Abstract
Disclosed are puncture sealing systems and methods of locating a puncture site within a vessel. The systems can include puncture locating dilators and access sheaths that are configured to locate the puncture site within a vessel so that the position of the puncture site relative to a distal end of the access sheath is known during a puncture sealing procedure.
Core Innovation
The invention is a vascular location system comprising a dilator and an access sheath used to determine depth information during insertion into a puncture. The dilator has a distal end and a proximal end along a longitudinal direction, an inlet hole spaced from the distal end, an outlet hole in fluid communication with the inlet hole, and a first plurality of markings disposed between the inlet and outlet holes along the longitudinal direction. The access sheath has a distal end and a proximal end along the longitudinal direction and a second plurality of markings disposed between the distal and proximal ends, with the second plurality corresponding to the first plurality so that depth can be indicated for both components.
The first plurality of markings of the dilator correspond to the second plurality of markings of the access sheath, and the markings are indicative of the depth the dilator is inserted into a puncture and the depth that the access sheath is inserted into the puncture. This correspondence enables the insertion depths of the dilator and sheath within the puncture to be identified using the respective corresponding markings along their longitudinal directions.
In embodiments, the dilator includes a guide channel configured to receive a guide wire as the dilator is inserted into the puncture. The inlet hole and outlet hole provide fluid communication through the guide channel such that blood entering the inlet hole flows through the guide channel and exits through the outlet hole connected to the same guide channel.
Additional embodiments include a vascular closure device insertable through an access channel of the sheath body and positioned so a distal portion lies beyond the sheath distal end, with the closure device including an internal lumen sized to receive and surround a guide wire and allow the closure device to slide along the guide wire.
Claims Coverage
The independent claims include one main independent claim reciting a vascular location system with depth markings that correspond between a dilator and an access sheath, and dependent refinements that add structure and depth, flow, and closure positioning features.
Corresponding longitudinal depth markings
The dilator includes a first plurality of depth markings and the access sheath includes a second plurality of depth markings corresponding to the first plurality so that the dilator depth and the access sheath depth are indicated within a puncture.
Numeric depth markings
Both the dilator first plurality of depth markings and the access sheath second plurality of depth markings are composed of numbers.
Dilator guide channel for guide wire reception
The dilator includes a guide channel running from the distal to proximal end and configured to receive a guide wire as the dilator is inserted along the guide wire into the puncture.
Blood fluid communication via inlet and outlet through the guide channel
Blood entering an inlet hole flows through a guide channel and exits through an outlet hole connected to the same guide channel.
Visual tracking depth markings relative to skin surface
The dilator includes multiple depth markings configured to let a user visually track the depth of a puncture in a vessel relative to the patient's skin surface.
Guide-wire sliding and lumened vascular closure device
A vascular closure device is insertable through the sheath body access channel and positioned so its distal portion lies beyond the sheath distal end, with an internal lumen sized to receive and surround a guide wire and allow the closure device to slide along the guide wire.
Overall, the claim coverage centers on a depth-indicating vascular location system where dilator and sheath markings correspond to indicate insertion depth into a puncture, optionally using a guide channel and guide wire. Dependent features further define numeric and visually trackable markings, blood flow communication via inlet and outlet holes through a guide channel, and integration of a vascular closure device that uses an internal lumen to slide along a guide wire positioned beyond the sheath distal end.
