A blood pump assembly can include various components such as a housing and a sensor configured to detect one or more characteristics of the blood. In some embodiments, the sensor can be coupled to the housing and can include a sensor membrane configured to deflect in response to a change in a blood parameter (e.g., pressure). The blood pump assembly can include a shield that covers at least a portion of the sensor membrane so as to protect the sensor from damage when the blood pump assembly is inserted through an introducer and navigated through the patient's vasculature and/or when the blood pump assembly is inserted into the heart in a surgical procedure. One or more protective layers can be deposited over the sensor membrane to prevent the sensor membrane from being dissolved through interactions with the patient's blood.

The present invention is a collapsible blood filter for use during a vascular procedure, such as angioplasty or stent deployment. A filter made of braided filaments is located on the distal end of a delivery member, and the filter is deployed downstream of the vascular treatment site to capture emboli released during and immediately after the procedure. Optimal braid geometry of the filter ensures that captured emboli will be retained during collapse and removal of the filter following the procedure.

A hub for connecting a medical catheter in fluid communication with a medical device, such as a syringe, includes a tubular shaped body member which has an outer surface that is formed with a plurality of grips. The hub also has a pair or diametrically opposed wings which extend from the outer surface of the body member and it has a proximal end which is formed as a female luer fitting for engagement with the medical device. The distal end of the hub is formed with a spiral strain relief element having a passageway which receives the proximal end of the medical catheter. In operation, the spiral relief element supports the medical catheter and prevents kinking of the catheter near the hub during flexure of the catheter by providing for a progressive transition from the relative rigidity of the hub to the flexure required by the catheter.

A stent/graft catheter delivery handle comprising a housing and a trigger pivotally connected to the housing on one end of the trigger. Squeezing the free end of the trigger towards the handle housing shifts a pawl, which is engaged with grooves on the outer surface of a stent/graft delivery catheter, longitudinally along the length of the catheter. Shifting of the pawl has the effect of retracting the sheath of the catheter relative to the plunger (inner lumen assembly) of the catheter and thus deploying a stent/graft stored in a proximal end of the catheter.
