Biopsy device

A biopsy device for percutaneous tissue removal includes an elongated housing having an operational axis, a stylet hub slidably mounted in the housing, where the stylet hub is movable relative to the housing between a proximal, armed position, and a distal, fired position, the stylet hub having a stylet strike, a cannula hub slidably mounted in the housing alongside the stylet hub, and a spring-biased arming member. The cannula hub is movable relative to the housing between a proximal, armed position, and a distal, fired position. The arming member is moveably mounted to the housing proximal of the respective stylet and cannula hubs, and configured for manually-actuated movement from a relaxed, extended position to a loaded, compressed position to define a compressive arming stroke. The biopsy device also includes an arming member biasing spring that restores the arming member from the compressed position to the extended position.

Biopsy device arming mechanism

A catheter is provided including a first lumen and a second lumen. A first member is disposed for relative movement within the first lumen and defines a cavity, A second member is disposed for relative movement within the second lumen. The cavity of the first member is configured for disposal of the second member. The catheter may include an elongated tubular body that includes the first lumen and the second lumen. The first member may have a distal portion that extends beyond the distal end of the body. The distal portion may include the cavity. The cavity may be defined by a member lumen. The first and second members may include tubular stylettes. The second member may include a guidewire.

Catheter insertion apparatus

A catheter is provided including a first lumen and a second lumen. A first member is disposed for relative movement within the first lumen and defines a cavity. A second member is disposed for relative movement within the second lumen. The cavity of the first member is configured for disposal of the second member. The catheter may include an elongated tubular body that includes the first lumen and the second lumen. The first member may have a distal portion that extends beyond the distal end of the body. The distal portion may include the cavity. The cavity may be defined by a member lumen. The first and second members may include tubular stylettes. The second member may include a guidewire.

A catheter assembly includes a catheter, a hub, and a sealing member. The catheter defines one or more lumens. The hub includes one or more hub extensions dimensioned to be received within the one or more lumens of the catheter. The sealing member is positioned adjacent the interface of the catheter and the hub. The sealing member includes an expandable material which increases in volume upon exposure to moisture.

Catheter assembly including sealing member

A medical catheter assembly includes a catheter hub, an elongate catheter member extending from the catheter hub and having at least one longitudinal lumen for passage of fluids, an extension tube extending from the catheter hub and defining an internal lumen in fluid communication with the at least one longitudinal lumen of the catheter member and a clamp positionable about the extension tube. The catheter hub defines a reduced profile to facilitate passage of the catheter hub through a surgical tunnel. The clamp includes first and second clamp sections and defines a longitudinal clamp axis. The clamp has a longitudinal opening for passage of the extension tube and a movable member adapted to move from a first position to a second position to substantially close the internal lumen. The first and second clamp sections are separable to facilitate transverse positioning of the clamp sections about the extension tube.

Low profile catheter assembly

A hemodialysis catheter assembly adapted for use in a subcutaneous tunneling procedure incorporates a mechanism for securing the catheter hub member to the elongated catheter, and to provide the requisite fluid communication between fluid passages within the hub and the catheter lumens within the catheter. The catheter hub member may be connected to the elongated catheter after implantation of the catheter via a subcutaneous tunneling procedure.

Catheter system with attachable catheter hub

An instrument for facilitating insertion of a catheter through a subcutaneous tunnel includes a tunneling stylet defining a longitudinal axis and having leading and trailing ends, a bifurcated segment adjacent the leading end of the tunneling stylet and a releasable cover releasably mountable to the leading end of the tunneling stylet to substantially enclose the bifurcated segment. The bifurcated segment includes first and second elements adapted for reception within respective lumens of a catheter.
