Rapidly insertable central catheters, introducers, insertion devices including combinations and methods thereof
Rapidly insertable central catheters (RICCs), introducers, and insertion devices including combinations and methods thereof are disclosed. For example, a RICC system can include an introducer and a RICC insertion assembly including a RICC assembly disposed in a RICC insertion device. The RICC assembly can include a RICC, an access guidewire, and a splittable casing over a catheter tube of the RICC and the access guidewire forming a longitudinal composite. The RICC insertion device can include a frame and a nose cover forming a split channel that splits away from a through channel of a nose of the frame. The RICC insertion device can be configured for advancing the RICC assembly by rolling the longitudinal composite across roller wheels disposed in the frame. The through channel can be configured for advancing the catheter tube therethrough while the split channel can be configured for both splitting and passing the splittable casing therethrough.
Sheath assembly for insertion of a cord-shaped element, particularly a catheter, into the body of a patient
Sheath assembly for the insertion of a cord-shaped element, comprising an introducer sheath, and an auxiliary sheath for insertion into the introducer sheath together with the cord-shaped element. In some examples, the auxiliary sheath has a housing configured to detachably couple to the introducer sheath housing, and to detachably fasten the cord-shaped element with respect to the auxiliary sheath housing.
INTRODUCER SHEATH
An introducer sheath for providing access in a patient's body comprises a tubular body with a distal portion and a proximal portion, the proximal portion being configured to be inserted into the patient's body to allow a medical device to be inserted through the introducer sheath into the patient's body. In order for the introducer sheath to be removable from the patient, it can be separated along its length in a longitudinal direction. The introducer sheath further comprises at least a first handle which is pivotable about a fulcrum. The first handle has a first end portion and a free second end portion so as to form a lever, such that pivoting the handle about the fulcrum causes a contacting portion of the handle to act on a respective counter portion that is operatively connected to the distal portion of the tubular body. This creates a breaking force that causes the distal portion of the tubular body to break.
Sheath splitting apparatus
The present invention concerns a sheath splitting apparatus for use with a medical device delivery system for deploying a sheathed medical device. The sheath splitting apparatus comprising: a body 3 having a medical device pathway 11 for receiving a medical device, and one or more arm members having one or more guide elements 12 defining a sheath pathway for guiding sheath material removed from the sheathed medical device. At least a section of the one or more arm members is movable towards and away from the longitudinal axis of the medical device pathway.
Rapidly Insertable Central Catheters, Introducers, and Insertion Devices Including Combinations and Methods Thereof
Rapidly insertable central catheters (RICCs), introducers, and insertion devices including combinations and methods thereof are disclosed. For example, a RICC system can include an introducer and a RICC insertion assembly including a RICC assembly disposed in a RICC insertion device. The RICC assembly can include a RICC, an access guidewire, and a splittable casing over a catheter tube of the RICC and the access guidewire forming a longitudinal composite. The RICC insertion device can include a frame and a nose cover forming a split channel that splits away from a through channel of a nose of the frame. The RICC insertion device can be configured for advancing the RICC assembly by rolling the longitudinal composite across roller wheels disposed in the frame. The through channel can be configured for advancing the catheter tube therethrough while the split channel can be configured for both splitting and passing the splittable casing therethrough.
Peel away hemostasis valve
A hemostasis valve body provides strong sealing around a medical device during insertion of the medical device into a blood vessel, low forces for tearing, and stability during insertion of the medical devices as well as during peel away. The valve body comprises a first surface, a second surface opposite the first surface, an edge, helical slits, and a pair of longitudinal cuts. The helical slits are positioned at a center of the valve body and traverse the first surface to the second surface. The helical slits provide a seal around the medical device. Each respective longitudinal cut extends from the first surface partially through the valve body to a depth short of the second surface for at least part of a length of the respective longitudinal cut. The longitudinal cuts facilitate a separation of the valve body into two parts during a peel away action.
Splitable needle and dilator catheter placement device and associated methods
Disclosed herein is a catheter placement system including a splittable needle and dilator. The system can include a housing having one or more flexible sections and a pleated section. A user can grasp an elongate medical device using the flexible sections and transition the housing pleated section between an extended and collapsed configuration to urge the elongate medical device proximally or distally. The system can also include a needle retraction mechanism configured to split the needle long a longitudinal axis and roll up the separate portions to allow one or more elongate medical devices to pass therebetween. The system can also include a dilator splitter configured to separate a dilator along a longitudinal axis and radially displace the dilator portions to allow one or more elongate medical devices to pass therebetween. Advantageously, the system can maintain the elongate medical device in a sterile environment, mitigating the introduction of pathogens.
SHEATH ASSEMBLY FOR INSERTION OF A CORD-SHAPED ELEMENT, PARTICULARLY A CATHETER, INTO THE BODY OF A PATIENT
Sheath assembly for the insertion of a cord-shaped element, comprising an introducer sheath, and an auxiliary sheath for insertion into the introducer sheath together with the cord-shaped element. In some examples, the auxiliary sheath has a housing configured to detachably couple to the introducer sheath housing, and to detachably fasten the cord-shaped element with respect to the auxiliary sheath housing.
