  • Patent number: 7326230
    Abstract: An improved device for closing an opening in a blood vessel includes a cannula holding a first wire group, a second wire group, and a wire fixation device. The positions of the first wire group and second wire group are independently adjustable. The first wire group is deployed from the cannula into an interior region of the blood vessel and retracted to a desired position in contact with an intimal surface of the blood vessel around the opening. The second wire group is deployed from the cannula and moved to a desired position in contact with an adventitial surface of the blood vessel around the opening. The fixation device is adapted to affix the first and second wire groups in their desired positions to thereby effectuate closure of the opening in the blood vessel.

  • Patent number: 7322957
    Abstract: An angioplasty device and particle trap for use in removal of a particle from a small diameter vessel or vessel-like structure is disclosed. One embodiment includes a catheter for insertion into a vessel-like structure, the catheter having a catheter wall and a movable member, a trap operably connected to the catheter wall and to the movable member, wherein relative motion between the catheter wall and the movable member actuates the trap. In one embodiment, the expanded trap is formed from struts in a spiral-shaped configuration. In one embodiment, the contracted trap forms a waist to creates a pinch-point to trap particles. In one embodiment, the contracted trap forms a cocoon-like structure to further trap particles. In one embodiment, the angioplasty device includes a handle to actuate the trap from a contracted position to an expanded position and return to a contracted position. The handle provides rotational or longitudinal or both types of movement to actuate the trap.

  • Patent number: 7322988
    Abstract: A catheter can be formed from an elongate shaft and a distal tip. The catheter can be formed by flaring a proximal end of the distal tip to form a flared proximal end and positioning the distal tip such that the flared proximal end of the distal tip overlaps a distal end of the outer layer. Heat and pressure are applied to melt and flow together a portion of the outer layer proximate the distal end of the shaft and the overlapped portion of the flared proximal end of the distal tip, thereby forming a joint between the elongate shaft and the distal tip.

  • Patent number: 7323002
    Abstract: An emboli extraction catheter and vascular filter system comprising a guidewire, a vascular filter attached near the distal end of the guidewire, and an emboli extraction catheter. The vascular filter has a smaller first diameter for insertion into the lumen of a vessel, and a second larger diameter for expanding to substantially equal the diameter of the lumen and to be placed in generally sealing relationship with the lumen. The emboli extraction catheter is a flexible catheter comprising a hub attached to the proximal end of the catheter. The hub further comprises a sideport and means for maintaining a seal on the guidewire. The emboli extraction catheter can be used to aspirate embolic particulates, so as to avoid their accidental release after they are captured in a vascular filter, and can also be used to empty full vascular filters of embolic particulates which may block distal flow.

  • Patent number: 7320694
    Abstract: The present invention provides an obturator tip having a rigid, elongated, distal section having a blunt, rounded, distal end designed to separate tissue. The distal section is connected to a proximal section by a central section having tapered outer surfaces. The obturator tip of the present invention is equipped with arc shaped blades positioned on opposite sides of the tip and 180 degrees apart from each other. In one embodiment, the arc shaped blades are positioned rearwardly with respect to the distal section of the obturator. This feature of the present invention allows the elongated distal section to create a small, non-cutting tissue separating track prior to blade contact with the patient.
