A catheter securement device which automatically deploys one or more sutures to secure a catheter without requiring the practitioner to manually suture the catheter to the self-suturing anchor device. A ratchet mechanism having one or more rotatable ratchet members, which pivot, and a ratchet member engagement spring, which maintains contact between the teeth of the rotatable ratchet member and the teeth of the ratchet ring. A suture retention assembly is provided to maintain the position of the sutures to minimize disruption of the sutures before deployment of the sutures.

A hemostasis valve apparatus includes (i) a valve body having a lumen therethrough; (ii) a first resiliently deformable seal disposed within the valve body; and (iii) a plunger having a lumen extending therethrough. A passageway extends through the lumens of the plunger and valve body. A cap movably coupled to the valve body selectively moves the plunger along the valve body, thereby selectively compressing the seal. A connector coupled to the plunger is configured to couple the plunger in fluid communication with a fluid delivery means for delivering fluid to the valve. The valve has a substantially linear configuration for convenient storage and use. The valve also features a second seal for sealing the passageway extending through the lumens.

A rotatable connector having an enlarged annular flange positioned at the distal end of a tubular body. An annular cap having an aperture is received on the tubular body through the aperture so as to rotatably encircle the tubular body proximal of the retaining flange. A split ring rotatably encircles the tubular body between the retaining flange and the cap. The split ring has an inner diameter smaller than the outer diameter of the retaining flange and an outer diameter larger than the inner diameter of the aperture of the cap. An access chamber positioned at the proximal end of a tubular hub receives the distal end of the tubular body in mating relationship to enable the proximal end of the hub to be ridgedly coupled to the cap. A transfer duct communicating with the access chamber in the tubular hub is rotatably fluid coupled with the passage in the tubular body.

A valve system configured to access the cardiovascular system of a patient includes: (i) a valve body having a lumen therethrough; (ii) a selectively openable resilient first seal, (iii) a compressible second seal including an opening which communicates with the lumen when the second seal is in an open position; (iii) a locking nut movably coupled to the valve body, the locking nut configured to selectively increase and decrease compressive force on the second seal; and (iv) an introducer configured to selectively open the resilient first seal. The introducer has a proximal end and a distal end. The introducer is movably coupled to the locking nut and reciprocates between a first position and a second position within the locking nut. The resilient first seal is in the closed position when the introducer is in the first position and the resilient first seal is in the open position when the introducer is in the second position. The introducer protects elongate instruments such as catheters having stents thereon while the instruments are moved through the resilient seal while the seal is opened by the introducer.

An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for monitoring, displaying and optionally recording inflation or deflation data when the syringe system is used to inflate or deflate the balloon of the catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger toward the rear of the barrel. A piezoresistive semiconductor transducer placed in fluid communication with the fluid pressure applied by the syringe, senses the fluid pressure and outputs an electrical signal representative of that pressure. The electric signal is input to a controller where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that fluid pressure is applied. The electronic data representing this information is displayed and optionally recorded.

A positioning apparatus having a cylindrical shaft including a retaining shaft, an expansion shaft, and a frustoconical transition shaft extending therebetween. The expansion shaft has a recess sized to receive a flange radially extending outward on an elongated member. The shaft is configured to be received within a housing having a passageway extending therethrough. The passageway is defined by an interior surface which includes a cylindrical first surface positioned at the top of the housing. The first surface has in inner diameter equal to the outer diameter of the split ring. The interior surface also includes a frustoconical constriction surface positioned at the bottom end of the housing. The housing raises and lowers relative to the shaft for positioning the split ring onto the elongated body under the force of a weight.

Guidewire holders to store one or more coiled guidewires substantially immersed in a storage fluid are provided. Some embodiments are more suited to storing a single guidewire holder while other embodiments are designed specifically to hold a plurality of guidewires. The guidewire holder is generally configured as a shallow pan in a circular or ovoid shape with a periphery to hold the coiled guidewires. At least a portion of the guidewire holder is shaped so that the coiled guidewire is held away from at least the outer periphery of the holder. This enables a healthcare professional to reach into the guidewire holder and grasp a portion of the guidewire in order to easily extract the coiled guidewire from the holder.

The present invention is directed towards a side port for an introducer sheath which precludes the inadvertent excursion a guide wire (or other article or material) through a side port while advancing through the main lumen of an introducer sheath. To prevent inadvertent excursions of a guide wire, the introducer sheath has one or more non-circular side ports. The non-circular component of the side port has a minimum transverse dimension that is smaller than the diameter of the guide wire to be introduced through the lumen of the introducer sheath. Therefore, the small diameter of the non-circular component of the side port prevents a guide wire from inadvertently entering the side port.
