摘要:
A fluid-based anastomosis system, including a body, a fluid power source, an actuator powered by said source and at least two elements coupled to said actuator and adapted to perform at least two different relative motions, responsive to serial powering of said actuator.
摘要:
A leg compacting system for compacting inwards a group of legs (228) of an anastomotic connector towards a central location thereof, comprising, a coupler for coupling to a delivery system on which said connector is mounted; and a plurality of leg confiners (820), said leg confiners (820) configured to selectively move in an inwards direction and said confiners configured to have a resting compacted configuration in which a space of between 7 and 1 mm in width is maintained between the innermost leg contacting sections of said confiners such that a graft vessel suitable for mounting on said connector can be passed between said confiners (820).
摘要:
Hole-forming apparatus (1900) for forming a hole in a blood vessel, comprising a penetration shaft (1908), having a tip (1904) adapted to be inserted through a wall of a blood vessel; a tissue holder (1986), configured to hold a portion of said wall, said holder (1986) being activated to perform said holding separately from an insertion of said penetration shaft (1908) through said wall; and a cutting surface (1910) adapted to cut through the wall.
摘要:
An anastomotic connector (200) for attaching two blood vessels comprising a plurality of eye segments (1604), each defining a channel and each including a part of an interlock mechanism (1600) on said channel; a plurality of hook segments (1602), each defining a tissue holding area, each adapted to pass through said channel and including a second part of said interlock mechanism (1600), wherein, said interlock mechanism (1600) engages for a hook and an eye segment when said hook segment (1602) is retracted back into said eye segment (1604) enough to attach two layers of vascular tissue between said eye segment (1604) and said hook segment (1602).
摘要:
A system including a positioning member (10) including a flexible member (12) which is reversibly deformable between a first deployment configuration and a second deployment configuration, at least one vasculature abutment member (40) located on the flexible member (12) for abutting against structure (17) in a vasculature of a patient, and a delivery system (22) connected to the positioning member (10) for delivering the positioning member (10) to the structure (17) in the vasculature of the patient and for deforming the flexible member (12), wherein in deforming between the deployment configurations, the flexible member (12) undergoes eversion.
摘要:
A scaffold is mounted on a balloon of a balloon catheter. The scaffold has closed cells which deform upon balloon expansion and generate forces that cause struts or other components of the scaffold to deflect outwardly to a diameter that is greater than the inflated diameter balloon. The deflected struts apply forces to fracture plaque of other hardened lesions and also form an annular gap surrounding the balloon to provide for bypass flow of blood or other body fluids. A sheath may be located over the deflected struts to protect adjacent tissue structures from the deflected struts and/or to further define the gap.
