out of a catheter. The basket is enhanced by surrounds of net, mesh, or impervious material for retaining smaller bits of tissue or fluids, or with a web of interspersed flexible threads for enhanced tissue retaining capability.

Abstract: A device for retrieval of organic and inorganic matter during a surgical procedure employing a camera and viewer to ascertain a removal target. The device has a catch basket formed of a plurality of radially oriented shaped wires extending an axis with gaps in-between for camera viewing and light transmission. A mouth aperture area is maximized by formation in a single plane and using wires of a shape to form an oval, crescent, or hexagon. A cauterizing snare may be formed using wires forming the mouth, may project from the catch basket, or may be used separate from the catch basket. Shaped memory material forming the wires maintains the shape of the catch basket, mouth, and snare, despite repeated compressions thereof into catheter housed conduits.

Abstract: A tissue and/or cell sampling device for biopsies having a catheter sized for translation through a lumen on an instrument such as a bronchoscope. An aspiration needle engaged to a control member is employable by translation to remove a core of tissue from a sampling location. The translation can be limited to maintain the needle retracted into an axial passage. Forceps or a brush are translatably engaged within the axial core of the needle and are translatable from the tip of the needle to take tissue and/or cell samples. The device is employable to allow for use of either sampling device independently, or sequently, to allow deep tissue and/or cell samples to be retrieved from the distal end of the core tissue sample retrieved by the needle.

Abstract: An engagement system for a surgical sensor assembly, formed of a sensing component in a fixed position and a lead wire in an electrical communication therewith. The engagement system employs a jacket of heat shrink polymeric material to hold the sensing component to the lead wire and eliminates the employment of soldering and welding and crimping which can damage such sensing components. The system is employed in combination with catheters having a lumen for control wires for surgical instruments.

Abstract: A surgical instrument featuring a combination cauterizing and surgical capture component. The instrument is deployable from a distal end of a lumen to a first position partially exposing a cauterizing loop and having restrained radially deployable members wherein a plurality of cauterizations may be performed with said cauterizing loop in an unobstructed view of a camera or lens. The instrument is deployable to a second position fully translated from the lumen whereafter the plurality of radially positionable members may be released by activation of a release member allowing the biased members to deploy radially around an axis running through the loop.

Abstract: A surgical capture component for deployment from a distal end of a catheter formed of a plurality of radially positionable shaped members each having a deployed position biased to radially position around a center axis and having a collapsed position adjacent to a loop a planar loop portion. The loop may be electrified to cauterize tissue. Deployment of the shaped members is provided by mechanical release or automatic release of a restraint when the loop is electrified.
