摘要： A sheath assembly includes a first sheath, a second sheath, and an attachment mechanism. The first sheath includes a first sheath inner surface defining a first sheath lumen extending along a first sheath central longitudinal axis between a first sheath first end portion and a first sheath second end portion. The second sheath includes a second sheath inner surface defining a second sheath lumen extending along a second sheath longitudinal axis between a second sheath first end portion and a second sheath second end portion. The attachment mechanism couples the second sheath to the first sheath. The attachment mechanism includes an attachment mechanism step-up dilation. At least a portion of the attachment mechanism is asymmetrical, at the attachment mechanism step-up dilation, about the first sheath central longitudinal axis.

摘要： An stent delivery system may include a delivery device and a tubular body having a lumen sized to slidably fit about an outer diameter of the delivery device and a drainage stent having an anchoring mechanism, wherein the delivery device includes a constraining member configured to engage an external portion of the tubular body at the proximal end of the delivery device. A method of delivering a stent may include inserting a tubular body into the port of an endoscope, inserting a stent delivery device and a stent having an anchoring mechanism into the tubular body, wherein the delivery device includes a constraining member configured to engage and retain the tubular body at the proximal end of the delivery device, advancing the drainage stent distally through the tubular body, sliding the tubular body proximally, and engaging an external portion of the tubular body with the constraining member.

摘要： 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.

摘要： An access device for placing a medical article within a body space includes a needle, a dilator, and a sheath. The dilator can be coaxially and slideably disposed about the needle, and the sheath can be coaxially and slideably disposed about the dilator. The access device can further include a inner member coaxially disposed between the needle and dilator. The needle can include a fenestration in fluid communication with a space between the needle and inner member. When the needle punctures a blood vessel, the fenestration allows blood to flow into the space between the needle and inner member to provide a visual indicator to a physician or healthcare professional that the needle is in a vessel.

摘要： A telescoping catheter including an elongated tubular member having a proximal end, a distal end, and a passageway extending between the proximal end and the distal end. The tubular member includes a first tubular segment and a second tubular segment. The first tubular segment and the second tubular segment are slidable relative to one another to vary a length of the tubular member. The first tubular segment includes a first connector mateable with a second connector of the second tubular segment to selectively maintain the first and second tubular segments in an extended position. The second tubular segment includes a second proximal end that is mateable with a handle.
