A guidewire management device, a method of manufacturing the guidewire management device and a method for guidewire management are disclosed. The guidewire management device includes a housing through which a lumen of a catheter passes; and a locking mechanism mounted within the housing; wherein the locking mechanism is configured to lock the housing if a guidewire is present in the lumen and to unlock the housing if the guidewire is absent from the lumen. In one embodiment, the locking mechanism comprises a lever structure comprising a first arm connected to a second arm, wherein the first arm is configured to abut the lumen such that it becomes displaceable from a first position to a second position and actuates the second arm to engage a latch member to lock the housing if the guidewire is inserted through the lumen. Conversely, the housing unlocks if the guidewire is removed from the lumen.

A steerable transseptal punch system and method of using the steerable transseptal punch system to access the left atrium.

The subject guide catheter extension system with a micro-catheter delivery catheter includes an outer sheath, an inner member extending within the sheath, and a mechanism for engagement/disengagement of the inner member to/from the sheath. Several mechanisms of engagement/disengagement between the inner and outer members are provided including a friction mechanism, threaded mechanism, pull away sheath, and engagement/disengagement mechanism for pusher's handles. The sheath and the inner member are modified for different engagement/disengagement mechanisms operation. A micro-catheter delivery system provides for an improved atraumatic crossability to the treatment site in an expedited and simplified fashion. During a procedure, a guidewire along with a guide catheter are advanced to the vicinity of the treatment site within a blood vessel. Subsequent thereto, the subject guide catheter extension system is manipulated to advance the micro-catheter along the guidewire inside the guide catheter towards and beyond the site of interest. Once the micro-catheter is in place, the outer sheath slides along the micro-catheter until reaching the lesion, and then the inner member is removed from the sheath, and the sheath then is ready for passing the treatment catheter (stent/balloon) towards the lesion to be treated.

A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. The handle has a proximal end, a distal end and a longitudinal axis along the length of the handle. The grooming sheath has a distal end and a proximal end with the proximal end of the grooming sheath being attached to the distal end of the handle. The rail has a distal end and a proximal end and disposed partially within the grooming sheath to define an annular lumen is between the rail and the grooming sheath. The guide wire operatively extends from the distal end of the rail and the balloon catheter is disposed at least partially in the handle and annular lumen. The balloon catheter movement mechanism operatively disposed on the handle and configured for advancement and retraction of the balloon catheter through both the handle and the annular lumen and along both the rail and guide wire by user operation of the balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy and then positioning a guide wire operatively extending from a rail of a medical device into a sinus opening of the patient. The method further includes advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire. The method also includes treating the sinus opening via inflation of the balloon catheter. In the method, the annular lumen is between the rail and a grooming sheath of the medical device and the advancing is accomplished via user operation of a balloon catheter movement mechanism of the medical device.

Disclosed are compact rapidly insertable central catheter (“RICC”) insertion assemblies and methods. For example, a RICC insertion assembly can include a RICC, an introducer assembly, an access guidewire, and a coupler coupling together the RICC and the introducer assembly. The RICC can include a catheter tube, a catheter hub, and one or more extension legs connected in the foregoing order. The introducer assembly can include an introducer needle coupled to a syringe. The introducer needle can include a needle-hub through hole passing through a needle hub and connecting to a needle-shaft lumen of a needle shaft. The access guidewire can include a proximal portion disposed in the RICC and a distal portion disposed in the needle-shaft lumen through the needle-hub through hole. The coupler can enforce a loop in the access guidewire over which the catheter tube follows, thereby compacting the RICC insertion assembly and making it easier to handle.

A sterile barrier for a robotic drive comprises a first drive module configured to move moving along a longitudinal axis of a drive body. The sterile barrier comprises a first resilient member having a first free edge proximate the longitudinal axis. The first free edge adjacent the first drive module is resiliently biased away from and returned to the longitudinal axis as the first drive module moves along the longitudinal axis.

A robotic drive system for driving one or more elongated medical devices includes a robotic drive including a first drive module; and a second drive module proximal to the first drive module each drive module independently moved along a longitudinal axis of the robotic drive. A sterile cassette assembly includes a first cassette; and a second cassette coupled to the first cassette with a coupler. The first cassette and the second cassette are removably attached together to the first drive module and the second drive module respectively.

Disclosed are introducer adapters, introducer assemblies, and methods. In an example, an introducer assembly can include a syringe, a needle, and an introducer adapter fluidly coupled therebetween. The introducer adapter can include a primary conduit, a secondary conduit extending from a side of the primary conduit, and a valve including an elastomeric septum sealing a proximal portion of the primary conduit or the secondary conduit. An access guidewire is optionally loaded in the introducer adapter and sealed therein by the valve. In another example, a method can include a method for securing vascular access with the foregoing introducer assembly. Such a method can include obtaining the introducer assembly, establishing a needle tract from an area of skin to a blood-vessel lumen of a patient with the needle, and advancing at least a guidewire tip of the access guidewire into the blood-vessel lumen for the securing of the vascular access.

A catheter delivery device includes a hollow longitudinal body, a fluidic bypass, and a hemostasis valve. The hollow longitudinal body includes a clamping portion and a guide catheter. The guide catheter has a distal end for access into a vessel of a patient and a proximal end coupled to the clamping portion. The clamping portion has a distal end coupled to the guide catheter, a proximal end coupled to the hemostasis valve, and a guidewire securing section. When the guidewire securing section of the clamping portion is securing the guidewire, the fluidic bypass maintains fluid communication between the guide catheter and the hemostasis valve. In some cases, the guidewire securing section and the fluidic bypass are separated by material within the hollow longitudinal body. In some cases, the fluidic bypass is separate from the guidewire securing section outside of the hollow longitudinal body.

A medical tool gripper for gripping a long medical tool includes a substantially hollow cylindrical main body and a fixing tool for fixing a medical tool to the main body. The main body has a main body inner space that extends over the entire longitudinal direction of the main body and in which the medical tool can be arranged, and a main body groove that is open on the outer periphery of the main body and communicates with the main body inner space over the entire longitudinal length of the main body. The main body groove includes a distal end portion including the distal end of the main body groove, and a proximal end portion including the proximal end of the main body groove and having an opening at a different position from an opening of the distal end portion in the circumferential direction of the main body.
