Abstract
A catheter including a continuous envelope forming an open-bore shaft. The envelope is characterized by a main longitudinal axis and a sagittal cross section. At least a portion of the sagittal cross section may be characterized by at least one asymmetric property that extends along the main longitudinal axis in a predetermined pattern.
Claims18
A catheter comprising a continuous envelope forming an open-bore shaft;
- said envelope is characterized by a main longitudinal axis and a sagittal cross section;
- wherein at least one of the following is being held true:
- a. at least a portion of said sagittal cross section is characterized by at least one asymmetric property;
- further wherein said asymmetric property extends along said main longitudinal axis according to predetermined pattern;
- b. at least one cross section of said shaft and/or tip comprises at least one reversibly invaginated sector, such that said catheter is characterized by (i) at least one collapsible configuration of a relatively rigid shaft and/or tip and small cross section, and (ii) at least one expandable configuration of a flexible shaft and larger cross section;
- c. at least a portion of said corneal cross section is characterized by at least one asymmetric property;
- further wherein said asymmetric property extends along said main longitudinal axis according to predetermined pattern;
- d. at least a portion of said transverse cross section is characterized by at least one asymmetric property;
- further wherein said asymmetric property extends along said main longitudinal axis according to predetermined pattern;
- and
- e. said envelope is characterized by a main longitudinal axis and a (i) sagittal cross section;
- (ii) corneal cross section;
- (iii) transverse cross section or any combination thereof, wherein at least a portion of either (i) said sagittal cross section;
- (ii) corneal cross section;
- (iii) transverse cross section or any combination thereof, is characterized by at least one asymmetric property;
- further wherein said asymmetric property extends along said main longitudinal axis according to predetermined pattern.
