Abstract
A delivery device configured to deliver a medical device into a patient is provided. The delivery device includes a distal ring and a transition tunnel. The transition tunnel is sized to receive a medical device. The transition tunnel is coupled to the distal ring. The delivery device also includes a proximal chute that has an inner perimeter and an outer perimeter. The inner perimeter of the proximal chute is coupled to the transition tunnel. The proximal chute is configured to transition between opened and closed conditions. The outer perimeter of the proximal chute in the opened condition is spread radially outward from the transition tunnel and defines an opening for receiving the medical device. The proximal chute in the closed condition is configured to at least partially prevent the medical device from egressing the delivery device.
Core Innovation
The invention provides a delivery device configured to deliver a medical device into a surgical skin pocket. The delivery device includes a distal ring, a transition tunnel sized to receive the medical device, and a proximal chute. The transition tunnel is coupled to the distal ring, and the proximal chute includes an inner perimeter and an outer perimeter with the inner perimeter coupled to the transition tunnel.
The proximal chute transitions between opened and closed conditions. In the opened condition, the outer perimeter of the proximal chute is spread radially outward from the transition tunnel and defines an opening for receiving the medical device. In the closed condition, the proximal chute at least partially prevents the medical device from egressing the delivery device.
To maintain the closed condition and secure the reduced opening, the delivery device includes at least one flexible loop attached to the outer perimeter of the proximal chute. A cord extends through the at least one flexible loop, and tensioning the cord reduces the size of the opening so that the proximal chute transitions from the opened condition to the closed condition. A locking device secures the tensioned cord so that the proximal chute is maintained in the closed condition.
The proximal chute may further include an aperture extending therethrough, and at least one pocket may have an open end attached to the proximal chute and an opposite closed end. The open end of the pocket circumferentially surrounds the aperture to permit access via the aperture to an interior of the pocket.
Claims Coverage
The document contains two independent claims. Across them, the core structure includes a distal ring, a transition tunnel, and a proximal chute that transitions between opened and closed conditions, with at least partial prevention of medical device egress; one claim adds a flexible loop, cord, and locking device, and the other adds an aperture and circumferentially surrounding pocket for access.
Delivery device with distal ring, transition tunnel, and proximal chute transitions
A delivery device configured to deliver a medical device into a surgical skin pocket comprising a distal ring, a transition tunnel sized to receive a medical device and coupled to the distal ring, and a proximal chute including an inner perimeter and an outer perimeter, the inner perimeter being coupled to the transition tunnel, the proximal chute being configured to transition between opened and closed conditions.
Flexible loop, cord, and locking device for closed-condition egress prevention
At least one flexible loop attached to the outer perimeter of the proximal chute, a cord extending through the at least one flexible loop, tensioning of the cord reducing a size of the opening and transitioning the proximal chute from the opened condition to the closed condition, and a locking device for securing the tensioned cord so that the proximal chute is maintained in the closed condition, with the closed condition configured to at least partially prevent the medical device from egressing the delivery device.
Aperture through proximal chute with circumferentially surrounding pocket for access
The proximal chute has an aperture extending therethrough, and the delivery device further comprises at least one pocket having an open end attached to the proximal chute and an opposite closed end, the open end of the pocket circumferentially surrounding the aperture to permit access via the aperture to an interior of the pocket.
Together, the independent claims cover a delivery device that uses a distal ring and transition tunnel to support delivery into a surgical skin pocket, while a proximal chute transitions between opened and closed conditions with an opening for receiving the medical device and a closed condition that at least partially prevents egress. One independent claim further specifies tensioning a cord through flexible loops and securing the tensioned cord with a locking device to maintain the closed condition, and the other independent claim adds an aperture through the proximal chute with a pocket whose open end circumferentially surrounds the aperture to permit access to the pocket interior.
Stated Advantages
Allows the proximal chute to transition from an opened condition that defines an opening for receiving the medical device to a closed condition that at least partially prevents the medical device from egressing the delivery device.
Documented Applications
Delivering a medical device into a surgical skin pocket.
Delivering pre-filled implants into the pocket.
Delivering unfilled implants into the pocket.
Orientation and delivery of a pre-filled implant using a manipulation pocket with an aperture in the proximal chute for access.
