Abstract
In an example, a scoring device is configured for retention of a catheter shaft. The scoring device incudes a proximal portion and a distal portion. A retention sleeve extends between the proximal and distal portions. The retention sleeve has a catheter socket configured to selectively receive and mechanically engage the catheter shaft. The scoring device includes a scoring tool coupled with the retention sleeve, for instance proximate to the distal portion. The scoring tool includes a balloon socket configured to selectively receive a balloon of the catheter shaft. The scoring tool includes one or more scoring elements extending around the balloon socket, the one or more scoring elements configured to provide localized scoring to vasculature.
Core Innovation
The invention provides a system including a scoring device configured for retention of a catheter shaft of a catheter. The scoring device includes a proximal portion and a distal portion including a distal tip, with a retention sleeve extending between the proximal and distal portions. The catheter shaft extends from a distal end to a proximal end, where the distal end has an inflatable balloon and the proximal end has a hub configured to operate the catheter.
The retention sleeve has a catheter socket configured to selectively receive and mechanically engage the catheter shaft. The retention sleeve is configured to extend from a shaft distal end to proximate the hub of the catheter shaft, so that the catheter shaft is received in the catheter socket. Mechanical engagement of the catheter socket statically secures the retention sleeve to the catheter shaft and constrains longitudinal movement of the catheter shaft along a longitudinal axis of the retention sleeve.
A scoring tool is coupled with the retention sleeve proximate to the distal portion and located distally with respect to the retention sleeve. The scoring tool includes a balloon socket configured to selectively receive the balloon of the catheter shaft, and one or more scoring elements extending around the balloon socket to provide localized scoring to vasculature. The scoring tool and balloon configurations change from a deflated state to an inflated state to provide localized scoring while maintaining conformance through corresponding tool and balloon profile change.
Claims Coverage
Two independent claims are identified (clm-00001 and clm-00021). Across both independent claims, the claims include a catheter retention sleeve/socket with a coupled scoring tool having a balloon socket and one or more scoring elements configured to provide localized scoring to vasculature.
Retention sleeve with catheter socket for mechanical engagement
A retention sleeve extending between the proximal and distal portions, the retention sleeve having a catheter socket configured to selectively receive and mechanically engage the catheter shaft, wherein the retention sleeve is configured to extend from a shaft distal end to proximate the hub of the catheter shaft.
Scoring tool with balloon socket and circumferential scoring elements
A scoring tool coupled with the retention sleeve proximate to the distal portion and located distally with respect to the retention sleeve, the scoring tool including a balloon socket configured to selectively receive the balloon of the catheter shaft and one or more scoring elements extending around the balloon socket, the one or more scoring elements configured to provide localized scoring to vasculature.
Static securing of the retention sleeve to constrain longitudinal movement
Wherein the catheter shaft is received in the catheter socket, and mechanical engagement of the catheter socket with the catheter shaft statically secures the retention sleeve to the catheter shaft to constrain longitudinal movement of the catheter shaft along a longitudinal axis of the retention sleeve.
Balloon and scoring tool profile change between deflated and inflated configurations
A balloon in a balloon socket whose balloon profile and the associated scoring tool profile change between a deflated state and an inflated state, with the inflated balloon profile being larger than the deflated balloon profile.
Initial and expanded scoring tool profiles
The scoring tool has an initial configuration with a first tool profile and an expanded configuration with a second tool profile larger than the first tool profile.
The independent claim coverage focuses on retaining a catheter shaft using a retention sleeve with a mechanically engaging catheter socket, and providing localized vasculature scoring using a coupled scoring tool with a balloon socket and scoring elements around the balloon socket. Dependent refinements described in the partial record further constrain the retention structure and specify profile changes between deflated and inflated configurations, including initial and expanded scoring tool profiles.
