Abstract:
A medical implant made from multiple layers of non-synthetic, natural tissues is provided. The medical device includes openings that extend radially through the wall of the medical implant. One advantage of the medical implant is that a synthetic support structure is not needed. As a result, problems associated with implanting a foreign material into a body may be avoided.
Abstract:
An intraluminal prosthesis (20) for strengthening a main lumen and a branch lumen in direct fluid communication with the main lumen includes a tubular graft (20) and a flexible stent (210). The tubular graft includes a flexible body having a wall with a fenestration (17). The flexible stent (210) includes a body with at least one open space to encourage tissue prolapse. The flexible stent (210) may be configured for intraluminal coupling to the fenestration (17) of the tubular graft, so that the entire prosthesis may be assembled and anchored into a main lumen and a branch lumen with a minimally invasive procedure. The open space or spaces can encourage tissue prolapse, which may act to anchor the flexible stent (221 ) to the branch lumen.
Abstract:
In at least one embodiment of the present invention a balloon catheter is provided. The balloon catheter comprises a shaft having a lumen formed therethrough. Connected to the shaft is an inflatable balloon. The inflatable balloon has a balloon wall defining a balloon interior surface and a balloon exterior surface that is opposite the interior surface. In fluid communication with the balloon wall is the lumen for inflating the balloon to define an inflated state and for collapsing the balloon to define a deflated state. The balloon wall is textured in the deflated state such that the balloon interior surface is spatially registered with the balloon exterior surface. The balloon in the inflated state is tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state.
Abstract:
A system and method for repairing one or more vessels includes a branch vessel prosthesis (11) for use with an aorta stent graft (1) defining a lumen and having a fenestration (7) aligned with a branch vessel. The branch vessel prosthesis includes a flaring portion (36) and a tubular portion (33), where the flaring portion is retained within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel.
Abstract:
An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis (11 ). The branch vessel prosthesis (11 ) is deployable within a branch vessel body lumen and comprises a stent (48) having a generally tubular body portion (33), a flareable proximal end portion (36), and a coupling portion (38) disposed intermediate the body portion and the flareable portion. The coupling portion is preferably more crush-resistant than the body portion.

Abstract:
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.
