Abstract:
A device for collecting a tissue sample includes a needle body extending along a longitudinal axis from a proximal end to a distal end and including a channel extending longitudinally therethrough and a plurality of cut outs extending laterally into the needle body, each of the plurality of cut outs extending at an angle relative to the longitudinal axis from an outer surface of the needle body toward the distal end thereof so that the channel is open to an exterior of the needle body via the plurality of cut outs.
Abstract:
A medical device that comprises a rim defining a loop in a plane and defining a width measured perpendicular to the plane, at least one wire coupled to a distal end of the rim and extending proximally from the distal end out of the plane to a proximal end of the rim, the at least one wire having a cross-sectional dimension measured perpendicular to a longitudinal axis of the at least one wire, the cross-sectional dimension being smaller than the width of the rim, and a sheath configured to cover at least a portion of the rim and a portion of the at least one ware.
Abstract:
A combined system for diagnostic and therapeutic procedures includes a needle extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough, the distal end including a sharp grind for cutting a tissue sample to be collected in the lumen of the needle and a protective sheath sized and shaped to be inserted through the lumen of the needle such that a distal end of the protective sheath extends distally past the distal end of the needle, the protective sheath extending longitudinally from a proximal end to the distal end and including a lumen extending therethrough.

Abstract:
According to one aspect, a medical device may include a shaft including a distal tip with a distal-facing surface. The shaft also may include a fluid lumen extending to the distal tip and a nozzle at a distal end of the fluid lumen. The nozzle may be configured to emit a fluid jet from the distal tip. The shaft also may include a vacuum lumen extending to the distal tip and a vacuum chamber at the distal tip. The vacuum lumen may open into the vacuum chamber, and the vacuum chamber may be wider than the vacuum lumen. The shaft may further include a vacuum opening, and the vacuum chamber may open into the vacuum opening. The vacuum opening may be defined by the distal-facing surface of the distal tip.
