Abstract
A catheter for delivering therapeutic to an injection site within the body is provided. This catheter can include a shaft having a proximal end, a distal end, and an infusion lumen extending therein; a penetrating member coupled to the shaft and extendable from the distal end of the shaft, and a stabilizer positioned towards the distal end of the shaft. The catheter could also include a delivery system, able to be calibrated to deliver therapeutic through an injection port at a rate less than the therapeutic absorption rate of the injection site.
Claims20
A catheter for delivering therapeutic to an injection site within the body, comprising:
- a shaft having a proximal end, a distal end, and an infusion lumen extending therein;
- a penetrating member coupled to the shaft and extendable from the distal end of the shaft, the penetrating member having an injection port and a piercing tip, wherein the penetrating member penetrates the injection site in a first direction, and wherein the injection port directs therapeutic in a second direction different from the first direction;
- and
- a stabilizer positioned towards the distal end of the shaft, wherein the stabilizer is adapted to maintain the distal end of the shaft against the injection site while the penetrating member penetrates the injection site.

- a penetrating member coupled to the shaft and extendable from the distal end of the shaft,
- the penetrating member having an injection port and a piercing tip, wherein the penetrating member penetrates the injection site in a first direction, and wherein the injection port directs therapeutic in a second direction different from the first direction;
- and
- a delivery system,
- the delivery system able to be calibrated to deliver therapeutic through the injection port at a rate less than the therapeutic absorption rate of the injection site.
A catheter injection system for delivering therapeutic to an injection site within the body, comprising:
- a shaft having a proximal end, a distal end, and an infusion lumen extending therein;
- a penetrating member coupled to the shaft and extendable from the distal end of the shaft, the penetrating member having an injection port and a piercing tip;
- and
- a stabilizer for maintaining the distal end of the shaft in a relatively fixed position while the penetrating member penetrates the injection site;
- wherein the penetrating member penetrates the injection site in a first direction, and wherein the injection port directs therapeutic in a second direction different from the first direction, said second direction is at an angle non-orthogonal and non-parallel to the first direction such that therapeutic leakage from the injection site is reduced.
