Abstract
The present invention relates generally to systems and methods for delivering embolic devices into a body lumen of a patient. These embolic devices are applicable to a variety of neurological and/or peripheral applications. In particular, the embolic devices may be used to occlude a vessel within a patient, and/or to treat aneurysms, arteriovenous malformations, traumatic fistulas, uterine fibroids or cancer.
Claims20
A system for treating a patient, comprising:
- a catheter having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end;
- a delivery wire slidably disposed within the lumen, the delivery wire having a proximal end and a distal end;
- and
- an embolic device having a proximal and a distal end, wherein
- (a) the proximal end of the embolic device includes a structure expandable between first and second positions relative to the distal end of the catheter,
- (b) the distal end of the delivery wire includes a head with a helical groove on the outer surface of the head configured for enhanced engagement with the structure,
- (c) the structure interfits with the head when in the first position, and
- (d) the structure assumes the second position when the proximal end of the embolic device is positioned distally to the lumen of the catheter.

A system for treating a patient, comprising:
- a catheter having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end;
- a delivery wire slidably disposed within the lumen, the delivery wire having a proximal end and a distal end;
- and
- an embolic device having a proximal end and a distal end, wherein
- (a) the proximal end of the embolic device includes a plurality of arms expandable between first and second configurations,
- (b) the distal end of the delivery wire includes a head with a helical groove on the outer surface of the head configured for enhanced engagement with the plurality of arms,
- (c) the arms form an interference fit with the head when in the first configuration, and
- (d) the arms assume the second configuration when the proximal end of the embolic device is positioned distally relative to the catheter lumen.
5 more elements
A method of treating a patient, comprising:
- inserting a system comprising a catheter, a delivery wire and an embolic device into a body lumen of a patient;
- positioning a distal end of the catheter at a position within the body lumen where embolization is required;
- and
- moving the catheter relative to the delivery wire so that a distal end of the delivery wire exits a lumen of the catheter, thereby releasing a proximal end of the embolic device from a distal end of the delivery wire.
