摘要:
A coated medical device adapted for introduction into a passage or vessel of a patient is provided. The medical device is preferably an implantable balloon with a bioactive deposited or within the balloon. The balloon can further include a hydrophilic material positioned between the balloon and a bioactive material posited on the balloon.

A branch vessel prosthesis for use with an aorta stent graft defining a lumen and having a fenestration aligned with a branch vessel, includes an expandable stent that has a tubular portion, a flareable portion, and at least one bending portion located between the tubular and the flareable portions. Upon deployment of the branch vessel prosthesis, the flareable portion is flared by bending of the bending portion.

A branch vessel prosthesis is provided for use with an aorta stent graft defining a lumen and having a fenestration aligned with a branch vessel, including a generally helical coiled stent, preferably with a graft material affixed thereto to form a branch vessel lumen. At least one full turn at the proximal end of the helical coiled stent has a diameter larger than the diameter of the fenestration so as to retain the proximal end within the aorta stent. At least two full turns of the helical coil have a diameter smaller than the at least one full coil so as to pass through the fenestration upon deployment.

A stent introducer is provided for introducing a stented catheter through a hemostatic valve. The stent introducer is inserted into the hemostatic valve to open the valve member and provide an open passageway for the stented catheter. The stent introducer is made from flexible plastic and has a slot that extends along the entire length of the stent introducer. Advantages of the stent introducer include ease of use and improved protection for the stented catheter during introduction.

A stent deployment device (110) is provided for deploying a stent in a lumen of a patient. The device can include a catheter (112), a first balloon (122) positioned near a distal end of the catheter and a second balloon (123) adjacent to the first balloon. Alternatively, the second balloon can be positioned over the first balloon. The device also includes an expandable stent (210) positioned over the first balloon and the second balloon. The first balloon comprises a semi-compliant material, a noncompliant material or a compliant material. Similarly, the second balloon comprises a semi-compliant material, a noncompliant material or a compliant material. The first balloon is expandable to a first diameter, while the second balloon can be expandable to a second diameter.
摘要:
A stent graft system for intraluminal deployment in an aorta and a branch vessel that includes an aorta stent graft for deployment within the aorta and defining a lumen for the passage of blood therethrough, and having a fenestration positioned and sized so as to allow blood to flow to a contiguous branch vessel. The system also includes a branch vessel prosthesis, preferably a stent graft, having a tubular portion and a flaring portion, such that, when deployed, the flaring portion is located within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel. A balloon expansion catheter expands the tubular portion and flare the flaring portion. The expansion of the tubular portion and the flaring of the flaring portion may occur sequentially or simultaneously.

A stent graft system for intraluminal deployment in an aorta and a branch vessel includes an aorta stent graft for deployment within an aorta and defining a lumen for the passage of blood therethrough, and having a fenestration aligned so as to allow blood to flow to a contiguous branch vessel. A branch vessel prosthesis having a flaring portion, a tubular portion and an anchoring device, are configured so that, upon deployment, the tubular portion passes through the fenestration and into the branch vessel, the anchoring device affixes the position of the tubular portion within the branch vessel, and the flaring portion is retained within the lumen of the aorta stent graft and is maintained against an inside wall of the aorta stent graft to thereby bias the aorta stent graft toward the branch vessel.

Slings, kits, and methods useful in the treatment of Obstructive Sleep Apnea (OSA) are described. An exemplary sling comprises a main body extending along a lengthwise axis and having first and second opposing ends, first and second opposing sides, and first and second opposing surfaces. Each end defines an end loop that defines a passageway extending through the main body. An exemplary method of treatment comprises creating two openings in the mandible of a patient; creating two longitudinal tunnels in the tongue of the patient; creating a transverse tunnel in the tongue of the patient; advancing a sling through the transverse tunnel; pulling each end of the sling through one of the longitudinal tunnels and through one of the openings in the mandible; pulling the tongue toward the front of the mouth or mandible; and securing the sling to a tissue to support the tongue in a new position.

Medical devices having a releasable member are described. Methods of using medical devices having a releasable member are also described. An example medical device comprises an elongate member, an intermediate member, a sheath, and a cap. Each of the intermediate member, sheath, and cap are releasably disposed on the elongate member.
摘要:
Devices and methods of identifying and treating bodily passages, such as sinus cavities, are provided. More particularly, irrigation devices and methods useful in the identification and treatment of bodily passages, such as sinus cavities, are provided. The irrigation devices comprise an elongate tubular member and an optical fiber which assist with the transcutaneous identification and/or treatment of a bodily passage.
