A suction catheter system is described with a suction nozzle that can extend from a guide catheter of the like. The suction nozzle can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. A suction lumen extends from the proximal end of the guide catheter through at least part of the guide catheter central lumen and through the suction tip. Desirable suction flow can be established using the guide lumen to facilitate the suction. Also, a delivery catheter is described with an elastic tip that can track closely over a guidewire. The elastic tip of the delivery catheter can be expanded to provide for the delivery of medical devices past the tip.

Described herein is a liquid embolic delivery device designed to minimize excess embolic solvent buildup therein. The liquid embolic delivery device generally comprises an outer catheter, an inner catheter that is longitudinally moveable within the outer catheter. The inner catheter is used for an initial embolic solvent flush and to deliver liquid embolic, while the outer catheter is used to remove excess solvent.

The plurality of nested tubes including a first tube and a second tube at least partially disposed within the first tube, the first tube and the second tube being fixed to one another through adhesive bonding. The first tube having a first bore formed in the first tube, the first bore communicating with a first gap between the first tube and the second tube, and an adhesive is provided in the first gap.

Telescoping catheters for selectively moving a component of a medical device system are disclosed. An illustrative telescoping catheter may comprise a proximal hub adjacent a proximal end of the catheter, a drive cable, and a telescoping section extending from a proximal end adjacent the proximal hub to a distal end. The telescoping section may comprise an intermediate sheath having a proximal end coupled to the proximal hub and extending distally to a distal end, an outer sheath disposed over the intermediate sheath, the outer sheath having a proximal end and a distal end, an inner sheath disposed within the intermediate sheath, the inner sheath having a proximal end and a distal end, and a seal member disposed between the intermediate sheath and an outer surface of the inner sheath. The intermediate sheath may be configured to be longitudinally displaced relative to the inner and outer sheaths.

A fluid transfer device for needle-free delivery of a probe to a patient's vascular system, the device including an introducer body and an actuator. The actuator is linearly displaceable along at least a portion of the introducer body, and the actuator is operably coupled to the probe to advance and retract the probe based on direction of displacement of the actuator. The device also includes a connector member positioned proximate a distal end portion of the introducer body and configured for releasable connection to at least one surface of an access connector. The device also includes a locking member configured to prevent disconnection of the connector member from the access connector when the actuator is advanced to a first position, and to allow disconnection of the connector member when the actuator is retracted to a second position along the introducer body.

A fluid transfer device including a housing, a distal introducer portion configured to penetrate a needleless access connector of a vascular access device, and a wheel member rotatable with respect to the housing and operably coupled to a probe to advance and retract the probe through the distal introducer portion. The fluid transfer device also includes a connector member positioned proximate the distal introducer portion, wherein the connector member includes a pair of opposing distal clip portions, a pair of opposing proximal clip portions, and a locking member. The locking member is operably coupled to the wheel member and is configured to prevent actuation of at least a portion of the connector member when the wheel member is rotated to a first position and to allow actuation at least a portion of the connector member when the wheel member is rotated to a second position.

The subject guide catheter extension/pre-dilatation system includes an outer delivery sheath, an inner member extending within the sheath, and a mechanism for engagement/disengagement of the inner member to/from the sheath. The inner member is configured with a tapered distal tip having a delivery micro-catheter and a pre-dilatation balloon member attached to the tapered distal tip in proximity to the micro-catheter. The outer delivery sheath and the inner member are modified for different engagement/disengagement mechanisms operation. The delivery micro-catheter provides for an improved crossability for the balloon member to the treatment site in an atraumatic, expedited and convenient fashion. During the cardiac procedure, a guidewire and a guide catheter are advanced to the vicinity of the treatment site within a blood vessel. Subsequent thereto, the inner member and outer delivery sheath, in their engaged configuration, are advanced along the guidewire inside the guide catheter towards the site of treatment. Once at the treatment site, the balloon member is inflated for pre-dilatation treatment. Subsequently, the inner member is disengaged and retracted from the outer delivery sheath, and a stent is delivered to the treatment site inside the outer delivery sheath.

A lavage catheter for the treatment of a maxillary sinus is described. The catheter comprises a proximal portion and a distal portion. The distal portion comprises an irrigation tip. The irrigation tip has a tip opening through which fluid may be delivered by one handed operation of the catheter. A method for lavaging the maxillary sinus includes inserting the lavage catheter into a patient's anatomy and advancing the irrigation tip into the maxillary sinus using one hand.

The invention relates to a puncture system having an outer tubular body which is designed to remain in a body part of a living being, said puncture system comprising at least one inner tubular body and a puncture needle, wherein the inner tubular body is guided through a working lumen of the outer tubular body and is longitudinally displaceable relative to the outer tubular body, and the puncture needle is guided through a puncture lumen of the inner tubular body and the inner tubular body is longitudinally displaceable relative to the puncture needle. The puncture system has a manually actuatable element that can be moved by manual actuation at least into a fixing position and into a release position, wherein, in the fixing position, the longitudinal displaceability a1) of the inner tubular body relative to the outer tubular body and/or a2) of the puncture needle relative to the inner tubular body and/or a3) of the puncture needle relative to the outer tubular body is removed or reduced.

A smart obturator assembly includes a hub forming a central passage. The hub is configured to couple to a proximal end of a device that forms a lumen such that the central passage is in fluid communication with the lumen. A collar on the hub includes electronic circuitry in signal communication with remote reception circuitry. An obturator is movably positionable within the lumen. The obturator is movable within the lumen between a first position and a second position. The obturator includes a distal end and a sensor at the distal end. The sensor is configured to sense an environmental characteristic within a patient’s blood stream, generate a signal representative of the environmental characteristic, and transmit the signal to the electronic circuitry. The electronic circuitry is configured to receive the signal and transmit the signal to the remote reception circuitry.
