摘要： A low profile, two lumen dilator is provided for an arteriotomy closure system. The dilator includes a first lumen adapted to receive a guidewire and a second lumen having a proximal segment that defines a blood marking lumen and a distal segment that receives the distal ends of stabilizers in a common pocket. The blood marking lumen and pocket are arranged in tandem. The guidewire lumen may extend the full length of the dilator or may be shortened to provide rapid exchange capability.

摘要： An arteriotomy closure system includes a double barrel sheath having parallel dedicated lumens that merge at a distal juncture into a single common lumen. One of the dedicated lumens receives a dilator and the other a stapler. One of the dilator or stapler can be advanced from its dedicated lumen distally through the common lumen and beyond the distal end of the sheath while the other of the dilator or stapler is retracted into its dedicated lumen.

摘要： Medical vascular catheters adapted to be inserted into a blood vessel from an incision through the skin of a patient for introducing other devices or fluids for diagnostic or therapeutic purposes into the patient's vasculature and manufacturing methods are disclosed. The catheters have a unitary catheter hub and strain relief formed at the proximal end of the catheter body for attachment to other apparatus and for inhibiting kinking of the catheter body. The unitary catheter hub and strain relief is formed of a proximal hub portion and a distal strain relief coil surrounding the catheter body in a catheter hub/body junction. The distal strain relief coil is shaped as a distally tapered, single coil to provide distally increasing flexibility and uniform bending characteristics in 36.degree. around the circumference of the catheter body received within the within the strain relief coil lumen. The strain relief coil is optionally formed with blends of materials selected to distally increase the distal strain relief bending flexibility.
