Medical instrument with an atraumatic end
First Claim
1. A catheter for inserting in a body, said catheter comprising a proximal end, a distal end, a central section extending between said proximal end and said distal end and an internal lumen extending from said proximal end to said distal end through said central section, said distal end including a rigid bulbous tip with an outer diameter that is greater than an outer diameter of said central section.

Abstract
A catheter used to deliver or retrieve material from within a body. The catheter comprises a proximal end, a distal end and a central section extending between the proximal end and the distal end. The catheter also includes an internal lumen that extends from the proximal end to the distal end through the central section. The distal end includes a rigid bulbous tip with an outer diameter that is greater than an outer diameter of the central section. The rigid bulbous tip has a rounded, substantially spherical shape that is safer than the distal end of a traditional catheter. The bulbous tip does not include any sharp edges that could tear or otherwise perforate a passageway within a patient. As a result, the catheter is safer and it can be advanced within the patient without causing pain or injury.

15. A medical instrument for inserting into a body, said instrument comprising a proximal end, a distal end, a central section extending between said proximal and distal ends and an internal lumen extending from the proximal end to the distal end, said distal end including a portion having a outer diameter that is greater than an outer diameter of the central portion and having an outer wall being free of edges that could injure the body as the catheter is introduced or removed from the body.
