A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.

Palm activated drug delivery device

Single vial holder

An infusion device comprising an infuser base, a cannula and a ferrule. The infuser base having a bore extending therethrough, the bore having distal and proximal ends and defining a shoulder therebetween. The cannula having distal and proximal ends, the proximal end having an inside first diameter. A flange extends radially outward from the cannula proximal end. The cannula is positioned in the bore such that the flange is positioned adjacent the shoulder. The ferrule has an insertion portion, having an outside second diameter which is substantially equal to the first diameter, and a tapered portion extending from the insertion portion. The ferrule is positioned in the bore such that the insertion portion and a portion of the tapered portion are received in the cannula proximal end and the flange is compressed between the shoulder and the tapered portion to define a seal between the cannula and ferrule.

Method and systems for providing an infusion device interface

A surgical introducer sheath comprising a first member having a first longitudinally extending lumen dimensioned to receive a surgical instrument therethrough, a second member having a second longitudinally extending lumen dimensioned to receive the first member, and a retainer adjacent a distal portion of the second member movable from a first retracted position to a second extended position to limit proximal movement of the introducer sheath. Rotational movement of the second member in a first direction moves the retainer to the extended position and rotational movement of the second member in a second direction moves the retainer to a retracted position.

Introducer sheath with retainer

A dialysis catheter comprising a catheter body having a proximal portion, a distal portion, a first longitudinally extending central lumen configured to deliver blood, and at least three longitudinally extending lumens positioned radially of the central lumen and configured to withdraw blood from a patient. At least one blood delivery opening is formed in the distal portion of the catheter body and in fluid communication with the first lumen and configured for passage of blood therethrough. At least three blood withdrawal openings are formed in the outer wall of the catheter body, wherein each of the openings is in fluid communication with one of the at least three lumens and is configured for passage of blood from a patient.

Dialysis catheter

A distal protection device comprising a catheter, a flexible member movable from a first position to a second looped position extending laterally with respect to the catheter, such that a first loop opening extends substantially in a direction of blood flow as the first loop opening extends in a plane substantially parallel to a transverse axis of the catheter, and filtering material movable from a collapsed position to an expanded position in response to movement of the flexible member.

Distal protection device

A dialysis catheter comprising a first portion having a first dianeter, an elongated distal portion having a second diameter smaller than the first diameter, and a transition region between the first portion and distal portion. A first longitudinally extending central lumen configured to deliver blood terminates in an opening in the distal portion. At least two independent longitudinally extending lumens are positioned radially of the first lumen, configured to withdraw blood from a patient, and terminate in a longitudinally directed opening in the transition portion.

A method of inserting a dialysis catheter into a patient comprising the steps of inserting a guidewire into the jugular vein of the patient through the superior vena cava and into the inferior vena cava, providing a trocar having a lumen and a dissecting tip, inserting the trocar to enter an incision in the patient and to create a subcutaneous tissue tunnel, threading the guidewire through the lumen of the trocar so the guidewire extends through the incision, providing a dialysis catheter having first and second lumens, removing the trocar, and inserting the dialysis catheter over the guidewire through the incision and through the jugular vein and superior vena cava into the right atrium.

Dialysis catheter and methods of insertion

An apparatus for passing a guidewire through a subcutaneous tissue tunnel to enable over-the wire insertion of a catheter through the tissue tunnel. The apparatus comprises an elongated member having a distal end portion having a tip configured to advance through the tissue tunnel and an opening extending longitudinally with respect to the apparatus and dimensioned to receive the guidewire. The guidewire is inserted through the opening to pass the guidewire through the tunnel to enable subsequent insertion of the catheter.

Guidewire retrieval member for catheter insertion

A dialysis catheter comprising a first portion having a first diameter, an elongated distal portion having a second diameter smaller than the first diameter, and a transition region between the first portion and distal portion. A first longitudinally extending central lumen configured to deliver blood terminates in an opening in the distal portion. At least two independent longitudinally extending lumens are positioned radially of the first lumen, configured to withdraw blood from a patient, and terminate in a longitudinally directed opening in the transition portion.
