Abstract
A medical device including a catheter body, a first elongate body, and a service loop ring. The catheter body has a catheter shaft. The first elongate body extends through at least part of the catheter shaft and is configured to move longitudinally in the catheter shaft. The first elongate body is looped through the service loop ring to form a service loop configured to expand and contract as the first elongate body moves longitudinally in the catheter shaft.
Claims13
A medical device, comprising:
- a handle defining a housing;
- a catheter body having a catheter shaft extending distally from the handle;
- a first elongate body that extends through at least part of the catheter shaft and is configured to move longitudinally in the catheter shaft and includes a service loop formed in a portion thereof, the service loop disposed within the housing and configured to expand and contract as the first elongate body moves longitudinally in the catheter shaft;
- and
- a tubular service loop ring disposed within the housing, the service loop ring having a first end, a second end opposite the first end, and a lumen extending from the first end to the second end, wherein the first elongate body includes a first portion passing through the first and second ends and the lumen of the service loop ring, and a second portion passing through the first and second ends and the lumen of the service loop ring, and crossing over the first portion of the first elongate body within the lumen of the service loop ring, and wherein the service loop is formed between the first portion and the second portion of the first elongate body and is located externally of the service loop ring.

A medical device, comprising:
- a handle;
- a housing disposed in the handle;
- a catheter shaft coupled to the housing;
- a guidewire situated at least partially in the catheter shaft and having a guidewire distal end that protrudes from the catheter shaft;
- an element movably coupled to the handle and secured to the guidewire to move the guidewire longitudinally in the catheter shaft;
- an injection coil situated at least partially in the catheter shaft and having a coil distal end engaged with the guidewire adjacent the guidewire distal end;
- and
- a tubular service loop ring disposed within the housing, the service loop ring having a first end, and opposite second end, and a lumen extending through the service loop ring from the first end to the second end, wherein the injection coil includes a first portion passing through the first and second ends and the lumen of the service loop ring, a second portion passing through the first and second ends and the lumen of the service loop ring and crossing over the first portion of the injection coil within the lumen of the service loop ring, and a service loop formed between the first portion of the injection coil and the second portion of the injection coil and located externally of the service loop ring, wherein the service loop is configured to expand and contract as the guidewire and the injection coil are moved longitudinally in the catheter shaft.
